3 Installation “easy” must only be installed and wired up by trained electricians or other persons familiar with the installation of electrical equipment. Danger of electric shock Never carry out electrical work on the device while the power supply is switched on.
Installation 30 For ease of wiring, leave a gap of at least 3 cm between “easy” terminals and the wall or adjacent devices. 30 30 30 1 2 왘 Check that “easy” is seated firmly. “easy” is mounted vertically on a top-hat rail in the same way. 22 08/00 AWB2528-1304-GB Mounting on top-hat rail 왘 Hook “easy” to the top edge of the top-hat rail and hinge into place while pressing down slightly as shown by the arrows.
Mounting Mounting on a mounting plate For a screw fixing, use a mounting plate that can be fitted on the back of “easy”. Mounting feet can be ordered as an accessory.
Installation Connecting the expansion device 1 2 3 24 08/00 AWB2528-1304-GB 4
Terminals Terminals Tools Slot-head screwdriver, width 3.5 mm, tightening torque 0.6 Nm. Cable cross-sections Solid 0.2 to 4 mm2 Flexible with ferrule: 0.2 (AWG 24) to 2.5 mm2 (AWG 12) Connecting the power supply For the technical data of both versions, “easy”DC with 24 V DC and “easy”-AC with standard voltages of 100 V to 240 V AC, refer to chapter 11 from page 197. The EASY600 models run a system test for five seconds after the power supply has been switched on.
Installation EASY...-AC-.E L N F1 E+ E- R1 ... R12 L N N 115/230 V ~ DANGER of electric shock with “easy”-AC units! With “easy” NEVER swap over the live (L) and neutral conductor (N) terminals as the interface will then carry the live (L) potential power of 230 V/115 V. There is a danger of electric shock if the plug is not properly connected or if conductive objects are inserted into the socket.

Installation Connecting the inputs Cable protection Both “easy” AC and DC versions require cable protection (F1) rated for at least 1 A (slow). When “easy” is switched on for the first time, its power supply circuit behaves like a capacitor. Use an appropriate device for switching on the power supply and do not use any reed relay contacts or proximity switches. “easy” inputs switch electronically.

Installation Connect the inputs, for example, to push-button actuators, switches or relay/contactor contacts. Input signal voltage range: OFF signal: 0 V to 40 V ON signal: 79 V to 264 V Input current R1 to R12 I1 to I6, I9 to I12: I7, I8: 0.5 mA/0.25 mA at 230 V/115 V 6 mA/4 mA at 230 V/115 V Cable lengths Severe interference to cables can cause inputs to signal 1 without a proper signal being applied.
Connecting the inputs L N 1A L N N I1 115/230 V h “easy”-AC Neon bulbs with a maximum residual current of 2 mA/1 mA at 230 V/115 V can be connected to I7 and I8. Always use neon bulbs that are operated with a separate N connection. Caution Do not use reed relay contacts on I7, I8. These may burn or melt due to the high inrush current of I7, I8. Two-wire proximity switches have a residual current on 0. If this residual current is too high, the input of “easy” may only detect the 1 signal.
Installation Increasing the input current The following input circuit can be used in order to prevent interference and also when using two-wire proximity switches: L N 1A 100 nF/275 V L N N I1 115/230 V AC When using a 100 nF capacitor the drop-off time of the input increases by 80 (66.6) ms at 50 (60) Hz. A resistor can be connected in series upstream of the circuit shown in order to restrict the inrush current.
Connecting the inputs Complete devices for increasing the input current are available, for example, from Felten & Guilleaume. L N 1A L N N I1 1 2 115/230 V AC F&G Z7-JC/KO 08/00 AWB2528-1304-GB The increased capacitance increases the dropout time by approx. 300 ms.
Installation Connecting “easy”-DC and “easy”-DA inputs Use input terminals I1 to I12 to connect push-button actuators, switches or 3 or 4-wire proximity switches. Given the high residual current, do not use 2-wire proximity switches. Input signal voltage range OFF signal: 0 V to 5 V ON signal: 15 V to 28.8 V Input current “easy”-DC: I1 to I6, I9 to I12: R1 to R12 3.3 mA at 24 V, I7, I8: 2.2 mA at 24 V “easy”-DA: I1 to I6: I7, I8: 3.3 mA at 12 V, 1.1 mA at 12 V L01 L01 +...

Consequently, more care must be taken when laying and connecting the signal lines. Incorrect switching states may occur if they are not connected correctly.
Installation suppressor circuit for motors and valves. If loads such as motors, solenoid valves or contactors are operated with “easy” via the same power feed, switching may result in interference on the analog input signals. The following four circuits contain examples of applications for analog value processing. Ensure that the reference potential is connected.

Connecting the outputs Connecting the outputs The Q output terminals function inside “easy” as isolated contacts. Q1 1 2 In the “easy” circuit diagram the relay coils are controlled via the corresponding output relays Q1 to Q4 or Q1 to Q8 (Q6). You can use the signal states of the output relays as make or break contacts in the “easy” circuit diagram to provide additional switching conditions.

The output current will increase in this case to a maximum of 2 A. Caution Please note the following when switching off inductive loads. Suppressed inductive loads cause less interference in the entire electrical system.
Connecting transistor outputs If inductive loads are not suppressed, only one inductive load should be switched off at any one time so as to prevent the driver blocks from possibly overheating. If in the event of an emergency stop the +24 V DC power supply is to be switched off by means of a contact, and if this would mean switching off more than one controlled output with an inductive load, then you must provide suppressor circuits for these loads (see the following diagrams). Q..

5 Drawing a Circuit Diagram with “easy” By working through the example in chapter 4 you should now have gained an initial impression of just how simple it is to create a circuit diagram in “easy”. This chapter describes the full range of “easy” functions and provides further examples of how to use “easy”.
Drawing a Circuit Diagram with “easy” Operation of “easy” The cursor buttons in the “easy” circuit diagram perform three functions. The current mode is indicated by the appearance of the flashing cursor. Move Enter Connect In Move mode you can use ÍÚ ú í to move the â cursor around the circuit diagram in order to select a circuit connection, contact or relay coil. Use OK to switch to Enter mode so that you I1 can enter or change a value at the current cursor position.
Operation of “easy” Contacts Contacts are used to modify the flow of current in the “easy” circuit diagram. Contacts such as make contacts carry a 1 signal when closed and 0 when open. Every contact in the “easy” circuit diagram can be defined as either a make contact or a break contact.
Drawing a Circuit Diagram with “easy” Relays “easy” has nine different types of relay for wiring in a circuit diagram. Relay type “easy” symbol EASY412 EASY600 Coil function Parameters “easy” output relay contact Q Q1...Q4 EASY618/619: X – Q1...Q6 EASY620/621: Q1...Q8 Marker relay contact M M1...M16 M1...M16 X – Timing relay contact T T1...T8 T1...T8 X X Counter relay contact C C1...C8 C1...C8 X X Time switch contact Ö Ö1...Ö4 Ö1...Ö4 – X Analog comparator relay A A1.
Operation of “easy” Insert relay contacts in the three contact fields. The first contact field is automatically connected to the voltage. Insert the relay coil to be controlled together with its function and designation in the coil field. Every line in the circuit diagram forms a circuit connection. EASY412 and EASY600 permit the connection of 41 and 121 circuit connections/ current paths respectively.
Drawing a Circuit Diagram with “easy” Saving and loading circuit diagrams There are two ways of saving circuit diagrams in “easy” externally: By saving to a memory card By saving to a PC running EASY-SOFT. Once they have been saved, programs can be reloaded into “easy”, edited and run. All circuit diagram data is saved in “easy”. In the event of a power failure the data will be retained until the next time it is overwritten or deleted.
Working with contacts and relays Conventional circuit S1 S2 K1 “easy” circuit diagram Connecting up “easy” Connect S1 to “easy” input terminal I1 Connect S2 to “easy” input terminal I3 Connect load H1 to “easy” output Q4 S1 or S2 switches on H1. “easy” circuit diagram I2u------ÄQ4 K1 H1 I3k First specify which input and output terminals you wish to use in your circuit. Depending on the model concerned “easy” has 8 or 12 input terminals and 4, 6 or 8 outputs.
Drawing a Circuit Diagram with “easy” Enter mode is used to modify the value of contact fields and coil fields. The value to be modified value flashes. If the field or section is empty, “easy” will enter contact I1 or the coil ÄQ1. 왘 Move the cursor using the buttons ú í ÍÚ to a contact or coil field. 왘 Press OK to switch to Enter mode. 왘 Use ú í to select the position you wish to change, or press OK to jump to the next position. 왘 Use Í Ú to modify the value of the position.
Working with contacts and relays Delete all the contacts and relay coils from the circuit connection 왘 Move the cursor using the buttons ú í ÍÚ to a contact or coil field. 왘 Press DEL. The contact or the relay coil will be deleted, together with any connections. Changing make contacts into break contacts Every relay contact in the “easy” circuit diagram can be defined as either a make contact or a break contact. 왘 Switch to Enter mode and move the cursor over the contact name. 왘 Press ALT.
Drawing a Circuit Diagram with “easy” 왘 Press ALT to switch to Connect mode. 왘 Use ú í to move the diagonal arrow between the contact fields and coil fields and ÍÚ to move between circuit connections. 왘 Press ALT to leave Connect mode. “easy” will leave Connect mode automatically when you move the diagonal arrow onto a contact field or coil field which has already been assigned.
Working with contacts and relays Close the delete operation with ALT or by moving the cursor to a contact or coil field. Inserting and deleting a circuit connection The “easy” circuit diagram shows four of the 41 or 121 circuit connections in the display at the same time. “easy” automatically scrolls up or down the display to show hidden circuit connections – even empty ones – if you move the cursor past the top or bottom of the display.
Drawing a Circuit Diagram with “easy” Delete circuit connection “easy” will only remove empty circuit connections, i.e. those without contacts or coils. 왘 Delete all the contacts and relay coils from the circuit connection. 왘 Position the cursor on the first contact field of the empty circuit connection. 왘 Press DEL. The subsequent circuit connection(s) will be “pulled up” and any existing links between circuit connections will be retained.

Working with contacts and relays Coil functions You can set the coil function to determine the switching behaviour of relay coils. The following coil functions are available for relays Q, M, S, D, “:” Circuit diagram symbol “easy” symbol Ä ä S R 08/00 AWB2528-1304-GB Coil function Example Contactor function ÄQ1,ÄD2, ÄS4,Ä:1 ÄM7 Impulse relay function äQ3,äM4, äD8,äS7 Set (latching) SQ8,SM2, SD3,SS4 Reset (unlatching) RQ4,RM5, RD7,RS3 Marker relay M is used as a “flag”.
Drawing a Circuit Diagram with “easy” To ensure a clear overview of all relay states only assign the same coil function once to a relay (ä, S, R). However, retentive coil functions such as ä, S, R can be used several times if required by the circuit diagram logic. Exception: The coil function can be used properly several times when using jumps to structure the circuit diagram. Rules for wiring relay coils Use the contactor or “impulse relay” function once only for each relay coil.
Working with contacts and relays Impulse relay The relay coil switches whenever the input signal changes from 0 to 1. The relay behaves like an impulse relay.

I1-I2----SQ1 ... ... I2-------RQ1 A latched relay is automatically switched off if the power fails or if the device is in Stop mode. Exception: Retentive coils retain signal 1 (see chapter 8, page 151). The function relays are used to simulate some of the devices used in conventional control systems.
Drawing a Circuit Diagram with “easy” A function relay is started via its relay coil or by evaluating a parameter. It switches the contact of the function relay according to its function and the set parameters. Current actual values are cleared if the power supply is switched off or if “easy” is switched to Stop mode. Exception: Retentive coils retain their state (see chapter 8, page 151). In timing and counter relays, it is also possible to change the switching behaviour via the coil functions.

Typical applications Switching conveyor belts on or off after a delay Detecting gaps in the switching of sensors in the event of a fault Automatic window shutter control with random switching times Timing relays, off-delayed with and without random switching The relay switches a contact immediately and then resets it after the setpoint delay has elapsed.
Drawing a Circuit Diagram with “easy” relay contact (B, C). If the time is set to zero, the contact follows immediately after the trigger signal. Typical applications Activating the deceleration of motors or fans Automatic lighting control for vacant buildings with random switching times Timing relays, single pulse The relay switches a contact for a time equal to the delay time set, regardless of the length of the trigger signal.
Timing relays Timing relays, flashing The relay closes and opens the relay contact alternately at the set flashing frequency. Ü Flash frequency = -------------1 --------------2 set time Example Set time: 0.2 s, Flash frequency = -----1----- = 2.5 Hz 0.4 s Signal diagram: on TRG on RES on t t t The trigger coil switches the flashing on and off. The flashing period starts with switch position “off”. The reset coil has priority over the trigger coil and always resets the relay contact.
Drawing a Circuit Diagram with “easy” Counter relays “easy” works with counter relays C1 to C8. D R C The counter relay increments or decrements signals and switches when the actual value is greater than or equal to the setpoint value. Values between 0000 and 9999 are possible. A counter relay can be controlled via the counting pulse CCx, counting direction DCx and reset RCx relay functions.
Counter relays Wiring a counter relay You integrate a counter relay into your circuit in the form of a contact and coil. Counter relay C1 receives counting pulses via the count coil CC1. The counting direction can be changed via the direction coil DC1: DC1 = 0: relay C1 counts up DC1 = 1: relay C1 counts down The Reset coil RC1 is used to reset the counter to the actual value 0. Contact C1 is used to process the result of the counter in the circuit diagram.
Drawing a Circuit Diagram with “easy” Determining counter frequency The maximum counter frequency depends on the length of the circuit diagram in “easy”. The number of contacts, coils and circuit connections used determines the run time (cycle time) required to process the “easy” circuit diagram. Example: When using EASY412-DC-TC with only three circuit connections for counting, resetting and outputting the result via the output, the counter frequency may be 100 Hz.
Time switch Values between 0000 and 9999 are possible. Parameter Coil function Meaning DIR Counting direction D DCx=0: count up DCx=1: count down CNT C Counting pulse RES R Reset The contactor symbol “Ä” before DIR, CNT and RES indicates whether the coil function is wired in the circuit diagram.

Drawing a Circuit Diagram with “easy” Each time switch has four channels which you can use to set four on and off times. The channels are set via the parameter display. The timer has a back-up battery. This means that it will continue to run in the event of a power failure, although the time switch relays will not switch. When the timer is disconnected from the power supply, the contacts remain open. Information on the battery back-up time are provided in chapter 11, page 197.

The shift pulse is switched on for exactly one cycle.
Drawing a Circuit Diagram with “easy” the storage positions are either set or reset in accordance with the series circuit. If the relay coils were activated, “easy” transfers the result to the contacts. M8 is now open once more. No new pulse can be formed until I1 has opened, since M7 is open for as long as I1 is closed. How does the value reach the shift register? When shift pulse M8 = “on”, the state of I2 (value) is transferred to storage position M1. If I2 is switched on, M1 is set.
Example circuits How can the value of a storage position be transferred? Use the make or break contact of storage positions M1 to M4 and wire them to an output relay or in the circuit diagram according to the task required. Running light An automatic running light can be created by slightly modifying the shift register circuit. One relay is always switched on. It starts at Q1, runs through to Q4 and then starts again at Q1. The marker relays for storage positions M1 to M4 are replaced by relays Q1 to Q4.
Drawing a Circuit Diagram with “easy” On the first pass, the value is switched on once by break contact M9. If Q1 is set, M9 is switched on. Once Q4 (the last storage position) has been switched on, the value is passed back to Q1. Try changing the times.

8 Retention It is a requirement of system and machine controllers for operating states or actual values to have retentive settings. What this means is that the values will be retained safely even after the supply voltage to a machine or system has been switched off and are also retained until the next time the actual value is overwritten. Requirements Permitted “easy” models Retentive actual values can be set with EASY412-D.-..
Retention The Retention setting always applies to all of the relays listed. Individual markers or function relays cannot be set retentively. The retentive data of EASY...-..-..X models with a fitted memory card is deleted when the power supply is switched on. Note The retentive data is kept every time the power supply is switched off. Data security is assured for 100 000 write cycles. Setting retention Requirement: In this case “easy” must be in Stop mode 왘 Switch to the System menu.

Retention Transfer retentive behaviour The setting for retentive behaviour is a circuit diagram setting; in other words, the setting of the retention menu may also under certain circumstances be transferred to the memory card or by uploading or downloading from the PC. Circuit diagram transfer (behaviour) EASY-SOFT, V 1.0 ➞ EASY412-D.-.. When the circuit diagram is transferred (downloaded), the retentive behaviour must be set manually on the EASY412-DC... unit.
Transfer retentive behaviour Changing the operating mode or the circuit diagram When the operating mode is changed or the “easy” circuit diagram is modified, the retentive data is normally saved together with their actual values. The actual values of relays no longer being used are also retained. Changing the operating mode If you change from Run to Stop and then back to Run, the actual values of the retentive data will be retained.
Retention Retentive auxiliary relays (markers) How the retention works The retentive markers M13, M14, M15, M16, D1 to D8 should be used in conjunction with the following coil functions. Set Impulse relay Reset S M.., D.. äM.., D.. R M.., D.. Note When the condition for resetting the marker is fulfilled, the marker is reset. It is essential that you note the following points: Due to the operation of “easy” the make contact will remain closed and the break contact will remain open.

Retentive auxiliary relays (markers) Range A: Q1 is switched on. The power supply is switched off. I1 is switched off. After the I1 is switched on, M15 is switched on and remains on. If the switching of I1 would switch off M15, the opposite would apply in the same way, and M15 would remain switched off. Range B: The power supply is switched off. I1 is switched on. After the switch on in the first “easy” cycle M15 is on.

Retentive timing relay Signal diagram: U I1 M1 M15 Q1 T2 t U = Supply voltage The circuit above functions in the same way as an impulse relay switch. The make contact will remain switched on in the first “easy” cycle if a coil is actuated by the make contact of a retentive marker (series and parallel connection both apply here too) and when the power is switched on, the reset condition for this retentive marker is on. The enable time T2 prevents Q1 from flickering.
Retention If these conditions are not fulfilled, the actual value will be cleared when the power is restored. If the R coil is actuated, the actual value will also be cleared.
Retentive timing relay Examples On-delayed, switching on-delayed with random range, retentive Task 1 (on-delayed): A drive motor must start up 30 seconds after the unit is first switched on. This task is implemented using the input which retains the 1 state on switch-on.

Retention Task 2 A conveyor belt is to be run empty. This no-load running is implemented by using a timing relay to keep the belt running following the STOP BELT command until the preset time has elapsed. If this procedure is interrupted by an interruption to the power supply, the belt is only permitted to run empty after switch-on for the remainder of the preset time period. This task is implemented using retentive markers.

Retention Retentive Up/down counters C7, C8 How the retention works The actual value of counter C7, C8 is retentive. When the condition for resetting the counter is satisfied, the actual value of the counter will be reset. Examples Counting parts Task 1 Parts are packed automatically in a shipping carton. Even if there is a power outage the correct number should still be packed into the carton. When the carton is full, the carton is removed manually and the counter reset.
Retentive Up/down counters C7, C8 Operating hours counter for maintenance intervals Task 2 Every 1000 hours the system or machine must be checked for possible defects. Filters and transmission oil must be changed and the bearings lubricated.
Retention M16 prevents C8 from accidentally receiving a counter pulse when the power is switched back on if there was a power outage during the counting period. Both M16 and C8 must retain their actual values at power outage so that the 1000 hours of operating with interruptions in the power supply can be counted. I1 (for example, a key-operated switch) is used to reset the counter.
Retentive Up/down counters C7, C8 Automatic lubrication at constant intervals and with a constant quantity of lubricant Task 3: 60 minutes after the last lubrication the bearings of a machine must be lubricated for 30 seconds. Contacts and relays used: T1 M15 Q1 T8 C8 Clock pulse Lubricate Valve Lubrication time Up counter Circuit diagram: Parameters entered: ---------TT1 Ü C8-------SM15 Ä T1-m15----CC8 M15------uTT8 hRC8 M15-t8----ÄQ1 S f g n00.
Retention Function of the “easy” circuit diagram: T1 provides the clock pulse. When a time of t = 0.5 seconds is selected the counting period amounts to 2 t = 1 s. One impulse is counted every second. The up counter C8 switches on valve Q1 via M15 at 3600 counting pulses (3600 s = 1 h). M15 resets C8 and prepares C8 for the next hour. To stop C8 continuing to count, the break contact of M15 blocks the counting pulses. T8 is actuated by means of M15. Once T8 has timed out, M15 and T8 will be reset.
9 “easy” circuit diagram cycle Inside “easy” In conventional control systems, a relay or contactor control processes all the circuit connections in parallel. The speed with which a contactor switches is thus dependent on the components used, and ranges from 15 to 40 ms for relay pick-up and dropout. With “easy” the circuit diagram is processed with a microprocessor that simulates the contacts and relays of the circuit concerned and thus processes all switching operations considerably faster.
Inside “easy” In the fourth segment, “easy” assigns the new switching states to all the coils in one pass. The fifth segment is outside the circuit diagram. “easy” uses this to “make contact” with the outside world: Output relays Q1 to Q.. are switched and inputs I1 to I.. are read once more. “easy” also copies all the new switching states to the status image register. “easy” only uses this status image for one cycle.
Determining the cycle time of “easy” circuit diagrams Example: Switching one cycle later This is the circuit diagram of a Circuit diagram: self-latching circuit. If I1 and I2 I1uI2----ÄQ1 are closed, the switching state of relay coil ÄQ1 is “latched” via Q1k contact Q1. 1st cycle: I1 and I2 are switched on. Coil ÄQ1 picks Start condition: I1, I2 switched on up. Q1 switched off. Contact Q1 remains switched off since “easy” evaluates from left to right.

Inside “easy” Delay times for inputs and outputs The time from reading the inputs and outputs to switching contacts in the circuit diagram can be set in “easy” via the delay time. S1 0V I1 This function is useful, for example, in order to ensure a clean switching signal despite contact bounce. “easy”-DC, “easy”-DA and “easy”-AC units function with different input voltages and therefore also have different evaluation methods and delay times.
Delay times for inputs and outputs If the debounce is switched off, “easy” responds to an input signal after just 0.25 ms. 1 S1 0 1 B B 0 A C Typical delay times with the debounce delay switched off are: On-delay for I1 to I12: 0.25 ms Off-delay for I1 to I6 and I9 to I12: 0.4 ms I7 and I8: 0.2 ms Check that there is no interference affecting the input signals when the debounce delay is switched off. “easy” will respond even to very short signals.
Inside “easy” The corresponding values for 60 Hz are given in brackets. S1 1 2 1 A 2 B If the debounce delay is switched on, “easy” checks at 40 ms (33 ms) intervals whether there is a halfwave present at an input terminal (1st and 2nd pulses in A). If “easy” detects two pulses in succession, the device switches on the corresponding input internally. If this is not the case, the input is switched off again as soon as “easy” does not detect two successive half-waves (1st and 2nd pulses in B).
Monitoring for short-circuit/ Overload with EASY..-D.-T.. I7 and I8: 20 ms (16.6 ms) with EASY EASY6..-AC-RC(X) S1 Monitoring for shortcircuit/Overload with EASY..-D.-T.. 1 1 A B “easy” switches the contact as soon as it detects a pulse (A). If no pulse is detected, “easy” switches off the contact (B). The procedure for changing the delay times is described in chapter 7 on page 145.
Inside “easy” Transfer EASY-D.-T.. ➞ Memory card ➞ EASY..-..-R... I16 is added during transfer of the circuit diagram into “easy” from the memory card. I16 appears as I16 and the logical state remains 0 = switched off (make contact). If I16 is changed in any way, only I1 to I8 can be entered. I16 can be deleted with the DEL button. Transfer EASY-D.-T.. ➞ EASY-SOFT (PC) EASY-SOFT, Version 1.0, cannot process input I16. I16 is deleted during the transfer to EASY-SOFT. EASY-SOFT, Version 1.
Monitoring for short-circuit/ Overload with EASY..-D.-T.. If a transistor output reports a fault, M16 is set by I16. The break contact of M16 switches off output Q1. M16 can be cleared by resetting the “easy” power supply. Example 2: Output of operating state I1-m16----ÄQ1 I16-------SM16 M16-------ÄQ4 êê êê êê êêê The above circuit functions as described in Example 1. An additional feature is that when an overload is detected the indicator light at Q4 is actuated. If Q4 has an overload, it would 'pulse'.
Inside “easy” Expanding EASY600 You can expand “easy” models EASY619/621-... locally using the expansion units EASY618-..-RE or EASY620-D.-TE or remotely – using the EASY200EASY coupling module. For this first install the units and connect the inputs and outputs (see chapter 3, Installation). Incorporate the inputs of the expansion units as contacts in the “easy” circuit diagram like the inputs in the basic unit. The input contacts possible are R1 to R12.
Expanding EASY600 Input and output reaction times of expansion units The debounce setting has no effect on the expansion unit.
Inside “easy” Example Power can be applied to the expansion unit later than the basic unit. This therefore means that the basic unit is switched to Run with the expansion unit missing. The “easy” circuit diagram below detects if the expansion unit is operational or not. I14-m1----Ä:8 ---------SM1 I14--------Ä:8 I1uI2----ÄQ1 Q1k As long as I14 is 1, the remaining circuit diagram is skipped. If I14 is 0, the circuit diagram is processed.

08/00 AWB2528-1304-GB Glossary Analog input The DC versions of “easy” have analog inputs I7 and I8. The input voltage range is 0 V to 10 V. Input data is evaluated by built-in analog comparator function relays. Circuit connections Each line in the circuit diagram display is a circuit connnection (EASY412: 41 circuit connections, EASY600: 121 circuit connections). Circuit diagram symbols As in conventional wiring, the circuit diagram is made up of circuit elements.
Glossary Timing relays Time switches Counters Analog comparators Text marker relays Impulse relay An impulse relay is a relay which changes its switching state and stays changed (latched) when a voltage is applied to the relay coil for a short time. Input The inputs are used to connect up external contacts. In the circuit diagram, inputs are evaluated via contacts I1 to I12 and R1 to R12. “easy” 24 V DC can also receive analog data via inputs I7 and I8.
Glossary retained, even if the power supply fails or is switched off. The memory card is inserted into the interface slot on the “easy” device. Operating buttons “easy” has eight operating buttons. These are used to select menu functions and create circuit diagrams. The large round button in the middle is used to move the cursor. 08/00 AWB2528-1304-GB DEL, ALT, ESC and OK all perform additional functions. Operating mode “easy” has two operating modes: RUN and STOP.
Glossary Power supply “easy”-AC is powered by AC voltage at 115 to 240 V AC, 50/60 Hz. The terminals are labelled “L” and “N”. “easy”-DC is powered by DC voltage at 24 V DC. The terminals are labelled “+24 V” and “0 V”. The terminals for the power feed are the first three terminals on the input side. Remote expansion I/O expansion with the expansion unit (e.g. EASY620-DC-TE) installed up to 30 m away from the basic unit. The EASY200-EASY coupling unit is fitted to the basic unit.
