INSTALLATION PROCEDURES Figure.3-1 Clearance Allowance C. FRESH AIR SUPPLY When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make – up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problem and sail switch “fluttering” problems may result, as well as premature motor failure from overheating.
INSTALLATION PROCEDURES To compensate for the use of registers or louver used over the opening, this make – up air area must be increased by approximately thirty – three (33) percent. Make – up air openings should not be located in an area directly near where exhaust vents exit the building. It is not necessary to have a separate make – up air opening for each dryer. Common make up air openings are acceptable.
INSTALLATION PROCEDURES Outside Duct Work Protection To protect the outside end of horizontal duct work from the weather, a 90o elbow bent downward should be installed where the exhaust exits the building. If the duct work travels vertically up through the roof, it should be protected from the weather by using an 180o turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and the nearest obstruction.
INSTALLATION PROCEDURES Each dryer should be connected to an independently protected branch circuit. The dryer must be connected with copper wire only. Do not use aluminum wire, which could cause a fire hazard.

COMPONENT SYSTEM DESCRIPTIONS SECTION 4 COMPONENT SYSTEM DESCRIPTIONS A. BASKET/TUMBLER DRIVE SYSTEM The basket (tumbler) is supported and driven by eight (8) 11 inches diameter drive wheels. Two (2) of these wheels are attached to 1 – 3/4 inches diameter idler shaft, while the other two (2) are attached to a 1 – 3/4 inches diameter drive shaft. Each of the wheels is fastened to the shafts by a keyless locking bushing.
COMPONENT SYSTEM DESCRIPTIONS D. SAFETY DEVICES 1. Load Door Switches There are two (2) of these switches located under the main loading doors. These switches ensure that the doors are closed before the dryer can start. If the dryer is started when the load doors are open, the microprocessor controller (computer) LED display will show “door” 2. Lint Basket Switch This switch ensures that the lint basket is closed be before the dryer can start.
COMPONENT SYSTEM DESCRIPTIONS damper. The steam damper plate now covers the steam coil and allows room air to bypass the coil before entering the basket (tumbler) for a rapid cool down. The steam damper plate should open and close slowly and smoothly. This speed can be modulated by adjusting the needle valve knob. Turning the knob clockwise restricts the compressed airflow and slows down the steam damper movement. Counterclockwise adjustment speeds up the steam damper motion.
WARRANTY INFORMATION SECTION 5 WARRANTY INFORMATION A. WARRANTY For a copy of the commercial warranty covering your particular dryer (s), contact the distributor from whom you purchased the equipment and request dryer warranty form. NOTE: Whenever contacting the factory for warranty information, be sure to have the dryer’s model number and serial number available so that your inquiry can be handled in an expeditious manner. B.
ROUTINE MAINTENANCE SECTION 6 ROUTINE MAINTENANCE A. CLEANING A program and / or schedule should be established for periodic inspection, cleaning and removal of lint from various areas of the dryer, as well as throughout the duct work system. The frequency of cleaning can best be determined from experience at each location. Maximum operating efficiency is dependent upon proper air circulation. The accumulation of lint can restrict this air flow.
ROUTINE MAINTENANCE Every 6 Months Grease the two (2) 1 – 3 /4 inch pillow block bearings and the two (2) 1 – 3/4 inch pillow block bearings located in the dryer’s base. Use # 45 grease or equivalent. Grease the two (2) motors in the base with Chevron SR # 1 or 2 grease or equivalent unless otherwise stamped on the motor label. Check V – belts for tightness and wear. Retighten or replace if required. On steam dryers, clean steam coil fins.
ROUTINE MAINTENANCE WARNING The electric charge in the DC bus capacitor may be being charged even after the power is turned off. Therefore, it may take a long time until the DC link circuit voltage reaches a safety potential. Do not open the control circuit terminal block cover within 5 minutes after the power has been turned off. Then remove the control circuit and main circuit terminal block covers.
ROUTINE MAINTENANCE 1. DC bus capacitor Measure the capacitance of the DC bus capacitor as follows: The capacitance is displayed in the reduction ratio (%) of the initial value written in the inverter memory before shipment. Capacitance measurement procedure 1. Remove the RS485 communications card (option) from the inverter if it is mounted. Disconnect the DC bus link circuit to other inverters from terminals P (+) and N (-) of the main circuit if any.
OPERATING AND PROGRAMMING INSTRUCTIONS SECTION 8 OPERATING AND PROGRAMMING INSTRUCTIONS A. OPERATING INSTRUCTIONS NOTE: Before attempting to start the dryer make sure that the main door is closed and the lint drawer is securely in place. Microprocessor (Computer) Dryer 1. General description of the controller The DQ 01 is a user configurable microprocessor controller used to control drying machines.
OPERATING AND PROGRAMMING INSTRUCTIONS 2. Connecting the controller and the extension boards A dryer controller set always comprises a dryer controller CPU board, with inputs and outputs on board. Optionally, the controller can be expanded with extension boards to increase the number of available inputs and outputs. All print boards have to be connected to a power supply and to the inputs and outputs through the available connectors.
OPERATING AND PROGRAMMING INSTRUCTIONS Please note that the power supply is double rectified, so if 24VDC and 0VDC are switched the controller will still work without problems. The power supply monitoring (see chapter 6.5.4) will not work if 24VDC is connected to pin 2 and 0VDC is connected to pin 1.
OPERATING AND PROGRAMMING INSTRUCTIONS 2.
OPERATING AND PROGRAMMING INSTRUCTIONS Address: Every extension board connected to a controller must have a unique address. This address may vary between 1 and 8. The address can be set-up with the dipswitches on the extension board: Switch 1 OFF ON OFF ON OFF ON OFF ON Switch 2 OFF OFF ON ON OFF OFF ON ON Switch 3 OFF OFF OFF OFF ON ON ON ON Switch 4 OFF OFF OFF OFF OFF OFF OFF OFF Address 1 2 3 4 5 6 7 8 2.
OPERATING AND PROGRAMMING INSTRUCTIONS the start button is pushed directly after that, message 14 can be displayed because the air flow switch hasn’t reached the ‘off’ position yet. Input 4: Input overload This input should be used to connect all available motor overload protectors. The protectors should be connected in series so that the input is ‘on’ when no overload protection is active. The controller continuously checks this input and if the input is ‘off’, message 2 is displayed.
OPERATING AND PROGRAMMING INSTRUCTIONS If no overheat input is connected, this input should be connected to 24V, so it is always in the ‘on’ state. Input 10: Emergency stop and safety switches If an emergency stop switch and other safety switches are separately connected to the controller, input 10 should be used for this purpose. The controller will continuously check input 10 and if the input is in the ‘off’ state, message 1 will be displayed.
OPERATING AND PROGRAMMING INSTRUCTIONS 2.3.2 Output signals on the CPU board As described in chapter 2.1, the dryer CPU board has 8 digital relay outputs available to connect signals needed to control the dryer. Output 1: Heater unit reset This output can be used to connect a signal to reset the heater installation. Every time a new drying program is started, this output will be activated for the time adjusted in machine parameter 30 (see chapter ‘Machine parameters’).
OPERATING AND PROGRAMMING INSTRUCTIONS 2.4 Replacing the battery In chapter 2.1, a picture can be seen where the location of the battery is indicated. The battery is a CR2016 type, 3 Volt. Replacing the battery should be done with the power switched on. If power is switched off and the battery is taken out, all battery backed-up memory will be lost. The battery capacity is enough to retain all data for 1 year. The battery should replaced every year.
OPERATING AND PROGRAMMING INSTRUCTIONS 3. Display and buttons on the controller The layout of the control panel is: 1 2 13 3 12 4 11 5 6 10 9 8 7 In the picture above, buttons, button groups and the displays are indicated with a number. The following list describes the function of the displays and buttons. 1. Numeric display A large display which can be read from longer distance. Is used to display current alarm number and estimated cycle time remaining. See chapter 4.3. 2.
OPERATING AND PROGRAMMING INSTRUCTIONS NOTE: A pre-defined drying program or a single cycle program can only be chosen if there is no active drying cycle, a cool-down cycle or when a program is finished but there is still a batch inside the machine. In practice this means that this button only works if the machine is in the ‘ready to start’ state. 5. Start button This button is used to (re)start the machine and to reset alarm messages.
OPERATING AND PROGRAMMING INSTRUCTIONS The enter button is used to confirm a choice or an adjustment. For example, if another program is selected from the list, the enter button must be pushed to confirm the choice. This is the same in case a parameter value is adjusted. When a new value is entered, this value has to be confirmed with the enter button, otherwise the change in value will not be stored. The clear button is used to cancel an entered value.
OPERATING AND PROGRAMMING INSTRUCTIONS will be increased by 5 minutes. If the SHIFT button (see item 10) is pushed in combination with the DECREASE CYCLE TIME button, the current time remaining in the drying or cool-down cycle will be decreased by 5 minutes. Please note that these changes in time are temporary. They do not change the adjusted value in the active program. This means that in the next program cycle, the settings adjusted in the program cycle will be used again.
OPERATING AND PROGRAMMING INSTRUCTIONS 3.2 Display symbols Icon Description Symbol for 1st sensor (Drum temperature) Symbol for 2nd sensor (Inlet temperature) Symbol for Infra-red sensor (Garment temperature) Symbol for humidity sensor Dry time Cool down time Arrow keys limitation Plus and minus keys limitations Key pad icons. 4. Overview screen During normal operation, the display will show the overview screen.
OPERATING AND PROGRAMMING INSTRUCTIONS 4.1 Status line with temperature As explained above, the status line with temperature may look like: 24 / 75 °C Drying The symbol means that heating is active. The machine is warming up to reach or maintain the adjusted temperature. If the software temperature controller decides that heating should be off, the ‘+’ symbol will disappear and the symbol will be replaced by a symbol, indicating that the heater output is off.
OPERATING AND PROGRAMMING INSTRUCTIONS 4.1.3 Status line with humidity sensor If a humidity sensor is present (and set in the machine configuration), the humidity sensor is placed in the exhaust pipe. It can then measure the humidity of the outlet air to detect if the batch is dry. Program parameter 10 is used to determine if the batch is dry. If a humidity sensor is present, the 2nd line may look like: 24 / 75 °C 23 % The value on the right is the current measured air humidity by the humidity sensor.
OPERATING AND PROGRAMMING INSTRUCTIONS The yellow LED indicates the status of the heating output. If the LED is on, the heater is output is on, and when it is off, the heater output is also off. The red and green LED’s are used to indicate the current machine status. The LED function table for the red and green LED is: Red LED Green LED Meaning On Blinking A warning or alarm is active. The upper numeric display will toggle between ‘---‘and the alarm number. See chapter 7 for the available alarms.
OPERATING AND PROGRAMMING INSTRUCTIONS In this screen, a pre-defined program can be selected with the numeric buttons 0 to 9 or with the ARROW UP and the ARROW DOWN buttons. The currently selected program number, together with the program name is displayed in the lower line of the display. If the arrow buttons are used in combination with the SHIFT button, the selected program will be increased or decreased by 10.
OPERATING AND PROGRAMMING INSTRUCTIONS When cause of the alarm has been corrected, the alarm can be reset with the START button. After that, ‘Waiting for cycle restart’ will be displayed. The same will happen if the STOP button is pushed once. If the message ‘Waiting for cycle restart’ is displayed, the cycle can be restarted with the START button and the pause situation is cancelled. If, in this case, the STOP button is pushed, the complete program will be cancelled and the step described in chapter 5.

OPERATING AND PROGRAMMING INSTRUCTIONS 6.2 Delayed start In the DQ 01 controller it is possible to define a delayed start. If this menu item is chosen, the screen for entering the start delay will be displayed. In this screen the number of hours and minutes delay can be entered. Changing values can be done with the NUMERIC keys and with the PLUS and MINUS buttons. Changing the cursor to another edit-field can be done with the ARROW UP and/or ARROW DOWN buttons.
OPERATING AND PROGRAMMING INSTRUCTIONS may ask for a password. Password level 1 is necessary to be able to reset the counters of a program. If the clear button is pushed and the password level is sufficient, all counters of this program will be set to 0. 6.3.2 Counters per day With the counter set ‘Counters per day’, the user can read how many batches and how many operating minutes have been done on a certain day. The controller saves the production data of the last 50 days the machine has been used.
OPERATING AND PROGRAMMING INSTRUCTIONS As the name suggests non-resettable counters cannot be reset. Also they are saved in EEPROM memory and not in battery backed-up memory. This means that, unlike the other 3 counter sets, these counters will not be lost in case the battery is empty or removed. 6.4 Edit parameter menu The controller has 3 sets of parameters. There are parameters which can be adjusted specifically for a program, so a program can be set-up to process a specific material.
OPERATING AND PROGRAMMING INSTRUCTIONS (02) Min. drying time If the program is set to automatic drying (see parameter 1), this parameter will be available. This parameter is the minimum drying time in minutes. This time is started when the drying cycle is started. During this time the controller will not check if the current batch is dry. (03) Max. Drying time If the program is set to automatic drying (see parameter 1), this parameter will be available. This parameter is the maximum drying time in minutes.
OPERATING AND PROGRAMMING INSTRUCTIONS pieces which are currently dried. For example, if this parameter is set to 175°C, the heating output will be switched off when the inlet temperature sensor (sensor 2) measures a temperature higher than 175°C. (18) Cooldown time The maximum time the cool-down step may last. If the adjusted cool-down temperature (parameter 19) is not reached within this time, the program will finish anyway. (19) Cooldown temperature The target temperature in the cool-down step.
OPERATING AND PROGRAMMING INSTRUCTIONS (29) Anti crease funct. This parameter indicates if the anti-crease function is enabled in this program. If a program is finished, the drum will always stop for 2 minutes. If anti-crease is enabled, after these 2 minutes the drum will start to run again. This will continue until the door is opened. During anti-crease the blower will not be on. This means that if the drum motor is connected together with the blower motor, the anti-crease function cannot work. (32) Max.
OPERATING AND PROGRAMMING INSTRUCTIONS 6.4.3 Edit machine parameters The machine parameter list is a list with parameters which can be adjusted to set-up general parameters in the machine. These parameters are used for all programs. Because they are valid for all programs, machine parameters are only accessible via the level 2 password. In the ‘edit machine parameters’ screen parameters can be selected with the arrow buttons up and down.
OPERATING AND PROGRAMMING INSTRUCTIONS (11) RS485 Stationnr. The controller is equipped with a so-called RS485 port to communicate with a PC for downloading translations and monitoring. Every controller in a network must have a unique station number. This parameter is used to set the station number of this controller. (12) RS485 baudrate This parameter is used to adjust the communication speed of the RS485 port used for networking multiple controllers and communication with a PC.
OPERATING AND PROGRAMMING INSTRUCTIONS (31) Blower clean time When a program is started the output for an optional clean signal (like an air blast) for the blower will be activated (output 3). This parameter is the number of seconds the output will be on when starting a program. (32) Blower WYE del. If the machine is equipped with a star/delta switch to start the blower motor this parameter is the delay for switching the blower star/delta switch from off to on after restarting the blower.
OPERATING AND PROGRAMMING INSTRUCTIONS 6.5.2 View status of outputs The ‘View status of outputs’ screen can be used to check if the controller board is activating an output. Viewing the status of an output can be done while the machine is running. Selecting a module number and channel number is done in the same way as in the ‘View status of inputs’ screen (see chapter 6.5.1).
OPERATING AND PROGRAMMING INSTRUCTIONS 6.6 System set-up menu The ‘System set-up menu’ is a menu with items which are not directly related to the control functions of the machine itself but define the complete installation and user interface. The available items are used to set-up some extra features of the controller. 6.6.1 Adjust date & time Password level 1 is required to be able to adjust current date and current time.
OPERATING AND PROGRAMMING INSTRUCTIONS consuming process, the normal program cycle can be halted for a while. During the time needed to restore all factory settings, the beeper will sound continuously. Please note that restoring factory settings will restore the factory settings of all drying programs and the settings of the machine parameters. These parameters are set as described in chapter 8. Restoring factory settings does not change the configuration parameters.
OPERATING AND PROGRAMMING INSTRUCTIONS accessible with the highest password level. Usually, these parameters are adjusted once after installing the machine. If the configuration has been set-up properly during installation, there is no need to change the values unless there are changes to the physical installation. In the ‘edit machine configuration’ screen, a parameter can be selected with the arrow buttons up and down. A value can be changed with the plus and minus buttons, or with the numeric buttons.
OPERATING AND PROGRAMMING INSTRUCTIONS (12) Status output func This parameter sets the function of the status output (output number 2), which can be used to give a signal to an external system or for example to connect an alarm light. Value 0: Output on when a drying cycle or cool-down cycle is busy. In this case the output will be switched on when a drying cycle starts and will switch off when the program is finished.
OPERATING AND PROGRAMMING INSTRUCTIONS 6.9 Controller information The ‘Controller information’ screen shows the current hardware and software version, and the serial number of the controller. This information can, for example, be used to check if the correct version of the manual is being used as a reference. This information must also be provided with each support request. 7 Alarms If the machine detects an alarm or a warning a message will be displayed on the 2nd line of the overview screen.
OPERATING AND PROGRAMMING INSTRUCTIONS (6) Gas heater alarm The input for the error of the gas heater (input 14) is, or has been, in the ‘off’ state for minimum 3 seconds. This means the gas heater gives an error signal. (7) Fire suppression The input for fire suppression (input 15) is, or has been, in the ‘off’ state. This means the fire suppression contact is activated. (10) Rotation sensor time-out While the drum was running, the rotation sensor didn’t go from the ‘on’ to the ‘off’ state quickly enough.
OPERATING AND PROGRAMMING INSTRUCTIONS (18) Error power supply The 24V power supply is too low (below 20 Volts) or too high (above 40 Volts). Because this can cause damage to the controller, it has switched all outputs off. The actual power supply voltage can be checked at any time from the test program menu (see chapter 6.5.4). (19) Battery empty When starting up the controller checks if the battery backed-up memory is still ok. If not, this message will be displayed.
OPERATING AND PROGRAMMING INSTRUCTIONS (34) Maintenance request The maintenance request counter is 0 and the machine needs maintenance. The number of batches which can be done between 2 maintenance requests is adjustable with machine parameter 5).
