Airport Systems 2.2.1.
Airport Systems • SW2 – (Figure 2-10, Item 2, Page 2-25) This switch is used to set for Catenary operation (suspended cable warning lights) and for Dual systems (Red lights at night, and white strobes during the day). § SW2-1 – Set to ON (up) for Catenary system. § SW2-2 – Set to ON (up) for Dual system. § SW2-3 – Set to OFF (down). Reserved for future use. • SW3 – (Figure 2-10, Item 8, Page 2-25) This switch is used to set the termination resistor for the communications line.
Airport Systems 2.2.2.1 Power Configuration The Flashhead(s) are factory set for the correct AC input line voltage. However, the user shall verify that the AC line voltage selector block (located on the transformer board on top of transformer T1, Figure 1-2, Page 1-3) is labeled with the correct AC line voltage used at the site. For example, voltage selector block part number 77-3319 is labeled for 120VAC.
Airport Systems • SW3 – (Figure 2-11, Item 3, Page 2-26) Used to specify the ID number for the Flashhead. Each Flashhead must be set with a unique ID number as indicated on the installation drawings. There is a diagram next to the switch showing the values for the switch. The ID number is the total of the values of the switches set to OFF (negative binary). For example, to set ID #10, set SW3-2 (value 2) OFF (down) and SW3-4 (value 8) OFF (down) for a total of 10 (2+8).
Airport Systems 7. Refer to Figure 2-1 below. Dress the electrode wires away from the sides of the reflector. 8. Close and fasten the Flashhead cover. Figure 2-1: Flashtube Installation 2.3 2.3.1 Installation SGC-60 Master Controller The Master Controller is connected to Flashheads via the data communications cable provided by Honeywell. The length of this cable (up to 2500 feet) determines how far the Master Controller can be mounted from the Flashheads.
Airport Systems Typically, the Flashhead is mounted to a bracket, which is then attached to the structure. Honeywell can supply brackets for most types of installations. A detailed drawing for mounting the Flashhead is shown in Figure 2-3, Page 2-10. 2.3.2.1 Setting the Flashhead Elevation Flashheads must be mounted at the proper vertical angle to assure proper light output. Depending on the elevation of the light level, the Flashhead may need to be adjusted to reduce the amount of ground scatter.
Airport Systems 2.3.4 Cables and Junction Boxes The cables shall be properly supported and terminated in the junction boxes per the detailed description provided in section 2.4, page 2-11 of this document. Additional information regarding cables and junction box installation can be found on the drawing set for the lighting system. Particular attention should be paid to assure that the data cable shields are isolated from the junction box housings.

Airport Systems the junction box ports. Do not begin to run wire through a junction box port before a chase nipple or grommet is in place. 5. Before running the wire into a box insure the wire insulation will be protected from any sharp edges on the junction boxes. Pieces of carpet, wide copper braid, etc. can be fastened in place over sharp edges to protect wire insulation. 6.
Airport Systems (f) (g) and the connection should be at the top end of the junction box. Wiring from ports in the sides of junction boxes should also be made such that the wire nuts are at the top of the junction box with the wire nut openings pointing downward, (see Figure 2-6, Page 2-19) for proper moisture protection. Move down to the next intermediate (strain relief) junction box and pull enough of the wiring into the box to provide for the proper installation of the strain relief mechanism.
Airport Systems 2.4.7 Junction Box Details This section will detail the proper wire interconnection details for the input voltage and data cable to the flashhead pigtail cable. These connections are very important to the proper operation of the lighting system. The flashhead pigtail contains all the wires required for proper interconnection between the conduit wiring and flashhead. Additional reference materials can be found on the High Intensity Lighting system drawing set.

Airport Systems Figure 2-7: Flex Conduit Installation Detail SG-60 High Intensity Strobe System 2-20 Manual EPM-00000019 Rev A
Airport Systems The flex conduit will need to be properly mounted to the horizontal and vertical struts by way of the supplied 20-inch cable ties. These cable ties should be placed at a minimum of 3 feet apart for proper bonding to the tower structure. The distance between the cable ties may need to be reduced if the installer sees that the 3-foot distance will not allow for proper bonding and securing to the tower.
Airport Systems Item 6 is a shield drain wire that will not be used for interconnection. This wire should be cut off flush from the cable when the outer jacket is stripped back for interconnection of the system. The following section is a guideline to a proper installation of the WC000001 cable. Please follow this guideline to ensure a proper installation and interconnection in the junction box. 1. Strip back at least 16” of the outer jacket of the WC000001 cable.
Airport Systems 9. The power wires should be spliced together using split bolt connectors. The data wires should be spliced together using Scotch® Twist Lock connectors. After splicing, ensure all wires are secure by pulling on each wire. Wrap each connection with at least 6 wraps of Scotch 33+ tape or equivalent for moisture protection. All connection ends should be located in the upper corners of the junction box with all closed end of the connector pointing up. See Figure 2-6, Page 2-19 for reference.

Airport Systems for normal operation. If any test did not pass, please consult SECTION 4. TROUBLESHOOTING in this manual or call Honeywell Technical Support at (805) 5815591.
Airport Systems SECTION 3. PRINCIPLES OF OPERATION 3.1 Overall Description The SG-60 High Intensity Obstruction Lighting System meets the requirements of the FAA Advisory Circular 150/5345-43E. Depending on system configuration, the Flashheads are either type L-856 (simultaneous flashing, 40 flashes per minute (FPM)) or type L-857 (catenary flash pattern 60 FPM).
Airport Systems energy storage capacitors discharge rapidly through the flashtube. The high discharge current briefly heats the xenon gas to great temperatures, producing a bright flash. The short-circuit output current of the T1 transformer is limited to less than the flashtube's shut-off current. Once the capacitors discharge below a certain level, the current flowing through the tube cannot keep the xenon gas ionized, and the flashtube becomes a non-conductor and shuts off (self-extinguishes).
Airport Systems WARNING! HIGH VOLTAGE is on the energy storage capacitors C1, C2, C3A and C3B when the High Voltage Indicator DS1 indicator is lit! (DS1 is the neon lamp located on the High Voltage & Trigger board - do not confuse the High Voltage Indicator DS1, with the PWR ON lamp DS1.) It is possible to have high voltage on the energy storage capacitors even if all AC power has been removed from the system, even though the system is designed to drain the energy storage capacitors when power is removed.
Airport Systems The Digital Board functions are discussed in more detail below. 3.2.2.1 Power Supplies The Digital board rectifies (DB1) and filters (C4) the 24VAC output of the Flashhead T2 transformer, and uses the resulting unregulated voltage to power the K1, K2, and K3 relays. The K3 relay coil is wired directly to this supply. K3 will be energized whenever power is supplied to the digital board. Power to the K1 and K2 relay coils is controlled by the micro-controller.
Airport Systems position is shown on the board silkscreen. Note that ON means zero, and that OFF means the indicated value (negative binary). The Digital Board will only transmit a reply when its number is specified by the Master Controller. The Digital Board monitors its transmission quality by reading the transmission as it sends it. The green LED DS3 indicates the current communications status. It is updated after every flash.
Airport Systems 3.2.2.4 Flash Control To fire the flashtube, the Digital Board pulls down the trigger request line (P2-17) for about 500uS. This signals the Trigger/High-Voltage Card to trigger the flashtube. The Digital Board will issue its trigger request on a T2 zero-crossing. (Normally, the first zero-crossing it detects after receiving a flash request from the Master Controller.) In Day and Twilight modes, the Digital Board will issue a single trigger request.
Airport Systems 3.2.3.1 High Voltage Rectification This section of the Trigger/High-Voltage Board provides the DC to charge the energy storage capacitors that power the flashtube. The high voltage AC from the ferro-resonant power transformer T1 pins T1-7 and T1-8 is output to the Trigger/High-Voltage board through the Flashhead motherboard pins E5 and E6, respectively. The high-power diode bridge DB1 rectifies the incoming 2000Vp-p voltage to pulsed 2000VDC.
Airport Systems 3.3 3.3.1 SGC-60 Master Controller Power Supply The Master Controller input power is connected to PB1, which then feeds transformer T1 (under the switch panel). The Master Controller can accept a number of input voltages, depending on the primary tap connections to T1, and will operate at 50 or 60 Hz. The T1 transformer output provides 12VAC to the Master Controller circuit board PCB1 (T1-17 and T1-18 connecting to PCB1 TB1-1 and TB1-2).
Airport Systems The Master Controller gives previously good Flashheads four chances to reply (addressing that Flashhead repeatedly), before marking them bad. Previously bad Flashheads are given one chance to reply OK before moving on to the next Flashhead. The Master Controller checks the status of each Flashhead in order of increasing flashhead number, cycling repeatedly through the total number of selected Flashheads. You can set the number of Flashheads monitored using DIP Switch SW1.
Airport Systems during the daytime. In this case, the Master Controller will briefly try the Red Lights each night until the top beacon is repaired. Troubleshooting Tip: To check system communications independent of most Flashhead failures, place a jumper across TB6-1 and TB6-2, set SW2-2 On, and select Local Night Mode from the switch panel. Because an Off Mode "flash" cannot fail, all the Flashheads will reply OK if they can.
