∙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.
§SW3-1 – Set to ON if the Master Controller is at the end of the communications line. In a typical installation, the communications lines are terminated at the Master Controller and at the top level of Flashheads. In this case, this switch should be set ON.
2.2.2Flashhead Configuration
All of the configuration for the Flashhead in done on the digital controller board. Because of the high voltage present in the Flashhead, there are interlock switches and fuses as follows (Figure 1-2, Page 1-3):
∙S1 POWER Interlock Switch: Three-position push/pull switch. When the Flashhead door is opened, S1 interrupts AC line power to transformers T1 and T2 when using 120VAC single-phase power. (When using 2-phase AC power, S1 does not interrupt AC power to transformers T1 and T2.) When the Flashhead door is opened, the PWR ON lamp DS1 to turn off. Also interrupts power to relay K1, causing the high voltage to be shut off and the energy storage capacitors to discharge. When door is open and S1 is pulled out manually, the interlock is defeated, which allows the Flashhead to operate under power.
∙S2 MODE Interlock Switch: Three-position push/pull switch. When the Flashhead door is opened, transfers flash intensity mode select from remote control (by SGC-60 Master Controller) to local control using switch S3. When door is open and S2 is pulled out manually, the interlock is defeated, which allows the Flashhead to operate under remote mode control.
∙S3 MODE TEST Switch: Three-position rotary switch allows local flash intensity mode selection (Day, Twilight or Night) for the individual Flashhead, while not affecting the operation of any other Flashhead in the system.
∙F1 Main Power Line Fuse: Provides protection for AC power to transformer T1. Value varies with input AC line voltage. Refer to Section 7.0 for the correct fuse values. Honeywell provides the correct fuse for the supplied power configuration.
∙F2 Logic Power Line Fuse: Provides protection for the AC power to the logic transformer T2. Value varies with input line voltage. Refer to Section 7.0 for the correct fuse values. Honeywell provides the correct fuse for the supplied power configuration.
