Interlocks and Limit Switch Input
Combustion Air Switch Input
In this section, the necessary procedures are detailed to integrate
Note:
Shut off the power supply before
Caution:
Installation and maintenance must conform with the National Electrical Code and all other national and local codes and authorities having jurisdiction. Flame monitoring systems must be installed by a qualified, licensed technician.
Wire external interlock, control, and limit switches in series to this input. Guard against induced voltage levels to wiring connected to this input. In some extreme wiring runs, reduction of induced voltages may require a load (relay or light) connected to terminal 7 to avoid system error lockouts. This input is the power source for the valve and ignition output terminals. Be sure all switches wired to this input can handle the current required by the total of all loads connected to terminals 3, 4,and 5.
For purge and modulation models: Wire any switches and contacts in series to this terminal for proving air flow function and relating to the air failure light. Power must not be immediately present at terminal 6 when power is first applied to terminals 1 or 7.
If this terminal is not used, place a jumper between the combustion blower out- put (terminal 8) and the air switch input (terminal 6).
If the combustion air blower is controlled outside of
