Adjusting the Output Timing: Refer to Figure 2
The Output Circuit Timing is adjustable from 0 to 5 minutes. Turning either circuit timing adjustment pot in a
clockwise manner will result in an increase of output time delay.
Output Wiring Configurations:
The Unit is factory configured as a 24-vac output. One to five output terminals are provided based on specifications
for the Unit. See page 5 for typical wiring schematics. Do not attempt to modify the unit to accept other than
voltage outputs as specified for the unit. To replace a PC Board not configured correctly for a specific application,
contact the factory or a local representative.
Installing the Electrical Conduit:
Knockout holes for connecting the electrical conduits are located at the top left and right of the Wall Box.
•
Connect rigid conduit for the required 120-vac electrical service to the upper left top of the enclosure at the
junction box.
•
Connect conduit for the output power to the upper right top of the enclosure.
Wiring the Unit:
Important!
Verify that the electrical supply is disconnected prior to connecting wiring to the Gas Sensor.
To wire the Controller:
1.
Remove the junction box cover.
2.
Make final connections to the 120-vac electrical service to wiring within the junction box. Verify that line
wiring (Black), neutral (White), and ground wire (Green) are correctly connected.
Minimum recommended wire size is 14 AWG.
3.
Replace the junction box cover before activating or testing the unit.
Connecting the Wall Panel to the Circuit Board; Mounting the Panel:
Wiring from the Control Panel Plugs into the 15 Pin Socket adjacent to the Transformer. If a Horn is provided, it
plugs into J 4.
