Alarm Type
Check or Shutdown Alarm (Pretrip Only)
Associated Alarm
Codes
Alarm Code 137 Check Damper Motor Heater Output
Component Description and Location
The damper solenoid is located in the damper box. It is connected to the damper door by means of mechanical
linkage.
Circuit Description
The damper solenoid circuit is a two wire circuit. The #29 wire connects the interface board connector J15 to one
side of the damper solenoid. The CHD wire connects the other side of the damper solenoid to chassis ground at
the ground plate near the unit battery. The suppression diode must be installed with the bar end of the diode
toward the #29 wire. The switch wires are routed in the Main Harness. Power to the #29 wire is supplied by
interface board fuse F6.
How Alarm is Set
1. This alarm is set if the measured shunt current is incorrect during non running pre-trip. Current is
measured with the output on and off.
2. The alarm is set as a Check alarm if the current is not within specifications when the solenoid is energized.
3. The alarm is set as a Shutdown alarm if the current does not return to 0 when the device is de-energized.
How Alarm is Cleared
This alarm is cleared manually.
Considerations
1. Power for this circuit requires the run relay to be energized.
Diagnostic Procedure
1. Check the operation of the damper door circuit using Interface Board Test Mode. Be sure the damper relay
LED 4 lights.
2. Use the HMI control panel amps gauge to check the current drawn by the damper solenoid while operating
the damper door with Interface Board Test Mode. The current draw should be approximately 6 amps.
3. Energize the damper solenoid using Interface Board Test Mode and check for battery voltage on the #29
circuit. If voltage is present at the damper solenoid and no current was measured in the step above
replace the damper solenoid.
4. If the unit is not configured correctly Alarm Code 137 may occur instead of Alarm Code 29.
