MISCELLANEOUS ALARMS

Motorized Damper Fault Critical (This is an Optional assembly.) If installed, the alarm is

asserted if the air isolation damper has not been opened/

closed in two minutes after commanded to open/close.

• Verify that the damper is not obstructed.

• Check the wiring.

• Service the damper.

• Replace the (field installed) actuator if needed.

Differential Pressure Sensor

Fault

Critical • Check the wiring.

• Ensure that the sensor tubing is connected properly and

the tubing is not damaged.

• Check the sensor calibration.

• Replace the sensor if needed.

Conductivity Sensor Fault

MIM/RIM (Frame master and

redundant controllers)

Warning The conductivity sensor not is functioning properly,

• Check the wiring.

• Replace the sensor if needed.

Module # [1…N] DX Not

Available

Critical Identify and correct the DX fault within the Module.

Conductivity Sensors not

Calibrated

Warning • Service and calibrate the conductivity sensors.

• Consult the documentation for the conductivity

transmitter for additional troubleshooting and diagnosis.
