Allen-Bradley® FanMaster™ Energy Saving Package Installation Manual - Publication FANM-IN001B-EN-P – December, 2009 PN-65329
Outside Air Damper Signal Out Of Range One of the following has occurred:
•
The polarity of the device wiring is incorrect.
•
Verify that the wiring is correct.
•
The outside air damper signal is above or
below the operating range (OOR) of the
device.
•
Check the damper position switch wiring for
damage and replace if necessary.
•
Check for loose wiring at the device or at
terminal block 2 in the FanMaster unit.
•
Check for loose or damaged wiring to the
damper actuator.
•
Check the signal from the BAS to the damper
actuator.
•
If an OOR still exists, replace the damper
position switch.
Mixed Air Temperature Low One of the following has occurred:
•
The mixed air temperature low limit may be
incorrectly configured.
•
Verify that the value in the “Supply Air Low
Limit” field on the
Cooling and Heating Setup
Screen on page C-10 is set appropriately.
•
The mixed air temperature is below the low
limit setpoint as configured in the FanMaster.
•
Verify that the fan drive is energized.
•
Verify that the fan is operational.
•
Verify that the damper actuator is operational.
•
Check the transmitter probe and wiring for
damage and replace if necessary.
•
Verify the temperature using a calibrated
thermometer. If the temperature is different
than the value displayed in the FanMaster,
replace the mixed air transmitter.
CO2 Level Above Setpoint The CO
2
level is above the high level setpoint as
configured in the FanMaster.
•
Check the sensor probe and wiring for
damage.
•
Check for loose wiring at the sensor or at
terminal block 2 in the FanMaster unit.
•
Check the CO
2
level using another calibrated
sensor. If the reading is different than the
value displayed in the FanMaster, replace the
CO
2
sensor.
