HIGH CW TEMP
—Activated when the Supply CW sensor reads the chilled water temperature above the
user-specified alarm setpoint. This alarm will reset when the reading from the refrigerant temperature
sensor drops 5°F (2.8°C) below the user-specified setpoint and the alarm has been acknowledged.
HIGH DEW POINT
—Activates when the calculated dew point at either Sensor A or B exceeds the user-
specified alarm setpoint. The alarm will reset when the calculated room dew point from both Sensor A and
Sensor B is 2°F (1.1°C) below the setpoint and the alarm has been acknowledged.
HIGH REFRIGERANT TEMP
—Activated when the refrigerant temperature sensor reads the refrigerant
temperature above the user-specified alarm setpoint. This alarm will reset when the reading from the
refrigerant temperature sensor drops 2°F (1.1°C) below the user-specified setpoint and the alarm has been
acknowledged.
HIGH TEMP SENSOR A
—Activated when the reading from Sensor A is above the user-specified alarm
setpoint. The alarm will reset when the reading from Sensor A drops 2°F (1.1°C) below the setpoint and the
alarm has been acknowledged.
HIGH TEMP SENSOR B
—Activated when the reading from Sensor A is above the user-specified alarm
setpoint. The alarm will reset when the reading from Sensor A drops 2°F (1.1°C) below the setpoint and the
alarm has been acknowledged.
LOSS OF FLOW PUMP 1
—Activated when Pump 1 is commanded to run and the differential pressure
switch does not sense differential pressure (set at 6 psi; 41kPa; 0.41 bars). After attempting to start Pump 1
three times, the Liebert XDP will automatically switch to the other pump to establish flow. This alarm will
reset when flow has been established on Pump 1 and the alarm has been acknowledged.
LOSS OF FLOW PUMP 2
—Activated when Pump 2 is commanded to run and the differential pressure
switch does not sense differential pressure (set at 6 psi; 41kPa; 0.41 bars). After attempting to start Pump 2
three times, the Liebert XDP will automatically switch to the other pump to establish flow. This alarm will
reset when flow has been established on Pump 2 and the alarm has been acknowledged.
LOW MEMORY
—Activated when the control board is low in memory resources. This alarm rests
automatically as soon as memory consumption falls below the threshold.
LOW REFRIGERANT TEMP
—Activated when the supply refrigerant temperature sensor temperature
reading drops below the higher of the two calculated dew points, assuming that neither Sensor A or
Sensor B has a sensor failure alarm. This alarm will reset when the refrigerant temperature sensor reads
the refrigerant temperature above both of the two calculated dew points and the alarm has been
acknowledged. This alarm can lock the unit Off. If this occurs, the main power must be cycled, or the Low
Refrig Temp Alarm Code in the Service Diagnostics menu must be reset to 0.
LOW TEMP SENSOR A
—Activated when the reading from Sensor A drops below the user-specified alarm
setpoint. The alarm will reset when the reading from Sensor A rises 2°F (1.1°C) above the setpoint and the
alarm has been acknowledged.
LOW TEMP SENSOR B
—Activated when the reading from Sensor B drops below the user-specified alarm
setpoint. The alarm will reset when the reading from Sensor B rises 2°F (1.1°C) above the setpoint and the
alarm has been acknowledged.
NODEX CONDENSATION DETEC
—Activated when condensation is detected on a smart module at CAN
node ID X, where X is a value ranging from 81 to 100. This alarm resets when condensate is no longer
detected. The main power must be cycled off to remove the 4°F (2.2°C) offset value.
NODEX FAN FAILURE
—Activated when a fan failure occurs on a smart module at CAN node ID X, where X
is a value ranging from 81 to 100. The alarm will rest when the fan returns to normal operation.
