Troubleshooting the Liebert XDP

Symptom

Possible Cause

Check or Remedy

Pump Will Not Energize

No main power

Check L1, L2 and L3 for rated voltage.

Loose electrical connections

Tighten connections.

Overloads tripped

Allow pump to cool. Check amp draw.

Tripped circuit breaker

Check circuit breaker to pump(s).

Incorrect phase wiring

See

Table 13

Pump Will Not Start or

Run

No chilled water

Check and verify that there is supply chilled water to the

Liebert XDP.

Isolation valve(s) on pump suction

and/or discharge is closed.

Open all isolation valves completely during normal operation.

Supply chilled water is too high

Check and verify that the chilled water temperature setpoint is

at 50°F (10°C) or lower and that there is flow on the chilled

water side.

Liebert XD cooling modules are Off

Check Liebert XD cooling modules to make sure that they are

On prior to starting the Liebert XDP.

Low Refrigerant Temperature

(high dew point)

Check alarm(s) history on Liebert XDP. The Liebert XDP was

operating below the dew point for a significant amount of time.

Check humidity in conditioned space, lower humidity if

necessary to allow Liebert XDP to operate at a lower

temperature. (Disconnect must be switched to Off then back

On to allow Liebert XDP to reset itself).

Pressure switch not making contact

Check both differential pressure settings. If not within 6 psi, ± 1

psi (41kPa, ±7kPa; 0.41 bars, ±0.07bars) then manually

change accordingly.

Not enough charge

See

5.1 - Checklist for Liebert XDP Startup

Pump Will Not Start

Chilled water valve not closing

completely.

Wait at least 10 minutes before calibrating. Access the

Advanced Menu>Factory Settings>Calibrate Actuator.

Contact Liebert Services for assistance, 1-800-543-2778.

Pump Noisy

Cavitation due to vapor in pump

Check for adequate charge in system, refer to the User's

Manual.

5.1 - Checklist for Liebert XDP Startup

Worn motor bearings

Replace pump

Pump is rotating in reverse

See

Table 13

Liebert XDP (Pump)

Suddenly Stops

Low refrigerant temperature

1. Check humidity of the room along with the location of

remote sensors. Make sure that the sensors are not in a cold

area where there is insufficient air flow for accurate,

representative readings.

2. Chilled Water temperature is too cold.

3. Load is too light.

Loss of power

When power is restored, the Liebert XDP will automatically

restart.

Clogged filter dryer and/or impeller

Clean out debris

Leak in system - loss of charge

Check the entire system for leaks with a refrigerant sniffer.

Repair as necessary.

Low chilled water temperature alarm

and loss of flow Pump X alarm

Check supply chilled water temperature.

Supply refrigerant sensor failure

alarm

Check wiring.
Call service.

Clogged Filter Dryer

and/or Impeller

Debris or other contaminants in

refrigerant

Replace.

Pipe Rattle

Loose pipe connections

Check pipe connections.

Chilled Water Valve Not

Working

Motor operates but valve won't open

Check linkage for adjustment and be sure that it is tight on the

valve.

No 24 VAC power to motor

Check for 24 VAC between P52-1 and P52-4.

No signal from control

Check 24 VAC at P22-1 (close) or P22-3 (open).

Motor not operating

Unplug P22 from the board. Jumper P22-5 to P52-4 for

grounding, then jumper P22-1 to P52-1 to drive close. Remove

jumper to close and then jumper P22-3 to P52-1 to drive open.

If motor fails to work, replace it.
