F. START-UP FAILURES

PRIMARY MESSAGE SECONDARY MESSAGE ALARM MESSAGE/PRIMARY CAUSE ADDITIONAL CAUSE/REMEDY

FAILURE TO START NO OIL PRESSURE OILPD VALUE exceeded limit of [LIMIT]*.

Check oil ﬁlter, oil solenoid or shutoff valve.

Check solenoid valve operation. Check for

closed oil supply valves. Check oil ﬁlter.

Check for low oil temperature. Check trans-

ducer accuracy. Check oil supply valves,

oil ﬁlter, low oil temperature, transducer ac-

curacy, entering condenser water tem-

perature, and hot gas bypass.

FAILURE TO START OIL PRESS SENSOR FAULT OILP Check oil pressure transducer. Check for excessive refrigerant in oil sump.

Check transducer for power supply. Check

wiring. Replace transducer if necessary.

FAILURE TO START LOW CHILLED WATER FLOW EVFL Evap Flow Fault: Check water pump/

ﬂow switch.

Verify chilled water ﬂow. Make sure pump

is operating properly. Check wiring to flow

switch. Check through controls test for

proper switch operation.

FAILURE TO START LOW CONDENSER

WATER FLOW

CDFL Cond. Flow Fault: Check water

pump/ﬂow switch.

Same as above.

FAILURE TO START STARTER FAULT STR FLT Starter Fault: Check Starter for

Fault Source.

Starter fault switch has opened. Check

starter for ground fault, voltage trip, tem-

perature trip, etc.

FAILURE TO START STARTER OVERLOAD TRIP STR FLT Starter Overload Trip: Check

amps calibration/reset overload.

Reset overloads before restart. Check mo-

tor current calibration.

FAILURE TO START LINE VOLTAGE DROPOUT V P Single-Cycle Dropout Detected:

Check voltage supply.

Check voltage supply. Check transform-

ers for supply. Check with utility if voltage

supply is erratic. Monitor must be in-

stalled to conﬁrm consistent, single-cycle

dropouts.

FAILURE TO START HIGH CONDENSER PRESSURE CRP High Condenser Pressure: Check

switch and water temp/ﬂow.

Check for proper design condenser ﬂow

and temperature. Check condenser ap-

proach. Check 2C auxiliary contacts.

FAILURE TO START EXCESS ACCELERATION TIME CA P Excess Acceleration: Check slide

valve closure at start-up.

Check that slide valve is opened at start-

up. Check starter for proper operation. Re-

duce unit pressure if possible. Check power

supply.

FAILURE TO START STARTER TRANSITION FAULT RUN AUX Starter Transition Fault: Check

1CR/1M/Interlock mechanism

Check starter for proper operation. Run

contact failed to close.

FAILURE TO START 1CR AUX CONTACT FAULT CR AUX Starter Contact Fault: Check

1CR/1M aux. contacts.

Check starter for proper operation. Start

contact failed to close.

FAILURE TO START MOTOR AMPS NOT SENSED CA P Motor Amps Not Sensed: Check

motor load signal.

Check for proper motor amps signal to

SMM.

FAILURE TO START MOTOR WIRING INCORRECT Check motor wiring for phase reversal. Check incoming power leads to starter.

FAILURE TO START LOW OIL PRESSURE OILPD VALUE exceeded limit of [LIMIT].

Check oil system, oil solenoid and

transducer.

Minimum oil pressure requirement was not

met during the ﬁrst 120 seconds of start-

up. Check entering condenser water tem-

perature requirement. See Table 1.

FAILURE TO START CHECK REFRIGERANT TYPE STARTUP TERMINATED: Check refrig-

erant type

Check for proper refrigerant

conﬁguration.

*[LIMIT] is shown on the LID as temperature, pressure, voltage, etc., predeﬁned or selected by the operator as an override or an alert.
