Alarm Message/Primary
Cause
OILPD [VALUE] exceeded limit
of [LIMIT]*. Check oil pump sys-
tem.
OILPD [VALUE] exceeded limit
of [LIMIT]*. Check oil pressure
sensor.
EVFL Evap Flow Fault: Check
water pump/flow switch.
CDFL Cond. Flow Fault: Check
water pump/flow switch.
STR FLT Starter Fault: Check
Starter for Fault Source.
STR FLT Starter Overload
Trip: Check amps calibration/
reset overload.
V P Single-Cycle Dropout
Detected: Check voltage sup-
ply.
High Condenser Pressure
[LIMIT]: Check switch 2C aux,
and water temperature/flow.
CA P Excess Acceleration:
Check guide vane closure at
start-up.
Additional Cause/Remedy
Check for closed oil supply valves.
Check oil filter. Check for low oil tem-
perature. Check transducer accuracy.
Check for excessive refrigerant in oil
sump. Run oil pump manually for 5 min-
utes. Check transducer calibration.
Check cooler pressure transducer cali-
bration. Check wiring. Replace trans-
ducer if necessary.
Check wiring to flow switch. Check
through Control Test for proper switch
operation.
Check wiring to flow switch. Check
through Control Test for proper switch
operation.
A starter protective device has faulted.
Check starter for ground fault, voltage
trip, temperature trip, etc.
Reset overloads before restart.
Check voltage supply. Check trans-
formers for supply. Check with utility if
voltage supply is erratic. Monitor must
be installed to confirm consistent, sin-
gle-cycle dropouts. Check low oil pres-
sure switch.
Check for proper design condenser flow
and temperature. Check condenser
approach. Check 2C auxiliary contacts
on oil sump starter. Check high pres-
sure switch.
Check that guide vanes are closed at
start-up. Check starter for proper opera-
tion. Reduce unit pressure if possible.
