Eskimo Ice Installation & Operation Manual OPERATION
L-3152 ENGLISH 15
LAC – LOW AC LINE VOLTAGE
If the line voltage to unit is less than value selected in the programmable parameter for 5 minutes continuously the unit will stop
operation. The compressor delay is started and the unit will restart at the end of the delay if the voltage is greater than the value
selected in the programmable parameter. Parameter default is set to off.
LPF – LOW PRESSURE REFRIGERANT
If the Low Pressure Refrigerant Switch is open during production for 60 seconds, the display will show LPF fault and the Low
Pressure LED will light. The compressor delay is then activated for restart. The auger will continue to run for the duration of the
auger delay. At the end of the compressor delay the unit will show dLY beginning the restart routine. This switch is checked at
the start of a cycle and during operation. The compressor delay begins from the moment the switch is opened. Three faults in a
30 minute period will result in a lockout. LPF can be caused by, Low refrigerant levels, Seawater below 45°, or faulty low
pressure switch.
OCA – OVER CURRENT AUGER AND ICE DELIVERY PROBLEM
If the auger current exceeds 3.0 amps for 230VAC equipment for ~500ms the unit will stop all operation and lockout. For Eskimo
Ice models without a spout switch, the system relies on the amp reading of the auger motor to detect an ice clog and/or ice
delivery problem along with an overload and/or bad auger motor. 230VAC/60Hz and 220VAC/50Hz systems must see 3 amps
for 1 second to trip OCA.
OCC – OVERLOAD CURRENT COMPRESSOR
If the compressor current exceeds 30 amps for 230VAC equipment for ~500 ms the unit will stop the compressor. Auger
operation will continue for the duration of the auger delay then stop and lock out.
SPt – AUGER SPOUT BLOCKAGE
If the spout switch opens for ~100ms during production the SPt fault will show on the display and the Ice Flow LED will light. All
operation will stop including the auger. The blockage must be removed for production to restart. The maximum number of faults
that can occur in a 30 minute period is set for 3 by default. SPt fault can be caused by an improper delivery hose run, so make
sure the hose run goes up hill from the auger spout and does not have any 90°, sharp turns, or menders installed, and make
sure the surface where the delivery hose meets the thruhull is smooth to avoid trapping ice.
UCA – UNDER CURRENT AUGER
If the auger current is less than the default value .5 amps for 1 second the unit will stop all operation and lock out. UCA fault can
be caused by over voltage, open wire or open thermal overload.
UCC – UNDER CURRENT COMPRESSOR
If the compressor current is less than the default value of 5 amps (115 volt) or 2 amps (230 volt) for ~500 ms the unit will stop
operation and lock out. The auger will continue to run for the duration of the auger delay. UCC fault can be caused by over
voltage or open wire.
NOTE
If you experience erratic behavior such as reoccurring nuisance faults or erratic display behavior reboot the system by
shutting off at breaker for 30 seconds and powering back up. This should clear any glitches caused by power surge,
spikes or brown outs.
