OPERATION
default. HPF can be caused by lack of seawater flow due to a dirty strainer, pump being airlocked or seawater lines in need of
maintenance.
LAC – L
OW
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 – L
OW
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 50°, or faulty low
pressure switch.
OCA – O
VER
If the auger current exceeds 1.3 amps for 230VAC or 2.6 amps for 115VAC 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. 115VAC systems must see 2.6 amps for
1 second to trip the OCA; 230VAC/60Hz and 220VAC/50Hz systems must see 1.3 amps for 1 second to trip OCA.
OCC – O
VERLOAD
If the compressor current exceeds 18 amps for 230VAC or 36 amps for 115VAC 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 – A
UGER
Not applicable with the EI540D.
UCA – U
NDER
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.
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.
UCC – U
NDER
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.
