Fault Conditions
LOW WATER SHUTDOWN
If during the ice making cycle the water drops to a point
where the low float switch is open for 5 continuous seconds
the compressor and evaporator gear motor de-energize.
The control board starts a 15 minute time delay and
energizes the SAFETY 2 LED to indicate a time delay is
counting down. After the 15 minute delay the LED will de-
energize and a start -up sequence will initiate.
LOW REFRIGERANT PRESSURE SHUTDOWN
If the low pressure switch is open for more than 5
continuous seconds during the ice making cycle the ice
machine will shut off. The control board starts a 15 minutes
time delay and the HARVEST LED energizes to indicate
a time delay. After the 15 minute delay the LED will de-
energize and a start-up sequence will start.
POWER INTERRUPTION
If there is a power interruption during the ice making
cycle or if power is disconnected/reconnected the control
board starts a 15 minute time delay period. The SAFETY 2
LED light flashes to indicate a time delay period. After the
15 minute delay the LED will de-energize and a start-up
sequence will begin.
ROTATION SHUTOFF
During the ice making cycle if the rotation of the gear
motor is out of range for more than 5 seconds, the rotation
sensor will deactivate and stop the gear motor and
compressor. A 15 minute delay will begin and the SAFETY
1 LED and rotational LED will flash. When the delay period
ends the rotational LED and SAFETY 1 LED stop flashing
and the ice machine begins a start-up sequence. After 8
consecutive attempts to restart, the ice machine will remain
off and the SAFETY 1 LED will remain energized. The ice
machine will remain off until main power is disconnected
and reconnected. This will start a 15 minute delay period
after which the ice machine will initiate a start-up sequence.
ICE CHUTE SWITCH
When the ice chute switch opens during the ice making
cycle for 5 continuous seconds. All outputs are de-
energized for 8 minutes. After the 8 minute delay the ice
machine will go to startup sequence. The BIN SWITCH LED
will be flashing to indicate a time delay before startup. After
the 15 minute delay the yellow LED will turn off.
THERMISTOR FAILURE
If the microprocessor control board receives an open or
shorted cabinet thermistor signal, the following will happen:
1. A fault is displayed on the LCD screen
- Cabinet sensor open
Or
- Cabinet sensor shorted
2. The microprocessor will initiate a default sequence for
the refrigeration system - 12 minutes on, 3 minutes off.
3. The default cycle continues until the fault is corrected or
power is disconnected.
