The following is an explanation of the control panel controls:
1) BEATER MOTOR STARTER - activates the beater/auger
drive motor. In the "BEATER" mode, the starter is energized by
the front switch pad. In the "AUTO" mode, the starter is activated
by either the proximity switch or timer.
2) COMPRESSOR CONTACTOR - activates the refrigeration
compressor. When the unit is in the "AUTO" mode, the compressor
contactor can be energized by the electronic H.O.M., timer, or
"TEV" thermostat. In the "ENERGY CONS." mode, the contactor
will be energized by the electronic board.
3) The OVERLOAD PROTECTOR senses the current supplied
to the beater motor and will stop the entire machine in the event
of an overload. This device also houses the overload reset
mechanism.
4) The main TRANSFORMER steps down the line voltage (115
Volts) to 24 Volts for the control circuit.
5) ELECTRONIC BOARD - controls all the functions of the
machine.
- Temperature of the product in hopper.
- Consistency of the product.
- Timer.
- In stand-by controls temperature of the product in hopper and
cylinder.
- Controls and or energizes all the information or messages
displayed on the monitor.
6) FUSE - protects 115 voltage line.
7) The CURRENT TRANSFORMER monitors beater motor
current for the electronic H.O.M.
8) TRANSFORMER - Steps down the 24 volt line to 11 volts for
the electronic board.
9) The 24 volt TERMINAL BLOCK serves as the inter-connection
point for all 24 volt controlling circuit components.
F) OTHER CONTROLS
1) Refrigeration SOLENOID VALVES are located behind the left
side panel. These valves are normally closed and when energized
by the electronic board, direct refrigerant flow to either the
freezing cylinder or mix tank. The mix tank solenoid is identified
as "EVV" and the cylinder solenoid as "EVC".
2) The HIGH PRESSURE CUT-OUT is located on the right side
of the freezer and is tied into discharge or high side line near the
compressor. In the event of high pressure situation, it will shut
down the compressor. Reset is automatic when the high pressure
subsides. Common causes for cut-out or shut down arerestricted
air flow on air cooled models, unusually high ambient (room)
temperatures, and restricted or excessively hot water flow on
water cooled models.
