Your packaged Tube-Ice
®
machine is equipped with cutter and pump motor starters (CU and P) and
a transformer (if required) for the control circuit power. The control panel and transformer are
mounted on the machine front side (see Figure 1-1).
The control panel wiring schematic, FIGURE 6-3, illustrates these components as well as provisions
for auxiliary equipment which may be incorporated by the customer such as:
Fused Main power disconnect
(2CR) NO Highside “On” Auxiliary Contact
(T3) Conveyor “On” Timer
When adding a high side unit or motor starters for auxiliary equipment, be sure to incorporate the
overload protection as indicated between terminals #2-#12. This will assure that the machine will
shutdown when any auxiliary equipment fails.
Bin Level Control
. Included in the wiring schematic is provision for a bin thermostat or bin level
control (BT). The NC contact of your control should be wired between terminals #11-#14 and the
jumper wire removed as indicated. Installation in this manner will allow the machine to finish the
harvest period before shutdown. The machine will automatically restart when the bin thermostat or
bin control device is no longer in contact with the ice. To insure that the machine does not restart set
the “Clean/Off/Ice” toggle switch to the “Off” position.
Safety Switches
. The machine is not equipped with the following safeties and control switches,
however they can be wired into the control circuit.
•
Dual High/Low pressure switch (1PS) to stop the machine if the compressor suction pressure
goes too low (15-20 psi) or the compressor discharge pressure goes too high (225-250 psi).
Consult factory for detailed installation information.
