6. Electrical Controls
Your low side Tube-Ice

machine is equipped with a dry contact (3CR) for a compressor motor
starter and a transformer (if required) for the control circuit power. The control panel and
transformer are mounted on the machine front side (see Figures 1-1 or 1-8).
The control panel wiring schematic, Figure 6-3, illustrates these components as well as provisions
for auxiliary equipment that may be incorporated by the customer such as:
(FU1) Main power disconnect
(5M) Conveyor motor starter and overload (5MOL)
(C-SOL) Suction regulating valve
When adding motor starters for auxiliary equipment, be sure to incorporate the overload protection
as indicated between terminals #12 - #13 and remove the jumper wire. 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 level control (BLC). The
NC contract of your control should be wired between terminals #8-#9 and the jumper wire removed
as indicated. Installation in this manner will allow the machine to finish the harvest period before
shutdown. However, the machine will still need to be manually started to resume production.
Safety Switches . The machine is not equipped with the following safeties and control switches;
however, they can be wired into the control circuit. Refer to the wiring schematic Figure 6-3 for
their circuitry.

High/Low dual pressure switch (1PS) to stop the machine if the compressor suction pressure
goes too low (15-20 psig) or the compressor discharge pressure goes too high (225-250 psig).
See “High/Low Pressure Switch”.
