INTELLITEC CONTROLLER
Understanding the modes of operation and individual con-
trol settings will make servicing the control straightforward.
A.
COMPONENTS OF CONTROLLER
The IntelliTec control consists of three main components;
the control board (Figure 6-1), the membrane switch (Figure
6-2), and the display panel module (Figure 6-3). The
membrane switch is connected to the display panel module
via a 9-pin ribbon cable. The display panel module is
connected to the IntelliTec control board through a tele-
phone cord. The IntelliTec control board is connected to the
machine through an 8-pin connector, a 7-pin connector, and
a 6-pin connector.
The left side membrane switch (touchpad) controls the left
freezing cylinder and the hopper; the right side membrane
switch controls the right freezing cylinder. The IntelliTec
control boards are mounted in the same respect; the left
control board runs the left side and the right control board
runs the right side.
6.2
CONTACTORS
The compressor and drive motor contactors are mounted
inside the electrical box behind the right side panel. There
is one contactor for the compressor and a contactor for
each drive motor.
The IntelliTec control sends electronic signals to trigger the
contactors. Separate signals are used to control each drive
motor contactor and the compressor contactor. The signals
to the contactors are staggered, so the drive motor will
always start three seconds before the compressor. By
staggering the starting and stopping of the drive motor,
maximum starting torque is available and voltage spikes
are reduced.
