The PFlow Industries, Inc. Vertical
Reciprocating Conveyor (VRC) is equipped
with an Overcurrent Sensor (OCS). The OCS
is pre wired and located inside the electrical
control panel. See Figure 21-1.
The OCS monitors the motor amp draw and
provides enhanced over current protection of
the lift motor. The OCS must be adjusted to the
maximum “expected” current draw. If the motor
current rises above the OCS set point, the OCS
will trip. Tripping can be caused by a circuit
malfunction, overloading the capacity of the lift,
or an overhanging load trapped between floors.
1. Turn the trip point dial to its lowest position.
2. Place the maximum product load on the carriage.
