The PFlow Industries, Inc. D series Vertical
Reciprocating Conveyor (VRC) is equipped
with a Motor Overload Sensor (MOL). The MOL
is prewired and located inside the electrical
control panel. See Figure 14-1.
The MOL monitors the motor amp draw and
provides enhanced over current protection of
the lift motor. The MOL must be adjusted to the
maximum “expected” current draw. If the motor
current rises above the MOL set point, the MOL
will trip. Tripping can be caused by a circuit
malfunction, overloading the capacity of the lift,
or an overhanging load trapped between floors.
1. Review the electrical drawing J#-0050.
2. Locate the hydraulic pump motor information
on page 1 or page 2. The F.L.A. value is listed
after the HP value. See Figure 14-2. The
information may also be found on the VRC
Specification for this job.
1. Turn the trip point dial to match the F.L.A. value.
2. Place the maximum product load on the carriage.
