The reversing drum switch is similar to
the manual start switch, but has the
added advantage of being able to
reverse the motor.
It is standard
equipment on most HYTROL portable
model conveyors,
and is normally
mounted near the conveyor drive. The
reversing drum switch is considered as
a single point control, but may be
extended through the use of a remote
control rod (optional item), allowing the
operator to control the conveyor from
either end. NOTE: This switch does not
provide for motor overload protection.
1. Customer is to ground switch and motor
at points shown on diagram.
2. Consult national electrical code for wire
size to be used for connections between
motor and switch.
3. This method provides no overload
protection for motor.

• Wiring Diagram — Safety Disconnect Switch or
Manual Start Switch
The manual start switch is a simple “ON-OFF” switch that directly
controls the motor power. It is suitable for a large number of
conveyor applications not requiring a reversible operation. The
manual start switch is a single point control and is normally mounted
at or near the drive. NOTE: This switch does not provide: motor
overload protection.

• Wiring Diagram — Push Button Station
Remote push-button stations, designed for magnetic
starters, are used to control the starter coils.
Starters may be controlled by single or multiple
push-button stations.
Hytrol’s standard control
voltage through the push-button station is 115 volt,
single phase.

• Wiring Diagram — Reversing Three Phase Starter
The reversing magnetic starter directly controls the
current to the motor by actually closing the required set of
contacts to cause motor rotation in the desired direction
(Forward/Reverse), and provides a remote means of
conveyor directional control.
Remote pushbutton
stations, designed for magnetic starters, are used to
control the starter coils. Starters may be controlled by
single or multiple pushbutton stations. Magnetic starters
also provide the added feature of overload protection for
the motor.
