ELECTRICAL CONTROLS AND OPERATION
POWER CORD REQUIREMENTS
For machines equipped with a QCPP-E it is very important to follow the power cord
requirement prescribed by the motor and electrical control manufacturers to maintain their
respective warranties. Make sure the cord you are using is marked properly. Do not assume
that because an extension cord looks heavy enough that it is the right gauge.
Use of the
wrong gauge extension cord will void the warranty on motor and electrical controls.
GENERATOR USE FOR ELECTRIC MOTOR MACHINES
If a generator will be used to power the machine it must be large enough to handle the amp
draw requirements of the motor. Contact your local generator supplier for proper sizing and
refer to the specification plate on the electric motor.
Use of an improperly sized generator
will cause a low voltage situation of the electric motor and controls which will void the
warranty.
MANUAL CONTROL PANEL OPERATION:
(Figure 1)
A. FORWARD-REVERSE Switch
This selector switch controls the direction of movement of the material through the
machine. Select forward to feed material and run panel through the machine.
NOTE: For operator safety, your machine will not run continuously in reverse.
B. JOG-RUN Switch
This selector switch allows you to run the machine continuously, or jog material
through the machine. Select JOG to load coil into machine and to move material
through the machine in small increments until it clears the shear dies. Select run
after material has cleared the shear, and you are ready to run panel.
NOTE: The LENGTH CONTROL LIMIT SWITCH must be plugged in to the
Limit Switch Plug at the bottom of the Manual Control Box Assembly to run
continuously.
C. START FEED (Green button at Entry and Exit End)
This button is used to activate the drive system of the machine. (Jog only unless limit
switch is plugged in)
D. STOP FEED (Red button at Entry and Exit End)
This button acts as an emergency stop for the drive system when using the Length
Control Limit Switch.
Pressing either the entry or exit button will stop the drive
system of the machine in case of an emergency.
E. SHEAR DOWN (Green button)
Pressing this button once will cycle the shear to the bottom of its stroke and return it
back to the top or home position. This is one shear cycle
F. SHEAR UP (Red button)
Pressing this button during the down cycle of the shear will immediately send it back
to the top or home position.
G. EMERGENCY STOP-POWER ON (Raised Red Mushroom button)
