ELECTRICAL CONTROLS AND OPERATION

REMOTE LIMIT SWITCH
(See Figure 7)
Note: Your machine will not run continuously in the forward direction unless the
REMOTE LIMIT SWITCH is plugged into the machine. The Remote Limit Switch
is used for panel length control. It is designed to attach to the right side of the
optional RUN OUT TABLES available for your machine. Plug the female end of a
3-wire 14-gage extension cord into the limit switch, and the male end into the female
Limit Switch Plug located at the bottom of the Control Panel Assembly. The length
of the panel you intend to run determines length of the extension cord needed. Run
out a panel to the desired length and stop the machine. Slide the Remote Limit
Switch onto the bottom let of the angle on the right side of the run out table so that
the ARM of the switch is against the end of the panel. Pull the limit switch back
toward the shear until you hear a click in the Limit Switch Head and secure the limit
switch at this location. Cut and remove the set up panel from the table. Push the
start button and run the next panel allowing the limit switch to stop the machine.
Measure this second panel before cutting to determine if it stopped in the correct
position and make the necessary adjustment to the limit switch to obtain the desired
length. Repeat as necessary.
FUSES
(Figure 8)
All machines, gas or electric powered, have a 10-amp time delay fuse inside the Electrical
Control Panel Assembly. This fuse protects the electrical components. If the fuse is blown,
you will lose all functions of the machine except Motor Start. To replace this fuse: Loosen
all 4 cover screws and open the front panel of the Control Box. Locate the automotive style in-
line fuse near the bottom right hand corner. It is a spring loaded twist lock holder. Push
together and turn to open. Check the fuse with a continuity tester. If it is bad, replace with a
new fuse and re-connect spring loaded holder.
ELECTRIC MOTOR MACHINES
(Figure 9)
Electric motor machines have an additional 10-amp time delay fuse protecting the logic circuit
of the Contactor Box. This fuse holder is mounted in the side or top cover of the contactor box
located approximately mid machine on the right side. Access can be gained by removing the
center left side cover. This is a panel mounted, spring loaded fuse holder. To replace this
fuse: Push in on the cap and turn counterclockwise to release fuse. Check fuse with a
continuity tester. If the fuse is bad replace with a new fuse. To re-install, insert fuse into cap.
Install fuse and cap assembly into receptacle, push down and turn clockwise to lock in place.
