REPLACING
SAFETY AND
PROXIMITY
SWITCHES
Three safety switches are included in CSC cutters: a keyed
safety switch on the knife guard, and a proximity switch on
each cutter bushing. A failure in any of these switches will pre-
vent the cutter from running.
●
Safety Switch
If you suspect a problem with the keyed safety switch on
the knife guard, check for loose or damaged wires. Replace
the switch if wires appear to be undamaged.
●
Proximity Switches
The proximity switches on the cutter bushings have LEDs
that light when the bushing is sensed. If an LED does not
light when both bushings are in place:
Check for loose or damaged wires.
Remove the cutter bushing and make sure the prox-
imity switch is properly positioned, i.e. 0.010 inches
from the bushing surface.
Remove the proximity switch by loosening the set
screw. Test it by bringing some object close to the
sensor when the power is turned on. If the LED does
not light, replace the proximity switch.
The servo amplifier is equipped with a digital readout that can
be seen through the viewing window on the electrical enclo-
sure. This display shows amplifier status and error messages.
Refer to the supplier's documentation included with this User
Guide.
NOTE: Make sure you look for servo amplifier messages
before you shut off the power, because fault
message will be lost.
