Check that the current setting on the overload has been properly set for the incoming voltage.
Refer to the nameplate on the motor for the proper setting. At 208 volts the setting will be
approximately 16 amps while at 480 the setting will be approximately 10 amps.
3.
Press the blue motor
reset pushbutton.
4.
Test the alarm by pulling out the red pushbutton to trip the overload. The display should read
MOTOR STARTER.
CHECK PHOTO EYE
1
.
This alarm indicates that the photo eye has seen trash continuously for more than 30 minutes.
Clean the photo eye and the reflector.
2.
Check the alignment of the photo eye. The photo electric is polarized to prevent false readings
on white boxes. There are three lights on the top of the unit. The green light indicates that
there is power to the unit. The yellow light indicates that the output is turned on and the red
light indicates that the unit is properly aligned. There is also a light/dark switch on the top of
the unit. For the Chute Source compactor circuit
, the switch should be in the “LO” position
.
When the unit is properly aligned all three lights should be on. When trash is blocking the
photo’s line of sight,
only the yellow should be on.
RAM DOES NOT COMPLETELY RETURN TO THE RETRACTED POSITION.
1.
In Manual control - extend and retract the ram. Watch the pressure readings while the ram is
retracting. In normal operation the pressure will read between 350 and 550 PSI. Any reading
higher than that will indicate that some refuse has gotten behind the ram and the system is
compacting in both directions. The pressure reading will normally jump at the end of the
stroke. This is because the ram will bottom out against the back of the compactor. Ignore the
final pressure reading. The reading of interest is the reading while the ram is retracting. If
enough trash has accumulated behind the ram the system will see high pressure during the
retract cycle sooner than it should. This will shorten the retract position and probably result in
a COMPACTOR FULL alarm on the next forward movement.
