Safety in Maintenance and Repairs
Before starting any repairs or maintenance on the Pan Feeder System observe the following safety steps:
1. Isolate the whole of the system from the electricity supply by switching OFF the power isolator and
locking it.
2. Keep the key in the possession.
3. When making any repairs to the auger, be aware that it may be under some degree of tension. Avoid
touching the auger with the hands until you are sure that it is loose at all points. Use a suitable tool
to check the auger.
4. Do not reconnect the power supply until all work is completed and all guards are correctly refitted.
Problem
Checks
Corrective Action
1. Spinner control pan will
not shut system OFF.
a. Check to see if the feed has stopped the
paddle of the spinner motor and the
green light is OFF, but the feed line
motor still runs.
a. Replace the solid state relay.
b. Check to see if the feed has stopped the
paddle of the spinner motor and the
green light is ON, but the feed line motor
still runs.
b. Replace the PC board.
c. Check to see if feed reaches the spinner
motor, but the paddle continues to “drill”
through the feed.
c. Change the pulse settings to a lower pulse,
using the DIP switches on the PC board.
d. Check to see if the feed bridges over the
throat instead of falling into the pan.
d. Make sure nothing is blocking the throat
and that feed is dropping into the center of
the throat.
2. Spinner control pan will
not restart system when
feed is called for.
a. Check to see if the spinner motor in the
end control pan does not spin and the
yellow light is ON with a bright pulse
every 5-10 seconds.
a. Replace the spinner motor.
b. Check that the spinner motors, in a
system with a center house control pan,
does not spin and the yellow light is ON
with a bright pulse every 5-10 seconds.
b1. Make sure the voltage at the spinner motor in
the center house pans is between 17 and 24
volts, if center house pans are used.
b2. Make sure the field wiring is correct to
the center house control pans, if there is
no voltage.
b3. Use a heavier gauge wire, if the voltage
is very low.
c. Check to see if the spinner motor does
not spin and the yellow light is not ON.
c. Replace the PC board.
d. Check that the spinner motor spins, but
the feed line motor does not come ON
and the green light comes ON after a
10 seconds delay.
d. Replace the solid state relay.
