as these LEDs are lit, the machine cannot be started and the source of the signal should be
determined and the condition has to be corrected to enable the system to start again.
If it is not obvious which input is causing the condition, simply disable the enabled inputs
on S1, one after the other. When the LED goes off, you have found the source of the Stop
input.
“START O/P”. This amber LED will light for about 1 second when a Start signal is
received, indicating that the board is sending start signals to upstream (unless disabled by
the front panel Feeder Enable switch) and downstream equipment.
“STOP O/P”. This red LED will light for about 1 second when a Stop signal is received,
indicating that the board is sending stop signals to upstream and downstream equipment.
The LED is connected to the pulse generator circuit and will only light up for one second,
even if the pulse circuit is bypassed by S2.
“RUN O/P”. This green LED is lit as long as the board is in a “Run” condition. It is also
duplicated in the Start button on the front panel. If it is lit, the board is activating the Run
relays for the base transport and conveyor motors, closes the Run contact for the feeder
and sends +12 VDC and ground to the downstream heaters. The lights will be
extinguished when a STOP signal is received, or the power to the board is removed.
Using these lights and understanding what activates them, it is fairly easy to determine the
source of any electrical problem in the machine. This, of course, assumes that the board
itself is functioning properly. If it is not, and the problem is something other than simply a
burned-out fuse, then the board should be replaced and returned to the factory for repair.
If the board itself is operating properly and all configuration switches are set as required
by the application, then the problem must be in one of the peripheral components, such as
the Run relays for the base and conveyor motors, the respective speed control units or the
motors themselves, or there could be a loose wire or bad contact.
