10.4 Electrical Troubleshooting
The electrical control circuit drawing is required for reference and diagnostics. A copy of the
electrical control circuit is in the electrical control cabinet and in the Supplementary Manual.
Close the guard doors, and make sure the
‘EMERGENCY STOP’
button is in the
OUT
position by
turning the knob
8
1
turn clockwise. Confirm that:
1. All lines into the machine, as listed on the electrical control nameplate in the control
panel, have the correct voltage.
2. The fuses on the disconnect switch are operating properly.
3. The disconnect switch is
ON
(
4
1
turn clockwise).
‘READY’
is displayed on the screen.
4. The PLC terminals (‘IN+’ and ‘IN-‘, ‘DC24+’, and ‘DC COM’) are all operating at 24 V DC.
5. MicroLogix 1200 programmable logic controller status LEDs (on left side) are illuminated
as follows:
‘POWER’
and
‘AUTO’
are
ON
.
‘FAULT’
and
‘FORCE’
are
OFF
.
If the ‘AUTO’ LED is
OFF
, use the disconnect switch to turn
OFF
the electrical power to the
machine, and then turn it back ON.
In the unlikely event that these LEDs are still illuminated improperly, and you do not have the
appropriate PLC interface, or training, contact WEXXAR's service department. Without the
appropriate equipment and training to correct this status, there is nothing else that you can do.
After completing the above confirmations:
1) Press the
‘RESET’
button once.
‘READY’
appears on the display and air pressure will now be
applied to the various machine
mechanism cylinders and they move to their respective
HOME
positions as follows:
2) From here, you can choose to go either into
CYCLE
mode or into
JOG
mode.
3) Press the
‘START’
button once. The feedbelts should start oscillating.
4) Check that the conveyor side-belts are tracking properly. They should be centered on the drive
pulley, properly tensioned, and in reasonably good condition.
WARNING!
THE ELECTRICAL CONTROL CABINET CONTAINS
MULTIPLE VOLTAGES. THE FOLLOWING WORK MUST
BE CARRIED OUT BY A QUALIFIED ELECTRICIAN, AND
APPROPRIATE SAFETY PRECAUTIONS MUST BE
FOLLOWED.
WARNING!
Actuating the ‘STOP’ or ‘EMERGENCY STOP’ buttons for this
procedure is not adequate.
