Section 16 CONTROL SYSTEM (FRN)
The following sections should be used in conjunction with the
troubleshooting section in the operators guide.
16.2..... Trouble Shooting -
Machine Will Not Run
System Switch does not latch Check that the guards and feed
bed are correctly fitted and that both fuses are intact and
firmly installed.
Lower the control panel (see section 16.1), and check the
security of the two blue wires to terminals 22 and 23 and the
two white wires to terminals 18 and 19.
Check the continuity through white wires to terminals 18
and 19 (remove wires from PCB first). If there is no
continuity, trace the fault to a defective switch connection
or a defective switch.
If the PCB 'clicks' when a guard is opened or closed,
replace the system switch. If there is no audible 'click' then
replace the PCB.
System Switch Latches Is the machine jammed ?. It should
rotate freely by using the handwheel.
To minimise starting loads, ensure that the 'Feed' switch is
‘Off’ and that the main clutch is not still engaged. This can
happen if the machine was switched off during a numbering
cycle before the heads had stopped. Turn the machine by
hand to position the heads in their starting position.
Check the mains voltage to the motor and the connections
to the capacitor.
If all else fails, replace the motor.
16.3..... Trouble Shooting -
Machine Will Not Feed
Friction Feed Tyres do not rotate Check the wiring between the
feed on / off switch on the side-cover and terminals 20 & 21
on the PCB and check the wiring between the feed clutch
and terminals 12 & 13 on the PCB.
