voltage drop.
17.6 .... Trouble Shooting - Machine Will Not Feed
Suction Valve Will Not Operate - Check the security of the 3 way
plug at the rear of the Control Box, and the valve connector
on the valve coil
Check the wiring to the valve connector, the 3 way plug &
socket and to terminals 12 & 13 at the control PCB inside
the Control Box.
Check the wiring between the feed ‘On’ / ‘Off’ switch on the
front panel and terminals 20 & 21 on the control PCB
Check the voltage at the valve with the feed switch ‘on’ (it
should be 4VDC). If the Voltage is incorrect, replace the
control PCB.
If the Voltage is correct, check the coil resistance (it should
be 10 Ohms). If it’s incorrect replace the coil. If the coil
resistance is correct, dismantle the valve (See Section 15)
and inspect the plunger assembly for failure or sticking.
If the valve is okay then replace the control PCB.
Machine feeds one sheet and fails to feed thereafter: -Check the
security of the 6 way connector at the rear of the Control
Box.
Check that the rotation sensor micro-switch (which is
located on the main clutch back plate), is operated by the
clutch stop collar when the clutch rotates
and when the
clutch stops.
Check the wiring to the micro-switch, the 6 way plug and
socket on the rear of the control box, and to terminals 9, 10,
11, on the control PCB.
