Timing of detection
• The communication with the puncher unit is
disrupted.
• The checksum for the puncher controller PCB
has an error when the power is turned on.
• A Start signal has been received although 24
VDC is not supplied from the finisher.
• The puncher does not return to the punch
motor home position sensor when the punch
motor has been driven for 250 msec.
• No clock is detected from the punch motor
clock sensor for 60 msec when the punch
motor has been driven.
• The light-receiving voltage is 2.5 V or less when
the light-emitting voltage is set to 4.4 V while
sensor output auto adjustment is under way.
• The light-receiving voltage is 2.5 V or more
when the light-emitting voltage is set to 0 while
sensor output auto adjustment is under way.
• The light-emitting voltage is set to 4.4 V or more
after sensor output auto adjustment.
• The light-receiving voltage is 2.5 V or less
when the light-emitting voltage is set to 4.4
V while sensor output auto adjustment is un-
der way.
• The light-receiving voltage is 2.5 V or more
when the light-emitting voltage is set to 0 V while
sensor output auto adjustment is under way.
• The light-emitting voltage is 4.4 V or more
after sensor output auto adjustment.
• The puncher does not leave the horizontal regis-
tration home position sensor when the horizontal
registration motor has been driven for 1000msec.
• The puncher does not return to the horizontal
registration home position sensor when the
horizontal registration motor has been driven
for 1000 msec.
