ward slow down delay.
The forward slow-down sensor
may not be working.
► Check U1-3 and the sensor.
The tray clamp may be moving

during the index cycle, blocking
the path of a new tray.
► Manually remove the tray
from the “tray home” position,
then press the Reset button.
There may be a problem with the
“stop at end” or “ready” sensor.
► Check U1-4 and the sensor.

and slipping.
► Clean the conveyor belts with
alcohol.
There may be an obstruction on
the conveyor.

The tray clamp cylinder may not
have retracted properly. When
the tray returns, the tray clamp

inder.
► Check the valve block for the
cylinder.
► Check the cylinder itself.
