The following procedure is used to set the drum encoder and the location of the Tail
grippers at the end of the slot. This will enable bringing the drum under the actuator
pins when performing pre - load.
Procedure
Open the rear cover of the Lotem
Slide tail grippers all the way down the slot until they are at the end opposite the
head grippers.
Open from the H/W menu the drum system / drum motor, double click on the drum motor.
Place the tail grippers under the Unloading upper grippers actuators pins. Make sure
that the drum power is turned off.
Hold the drum in position, slowly activate the upper grippers actuators valve from the
Manifold.
Rotate the drum gently until the activator pins are in the middle of the tail gripper
groove. At that point record the reading of the drum current position. (It should be
around "204")
Recording the final value to the registry – Go to the Lotem registry /…./Lotem
800 V/ I/O objects / Loading System/ Drum. From the Drum list on the right side
,double click on the " Init tail Gripper Pos". Change the current parameter with
the new one .
Testing
Load plate when the rear cover is open. This will rotate the drum and bring the tail
grippers to the position loaded for the new plate size.
During the pre – load process check that the actuators pins are in the middle of
the tail grippers groove.
Check that the tail grippers garb the edge of the plate between 2.5 mm to 4 mm.
