– Limit switches on the input conveyor: There are 5 limit switches below the conveyor rails near
the input conveyor. The limit switches are intended to prevent the conveyor rails moving to-
gether or against the basic conveyor frame.
– Limit switches on the output conveyor: There are 2 limit switches for the driver near the output
conveyor. They serve to protect the traveling range and initialize (right side) the driver for the
width adjustment.
10.2.4.1 Adjusting the limit switch for initialize the driver
Please Note: This is only necessary in case of replacement of the switch or other mal functions
in width adjustment reference run.
Fig. 10.2 - 8 Limit /initialize switch
➠ Move the driver for the width adjustment by hand (via the toothed belt) to the conveyor rail.
➠ Loosen both screws of the limit switch (arrow in Fig. 10.2 - 8)
➠ Move the limit switch in the slot towards the driver and make sure, that the limit switch is safely
switched on.
➠ Check the status of the associated LED on the conveyor control (H41 ini TSP 301) .
➠ Fit the limit switch in this position.
➠ Calibrate the conveyor width via the SITEST program.

10.2.5 Width adjustment unit (Driver)
10.2.5.1 Setting the BERO on the driver
The BERO (3) (see Fig. 10.2 - 9) provides a signal for controlling the pneumatic valve of the driver.
Once the switching point ’conveyor rail reached’ is reached, the pneumatic valve engages the
conveyor rail.

Setting Bero and actuator for transport rail position: 10
➠ When the BERO (4) is installed, it must not protude the driver.
➠ The switching point is set via the actuator on the conveyor rail
➠ Move the driver under the conveyor rail, then loosen the actuator using the screw.
➠ Place the driver at the final dimension of 2/10 mm, press the actuator onto the final dimension
and fix with the screw.
➠ Actuators on all conveyor rails have to be checked and maybe adjusted.
➠ Start SITEST and Calibrate transport.

➠ This setting must be repeated for all the conveyor rails.
10.2.5.2 Setting the ’pneumatic cylinder BERO’ on the driver
The BERO (3) (see Fig. 10.2 - 9) on the driver cylinder is designed to switch when the pin of the
driver is extended by the pneumatic cylinder so that the conveyor rail is engaged. This signal en-
ables the width adjustment motor.
Procedure: 10
Please Note:
The BERO on the pneumatic cylinder is set in the engaged state (but not in the free space!).
➠ Start SITEST
➠ Set any conveyor width. This moves the drivers directly under the conveyor rail.
➠ Start the I/O menu.
➠ Activate the pneumatic cylinder.
➠ Set the BERO on the pneumatic cylinder so that the LED (H35/H36/H37 TSP 301) lights up in
the engaged state (see Fig. 10.2 - 9).
