9.2.4 Checking the limit switch position

➠ Check the minimum and maximum width and ensure that the conveyor rails are parallel.

Settings:

Minimum width:49.7 mm

Maximum width, single conveyor:508.5 mm

Maximum width, dual conveyor:250.5 mm (When the fixed conveyor rail is extended)

Maximum width, dual conveyor:216.5 mm (Standard)

Legend

– 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.

9.2.4.1 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. 9.2 - 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. 9.2 - 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.

9.2.5 Width adjustment unit (Driver)

9.2.5.1 Setting the BERO on the driver

The BERO (3) (see Fig. 9.2 - 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.

Legend to Fig. 9.2 - 9:

Setting Bero and actuator for transport rail position: 9

➠ 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.
