The roller lever can be repositioned over 360° on the toothed shaft in
10° steps. Unscrew the hexagonal screw approx. 4 mm, reposition the
lever in the desired position and retighten the screw
Length-adjustable lever (7H-2138)
To adjust the length of the lever, unscrew the fixing screw of the lever

4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition
The connection to the AS-Interface system is realised through an M12
connector or an AS-i flat cable clamp The wiring configuration of the
M12 connector is defined as follows (to EN 50295):

5. Functions and configuration
5.1 Programming the slave address
The slave address is programmed through the M12 connector Any
address from 1 to 31 can be set by means of the AS-i bus master or a
hand-held programming device
5.2 Configuration of the safety monitor
The safety switch can be configured in the ASIMON configuration
software with the following monitoring devices (refer to ASIMON
manual):
Double channel dependent
• Optionally with startup test
• Synchronisation time typically 05 - 20 s
Double channel dependent with filtering
The use of this monitoring device is especially advantageous on safety
guards where bounce or vibration against the mechanical stop upon
closing is a problem
• Optionally with startup test
• Stabilising time typically: 05 10 s
• Synchronisation time typically 50 - 100 s
The safety-monitoring module is only released after expiration of the
stabilising time; the synchronization time always must exceed the
stabilising time
The configuration of the safety monitor must be tested and
confirmed by a qualified and authorised safety expert/safety
engineer
5.3 Status signal "safety release"
The "safety release" status signal from a Safety at Work slave can be
cyclically queried by the control system through the AS-i master To
that effect, the 4 input bits with the varying SaW code of a Safety at
Work slave are evaluated through an OR operation with 4 inputs in the
control system
