5.  Functions and configuration

5.1  Mode of operation of the safety outputs

AZM 161 Z ST-AS

The safety outputs of the AS-i safety monitor are enabled, when the 

following conditions are met:

• the actuator is inserted

• the solenoid interlock is locked

AZM 161 B ST-AS

The safety outputs of the AS-i safety monitor are enabled, when the 

following conditions are met:

• the actuator is inserted

AZM 161 BZ ST-AS

The safety outputs of the AS-i safety monitor are only activated, when 

both AS-i half-codes are enabled.

Half-code 1 (AS-i SaW bit 0,1) is enabled, when:

•  the actuator is inserted

The solenoid interlock now can be locked.

Half-code 2 (AS-i SaW bit 2,3) is enabled, when:

• the solenoid interlock is additionally locked.

5.2  Magnet control

The control system with the AS-Interface Master can lock and unlock 

the solenoid interlock through the output bit 0 of the addressed AS-i 

slave AZM 161 AS. In the power to lock variant of the AZM 161 AS, 

the functional set of output bit 0 will cause the solenoid interlock to be 

locked. In the power to unlock variant of the AZM 161 AS, the functional 

set of output bit 0 will cause the solenoid interlock to be unlocked.

5.3  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.

5.4  Configuration of the safety monitor

Depending on the component used, the AZM 161 AS can be configured 

in the ASIMON configuration software with the following monitoring 

devices (also refer to the ASIMON manual). 

Double channel dependent with filtering

Suitable for: AZM 161 B ST-AS

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

•  Stabilisation time typically 0.5 up to 1.0 s

•  Synchronisation time typically 5.0 up to 10 s

The safety-monitoring module is only released after expiration of the 

stabilising time; the synchronization time always must exceed the 

stabilising time.

Double channel conditionally dependent

Suitable for: AZM 161 BZ ST-AS

• Independent: In - 1

As long as the actuator remains inserted, the safety guard can be 

relocked at any time, in which case the safety outputs are reactivated. 

The safety guard must not be opened.

The redundancy and the "Safety guard closed" signal are not 

tested in this configuration. To test these conditions, additio-

nal measures must be taken beyond the safety monitor .

Double channel dependent

Suitable for: AZM 161 Z ST-AS, AZM 161 B ST-AS, AZM 161 BZ ST-AS

•  Synchronisation time typically: 0.1 s;  

for AZM 161 BZ ST-AS infinite (∞)

•  Optionally with startup test

•  Optional with local acknowledge

When the AZM 161 BZ ST-AS is used together with this monitoring 

device for conducting the start-up test prior to every restart, the safety 

guard must be opened.

The configuration of the safety monitor must be tested and 

confirmed by a qualified and authorised safety expert/safety 

engineer.

5.5  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.

5.6  Read-out of the parameter port

The parameter port P0 to P3 of a solenoid interlock can be read 

out through the control interface of the AS-i master (see component 

description) by means of the "Write parameter" instruction (with 

hexadecimal value F). This non-safe diagnostic information from the 

reflected parameters or the answer to a "Write parameter instruction" can 

be used by the user for diagnostic purposes or for the control programme.

Locking/unlocking of the

Locking/unlocking of 
the solenoid interlock 
not blocked

Error message "locking/unlocking of the solenoid interlock blocked"

This error is transmitted, when the solenoid interlock no longer can be 

correctly locked or unlocked. The causes for this error can be: the safet 

yguard is not correctly closed, the actuator is deformed, the manual 

release is not correctly reset or the auxiliary voltage is missing. This 

error is transmitted as "periphery error" to the control system through 

the AS-i Master. A "periphery error" is shown on the AS-i device by the 

alternating red/green flashing of the AS-i Duo LED.
