Solenoid interlock
AZM 170 AS
EN
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 170 AS. In the power to lock variant of the AZM 170 AS, the functio-
nal set of output bit 0 will cause the solenoid interlock to be locked. In the
power to unlock variant of the AZM 170 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 Coniguration of the safety monitor
Depending on the component used, the AZM 170 AS can be conigured
in the ASIMON coniguration software with the following safety monitors
(also refer to the ASIMON manual).
Dual-channel dependent with iltering
Suitable for: AZM 170 B ST-AS
The use of this safety monitor is especially advantageous on safety
guards, which bounce or vibrate against the end stop during the closing
operation.
• Optionally with start-up 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 enabled after expiration of the
stabilisation time and the synchronisation time must always be chosen
so that it is considerably longer than the stabilisation time.
Dual-channel conditionally dependent
Suitable for: AZM 170 BZ ST-AS
• Independent: In - 2
As long as the actuator remains inserted, the unlocked safety guard
can be closed back at any time; at that moment, 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 coniguration. To test these conditions, additio-
nal measures must be taken beyond the safety monitor .
Dual-channel dependent
Suitable for: AZM 170 B ST-AS
• Synchronisation time typically: 1.0 s;
for AZM 170 BZ ST-AS ininite (∞)
• Optionally with start-up test
• Optionally with local acknowledge
When the AZM 170 BZ ST-AS is used together with this safety-moni-
toring module for conducting the start-up test prior to every restart, the
safety guard must be opened.
The coniguration of the safety monitor must be tested and
conirmed by a qualiied 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 de-
scription) by means of the "Write parameter" instruction (with hexadeci-
mal value F). This (non-safe) diagnostic information from the relected
parameters or the answer to a "Write parameter instruction" can be
used by the user for diagnostic purposes or for the control programme.
