A Power to lock
P Device supplied through auxiliary voltage
MZM 100-B1.1 actuator
Only if the information described in this operating instructions
manual are realised correctly, the safety function and
therefore the compliance with the Machinery Directive is
maintained.
2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Purpose
The safety switchgears are classified according to
ISO 14119 as type 4 interlocking devices.
The MZM 100 AS is designed for application with AS-Interface Safety
at Work and is used for monitoring the position of movable separating
safety guards. A door detection sensor monitors the closed condition of
the safety guard.
The optional variable latching force is activated by the detection of the
actuator when the safety guard is closed. The latching force exercised
by the permanent magnet keeps the safety guard closed, also in de-
energised condition (approx. 15 N).
The latching force F of the MZM 100 AS solenoid interlock is
permanently measured and checked.
A safe magnetic force monitoring detects when the latching force
drops below a defined latching force. In this way, soiling of the solenoid
interlock can be detected. If the latching force drops below 500 N, the
AS-i Safety codes are not enabled.
The different variants can be used as safety switch with interlocking
function either as solenoid interlock.
If the risk analysis indicates the use of a monitored interlock
then a variant with the monitored interlock is to be used,
labelled with the symbol.
The actuator monitoring variant (B) is a safety switch with an
interlock function for process protection.
The safety function of MZM 100 variant "Solenoid interlock monitored"
consists of safely monitoring a magnetic interlocking force for a safety
guard, safely switching off the code transmission when the magnetic
force drops below a defined magnetic force and maintaining the
safe switched off condition for as long as the safety guard is open or
unlocked.
The safety function of MZM 100 B variant "Actuator monitored" consists
in safely switching off the code transmission when the safety guard is
opened and maintaining the safe switched off condition for as long as
the safety guard is open.
Interlocks with power to lock principle may only be used in
special cases after a thorough evaluation of the accident
risk, since the safety guard can be opened immediately on
failure of the power supply or upon activation of the main
switch.
An AS-Interface Safety at Work component functions on the basis of
an individual code generator (8 x 4 bit). This safety code is cyclically
transmitted over the AS-i network and monitored by a safety monitor.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.

3.1 General mounting instructions
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.
The safety switchgear must be used as end stop.
Any mounting position. The system must only be operated with an
angle of ≤ 2° between the solenoid interlock and the actuator.
For fitting the MZM 100 AS and the actuator, two mounting holes for M6
screws with washers (washers included in delivery) are provided.
After fitting, the mounting holes can be sealed by means of the supplied
plugs. The plugs serve as a means of sealing the assembly openings
and are also suitable to prevent against tampering with the screw
connection. If necessary, these plugs can be removed from the actuator
by exercising pressure on the top side (in case of fitting with connector
downwards) or on the right-hand side on the plugs of the anchor plate.
Minimum distance between two devices: 100 mm
At an ambient temperature of ≥ 50 °C, the safety component
must be fitted so that it is protected against unintentional
contact with persons.
The safety component must be operated in the operating
direction of the latching force (refer to image).

4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
The MZM 100 AS safety switchgear and the interlocking solenoid are
supplied from the auxiliary energy. The AS-Interface mode is supplied
from AS-i. Both voltage supplies of the safety switchgear must be
equipped with a protection against permanent overvoltage. To that
effect, stabilised PELV supply units must be used.
The connection to the AS-Interface system is realised through an M12
connector. The M12 connector is A-coded. The wiring configuration of
the M12 connector is defined as follows (to DIN EN 62026-2):
AUX +(P)

AS-Interface -
AS-Interface + AUX -(P)
5. Functions and configuration
5.1 Mode of operation of the safety outputs
MZM 100 ST-AS …
The safety outputs of the AS-i safety monitor are enabled, when the
following conditions are met:
• the actuator has been detected
• the interlock is locked, the magnetic force is > 500 N
MZM 100 B ST-AS …
The safety outputs of the AS-i safety monitor are enabled, when the
following conditions are met:
• the actuator has been detected, the latching force is active
• locking with magnetic force > 500 N possible
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. To lock the interlock, output bit DO 0 of the MZM 100 AS must be
set to "1" by the control.
5.3 Description of the latching and the latching force adjustment
The latching force exercised by the permanent magnet (M) keeps the
safety guard closed, also in de-energised condition (approx. 15 N). The
electrical latching is activated by the detection of the actuator when the
safety guard is closed.
The latching force (RE) can be set in 8 steps through the control system
using the output bits DO 1 … DO 3 of the addressed AS-i slave
MZM 100 AS.
DO 3 2 1 Latching force RE Latching force REM
0 0 0 approx. 30 N approx. 45 N
0 0 1 approx. 40 N approx. 55 N
0 1 0 approx. 50 N approx. 65 N
0 1 1 approx. 60 N approx. 75 N
1 0 0 approx. 70 N approx. 85 N
1 0 1 approx. 80 N approx. 95 N
1 1 0 approx. 90 N approx. 105 N
1 1 1 approx. 100 N approx. 115 N
The actual latching forces may deviate from the specified
values owing to the different influences (e.g. angled position
of actuator, contamination or damage to metal surface, etc.).
When the guard system is opened for the first time from the
locked status, higher latching forces may be experienced on
account of residual magnetism.
5.4 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.
5.5 Configuration of the safety monitor
The MZM 100 AS can be configured in the ASIMON configuration
software with the following monitoring devices (also refer to the
ASIMON manual). (also refer to the ASIMON manual)
Double channel dependent
• Synchronisation time: 0.1 s
• Optionally with startup test
• Optional with local acknowledge
The configuration of the safety monitor must be tested and
confirmed by a qualified and authorised safety expert/safety
engineer.

5.6 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
thiseffect, 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.
5.7 Violent separation of solenoid interlock and actuator
(only in connection with "Solenoid interlock monitored")
The solenoid interlock has a latching force F of 500 N.
When the actuator and the interlock are separated in an
unauthorised and violent way, the safety guard is opened
and the safety outputs are switched off within 150 ms.
This is signalled through the yellow and red LED blinking
alternatively.
To bring the system back to an operational condition,
proceed in the following way:
• Close the safety guard
• Switch off the solenoid control once and then switch it back
on (the yellow and red LED now flash simultaneously)
• Now wait for the 10-minutes tampering protection time to
expire with the safety guard closed, until the LED’s go out
• Switch the solenoid control once more off and on
The device now is ready for operation again.
6. Diagnostic
6.1 LED indications
The LED's have the following meaning (to DIN EN 62026-2):
LED green-red
(AS-i Duo LED):
AS-Interface supply voltage/
AS-Interface communication error or
slave address = 0 or periphery error
Red LED: Internal device error
Yellow LED: Device status
6.2 Error
Errors, which no longer guarantee the safe functioning of the
MZM 100 AS electromagnetic interlock, cause the safety outputs to be
switched off and are signaled through a flashing pattern of the red LED.
(see table 2)
After fault rectification, the error message can be reset by opening and
closing the relevant guard door. The safety outputs of the safety monitor
can be switched back on, thus enabling the machine.
6.3 Locking of the solenoid interlock blocked
When the interlocking function of the solenoid interlock is blocked and
no latching force of at least 500 N could be generated, the MZM 100 AS
will emit a warning message. This is signaled by the alternating red/green
flashing of the AS-i duo LED on the device.
Possible causes for the blocked interlocking function:
• Solenoid soiled
• Guard incorrectly closed
• Too large a misalignement between the
solenoid interlock and the actuator
6.4 Diagnostic information

6.5 Diagnostic signal periphery error
All warnings or error messages of the MZM 100 AS are transmitted as
"periphery error" to the control system through the AS-i master.
The signal "periphery error" is a centralised alarm signal from warnings
or error messages. The periphery error (FID input of the AS-i chip)
is controlled together with parameter port P3. A "periphery error" is
signaled by the alternating red and green flashing of the AS-i duo LED
on the device.
6.6 Read-out of the parameter port
The parameter port P0 to P3 of an AS-i slave 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.
