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.
Additional information regarding the special versions can be
found on the enclosed form.
2.3 Purpose
The AZM 200 with non-contact electronic safety sensors is designed for
application in safety circuits and is used for monitoring the position of
movable safety guards.
The AZM 200D is a safety switch with additional interlocking
function.
The safety function consists of safely switching off the safety outputs
when the safety guard is unlocked (PL d / control category 3) or opened
(PL e / control category 4) and maintaining the safe switched off
condition of the safety outputs for as long as the safety guard is open.
➁
Power to unlock
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.
LED functions
The safety switch signals the operational state as well as errors through
three coloured LED’s installed at the front side of the device.

3. Mounting
3.1 General mounting instructions
For fitting the safety switch and the actuator, two mounting holes for M6
screws with washers (washers included in delivery) are provided. The
safety switch must not be used as end stop. Any mounting position.
The mounting position however must be chosen so that the ingress of
dirt and soiling in the used opening is avoided. The unused actuator
opening must be sealed by means of the dust-proof flap (included in
delivery).
Please observe the remarks of the standards EN ISO 12100,
EN 953 and EN 1088.
The constructor must provide for the necessary strain relief
of the connections.
Mounting of the actuators and the safety switches
Refer to the mounting instructions manual for the corresponding
actuator.

For the machine set-up, the safety switch can be unlocked in deenergised condition. After opening of the plastic flap "A" (refer to image
"Dimensions"), the triangular key must be turned clockwise to bring
the blocking bolt in unlocking condition. The normal locking function is
only restored after the triangular key has been returned to its original
position. Caution: do not turn beyond the latching point! After being
put into operation, the manual release must be secured by closing the
plastic flap "A" and affixing the seal, which is included in delivery.

4. Rear side 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 power supply of the safety switch must provide protection against
permanent overvoltage. To that effect, stabilised PELV supply units
must be used. The safety outputs can be directly integrated in the
safety circuit of the control system. For applications up to PL e /
control category 4 to EN ISO 13849-1, the safety outputs Y1 and
Y2 of the safety switch or safety switches must be connected to a
safety-monitoring module of the same control category (refer to wiring
examples). The antivalent switching safety outputs Y3 and Y4 are
suitable for requirements up to PL d / control category 3. To that effect,
the outputs must be connected to a safety-monitoring module meeting
at least the requirements of PL d / control category 3 to EN ISO 13849-
1. The outputs cannot be wired in series.
Inductive loads (e.g. contactors, relays, etc.) are to be provided with
suitable interference suppression circuitry.
Requirements for the connected safety-monitoring module:
• Dual-channel safety input, suitable for 2 or 4 p-type semi-conductor
outputs
Safety outputs Y1, Y2
The safety-monitoring module must tolerate internal functional with
cyclic switch-off of the safety outputs Y1 and Y2 for max. 2 ms (typically
< 1 ms). The switch-off stage of the test cycle is temporarily reduced
by an active ohmic discharge of the cable. The safety-monitoring
module does not need to have a cross-wire short monitoring function, if
necessary, the cross-wire short monitoring function must be disabled.
Safety outputs Y3 and Y4
The safety outputs Y3 and Y4 are antivalent switching outputs.
A short concordance (< 50 ms) must be accepted, as the AZM 200D
might present small switching delays.
Cable
If the cable input is realised through a metric M20 cable gland, this
gland must be dimensioned by the user so as to fit the cable used. A
cable gland with strain relief and suitable IP protection class must be
used.
5. Operating principle and diagnostic functions
Magnet control
In the power to unlock version of the AZM 200, the safety switch is
unlocked when the IN signal (= 24V) is set. In the power to lock version
of the AZM 200, the safety switch is locked when the IN signal (= 24 V)
is set.
5.1 Safety switch with diagnostic output
Mode of operation of the safety outputs
The unlocking of the safety switch causes the safety outputs Y3 and Y4
to be disabled. As long as the actuator is inserted in the safety switch,
the unlocked safety guard can be relocked, in which case the safety
outputs will be re-enabled.
The safety guard must not be opened.
Enabling path 1 is depicted by the safety outputs Y1/Y2 of the
AZM 200D. This path switches when the actuator is detected
for applications up to PL e / control category 4.
Enabling path 2 (Y3/Y4) enables (unlocks) both outputs,
when the actuator is detected AND the target is detected
AND the locked condition is detected.
Information for the selection of suitable safety-monitoring
modules can be found in the Schmersal catalogues or in the
online catalogue on the Internet: www.schmersal.net.
Operating principle of the electronic diagnostic output
The short-circuit proof diagnostic output can be used for central
visualisation or control functions, e.g. in a PLC.
The diagnostic output is not a safety-related output!
Error
Errors, which no longer guarantee the function of the safety switch
(internal errors) cause the safety outputs to be disabled. Any error that
does not immediately affect the safe functionality of the safety switch
(e.g. cross-wire short, temperature error, safety output, short circuit to
24 VDC) will lead to a delayed shut-down (refer to table 1).
After fault rectification, the sensor can be reset by opening and
relocking the relevant guard door. The safety outputs enable and allow
a restart. An interlocking chain must be permanently "locked" to enable
the reactivation.
The maximum cable length is 200 m (for ST2 M12 connectors approx.
20 m depending on the cable section used for an operating current
of 0.5 A). The maximum cable section is 1.5 mm², incl. conductuor
ferrules. Prior to the connection, the cable must be stripped by 40+5
mm and insulated by 5 mm.
4
If more than one fault is detected at the safety outputs Y1/Y2,
the AZM 200 will be electronically locked and a normal
fault reset will no longer be possible. To reset this type of
interlocking, the AZM 200, must be isolated from the power
supply after elimination of the error causes.
The safety outputs Y3 and Y4 are not monitored. This task is
assumed by the downstream safety-monitoring module.
To test the outputs, the AZM 200D must be operated at least
once a year (energisation of the IN input). The ambivalence
of the outputs Y3 and Y4 must be tested.
Error warning
A fault has occurred, which causes the safety outputs to be disabled
after 30 minutes. The safety outputs initially remain enabled. This
enables the shutdown of the process in a controlled manner. An error
warning is deleted in the slave when the error cause is eliminated.

6.2 Maintenance
We recommend a regular visual inspection and
functional test, including the following steps:
1. Check the fixing of the safety switch and the actuator
2. Remove particles of dust and soiling
3. Check cable entry and connections
Damaged or defective components must be replaced.
7. Disassembly and disposal
7.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
7.2 Disposal
