2. Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
AZ 200 ST-T-AS
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 non-contact, electronic safety switchgear is designed for
application in AS interface Safety at Work and is used for monitoring the
position of movable guard systems.
The safety switchgears are classified according to ISO 14119
as type 4 interlocking devices.
The safety function 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.
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 the safety monitor.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.

3. Mounting
3.1 General mounting instructions
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.
For fitting the AZ 200 AS 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).
Minimum distance between two safety sensors: 100 mm.
Fitting of the actuator
Refer to the mounting instructions manual for the corresponding
actuator.
The actuator must be permanently tted to the safety
guards and protected against displacement by suitable
measures (tamperproof screws, gluing, drilling of the
screw heads).

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 AZ 200 AS solenoid interlock is supplied through the AS-Interface
system. The power supply of the safety switch must provide 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 x 1 connector has an A-coding. The wiring
configuration of the M12 connector is defined as follows (to EN 62026-2):
free (max. 30 VDC)

5. Functions and configuration
5.1 Mode of operation of the safety outputs
The safety outputs of the AS-i safety monitor are enabled, when the
following conditions are met:
• guard door detected
• the actuator is inserted
The opening of the AZ 200 AS safety switch causes the safety outputs of
the AS-i safety monitor to be disabled. When the safety guard is closed,
the safety outputs are re-enabled.
5.2 Configuration of the safety monitor
The AZ 200 AS component must be parameterised in the configuration
software ASIMON as double channel dependent monitoring device with
a synchronisation time of typically 100 ms. (Optional: start-up test and
local acknowledge, refer to ASIMON manual).
The configuration of the safety monitor must be tested and
confirmed by a qualified and authorised safety expert/safety
engineer.
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 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.

6. Diagnostic
6.1 LED display
The safety switchgear signals the operational state as well as errors
through three coloured LEDs installed on the front side of the device.
The LEDs have the following meaning (in accordance with EN 62026-2):
LED red/green
(AS-i Duo LED):
AS-Interface supply voltage /
AS-Interface communication error /
slave address = 0
LED red (Fault): Device error (see table 2)

6.2 Error / Error warning
Errors, which no longer guarantee the function of the AZ 200 AS
(internal errors) cause the safety outputs to be disabled. Any error that
does not immediately affect the safe functionality of the AZ 200 AS (e.g.
the ambient temperature too high) will lead to a delayed shut-down (refer
to table 3).
After fault rectification, the sensor can be reset by opening the relevant
guard door. The safety outputs can be switched back on, thus enabling
the machine.

Error warning
If a fault has occured, which still guarantees the function of the safety
switch, the system is safely switched off after 30 minutes. The safety
outputs initially remain enabled. The error message can be read out
through the parameter port (refer to Table 1). Depending on the type
of fault, the machine is not immediately shut down. The control system
obtains a preliminary message, which enables a controlled shutdown of
the process.
An error warning is deleted/reset as soon as the error cause is
eliminated.
6.3 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.

7. Set-up and maintenance
7.1 Functional testing
The safety function of the safety components must be tested. The
following conditions must be previously checked and met:
1. Check max. axial misalignment of actuator and safety switchgear
2. Check the switch enclosure for damage
3. Remove particles of dust and soiling
7.2 Maintenance
We recommend a regular maintenance, including the following steps:
• Check the fixing of the safety switch and the actuator
• Check max. axial misalignment of actuator and safety switch
• Check the switch enclosure for damages
• Remove soiling
Measures must be taken to protect against manipulation or
against the bypassing of safety device, for example, using an
extra actuator.
Damaged or defective components must be replaced.
8. Disassembly and disposal
8.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
8.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
