2.4 Purpose
This non-contact, electronic safety sensor is designed for application in
safety circuits and is used for monitoring the position of movable safety
guards. In this application, the safety sensor monitors the position of
hinged, sliding or removable safety guards by means of the coded
electronic actuator.
The safety function consists of 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 a safety monitor.
The safety switchgears are classified according to ISO 14119
as type 4 switching devices. Designs with individual coding
are classified as highly coded.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.

The active areas of the sensor and the actuator have to face each
other. The safety sensor must only be used within the assured
switching distances ≤ sao and ≥ sar.
Safety sensor and actuator must be permanently fitted to
the safety guards and protected against displacement by
suitable measures (tamperproof screws, gluing, drilling of
the screw heads).
To avoid any interference inherent to this kind of system and any
reduction of the switching distances, please observe the following
guidelines:
• The presence of metal chips in the vicinity of the sensor is liable to
modify the switching distance.
• Keep away from metal chips.
• Minimum distance 100 mm between two safety sensors
as well as other systems with same frequency (125 kHz)

3.6 Adjustment
The continuous signal of the yellow LED signals the actuator detection; the
flashing of the yellow LED after a delay signals that the safety sensor is
actuated in the hysteresis area.
Recommended Adjustment
Align the safety sensor and actuator at a distance of 0.5 x sao.
The correct functionality of both safety channels must be checked by
means of the connected safety-monitoring module.
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 connection to the AS-Interface system is realised through an M8
or M12 connector. The connectors are A-coded. The connection to the
M12-plug is made (according to DIN EN 62026-2) to the AS-Interface
systems with an adapter cable of M8 / 4-pin (socket) on to M12 / 4-pin
(plug):

5. Functions and configuration
5.1 Programming the slave address
The slave address is programmed through the M8 connector. Any
address from 1 to 31 can be set by means of the AS-i bus master or a
hand-held programming device.
5.2 Configuration of the safety monitor
The RSS260 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.
5.3 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.
5.4 Actuator teaching / actuator detection
Safety sensors with standard coding are ready to use upon delivery.
Individually coded safety sensors and actuators will require the
following "teach-in" procedure:
1. Switch the safety sensor's voltage supply off and back on.
2. Introduce the actuator in the detection range. The teach-in procedure is
signalled at the safety sensor, yellow LED flashes (1 Hz).
3. After 10 seconds, brief cyclic flashes (3 Hz) request the switch-off
of the operating voltage of the safety sensor. (If the voltage is not
switched off within 5 minutes, the safety sensor cancels the "teachin" procedure and signals a false actuator by 5 yellow flashes.)
4. After the operating voltage is switched back on, the actuator must be
detected once more in order to activate the taught actuator code. In
this way, the activated code is definitively saved!
For ordering suffix -I1, the thus executed allocation of safety sensor and
actuator is irreversible.
For ordering suffix -I2, the "teach-in" procedure for a new actuator can be
repeated an unlimited number of times . When a new actuator is taught,
the code, which was applicable until the moment, becomes invalid.
Subsequent to that, an enabling inhibit will be active for ten minutes, thus
providing for an increased protection against tampering. The AS-i Duo
LED will flash red/green until the expiration of the time of the enabling
inhibit and the detection of the new actuator. In case of power failure
during the lapse of time, the 10-minutes tampering protection time will
restart.
Actuator detection (AD)
Device with actuator detection (AD) can emit the number of especially
coded actuators through the parameter port.
In this way, a non-safe identification of the actuator is possible.
Through the 4 bits of the parameter port, the actuators with the
numbers 01 - 15 can be detected and transmitted to the control.
If no actuator is detected, a 0 will be emitted.
Safety sensors and actuators with actuator detection must always be
used in pairs.

Yellow LED:Device status (enabling status) /
6.2 Error
Errors, which no longer guarantee the safe functionality of the
RSS260 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 Diagnostic information

6.4 Diagnostic signal periphery error
All error messages of the safety switchgear are also transmitted as a
"periphery error" to the control system through the AS-i master.
A "periphery error" (FID input of the AS-i chip) is signaled by the
alternating red and green flashing of the AS-i duo LED on the AS-i
device.
6.5 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.
