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.

The safety switchgears are classified according to

ISO 14119 as type 4 switching devices.

Designs with individual coding are classified as highly coded and are labelled with "Coding Level: High".

RSS36-AS

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.

Safety sensors and actuators with latching (ordering suffix 'R') must always be used in pairs. The latching force (approx. 18 N) exercised by the permanent magnet keeps hatches and small guards closed, also in a de-energised condition.

The system can be used as a door end stop up to 5 kg at 0.25 m/s.

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.

Ensure the safety sensor and actuator is mounted on a flat surface.

The universal mounting holes provide for a variable mounting by means of M4 screws (tightening torque 2.2 … 2.5 Nm).

The component can be mounted in any position. The labelled surfaces of the safety sensor and the actuator have to be opposite. The safety sensor must only be used within the assured switching distances

≤ s ao

and ≥ s ar

The safety component and the actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures (tamperproof screws, gluing, drilling, pinning).

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)

3.2 Accessories

Sealing kit

• Ordering code 101215048

• 8 plugs and 4 washers

• to seal the mounting holes and as spacer

(approx. 3 mm) to facilitate the cleaning below the mounting surface

There are new switch distances as per the table below owing to the necessity of technical modifications (V2).

Please check the design of your guard system following installation to ensure adherence to the secured switch distances (≤ s ao

and ≥ s ar

) in accordance with the specified values and adjust the guard system accordingly.

The positions of the designations V2 should be gleaned from the dimensional drawings under 3.3.

3.5 Adjustment

The continuous signal of the yellow LED signals the actuator detection; the flashing of the yellow LED 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 s ao

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 M12 connector. The M12 connector is A-coded. The wiring configuration of the M12 connector is determined as follows (to EN 62026-2):

Pin assignment M12 connector spare

4 3

AS-i -

AS-i +

1 2 spare

5. Functions and configuration

5.1 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.

5.2 Configuration of the safety monitor

The RSS36 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.

RSS36-AS

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

"teach-in" procedure and signals a false actuator by 5 red 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 that 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:

AS-Interface supply voltage /

AS-Interface communication error /

Slave address = 0 /

Periphery error detected /

Enabling inhibit (tamper protection time) active

Device status (enabling status) / hysteresis signal / device error

6.2 Error

Errors, which no longer guarantee the safe functionality of the RSS36 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.
