Special versions

• For special versions, which are not listed in the ordering code, these specifications apply accordingly, provided that they correspond to the standard version.

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 safety outputs when the safety guard is opened and maintaining the safe switched off condition of the safety outputs for as long as the safety guard is open.
• The safety switchgears are classified according to ISO 14119 as type 4 interlocking devices.
• Designs with individual coding are classified as highly coded.
• Safety sensors and actuators with latching (ordering suffix ‘R’) always must 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 diagnostic output of the safety sensor alternatively can be used as a conventional output or as a “serial output“ with input and output channel.

Series-wiring

• Series-wiring can be set up. In the case of a series connection, the risk time remains unchanged and the reaction time increases by the sum of the reaction time of the inputs per additional unit specified in the technical data.
• The quantity of devices is only limited by the cable drops and the external cable fuse protection, according to the technical data.
• Up to 31 device variants with serial diagnostics can be wired in series.
• The user must evaluate and design the safety chain in accordance with the relevant standards and the required safety level.
• If multiple safety sensors are involved in the same safety function, the PFH values of the individual components must be added.
• The entire concept of the control system, in which the safety component is integrated, must be validated to the relevant standards.

Warning about misuse

• In case of improper use or manipulation of the safety switchgear, personal hazards or damages to machinery or plantcomponents cannot be excluded.
• There are no residual risks, provided that the safety instructions as well as the instructions regarding mounting, commissioning, operation and maintenance are observed.

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 (≤sao and ≥ sar) 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.

With the combination of “old sensor – new actuator (V2)” there may be limitations in availability owing to the reduced s ao (8 mm). This change has no affect on the performance level. The side allows for a maximum height misalignment (X) of sensor and actuator of ± 8 mm (e.g. mounting tolerance or due to guard door sagging). The axial misalignment (y) is max. ± 18 mm.

• Latching versions X ± 5 mm, Y ± 3 mm.
• The latching force will be reduced by misalignment.

Actuating curves
The actuating curves represent the typical switching distance of the safety sensor during the approach of the actuator subject to the actuating direction

Preferred actuation directions: from front or from side

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 sao.
• The correct functionality of both safety channels must be checked by means of the connected safety-monitoring module.

Electrical connection

General information for electrical connection

The electrical connection may only be carried out by authorised personnel in a de-energised condition.

• The safety outputs can be integrated into the safety circuit of the control system.
• For applications of PL e / category 4 to EN ISO 13849-1, the safety outputs of the safety sensor or of the sensor chain must be wired to a safety monitoring-module of the same category.
• The required electrical cable fuse protection must be integrated in the installation.
• Protection is not required when pilot wires are laid. The cables however must be separated from the supply and energy cables.
• The max. fuse rate for a sensor chain depends on the section of the connecting cable of the sensor.
• Requirements for the connected safety-monitoring module: dual-channel safety input, suitable for p-type sensors with NO function
• Information for the selection of suitable safety-monitoring modules can be found in the Schmersal catalogues or in the online catalogue on the Internet: products.schmersal.com.
• As an alternative to a safety-monitoring module, the safety sensors of the CSS 34F0 or CSS 34F1 series can also be used as first sensor of a series-wired chain for the direct control and monitoring of safety contactors (refer to operating manual of CSS 34F0 / CSS 34F1).
• If the safety sensor is wired to relays or to non-safety relevant control components, a new risk analysis must be carried out.
• The sensors cyclically switch off the safety output to test them.
• The safety-monitoring module therefore does not need to be equipped with a cross-wire short detection.
• The switch-off times must be tolerated by the safetymonitoring module.
• The switch -off time of the safety sensor is additionally extended depending on the cable length and the capacity of the cable used.
• Typically, a switch-off time of 250 μs is reached with a 30-m connecting cable.

Configuration of the safety-monitoring module

• If the safety sensor is connected to electronic safety-monitoring modules, we recommend that you set a discrepancy time of min. 100 ms.
• The safety inputs of the safety-monitoring module must be able blanking a test impulse of approx. 1 ms.
• 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.

Serial diagnostic -SD

Cable design

• The wiring capacitance of the connecting cable of the safety sensor must not exceed 50 nF.
• Depending on the strand structure, normal unshielded 200 m long control cables LIYY 0.25 mm² to 1.5 mm² have a wiring capacitance of approx. 20 … 50 nF
• On wiring SD devices, please pay attention to the voltage drop on the cables and the current carrying capacity of the individual components.

Accessories for the series-wiring

• For convenient wiring and series-wiring of SD components, the SD junction boxes PFB-SD-4M12-SD (variant for the field) and
• PDM-SD-4CC-SD (variant for control cabinet on carrier rail) are available along with additional comprehensive accessories.
• Detailed information is available on the Internet, products.schmersal.com.

Wiring examples for series-wiring

• Series-wiring can be set up. In the case of a series connection, the risk time remains unchanged and the reaction time increases by the sum of the reaction time of the inputs per additional unit specified in the technical data.
• The number of components is only limited by the external cable protection according to the technical data and the line loss. Series-wiring of up to 31 RSS 36 … SD components with serial diagnostics is possible.
• The application examples shown are suggestions. They however do not release the user from carefully checking whether the switchgear and its set-up are suitable for the individual application. The application examples shown are suggestions.

Wiring example 1: Series-wiring of the RSS 36 with conventional diagnostic output

• The voltage is supplied to both safety inputs of the last safety sensor of the chain (considered from the safetymonitoring module).
• The safety outputs of the first safety sensor are wired to the safety-monitoring module. The diagnostic output can be connected for instance to a PLC.

Y1 and Y2 = Safety outputs → Safety monitoring module

Wiring example 2: series-wiring of the RSS 36 with serial diagnostic function

• In devices with the serial diagnostics function (ordering suffix -SD), the serial diagnostics connections are wired in series and connected to a SD-Gateway for evaluation purposes.
• The voltage is supplied to both safety inputs of the last safety sensor of the chain (considered from the safety-monitoring module).
• The safety outputs of the first safety sensor are wired to the safety-monitoring module. The serial Diagnostic
• Gateway is connected to the serial diagnostic input of the first safety sensor.
• Y1 and Y2 = Safety outputs → Safety monitoring module SD-IN → Gateway → Field bus

Actuator coding

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. Energise the safety sensor.
2. Introduce the actuator in the detection range. The teach-in procedure is signalled at the safety sensor, red LED on, yellow LED flashes (1 Hz).
3. After 10 seconds, brief yellow cyclic flashes (3 Hz) request the switch-off of the operating voltage of the solenoid interlock. (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. Once the operating voltage is switched back on, the actuator must be detected once more in order to activate the actuator code that has been taught in. In this way, the activated code is definitively saved!
   • For ordering suffix -I1, the executed allocation of safety switchgear 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 green LED will flash 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.

Working principle and diagnostic function

Mode of operation of the safety outputs

• The safety outputs can be integrated into the safety circuit of the control system.
• The opening of a safety guard, i.e. the actuator is removed out of the active zone of the sensor, will immediately disable the safety outputs of the sensor.

Diagnostic-LEDs

• The safety sensor indicates the operating condition and faults by means of three-colour LEDs located in the lateral surfaces of the sensor.
• The following LED indicators are the same for safety sensors with conventional diagnostic output as for those with a serial diagnostic function.
• The green LED indicates that the safety sensor is ready for operation. The supply voltage is on and all safety inputs are present.
• Flashing (1Hz) of the green LED signals that a voltage is missing on one or both of the safety inputs (X1 and/or X2).
• The yellow LED always signals the presence of an actuator within range. If the actuator is operating in the limit area of the sensor switching distance, it will be indicated by flashing.
• The flashing can be used to prematurely detect variations in the clearance between the sensor and the actuator (e.g. sagging of a safety guard).
• The sensor must be adjusted before the distance to the actuator increases and before the safety outputs are disabled, thus stopping the machine. If an error is detected, the red LED will be activated.

Operating principle of the electronic diagnostic output

• A diagnostic output additionally indicates the switching condition of the safety switchgear. These signals can be used in a downstream control.
• The short-circuit proof diagnostic output OUT can be used for central visualisation or control tasks, 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 switchgear (internal errors) cause the safety outputs to be disabled within the duration of risk.
• After fault rectification, the error message is reset by opening and reclosing the corresponding safety guard.

Error warning

• A fault that does not immediately endanger the safety function of the safety switchgear (e.g. too high ambient temperature, safety output at external potential, cross-circuit) leads to delayed shutdown.
• This signal combination, diagnostic output disabled and safety channels still enabled, can be used to stop the production process in a controlled manner.
• An error warning is deleted when the cause of error is eliminated.
• If the fault warning remains on for 30 minutes, the safety outputs are also switched off (red LED flashes).

Table 1: Examples of the diagnostic function of the safety-sensor with conventional diagnostic output

III.| Actuated, actuator in limit area| Off| Off| Flashes (1Hz)| 24 V pulsed| 24 V| The sensor must be adjusted before the distance to the actuator increases and before the safety outputs are disabled, thus stopping the machine.
IV.| Error warning, sensor actuated| Off| Flashes| Off| 0 V| 24 V| After 30 minutes if the error is not rectified
V.| Error| Off| Flashes| Off| 0 V| 0 V| Refer to table with flash codes

VII.| Protection time| Flashes| Off| Off| 0 V| 0 V| 10 minutes pause after re- teaching
VIII.| Error in input circuit X1 and/or X2| Flashes (1Hz)| Off| Off| 0 V| 0 V| Example: door open; a door in the safety circuit upstream is also open.
IX.| Error in input circuit X1 and/or X2| Flashes (1Hz)| Off| On| 24 V| 0 V| Example: door closed, a door in the safety circuit upstream is open.

Safety-sensors with serial diagnostic function

• Safety sensors with serial diagnostic cable have a serial input and output instead of the conventional diagnostic output.
• If RSS / CSS safety sensors are wired in series, the safety channels as well as the inputs and outputs of the diagnostic channels are wired in series.
• Up to 31 safety switchgear devices can be connected in series with serial diagnostics. For the evaluation of the serial diagnostics line either the PROFIBUS-Gateway SD-I-DP-V0-2 or the Universal-Gateway SD-I-U-… are used. This
• SD-Gateway is integrated as a slave in an existing field bus system. In this way, the diagnostic signals can be evaluated by means of a PLC. The necessary software for the integration of the SD-Gateway is available for download at products.schmersal.com.
• The response data and the diagnostic data are automatically and permanently written in the assigned input byte of the
• PLC for each safety sensor in the series-wired chain.
• The request data for each safety sensor are transmitted to the device through an output byte of the PLC.
• In the event of a communication error between the SD-Gateway and the safety sensor, the switching condition of the safety output of the safety sensor is maintained.
  • Bit 0: safety outputs enabled
  • Bit 1: safety sensor actuated, actuator identified
  • Bit 4: both safety inputs live
  • Bit 5: safety sensor actuated in hysteresis area
  • Bit 6: error warning, switch-off delay activated
  • Bit 7: error, safety outputs switched off

Error

• Errors which no longer guarantee the function of the safety switchgear (internal errors) cause the safety outputs to be disabled within the duration of risk.
• The fault is reset, when the cause is eliminated and bit 7 of the request byte changes from 1 to 0 or the safety guard is opened.
• Faults at the safety outputs are only deleted upon the next release, as the fault rectification cannot be detected sooner.

Error warning

• A fault that does not immediately endanger the safety function of the safety switchgear (e.g. too high ambient temperature, safety output at external potential, cross-circuit) leads to delayed shutdown.
• This signal combination, diagnostic output disabled and safety channels still enabled, can be used to stop the production process in a controlled manner.
• An error warning is deleted when the cause of error is eliminated.
• If the fault warning remains on for 30 minutes, the safety outputs are also switched off (red LED flashes).

Diagnostic error (warning)

• If an error (warning) is signalled in the response byte, detailed fault information can be read out.

Set-up and maintenance

The safety function of the safety components must be tested. In the case of correct installation and adequate use, the safety switchgear features maintenance-free functionality. A regular visual inspection and functional test, including the following steps, is recommended:

1. Check fixation of the safety switch and the actuator.
2. Fitting and integrity of the cable connections.
3. The system is free of dirt and soiling (in particular metal chips).

Adequate measures must be taken to ensure protection against tampering either to prevent tampering of the safety guard, for instance by means of replacement actuators. Damaged or defective components must be replaced.

Disassembly and disposal

Disassembly

• Disposal: The safety switchgear must be disposed of in an appropriate manner in accordance with the national prescriptions and legislations.
