these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Comprehensive quality insurance to 2006/42/EC
Schmersal is a certified company to appendix X of the Machinery
Directive. As a result, Schmersal is entitled to autonomously conduct
the conformity assessment procedure for the products listed in
Appendix IV of the MD without involving a notified body. The EC
prototype test certificates are available upon request or can be
downloaded from the Internet at www.schmersal.com.
The safety switchgears are classified according to
ISO 14119 as type 4 interlocking devices.
2.4 Destination and use
The non-contact, electronic CSS 8-180 safety sensor (hereafter called
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 CST 180-1 or
CST 180-2 actuators.
Mode of operation of the safety outputs
The opening of a safety guard, i.e. the actuator is removed out of the
active zone of the safety sensor, will immediately disable the safety
outputs (also refer to Switching distance of the safety sensor).
Faults which no longer guarantee the functioning of the safety sensor
(internal fault,) will also disable the safety outputs immediately. Any
error that does not immediately affect the safe functioning of the safety
sensor (e.g. the ambient temperature too high, interference potential
at a safety output, cross-wire short) will lead to a delayed shut-down.
In this situation, the diagnostic output will be switched off after approx.
10 seconds. The safety outputs are disabled when the fault is active
for 1 minute. This signal combination, diagnostic output disabled and
safety outputs still enabled, can be used to shut down the machine in
a controlled manner. After fault rectification, the error message is reset
by opening and re-closing the corresponding safety guard. The safety
outputs will switch, thus enabling the machine. For the release, the chain
of sensors must be permanently actuated.
A cross-wire short at the safety outputs of a sensor chain will
load the sensor from the place where the fault is located up
to the end of the chain. The fault therefore can be signalled
by multiple sensors. Starting from the safety-monitoring
module, the cross-wire short is located before the first sensor
signalling the fault.
Series-wiring
Max. 16 sensors can be wired in series. A 200 m long sensor chain can
be set up. Wiring examples for series-wiring, refer to appendix
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.

3. Mounting
3.1 General mounting instructions
During fitting of the actuator and the sensor, the requirements
of ISO 14119, especially paragraph 7 must be observed!
The component can be mounted in any position. The only condition
is that, the active surface of the safety sensor and the actuator are
opposite. The sensor enclosure must not be used as an end stop.
The safety sensor must only be used within the assured switching

The safety sensor and the corresponding actuator can be fixed using
the supplied M18 nuts (A/F 24). The max. tightening torque of the
supplied screws is 500 Ncm. Alternatively, the H18 fixing clamp
(accessory) can be used for the fixation of the safety sensor.
A concealed mounting is possible, however this reduces the switching
distance. The reduction will be lower, when the safety sensor protrudes
a few mm.
The CST 180-1 actuator has two fixing holes displaced by 90°. The
max. tightening torque of the supplied screws is 100 Ncm.
The CST-180-2 actuator is screwed into a prepared tapped hole M 18.
Use the slot to the front.
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:

3.3 Adjustment
The LED in the end cap of the safety sensor can be used as
adjustment tool.
The yellow flashing LED of a sensor signals if an adjustment of the
switching distance is required. Reduce the distance between the sensor
and the actuator, until the LED in the end cap of the safety sensor is
continuously lit yellow. In this position, a reliable switching position
of the sensor is obtained. (also refer to "Operating Principle of the
Diagnostic Outputs").
The proper functionality must always be checked by means of the
connected safety-monitoring module.
3.4 Switching distance
The graphs show the switch-on and switch-off points of the sensor
due to the approach of the actuator. The maximum misalignment of
the actuator with regard to the sensor centre is 7 mm. A concealed
mounting of the sensor and the actuator will reduce the switching
distance.

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 power supply for the safety sensors must provide protection
against permanent over-voltage. Under fault conditions, the voltage
must not exceed 60 V. supply units according to IEC 60204-1 is
recommended.
The safety outputs can be integrated into the safety circuit of the control
system. For applications of PL e / control category 4 to ISO 13849-1,
the safety outputs of the safety sensor or sensor of the chain must be
wired to a safety monitoring module of the same control category .

The safety-monitoring module must tolerate internal functional tests of
the sensors with cyclic switch-off of the sensor outputs for max. 1 ms.
The safety-monitoring module must not be equipped with a cross-wire
detection function. Short-circuit recognition by the evaluation is not
necessary.
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.
4.2 Series-wiring
A 200 m long sensor chain can be set up. Please note that voltage
losses could occur (due to cable length, cable section, voltage drop/
sensor)! For longer cable lengths, the section of the connecting cables
must be taken as large as possible.
Wiring examples for series-wiring, refer to appendix
4.3 Note on the total length of a safety sensor chain
The voltage drop of a long sensor chain must be taken into account
when planning the wiring.

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.
5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested. The
following conditions must be previously checked and met:
1. Fitting of the sensor and the actuator
2. Fitting and integrity of the power cable
3. The system is free of dirt and soiling (in particular metal chips)
5.2 Maintenance
In the case of correct installation and adequate use, the safety sensor
features maintenance-free functionality.
A regular visual inspection and functional test, including the following
steps, is recommended:
1. Check the fitting and integrity of the safety sensor, the actuator and
the cable
2. Remove possible metal chips
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.

6. Diagnostic functions
6.1 Operating principle of the diagnostic LED's
The safety sensor indicates the operating condition and faults by means
of three-colour LED's located in the lateral surfaces of the sensor.
The green LED indicates that the safety sensor is ready for operation.
The sensor is not actuated. When the safety sensor is actuated by the
CST 180 actuator, the indication switches from green to yellow. The
safety outputs of the safety sensor are enabled. If the actuator is near
the limit of the sensor's switching distance, the yellow LED will flash.
The safety outputs remain enabled. The sensor can be readjusted
before the safety outputs are disabled, thus stopping the machine.
Errors in the coding of the actuator, at the outputs of the sensor or in
the sensor are signalled by the red LED. After a short analysis of the
active fault, signalled by the red permanent signal, the defined error is
indicated by flash pulses. The safety outputs are enabled in a delayed
manner, when the fault is active for 1 minute.
Flash codes red diagnostic LED
LED indication (red) Error cause
1 flash pulse Error output Y1
2 flash pulses Error output Y2
3 flash pulses Cross-wire Y1/Y2
4 flash pulses Ambient temperature too high
5 flash pulses Wrong or defective actuator
Continuous red Internal error
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 electronic diagnostic output signals faults before the safety outputs
are disabled, thus enabling a controlled shutdown.
The diagnostic output is not a safety-related output!
The closed condition of the safety guard, i.e. the sensor is actuated,
is indicated through a positive signal. If the sensor is operating near
the limit of its switching distance, e.g. due to the sagging of the safety
guard, the sensor will emit a 2 Hz cyclic signal before the safety outputs
are disabled. An active fault will disable the diagnostic output after a
short analysis.

this sensor type. The CSS 8-180-2P-Y-L safety sensors have separated input and output lines. The outputs of the first sensor are wired to the inputs
of the next sensor and so on. A 200m long sensor chain can be set up.
A safety sensor of the CSS 8-180-2P-Y-L type can also be used as a terminal device in a chain; in this situation, additional wiring is required.
The positive operating voltage must be wired to both safety inputs.

Series-wiring of safety sensors with common connecting cable for the inputs and outputs
CSS 8-180-2P-E-L as an individual component or the terminal device of the chain. The voltage supply to the safety inputs is realised internally
in this sensor type. The series-wiring of multiple safety sensors is realised by wiring in the control cabinet or in on-site junction boxes. A
CSS8-180-2P+D-M-L safety sensor can also be used as a terminal device of a chain. In this case, the positive operating voltage must be wired to
both safety inputs of this safety sensor.
