sensor® PRO STS
Touchless safety sensor with coding
Teach-in variant "individual"
The first permitted actuator is detected immediately after the supply voltage is applied, if it
is located in the detection range of the sensor. Each additional teach-in process must be
done as described in the following:
1. Apply the supply voltage to the safety sensor.
2. Bring an allowable actuator into the detection range of the sensor.
3. Actuator is detected, red LED flashes six times.
4. After 10 s the LED switches to yellow flashing.
5. Switch off power supply within the next 2 min.
6. Re-apply power supply, the programming procedure is finished and the actuator is ac-
cepted.
7. If an actuator is re-taught, the safety sensor disables the code of the previous process, so
this is no longer permitted.
8. Do not remove the actuator during the process, as long as it is located in the detection
area.
If the teach-in procedure is terminated, the supply voltage must be switched off and the
process restarted. The teaching-in of actuators to a security sensor can be performed an un-
limited number of times, as long as the code of the actuator is not locked in the sensor.
Maintenance
If the safety sensor correctly installed and used as intended, no maintenance measures are
required. We recommend periodically carrying out a visual and functional test:
•
Check the safety sensor and actuator for tightness.
•
Check the connection cable for damage.
Damaged or faulty equipment must be replaced with original spare parts! In variant
"unique", the safety sensor AND actuator must be replaced. For the "individual" variant, a
teach-in process must be performed after replacement of the safety sensor OR the actua-
tor.
Troubleshooting
Safety output faults
Flash code
Cause
Short circuit between safety outputs to ground or to +24 V DC.
Wire breakage
Remedy
•
Switch off supply voltage.
•
Eliminate short/wire break at the output.
Re-apply supply voltage.
•
Safety input faults
Flash code
Cause
Short circuit between safety inputs, to ground or to+24 V DC.
Wire breakage
Remedy
Switch off supply voltage.
•
Eliminate short/wire break at the output.
•
Re-apply supply voltage.
•
Safety input faults
Flash code
Cause
•
EDM automatic: Error on connected safety relay.
•
EDM manual: Start pulse does not take place in the defined
area.
•
All variants: Wire breakage.
Remedy
•
Switch off supply voltage.
•
Check safety relay or set start pulse correctly, check for bro-
ken wire.
•
Re-apply supply voltage.
Error overvoltage or undervoltage
Flash code
Cause
The supply voltage has not been applied in the defined re-
•
gion.
Remedy
Switch off supply voltage.
•
Ensure correct supply voltage and reconnect it.
•
Temperature outside the acceptable range
Flash code
Cause
•
The defined temperature range has been exceeded or un-
dershot.
Remedy
Switch off supply voltage.
•
•
Ensuring proper ambient temperature.
•
Re-apply supply voltage.
Incorrect actuator
Flash code
Cause
•
Incorrect actuator in the detection range of the sensor.
Remedy
•
Use correct actuator.
Internal device error
Flash code
Cause
•
Internal device error.
Remedy
•
Switch off power supply and re-connect.
If the errors described cannot be resolved, the device must be replaced to ensure the safety
function.
