15.  Troubleshooting and assistance

15.1.  Fault reset

Proceed as follows:
1.  Open the safety guard.
2.  Switch off operating voltage at the interlocking module for min. 3 seconds or connect 24 V to the input RST for min. 3 

seconds.  

Alternatively, the internal reset (see 

7. System overview on page 11

) can be pressed for 3 seconds with a pointed 

object, e.g. ball-point pen.

 

¨

The green LED (State) flashes quickly (approx. 5 Hz in case of AR configuration). A self-test is performed during this time 

(approx. 10 s in case of AR configuration). The LED then cyclically flashes three times.

2.  Close the safety guard.

 

¨

The system is in normal mode again.

15.2.  Help on troubleshooting in the Internet

You will find a help file on troubleshooting under “Support” in the service area at www.euchner.de.

15.3.  Help on mounting in the Internet

You will find an animation on the mounting process at www.euchner.de.

15.4.  Application examples

You will find application examples on connecting the device to various control systems at www.euchner.de.
