5.1 Using the diagnostic box
Switch the diagnostic box on. Then connect it to the opto- coupler receptacle on sensor head bottom.
Keep the LED`s and the phototransistors of the opto- coupler clean for proper data transmission.
5.1.1 Operation and error codes of the diagnostic box
Note:
If a combination of push button operations is requested ( f. i. ST + ENT), the buttons must be
operated in a short time distance.
Example: ST + ENT initiates a self test. The display says „WAIT-TEST RUN“ until the self test is
finished.
