6 Appendix

6.2 Failure monitoring

Following possible error sources are monitored continuously when SENS = ON/AUTO:

Source

Fault

Characteristic

Command signal PIN 10

4... 20 mA

Out of range or broken wire

The output will be switched off.

Command signal PIN 6

4... 20 mA

Out of range or broken wire

The output will be switched off.

Feedback signal PIN 13
4… 20 mA

Out of range or broken wire

The output will be switched off.

Feedback signal PIN 14
4… 20 mA

Out of range or broken wire

The output will be switched off.

EEPROM
(when switching on)

Data error

The output is deactivated.

The module can only be acti-
vated by saving the parameters
again!

CAUTION:

Take care of the EOUT command. Changes will influence the behavior.
