Read Set Parameters; Self-Diagnosis / Error Indications - IMI Norgren 34D Series Operation Manual

10. Operation
After power on, the unit is in the Run mode (= normal operating mode). It carries out its
measurement and evaluation functions and provides output signals according to the set
parameters.
Operating indicators → 7 Operating and display elements.

10.1 Read set parameters

► Press [●].
► Press [▲] or [▼] until the requested parameter is displayed.
► Briefly press [●].
o The unit displays the corresponding parameter value for approx. 30 s; then it changes
to the process value display.

10.2 Self-diagnosis / error indications

The unit has many self-diagnostic options.

It monitors itself automatically during operation.
Warnings and faults are displayed (even if the display is deactivated), in addition they are

available via IO-Link.
