5.3  Interrogation of module to confirm the set nominal current

Only for circuit protection modules with adjustable nominal current. 

 

► Press the ON/OFF/reset button of the requested channel between 2 and 5 

seconds.

 

> The status LED of the selected channel flashes red once.

 

> The status LED flashes orange to display the set nominal current. The LED 

Flashes red once to confirm completion of the cycle. The LED flashes orange, 

once or multiple times, in accordance with nominal current setting in amperes 

(orange flashing once = 1 A; orange flashing twice = 2 A; etc.).

 

> The set nominal current is displayed five times. After 5 cycles the display 

changes to the current operating status.To interrupt/stop the interrogation cycle, 

and return to normal status indication mode, press the ON/OFF/reset button of 

the requested channel at any time.

5.4  Setting of the nominal current

Only for circuit protection modules with adjustable nominal current.

 

► Set the nominal current via IO-Link using a corresponding parameter setting 

software.
