Operating principles 

 

The meaning of the push-buttons in each menu is shown on the display. 

 

Pressing the 

MENU

 push-button invoke the parameter setting menu. 

 

Pressing the 

SEL

 push-button activates transition to the inversely  

displayed parameter settings menu. 

 

Short pressing the 

ESC/SET

 push-button causes exit from the menu  

without memorizing the new parameter value. 

 

Prolonged pressing the 

ESC/SET

 push-button causes memorizing  

the new parameter value and the menu will end than. 

 

When no push-button is pressed within 30 seconds, the new value  
setting menu will be automatically terminated.   

 

When no push-button is pressed within 5 minutes, display goes OFF. 

 

The insulation monitoring device is operational even if there is nothing  
shown on the display (display is not active). 

 

The display is recovered by pressing any of the push-buttons below the display. 

 

The display is restored by pressing the remote test button if tTEST is set to a value greater than zero. 

 

After selecting the menu 

Lock Up

 the control buttons are locked and the measured value is displayed. 

 

The unlocking of the device’s control buttons is realized while holding the middle and right button for 5 seconds.

 

 

 

Releasing the 

FAULT1

 or 

FAULT2

 relay is realized by the middle push-button on the device or by the RS485 

ISOLGUARD communication line RS485 order. 

 

FAULT1

 or 

FAULT2

 relay status change, eventually initiation and termination the device test is indicated by a short 

display flash.
