DGF7 Display reference manual, rev. 1, feb 22, 2022 Ground Fault Systems B.V.
By means of parameter P2 the relay test feature can be switched off, so as not to allow for personnel to
cause inadvertent trips from a door mounted operator interface.
Tests can still be started from the DGF7-3 base unit.
If one tries to start a test while the feature is switched off, the display will show a 1,5 seconds message
‘OFF’. If one tries to start a test while the system is already tripped, the display will show a 1,5 seconds
message ‘---’. See
chapter 3 for the parameter settings.
2.1.7 LCD test
The LCD panel can be tested at all times by keeping the ‘RESET’ button pressed longer than 2 seconds.
All segments of the LCD panel will turn on, displaying
8.8:8.8
until the pushbutton is released.
2.1.8 Alarm code display
The current version of the DGF7-3 has no alarm functions.
The display will show
AL:--
if the ‘SHOW ALARM’/ ‘RESET’ button is pressed.
2.2 Datalink error code
At the moment only one error code is used:
E:04.
The DGF7 Display does not receive data via the datalink. This code may be seen for a few seconds when
the base unit is powered down.
