EARTH FAULT ALARM
Ensure that the earth fault alarm is not inhibited by the Micro-controller Board.
Connect an adjustable resistor in series with a multimeter capable of reading 0 to
50mA. Place the resistor/meter from earth to the charger output (+Ve). Adjust the
resistor to obtain the required earth fault current reading on the multimeter. Then
adjust P1 potentiometer on the Interface Board until the Earth Fault LED (D14 on the
Interface board) comes On. Recheck the setting when the resistor/meter is
connected from earth to charger (-Ve).
To inhibit this alarm, set the Earth Fault Inhibit set-point to ON in the Sub Menu 5,
Latches and Inhibit Settings.

USER ADJUSTABLE SET POINT INSTRUCTIONS.
The following procedure should be employed when adjusting any set point.
1) Select the required set point from the programmable set point
descriptions in Section 6.0 of this manual.
2) Follow the instructions contained in the User adjustable set point
instructions flow chart on page 24 of this manual.
3) Once the set point has been adjusted and programming mode exited, it
is a good idea to check the float and boost settings to ensure they have
not been accidentally changed during set point adjustment.
This should be done with a separate multimeter connected across the
battery terminals.
