Display – The EPS-D is equipped with an easy to use display.
The Display has 4 LEDs for status indication and 2 buttons marked A and B. In case
of an alarm, the unit will activate a buzzer to alert the user of the situation.
The A and B buttons are used to browse through the information in the display.
Button A is used to browse to the left and the B button is used to browse to the right.
If the unit isn’t started in a settings mode and no alarm is active, then nothing can be
altered through the use of the buttons.
By pressing the right button following information will be presented in the display:
Version – indicates the PCB version, e.g. LV6, and the firmware version e.g 16.
Load VA – indicates the load in VA.
Watt Cos fi - 15 Watt 0.87 VA: indicates the load in watt, as well as its
pf(cosƒ).
Ref load – indicates the load that has been saved as reference load for the
weekly test.
Battery Voltage – usually 27.4 Vdc +-0.2 V is displayed when the battery is
fully charged.
Discharge – indicates the direct current from the battery during battery
operation.
Charge – indicates the charging current to the battery. Usually, 0-1 Ampere is
displayed when the battery is fully charged.
Mains– shows the supply phase voltage, typically 230 V.
Invert – indicates true RMS load voltage during power outages. Displays zero
when grid is present, and typically 230 V during battery operation.
EL - indicates set value for the earth leakage monitor (30 mA) and true earth
leakage, e.g. 4 mA.
