OPERATION
Use the POWER switch to turn the equipment on and off.
The cooling fan may come into operation even if the equipment has been turned off by using the POWER
switch (VFG25 model only).
CONTROL PANEL
The control panel is made-up of two LEDs: LED ON and TEST LED.
ON
The LED signals are described below:
LED ON
Description
LED colour
No output voltage. Equipment off device in protection.
Off
Power On.
Green
LED TEST
LED colour
Description
Equipment off
Off
No faults during operation.
Green
Protection device against overloads, over temperatures or low input voltage. Check the output wiring and the
equipment connected to the voltage reducer. Check the voltage reducer for proper installation. Check the
Red
input batteries group.
The output voltage is interrupted when the voltage limiter switches to fault mode.
The voltage reducer is automatically switched on as soon as normal operating conditions have been
restored (no overloads, correct over temperatures and battery voltage).
The LED TEST may turn to red colour even if the equipment is providing the required output voltage (green
LED ON). This indicates that faults have arisen but they have disappeared. To overcome the condition, turn
off the equipment and switch it back on.
