LED Stop Operation (red color)
It warns about the imminent inverter stop (default parameter = 3 min.) and the
consequent load shutdown as result of:
• The battery is fully discharged and the load cannot be transferred on utility.
•
Overtemperature or overload condition (>125%) and the load cannot be
transferred on utility.
LED Alarm (yellow color)
It blinks when one or more alarm is activated. The internal buzzer is ON.
The LED remains lighted (with the alarm condition still present) and the buzzer
stops when the key “MUTE” is pressed.
The LED is also lit when the load is not protected by UPS or in case Q1 is open.
LED Operation (green color)
When lit, indicates that the UPS is functioning correctly and the load is system
protected (Load supplied from inverter).
When blinking, indicates that a regular maintenance service is needed (SERVICE
REQUIRED).
May be reset by a service technician only.
See Section 9 – Maintenance – Service check.
The LED is OFF when the output switch Q1 is open, indicating that the Inverter is in
service mode, not supplying the load.
