FUNCTIONS AND SIGNALS

Visual signals:
the leds illustrated on page 6, have the following functions:
3 Green MAINS LED
- on: mains normal, inverter synchronized.
- flashing: mains out of tolerance level but present and sufficient for correct operation, or
inverter not syncronized.
- off: mains absent or too low in relation to the load.
- on in service mode: neutral sensor enabled.
- off in service mode: neutral sensor inhibited.
8 Green INVERTER LED
- on: inverter operation.
- off: inverter disactivated or defective.
- on in service mode: Extended PLL Lock Range on.
- off in service mode: Extended PLL Lock Range inhibited.
4 Yellow BATTERY LED
- on: battery operation.
- blinking: battery reserve, or end of battery charge or negative battery test.
- off: mains operation.
- on in service mode: Autorestart on.
- off in service mode: Autorestart inhibited.
5 Red PROTECTION LED
- on: UPS operation blocked.
- flashing: failure of one or more power modules.
- alternating short-long flashing: incorrect connection of the input neutral conductor.
- off: normal operation.
- on in service mode: 60 Hz operation.
- off in service mode: 50 Hz operation.
6 Red OVERLOAD LED
- on: output voltage anomalies.
- flashing: overload.
- off: normal operation.
- brief flashes every 3 seconds: overload warning.
- on in service mode: load waiting mode (LWM) operation.
- off in service mode: normal operation.
7 Yellow BY-PASS LED
- on: by-pass active (output supplied directly from mains).
- off: output supplied by the inverter.
- on in service mode: Dip Speed switched on.
- off in service mode: Dip Speed switched off.
Acoustic signals:
• Continuous beep: UPS shutdown.
• Slow intermittent beep (one beep every 12 seconds): battery operation.
• Fast intermittent beep: overload or fault.
• Alternating short-long beep: autonomy reserve or negative battery test or incorrect connection
of neutral conductor.
• Single beep: indication of UPS switch-on or acknowledgement of battery test request or end of
battery test with positive outcome or start of service mode or end of service mode.
