switch / LED main function
1
‘UPS off’ switch switches the UPS from normal operation to bypass and from
bypass or battery to standby.
2
‘UPS on’ switch switches on the UPS, starts quick battery test (see section 4.5),
mutes the buzzer.
3
LED ‘mains available’ (green) indicates availability of power mains.
4
LED ‘battery’ (yellow) on in case of battery operation: the mains power fails, and the
internal batteries supply the required power until either they are
depleted or mains power returns.
5
LED ‘operation’ (green) on when the output is supplied by the UPS (inverter).
6
LED ‘bypass’ (yellow) on when the UPS operates in bypass mode: the incoming mains
power is channeled directly to the load. Blinks if the input voltage
is out of bypass tolerance (see section 4.4.4 for more details).
7
LED ‘alarm’ (red) on in case of alarm.
8
LED bar ‘runtime capacity’ the remaining available battery runtime for the actual load, in % of
the maximum runtime with the actual load. When the alarm LED
is on, this bar may show a combination of LEDs, describing the
Alarm cause (see 4.4).
1º LED: 0-20% green
2º LED: 21-40% green
3º LED: 41-60% green
4º LED: 61-80% green
5º LED: 81-100% green
9
LED bar ‘load’ indicates to what extent the output capacity of the UPS is used
by the actual load. If e.g. the 25% and 50% LED are on, the load
exceeds 26% of the maximum load. If all 5 LEDs are on the unit
operates in overload. As this is an abnormal situation the alarm
LED will be on as well.
1º LED: 0-20% green
2º LED: 26-50% green
3º LED: 51-75% green
4º LED: 76-100% green
5º LED: >100% yellow
