V81608A Ist.Uso Whad2000:V81608A Ist.Uso UPS Whad2000
• Yellow BATTERY LED
• On fixed: battery operation
• Flashing: battery reserve level, or end of autonomy, or negative battery test.
• Off: mains operation.
• Red ALARM LED
• On fixed: UPS operation is blocked.
• Flashing: fault in one power module.
• Alternating short-long flashing: wrong connection of neutral, input conductor (if neutral sensor is enabled).
• Off: normal operation
• On fixed: anomaly in output voltage
• Flashing: overload
• Off: normal operation
• Short flashing every 3 sec: warning of imminent overload
• Yellow BYPASS LED
• On fixed: bypass in operation (output supplied directly by mains)
• Off: output supplied by inverter.
Acoustic signals:
• Continuous sound: UPS operation is blocked.
• Slow intermittent sound (one beep every 12 seconds): battery operation.
• Fast intermittent sound: overload or fault.
• Alternating, slow-fast intermittent sound: autonomy reserve, or negative battery test, or wrong connection of
neutral, input conductor (if neutral sensor is enabled).
• Single beep: signals switching on of UPS, or recognition of request for battery test, or end of battery test
with positive result.
Controls:
The UPS is managed by means of the button on the front panel, illustrated in the diagram on page 12.
1 On / Off Button:
- Press briefly to switch the UPS on: confirmation is given by the momentary lighting up of LED [2] and by a
short acoustic signal (beep).
- Keep the same button pressed for approximately 2 seconds to switch the UPS off, confirmed by the inter-
mittent beeping of the buzzer.
Warning:
• In normal operating conditions, the green MAINS LED [2] is lit.
• During operation with battery power, the yellow BATTERY LED [2] is lit.
• The UPS indicates it is operating with battery power by emitting a slow acoustic sound (one beep every 12
seconds). Battery reserve, i.e. the opportune moment for the user to shut down the open procedures on the
computer connected to the UPS, is indicated by an alternating, slow-fast intermittent sound together with
the corresponding flashing of the yellow BATTERY LED [2]. The end of battery autonomy is signalled by the
flashing of the yellow BATTERY LED and the continuous sounding of the buzzer for a total length of 15": in
this state, the load is no longer supplied.
• The red ALARM LED flashes to indicate the presence of an excessive load on the output.
In this case, if mains is present, the load is supplied through the bypass with mains power, otherwise the ope-
ration of the UPS will be blocked after 15 seconds of continuous overload. If the red ALARM LED [2] flashes
with a rapid intermittence it signals a fault in one or more of the power modules; if the intermittence is al-
ternating short-long it signals an anomaly in the connection of the UPS (wrong connection of neutral con-
ductor). If the neutral is wrong invert the plug on the UPS power supply cable.
• In all cases, when the operation of the UPS is blocked due to any anomaly, it completely and automatically
shuts down after approximately 15 seconds.
