Logic Signal And Remote Control Interface - Meta System HF TOP LINE 910 Bedienungsanleitung

Controls:
The UPS is controlled using the two buttons on the front panel, as seen in the figure on page 6.
1 On/Off button:
- Press to switch on the UPS. This is confirmed by a short illumination of all the LEDs and a
brief acoustic signal (beep).
- Keep the button pressed for about two seconds to switch off the UPS, indicated by the
intermittent beep of the buzzer.
2 Buzzer stop/battery test button:
- Press this button briefly to silence the buzzer. This annuls the acoustic warning in progress
and the buzzer remains silent until it is necessary to signal another event.
- Keep this button pressed for about two seconds make a battery test request; for further
details refer to the relative section of the manual.
Please Note:
• Under normal operating conditions, the green MAINS LED [3] and INVERTER LED [8] are on.
• During battery operation, the green INVERTER LED [8] and yellow BATTERY LED [4] are on.
• Battery operation is indicated by a slow beep (one beep every 12 seconds). Autonomy reserve,
i.e. when shutdown of procedures on the computer connected to the UPS must start , is
indicated by an intermittent alternating short-long beep accompanied by similar flashing of the
BATTERY LED [4].
• End of battery charge is indicated for 15 sec. before the yellow "BATTERY" led begins to flash
along with a continuos sound from the buzzer.
• Flashing of the red OVERLOAD LED [6] indicates an excessive output load. In this event, if
mains is present, the load is supplied by mains through the by-pass; otherwise, the UPS shuts
down after 15 seconds of continuous overload.
• Flashing of the red PROTECTION LED [5] if the intermittence is quick, this indicates the failure
of one or more power modules, or if the intermittence is alternating short-long, an anomaly in
the UPS connection (incorrect neutral conductor connection). In the case of incorrect neutral,
invert the phase and neutral wires in the I/O connector or reverse the UPS power cable plug.
• When the UPS shuts down due to any anomaly, it is automatically and completely switched off
after about 15 seconds.

LOGIC SIGNAL AND REMOTE CONTROL INTERFACE

On the back of the UPS unit there are two, identical and interchangeable 9-pin sockets [13],
which enable the operational remote control and/or transmission of logic signals to computers
equipped with special hardware and software. The logic signals are electrically insulated from
the rest of the UPS and indicate whether the unit is operating on mains or battery and whether
the batteries are in reserve. Normally, these signals are used for informing the operator of the
status of the UPS so that he can close any procedure in progress before the autonomy of the
UPS runs out, thus preventing data loss. In fact, with certain operating systems it is necessary
to give special commands to the computer before being able to switch it off safely; the autonomy
reserve signal can be used to manage these procedures automatically.
