DESCRIPTION
Normal operation with mains present
and loads within the set limits
The UPS is indicating that the output
voltage frequency is not synchronised
with the input voltage. The cause of this
may be:
- PLL disabled
- Frequency of the input voltage is
outside the set limits for the UPS
Battery operation
By-Pass operation
UPS failure
ATTENTION! WE RECOMMEND YOU
SWITCH OFF THE UPS AND CONTACT

Controls:
The UPS is managed by means of the button on the front panel, illustrated in figure 1 in the diagram
on page 11.
1
On / Off Button:
- Press briefly to switch the UPS on: confirmation is given by the momentary lighting up of all the Status
Indicator's and by a short acoustic signal (beep).
- Keep the same button pressed for longer than 2 seconds to switch the UPS off, confirmed by the
intermittent beeping of the buzzer.
Warning:
• In normal operating conditions, the green Status Indicator is lit.
• During operation with battery power, the yellow Status Indicator is lit.
• The UPS indicates it is operating with battery power by emitting a slow acoustic sound (one beep every
20seconds). 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 red Status Indicator. The end of battery autonomy is signalled by the
flashing of the red Status Indicator 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 Status Indicator 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
operation of the UPS will be blocked after 15 seconds of continuous overload. If the red Status Indicator
(4) flashes with a rapid intermittence, it signals a fault in the UPS; if the intermittence is alternating short-
long, it signals an anomaly in the connection of the UPS (wrong connection of neutral conductor). 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.
Connection
The UPS has a standard RS232 interface and it is possible to use this, in conjunction with a computer, to
access a series of data regarding the operation and the history of the UPS. The function can be used by
means of the UPS Communicator interface programme for Windows and Linux(*) environments, by connecting
a serial port on the PC to the interface socket [7] located on the rear of the UPS using a RS 232 cable.
It is also possible to configure the UPS, enabling or disabling the special functions (Software).
UPS DIAGNOSTIC SOFTWARE
It is possible to download a free copy of a software for Windows and Linux environments (16 and 32 bit)
and/or to
get a detalied list of the supported systems visit our internet website
www.metasystem.it
This software offers the following functions:
- Display of all the operating and diagnostics data in case of problems.
- Configuration of the special functions.
- Automatic shutdown of the local computer (with Windows operating system).
Windows is a registered brand of Microsoft Corporation.
BATTERY TEST
The battery test can be done during UPS operation on mains power as follows:
1. Automatically: after programming by means of the optional shutdown software
2. Every time the UPS is switched on (by means of the software).
The test is done with the UPS operating on mains power (that is without forcing the operation of the UPS onto
battery power) thanks to a particular MetaSystem patented circuit: therefore even if the battery test gives a
negative result, there will be no interruption of the output power.
