Control panel

"I/O" button 26 .

Provides access to On/Off controls.

This button is active only on remote,

master "Tele Monitor" units.

"*" button 27 .

This button has a number of functions

depending on the displayed messages

(confirmation, positive response, etc.).

Pressing this button followed

immediately by the "V" button 21 (less

than one second) provides access to

the display configuration function. In

"Monitor" multi-cubicles mode, this

button can also be used to display the

type of cubicle concerned by the

displayed message. The information

disappears when the button is

released. For example:

CUBICLE NUMBER 1 =

STATIC SWITCH MODULE

"W.Hz" button 23 .

Provides access to measurements:

◗ Mains 1 and 2 and inverter

frequency;

◗ active and apparent power drawn by

the load;

◗ load power factor.

"Battery" button 24 .

Provides access to battery

measurements:

◗ battery voltage (or DC voltage for

frequency converters without a battery);

◗ battery current (charge or discharge);

◗ battery temperature (optional);

◗ remaining battery time.

"Alarms" button 25 .

Displays current or logged alarms and

stops the buzzer for the "Tele Monitor"

option.

A blinking character ("!", "A" or "kW") at

the end of the line indicates that the

user must press the "alarms" 25 ,

"A" 22 or "W.Hz" 23 button

respectively to display the remaining

alarms or further information.

◗ local operation. The "Monitor"

alphanumeric display (see figure 34)

may be installed behind the hinged

cover of the hidden panel (see figure

25) on the control panel in all types of

cubicles (UPS or Static Switch

Cubicle).

special enclosure, the "Tele Monitor"

provides the user with remote

indications on system status. Two "Tele

Monitor" units may be connected to the

same system, one as a master for

indications and remote control, the

other as a slave for indications only.

The "Monitor" can operate in two

different modes:

◗ mono-cubicle: the option monitors

only the cubicle in which it is installed;

◗ multi-cubicle: "Monitor" can monitor

all system cubicles (up to eight

maximum). In this mode, the system is

equipped with only one "Monitor" which

may be installed in any of the cubicles.

"Settings" button 19 .

This button can be used to select the

display language, adjust screen

contrast to local conditions and, for the

"Tele Monitor" option, adjust the

volume level of the buzzer.

"V" button 21 .

Provides access to voltage

measurements:

◗ Mains 1 phase-to-phase voltages;

◗ Mains 2 phase-to-neutral and phase-

to-phase voltages;

◗ inverter output phase-to-neutral and

phase-to-phase voltages;

◗ load phase-to-neutral and phase-to-

phase voltages.

"A" button 22 .

Provides access to current

measurements:

◗ currents on the Mains 1 and 2 lines

and the load;

◗ percent current drawn by the load;

◗ percent load with regards to the

rated value;

◗ load current peak factor.
