Environment information

Standard information Media Contacts 9

Terminals XR1, XR2, XR3 and XR4 on the remote transmission board of each type of unit can be used for the input of data from the operating environment and for the transmission of signals on the operational status of the device (see figures 18, 19, 20 and 22 for the position of the board).

Signal reception

The signals should be provided by volt- free contacts.

emergency shutdown. An NC contact causes:

rapid shutdown of the inverter and the RC,

opening of battery circuit breaker QF1,

transfer of the load to Mains 2 (generally without interruption in the supply of power);

battery room ventilation fault:

a NO contact causes the shutdown of the RC;

battery circuit breaker QF1 closed: a NO contact inhibits inverter start-up when the breaker is open;

battery temperature: an optional PC-board may be connected to the remote transmission board. It supplies information on the battery temperature, thus enabling the RC to regulate the battery voltage.

Note:

The Static Switch Cubicle does not receive any of the above signals.

Signal transmission

an auxiliary 24V power supply, isolated and backed up, is used to supply:

the undervoltage coil release for the battery circuit breaker(s) QF1,

an optional board that measures the temperature in the battery room;

"general alarm" information

(2 volt-free changeover contacts) which includes:

internal faults,

information on temperatures outside tolerances in the battery room (optional),

overload information (I > In),

static switch ventilation and power- supply faults;

"low battery shutdown" warning signal (2 volt-free changeover contacts) indicating that battery time is about to run out. The warning threshold may be personalized;

"load on inverter" signal (2 volt- free changeover contacts) indicating that the load is supplied by the inverter. In single-unit UPS systems, one volt- free changeover contact may be used to indicate that the load is supplied by Mains 2;

"load on battery" signal (2 volt-free changeover contacts) indicating that the inverter is supplied by the battery in the following cases:

Mains 1 outage or voltage drop,

RC shutdown,

RC current limiting;

This signal, which may be used to initiate process saving and shutdown procedures, is time-delayed by 30 seconds to avoid unnecessary operations following micro-breaks;

"maintenance position" signal (2 volt-free changeover contacts) indicating that;

maintenance bypass switch Q3BP is closed,

Mains 2 input switch Q4S is open,

inverter output switch Q5N is open,

battery circuit breaker QF1 is open;

signal to open battery circuit breaker(s) QF1 in the event the "emergency shutdown" button being pressed or to avoid an excessive battery discharge (more than 3 rated time).

Note:

the maximum breaking capacity of

the changeover contacts is 5A at 250V;

information on the battery is not supplied to frequency converters without a battery or to the Static Switch Cubicle;

in systems with a Static Switch Cubicle, the "load on inverter" and "maintenance position" signals must be directed to the Static Switch Cubicle.
