I. Auxiliary Contacts

In the unit there are two built-in programmable power relays (AUX1, AUX2). The potential-free change-over contact of this power relay is connected to the screw terminals (AUX1 NO-NC-COM, AUX2 NO-NC-COM)

Maximum Contact load: -230Vac / 5Amp-30Vdc/7Amp

In the factory we program this output to be active when one these situations are detected:

Over temperature

Overload

Over or under voltage of batteries

Unit is turned off manually or with a fault, “RUN/STOP” LED RED lit

over / under voltage of batteries. AC output overload.

over temperature.

J. The Remote control unit

As an option, a Remote control unit can be connected to the unit . All operating controls and displays are available on the Remote control unit, The Remote control is supplied with a 3m long cable. It can be lengthened to 15m The Remote control is suitable for surface mounting on the wall or on to a switch board. It is fixed with 2 screws. The unit can also be programmed with the Remote control. The output currents and the charging currents are displayed on the Remote control.

J.1 The Temperature sensor

Charging voltages of lead-acid batteries can change depending on temperature. To correct the operating voltages according to the actual temperatures, a temperature sensor can be connected to the unit .

The compensation through the sensor is -3mv//Cell.
