User manual
COMPACT V4.0 E
19
Caution: No external voltage should be connected to this Input Control.
4.11 The Temperature sensor
Operating voltage of lead-acid batteries change depends on the
temperature. To correct the operating voltages according to the actual
temperatures, a temperature sensor can be connected to the COMPACT.
The compensation through the sensor is –3mV/°C/Cell.
Order Number: CT-35
Dimensions: H x B x T / 58 x 51.5 x 22mm
5 Programming

5.1.3 Auxiliary
contact
Active in case of defect or manual turn off with the LED 10/11/12/13
5.2 Reset
value
When the COMPACT is to be connected to a battery or after an interruption (RESET), it is always
programmed with these standard settings.
In order to get to these settings during operation you must press the three Push Buttons 19/20/21
simultaneously for a minimum of 2 seconds.
5.3 Battery voltages and absorption time
The voltage levels (low voltage, float charge, end of charge and equalization) and the duration of
the absorption charge can be changed.
The display of these voltages and the times in the program mode are in accordance with the
diagram shown below:
