5. CONNECTIONS AND OPERATION
5.1. TERMINAL BOARD CN1
5.1.1. P
OWER SUPPLY
22V
Terminals “ VAC – VAC ”. Connect the transformer secondary circuit to this input with power supply of 24Vac 50/60 Hz.
Presence of power supplied by the transformer is signalled by the lighting up of the “ DL1 ” LED.
5.1.2. B
ATTERIES
Terminals “ +BAT – BAT ”. Connect the buffer batteries (optional) power cables to these terminals. The control unit is
designed to operate with two buffer batteries, with the minimum characteristics shown on the table of paragraph 2.
During normal operation, the control unit keeps the batteries charged. They enter into operation if no power is supplied
to the transformer .
Power supply from batteries only should be considered an emergency situation. The number of possible
manoeuvres is linked to the quality of the batteries, the structure of the gate to be moved, how long ago the
power cut occurred, etc, etc..
Observe the battery supply polarity.
