These connections are routed from the main terminal boards on the
1639187
board according tables below. For
correct wiring you should note the following:
1.
All input and output signals refer to a nominal voltage of 24Vdc.
2.
The outputs on terminal board CN8 refer to voltage indicated as Vio on terminal 1 and 2 of CN11.
3.
The framework is provided with (Vio) power supply input coinciding with (Vint) internal power supply via
bridges on the terminals: CN.3 with CN11.1, CN2.4 with CN11.2.
The inputs are provided galvanic isolated.
4.
Outputs equipped with galvanic insulator; If you want to enter with active signals whose 24V alimentation
is taken outside the framework is necessary to remove the connections on CN11.1 and CN11.2. In this
case is also necessary carry this power to CN11.1 and CN11.2. in according to polarity.
5.
The connections for dual line commands on CN4 are configured for 24Vdc changeover valve. If it the
changeover solenoid use different power supply, remove connections on terminal CN4.3 and CN4.4 and
connect the appropriate voltage.
6.
Connections on terminal CN10 are SPDT type clean contacts.
