POSI: description
Various control types (control signal on terminals N°15 and N°16)
On request, our cards can be set in factory. The consign and the feedback signal can have different forms (current or voltage).
As standard, the cards are set for current 4-20mA (control + feedback signal).
Control in 0-10V modes:
In case of outside event, absence of control signal (accidental wires cut for example) but in presence of power, the actuator
will travel to defined position (open or closed valve).
As standard our actuators will close themselves in absence of control signal but there are other possibilities on request.
Control in 4-20mA mode:
In case of outside event, absence of control signal (accidental wires cut for example) but in presence of power, the actuator
will stay in its position.
POSI: electric connection
Actuator pre-set in factory.
In order to avoid electromagnetic perturbations, it is compulsory to use shielded cables (cables longer
than 3m).
SUPPLY AND CONTROL WIRING

Ensure that the voltage indicated on the actuator ID label corresponds to the voltage supply.

Connect the wires to the connector in accordance with the required control mode. (see diagram p. 28)
WIRING OF THE FEEDBACK SIGNAL
 Unscrew the right gland and pass the cable.
 Connect the input signal between terminals 15 and 16 (attached p.27 mark.B). Terminal 15 is the negative po-
larity (-) and terminal 16 is the positive polarity (+).
 Connect the output signal between terminals 13 and 14.(attached p.27 mark.C). Terminal 13 is the positive
polarity (+) and terminal 14 is the negative polarity (-).
 Tighten the cable gland (Ensure that it's well mounted to guaranty the proofness).
Factory setting : by default, 4-20 mA input and output signals with normal rotation sense.
To proceed to a new setting of the card : please see page 29, "Parameter selection sequence".
To check the proper operation of the card : please see page 29, "Normal operating mode".
HEATING SYSTEM WIRING
Power the terminals 10 and 11 (24 V, 110 V or 230 V according the version).
To ensure the correct functioning, the power supply (1, 2, 3, 4) and heating system terminals must be per-
manently powered.
In case of low temperature (< -20 °C), the actuator must be powered 3 hours before using (terminals 1-2-3-
4 and 10-11). This time is necessary for the enclosure to reach functioning temperature.
