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).
Without any information from the customer, 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).
In standard our actuators will close themselves in absence of control signal but there are other possibilities on re-
quest.
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.
In the both cases, when the control signal is restored, the actuator reach automatically the position corresponding to
control signal value.
Positioning card wiring (set-point and feedback signal
Actuator pre-set in factory.
In order to avoid electromagnetic perturbations, it is compulsory to use shielded cables (cables longer than 3m).
 Unscrew the right gland and pass the cable.
 Connect the input signal between terminals 15 and 16 (attached p.36 mark.B)..
 Terminal 15 is the negative polarity (-) and terminal 16 is the positive polarity (+).
 Connect the output signal between terminals 13 and 14.(attached p.36 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).
The feedback must be connect with rigid wires. If the applied voltage is higher than 42V, the user must fore-
see a fuse in the power supply line.
Factory setting : by default, 4-20mA input and output signals with normal rotation sense.
To proceed to a new setting of the card : please see page 41, "Parameter selection sequence".
To check the proper operation of the card : please see page 41, "Normal operating mode".
