Posi (Gp5) Models - VALPES VRX Manual De Instalación Y Funcionamiento

POSI (GP5) : 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 0-10 V or 0-20 mA 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 4-20 mA 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.
The caps placed on M20x1.5 openings (appendix p.44 mark 16) must be replaced by metallic ATEX and IP68
certified cable glands. The unused threaded opening must be closed with ATEX and IP68 certified caps.
Power supply wiring

Ensure that the voltage indicated on the actuator ID label corresponds to the voltage supply.

Unscrew the left cable gland and insert the cable.

Remove 25mm of the cable sheath and strip each wire by 8mm.

Connect the wires to the terminal strip in accordance with the diagram p. 44.

Tighten the ATEX & IP68 cable gland (Ensure that it's well mounted to guaranty the proofness).
Setpoint and feedback wiring

Unscrew the right gland and pass the cable.

Connect the input signal between terminals 15 and 16 (attached p.43 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.43 mark.C). Terminal 13 is the positive polarity (+) and
terminal 14 is the negative polarity (-).

Tighten the ATEX & IP68 cable gland (Ensure that it's well mounted to guaranty the proofness).
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 45, "Parameter selection sequence".
To check the proper operation of the card : please see page 45, "Normal operating mode".
In order to avoid electromagnetic perturbations, it's mandatory to use shielded cables (cables longer than
3m).
The control voltage must be S.E.L.V. (Safety Extra Low Voltage).
No common earth/ground connexion between the control (input and output signal) and the alimentation.
(Type 0-20 or 4-20mA : 5V DC max.)
10 kOhm input impedance if control with voltage (0-10 V) and 100 Ohm input impedance if control with cur-
rent (0-20 mA or 4-20 mA)
The card resolution is 1°
