1. Product Description.
The electro-pneumatic positioner is used for rotating operation of valves with pneumatic
actuators by means of an electric controller or a control system with an analogical output
signal of 4 –20 mA.
It can be used with double effect or single effect actuators. Easy setting of zero and of the
trajectory. Easy switching of direction (clockwise / counter-clockwise).
Low air consumption and easy connection to air ducts.

3. Security Instructions
The goal of this manual is to allow users with technical skills to install, turn on, operate
and inspect Genebre’s electro-pneumatic positioners. Qualified personnel must be
familiar with all notices and warnings described in these instructions. Not complying with
these notices and warnings may cause serious personal injury and material damages.
Certain parts of the positioner are subject to mechanical movement
which may cause injury.
Work on the system or electric equipment must only be performed by
qualified technicians or by trained personnel under the control and
monitoring of said technicians, according to the security rules and
guidelines, as well as other applicable national laws.
Negligent use may cause serious damage to the parts, installation and
people, as well as to the equipment itself. Under no circumstance can
any part or component of the positioner be modified or altered. Such
alterations or modifications automatically invalidate the designed use
of the positioner.

4. Transport and Storage Conditions
•The positioners are shipped from the Genebre, S.A. headquarters in
appropriate packaging to prevent damage.
•Any slings, ropes or chains used to lift or transport motorized valves must NOT
be attached to the positioner under any circumstances.
•The positioner’s supports are designed to withstand the action efforts but NOT
the total weight of the valve, or any other type of burden or effort.
•Do NOT bang the positioner against walls, floors or other machines. That could
cause severe damage to the positioner or its parts.
•Store in a dry and well-ventilated place, safe from bad weather conditions.
Avoid placing them straight on the floor. Use pallets, shelves o wood bases.
•Genebre, S.A. recommends to visually examine the possible damages suffered
during transportation and storage. Visual inspection must include the interior of
compartments.
5. Preliminary Checks
•Verify that the characteristics of the positioner match those required before
proceeding to install and turn on the device. That data can be found in the data
plate.
•Should there be any deviation or non-conformance, please contact Genebre, S.A.
•Maximum pressure of air supply 7 kgf/cm² (100 psi)
6. Positioner Installation
6.1 Installation of the Support and the Positioner on the actuator
•Connection to the fixing of the output shaft in which the position of the
positioner’s output shaft and the main shaft of the rotating actuator are
concentric. Type C connection (see figure) is Namur, direct connection to the
actuator.
Make sure the supply air to be used is Dry, Clean and Filtered, since
bad quality supply air may seriously damage the positioner.

•The positioner’s support is designed to be mounted on actuators with a shaft
height of H=20 or H=30, as well as fixing holes at 80 mm or 130 mm according
to Namur regulations.
6.2 Mounting of the Cam
Note: The positioner leaves the factory with the cam mounted on the shaft and the
indicator plate in the position “RA” (counter-clockwise/reverse acting).
In case you need to switch the direction (clockwise/direct acting) proceed as follows:
•Lift the cover of the positioner.
•Remove the clamping screw from the indicator plate and remove the plate.
•Remove the clamping nut from the cam.
•Remove the cam and turn with the side marked as “DA” facing up.
•Mount the cam on the ledge of the output shaft.
•Set the actuator on the initial position.
Attention: Do not supply air to the equipment during this operation. It
may be highly dangerous.

•Fix the cam using the upper nut so that the reference line “0” is tangent to the
bearing.
•Once the cam is mounted, place and fix the indicator plate to the main shaft using
the M3 screw so that the reference lines for the cam and the indicator match up.
6.3 Air Connection.
Attention: Make sure the supply air to be used is Dry, Clean and
Filtered.

1. Use a regulator with a filter to constantly maintain the supply air pressure
(optimum supply pressure of 6 bar to operate the actuator).
2. Purge the air circuit completely to avoid strange particles.
3. In applications with single effect actuator (spring return) close output OUT1 or
OUT2 as appropriate.
6.4 Electrical Connection (transmission signal).
Connect the power-supply terminals (+) and (-) to input terminals (+) and (-) of the
positioner or transmitter, accordingly.

For the Output wiring instruction art. 5951 06 you should consult the technical data sheet of
the limit switch box art. 5987.

8. Starting Up (Settings)
Note: The positioner leaves the factory set to position 0º and path 90º. In case you
need to establish these settings, proceed as follows.
8.1 Zero Setting
•Send a run start signal (4 mA).
•Turn the ZERO setting wheel clockwise or counter-clockwise until the reference
lines of the indicator cam and the tangent point of the bearing match.

•In the case of the single effect actuator, check that it is set to zero point at
standard pressure. Otherwise, repeat Zero Setting.
8.2 Span Setting
•Set the span so that the actuator stops at position 0% in the run with an input
signal of 0% (4 mA), and so that it stops at position 100% with an input signal of
100% (20 mA), respectively.
•Check Zero point and repeat the Span setting as many times as required.
•Once the equipment is set, tighten the Locking screw.
8.3 Auto / Manual Switch
This switch is used to switch between Auto and Manual modes. The equipment leaves
the factory in Auto mode. To switch to Manual mode, turn the A/M regulator counter-
clockwise.
In Manual mode, the network pressure connects directly to the actuator. Return to Auto
mode after using.
This option does not apply to the single effect actuator connected to output OUT2.
