Operating and installation instructions

Electronic positioner ES11

6.1 Factory setting

Upon delivery of the ES11 with a cpl. control device (valve and actuator), the potentiometer
and the ES11 are adjusted by factory to it’s valve travel. The factory setting is indicated with
a waterproof marker or a sticker on the nameplate.

If the order was given without indication of a special control signal, the default is 4-20mA.
4mA for a closed valve.

6.2 Setting of potentiometer

a) To adjust the potentiometer in the actuator, the operating instructions of the

corresponding actuator have to be observed.

b) Switch-off mains voltage and secure against unintentional reconnection.
c) Turn the potentiometer to 0 Ohm position.

- At PREMIO-actuator turn the potentiometer spindle counter-clockwise until it stops

(0 Ohm position).

- For inspection, the resistance of the potentiometer must be measured with an

ohmmeter.

For resistance measurement disconnect the potentiometer from the ES11 positioner.

First measurement contact ................R

B

- grey cable...... - PREMIO terminal 26 (29)

Second measurement contact ...........R

C

- red cable........ - PREMIO terminal 25 (28)

With completely extended actuator spindle, it must be approx. 0 Ohm between the first
and second measuring contact.

d) Turn thrust actuator with manual handwheel into cpl. retracted position and read the

corresponding resistance value at the Ohmmeter.

- With cpl. retracted actuator stem, 750th...1100 Ohm must lie between the first and

second measuring contact.

e) Connect the potentiometer with the ES11 positioner again.

6.3 Type of control signal

The selection of the required control signal, is done by
corresponding clamp connection.

Type of control signal

clamp connection at:

Voltage signal

max. 10 V DC for e.g. 0-10V

YU and GND

Current signal

max. 20mA DC for e.g. 4-20mA

YI and GND

It may be only one control signal connected.

6.4 Setting of effective direction SW

At the switch SW, the effective direction of the control
signal is adjusted to the thrust direction.

Take the switch to the desired position.
