Please consult our General
Conditions of Supply.

Important Information

≠ Electrostatic discharges caused by touching the

printed circuit boards can cause the destruction
of individual components. Please take
appropriate precautions antistatic workplaces,
metallic connections to a water pipe, etc.

≠ In order to obtain the required protection

against physical contacts in accordance to DIN/
EN 60355-@, the external cable installation has
to be duly isolated and protected against
physical contacts.

Warnings:

≠ Any work done on the actuator may only be

carried out by authorized and trained person­nel.

≠ These products are according to the Machine

Guidelines 98/37/EG (ancient 89/392/EWG), not
regarded as machines; they are, however, built
into installations which are regarded as machines.

Note

We distinctly emphasize that operation is
prohibited until it has been confirmed that the
machine (plant) into which the products have
been built corresponds to the conditions of the
EC Machine Guidelines 98/37/EG (ancient
89/392/EWG).

Controller Type PE 22 for instal­lation in electric actuators
EA 20/EA 30 and EA 4@/EA 50

1. General Features

Electrically powered valves are increasingly being
driven by external reference inputs.

With the PE 22 Controller, the EA 20, EA 30, EA 4@
and EA 50 electric actuators can be employed as
follows:
≠ as a continuously adjustable positioner from

0. . .90° or 0. . .180°; in the process the aperture
angle of the valve is measured continuously and
compared with the setpoint

≠ as a process controller in conjunction with an

external sensor and a reference input.

The PE 22 Controller comprises two parts (PEV 22/
PEV @22 and PER 22) and is preferably installed in
the actuator in the factory; it can, however, also
be supplied in kit form (Fig. @).

8.2 Installing the internal potentiometer for
actual value feedback

Important: Ensure that during installation (with

valve closed) the potentiometer is at the left-hand
stop when viewed from above (turn counter-clock­wise), i.e. the resistance between the red and
white wires must be 0 Ohm.
(See EA 20/EA 30/EA 41/EA 50 Instruction
Manual).

9. Adjustments

9.@ Used as positioner with internal potentio­meter

Potentiometers P@ and P2 (Fig. @0) must be turned
clockwise as far as the stop (max. 28 revs.).
This is already set in the factory.

The regulating speed of the valve can be adjusted
between 7 and @5 s by means of potentiometer P3.

The controller thus displays a predominantly pro­portional action.

Three potentiometers are provided on the control
unit (PER 22) for special adjustments:
P@ for adjusting reset time
P2 for adjusting the proportional range
P3 for delaying the setpoint (remains at left-hand
stop)

If the setscrew is turned counter-clockwise:
≠ the reset time is shortened (I component is

increased)

≠ the proportional range is diminished (P compon-

ent is reduced)
