Control operation

Spring return facility

Control

Manual control

The electronics module converts the positioning signal to a phase-cut power signal
which generates a magnetic field in the coil. This causes the armature to change its
position in accordance with the interacting forces (magnetic field, counterspring,
hydraulics). The armature responds rapidly to any change in signal, transferring the
corresponding movement directly to the valve plug, enabling fast changes in load to be
corrected quickly and accurately.
The valve’s position is measured continuously (inductive). The internal positioning
controller balances any disturbance in the system rapidly and delivers the position
feedback signal. The valve stroke is proportional to the positioning signal.

If the positioning signal is interrupted, or in the event of a power failure, the valve’s
return spring will automatically close control path A → AB.

The magnetic actuator can be driven by a Siemens controller or a controller of other
manufacture that deliver a DC 0/2...10 V or DC 4... 20 mA output signal.
To achieve optimum control performance, it is recommended to use a 4-wire
connection.

MANUAL

The valve control path (ports A → AB) can be opened

OFF

manually to between 80 and 90 % of the full stroke
(depending on DN) by pressing the hand wheel

AUTO

inwards and turning it clockwise (MANUAL setting).
This disables the control signal from the controller, the

MANUAL

green LED is flashing.

OFF

4455Z03

To disable automatic control of the valve, press the
hand wheel inwards and turn it anti-clockwise (to the
OFF position). The valve will close, the green LED is
flashing.

AUTO

For automatic control, the hand wheel must be set to
the AUTO position (the hand wheel will spring out),
the green LED is lit.

When commissioning the valves, however,
(especially under extreme conditions of use) there
may still be some leakage via control path A → AB
with a 0 % stroke control signal (DC 0 V, DC 2 V or
DC 4 mA).
In this case, the valve can be recalibrated simply
and quickly:

1. Hand wheel [2] in AUTO-position

2. Use a pointed implement (ø 2 mm) to operate the

button in the opening [3] once

3. While recalibration is in progress, the LED [5] is

flashing green for approximately 10 seconds.
The valve will be briefly closed and fully opened.

If the electronics module is replaced, the valve’s
electronics must be recalibrated. For that, the hand
wheel must be set to AUTO.

The valves and actuators are maintenance-free.

The low friction and robust design make regular servicing unnecessary and ensure a
long service life.
The valve stem is sealed from external influences by a maintenance-free gland.

Repair

Caution

Caution

If the valve electronics prove faulty, the electronics module must be replaced by the
ASE1 (DN15…32) or ASE2 (DN40…65) replacement electronics module.
Mounting instructions no. 35678 are included.

Always disconnect power before fitting or removing the electronics module.

After replacing the electronics module, calibration must be triggered in order to
optimally match the electronics to the valve (refer to "Calibration", page 5).

Under

operating conditions within the limits defined by the application data, the
actuator will become hot, but this does not represent a burn risk. Always
maintain the minimum clearance specified, refer to "Dimensions", page 12.

Disposal

Do not dispose of the actuator in domestic waste. This applies in particular to the PCB.

The law may demand special handling of certain components, or it may make
environmental sense.

Observer all current local laws.

Observe all application-specific technical data.
