safety note

To avoid injury and damage to persons
and devices, it is absolutely necessary
these instructions are carefully read
and observed prior to assembly and
commissioning.

Necessary assembly, start-up, and
maintenance work must be performed
only by qualified, trained and authorised
personnel.

Prior to assembly and maintenance work
on the actuator, the system must be:

- depressurised
- cooled down
- emptied
- cleaned

Please comply with the instructions of the
system manufacturer or system operator.

Do not remove the cover
before the power supply is fully
switched off.

Disposal instruction

This product should be
dismantled and its
components sorted, if
possible, in various groups
before recycling or disposal.

Always follow the local disposal
regulations.

Mounting and installation

Wiring

Do not touch anything on the PCB!
Switch off the power line before wiring
the actuator! Lethal voltage!
Wire the actuator according to the wiring
diagram.

Functions accessible from cover

REsET
By pushing STAND BY/RESET button for
5 sec. the actuator starts self stroking
procedure to adjust to the stroke of the
valve to which it is connected.
Procedure starts with extracting the stem.
As the maximum force is detected
the actuator reverse its direction until
maximum force in opposite direction is
detected.
During calibration Bi-Color LED blinks
green 1/sec. After reaching fully upper end
position actuator enter normal mode and
start catching Y control signal.

Manual override

nOTE:

If manual override has been used then
control and return signal are not correct until
the actuator reaches its end position.

DIP switch settings

Jumper : U/I - Input signal type selector

DIP switches

Factory settings:
ALL switches are in OFF position!

nOTE:

All combinations of DIP switches are allowed.
All functions that are selected are added
consecutively.

sW 1: Not used

sW 2: 0/2 - Input signal range selector ②

sW 3: D/I - Direct or inverse acting
selector ③

sW 4: Fast/Slow: Speed selector

sW 5: Not used

sW 6: Not used

sW 7: LIN/MDF - Linear or modified flow
characteristic ❻

sW 8: Smart function selector
If set on OFF position the actuator does
not try to detect any oscillations in the
system. If set on ON position actuator
enables special anti oscillations algorithm.

lED function indicator

Green – initialization (RESET), set-point
position, transition indicator
Red - indicates STAND BY and Failure
mode.
Green:
• Flashing light (once every 6 sec.) ②

- actuator reached set-point acc. to Y

signal

• No light

- no operation or no power supply

• Flashing light (~ 1Hz) ③

- self adjusting mode.

Red:
• No light

- no operation or no power supply

• Constant light ④

- fault condition occurred

• Flashing light (2 Hz) ①

- STAND BY
- power supply too low
- initial self-adjusting time too short

due to too short valve strokes

- failure during self calibration.
