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 ❶

Wiring ❷

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.

DH-SMT/SI

AME 335, AME 435

Functions accessible from cover

RESET ❸

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 ❹

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 ❺

Jumper ①: 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 ④

SW 5: Not used

SW 6: Not used

SW 7: LIN/MDF - Linear or modified flow

characteristic ❻

VI.LE.J1.3B

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 ❼

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.

Dismounting ❽
