Danfoss Heating VI.LE.F2.3O DH-SMT/SI

ENGLISH

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 controller, 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 actuator

Fix the AME 438 SU on the valve. ❶

Admissible Installation Positions. ❷

Dimensions ❸

Wiring ❹①

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.

Control signal

Control signal from the controller must be

connected to terminals Y (input signal) and

SN (common) on the AME printed board.

Output signal

Output signal from the terminal X can be

used for indication of the current position.

Range depends on the DIP switch settings.

Supply voltage

(24 V~ -15 to +10%, 50 Hz) must be

connected to the terminals SN and SP.

DIP switch settings ❺

Factory settings:

ALL switches are on OFF position!

Note:

All combinations of DIP switches are

allowed. All functions that are selected are

added consecutively. There is only one logic

override of functionalities i.e. the switch No.6

Proportional / 3 point, which sets actuator to

ignore control signal and works as a “simple”

3-point actuator.

SW1: U/I ❺①

Factory setting:

voltage control signal (0-10 V).

SW2: 2-10 V / 0-10 V ❺②

Factory setting is:

2-10V.

SW3: Direct/Inverse ❺③

Factory setting is:

DIRECT

SW4:---/Sequential ❺④

Two actuators can be set to work parallel

with one control signal. If the SEQUENTIAL

is set than an actuator responds to split

control signal (see 0(2)-5(6)V/5(6)-10V).

Note:

This combination works in combination with

switch No.5: 0(2)-5(6)V/5(6)-10V

SW5: 0(2)-5(6)V/5(6)-10V ❺⑤

Note:

This function is available if switch No.4:

--- / Sequential is set.

SW6: Proportional/3 point ❺⑥

Actuator can operate as “simple” 3-point

actuator, if the 3-point function is selected.

Power supply should be connected on SN

and SP ports ❹②. On port 1 or 3 24 VAC

signal is connected for rising or lowering

of actuator. Return signal X indicates the

correct position.

Note:

if 3 point function is selected actuator does

not respond to any control signal on port Y.

It only rises and lowers spindle if power is

supplied on port 1 or 3.

SW7: LOG. ﬂow/LIN. ﬂow ❺⑦

Factory setting is:

LOG. Flow (characteristic of valve is

unchanged)

Note:

If this function is used in combination with

non-logarithmic valves the characteristic

of motorised valve will be anti-logarithm of

valve’s characteristic (e.g. valve with linear

characteristic will be transformed to quick

open characteristic).

SW8: 100% K

/RED. K

❺⑧

Note:

This function works properly only with

logarithmic (equal percentage) valves.

SW9: Reset ❺⑨

After the actuator has been connected

to power supply, the actuator will start

the self-adjustment procedure. The

indicator LED ﬂashes until self adjustment

is ﬁnished. The duration depends on the

spindle travel and will normally last a few

minutes. The stroke length of the valve is

stored in the memory after self adjustment

has been completed. To restart self

adjustment, change the position of RESET

switch (switch No.9). If the supply voltage

is switched oﬀ or falls below 80% in more

than 0.1 s, the current valve position will be

stored in the memory and all data remain

saved in the memory also after a power

supply cut-out.
