Safety Notes

To avoid injury of persons and

damages to the device, it is absolutely

necessary to read and observe these

instructions carefully.

Necessary assembly, start-up, and maintenance

work must be performed by qualified and

authorized personnel only.

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.

AC 24 V

Connect via safety isolating

transformer.

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

❶

The actuator should be mounted with the valve

stem in either horizontal position or pointing

upwards.

Installation

❷

•

Check the valve neck.

•

The actuator should be in steam up position

(factory setting) ①.

•

Ensure that the actuator is mounted securely

on the valve body ②, ③.

The actuator is fixed to the valve body by

means of a ribbed nut which requires no

tools for mounting. The ribbed nut should

be tightened by hand.

•

Wire the actuator according to the wiring

diagram ❸.

•

The direction of stem movement can be

observed on the position indicator ①.

Auto sleep mode

1. If actuator is not mounted to the valve but

connected to the power supply, it will first

run to its extracted end position (buzz noise

from the motor will appear). This behavior

will last for max 3 minutes when power

supply will be automatically cut off from

electro motor and LED indicators.

X: Indicates that this hazardous substance contained in at least one of the homogeneous material for this part is above the limit requirementw in GB/T 26572;

X: 表示该有害物质至少在该部件的某一均质材料中的含量超出GB/T 26572规定的限量要求。

2. It is mandatory to drive the spindle of the

actuator to upper position before it will be

installed on valve (please refer to manual

override drawings)!

3. Auto sleep mode switches back to learning

mode by pressing RESET button or by

cycling power supply.

Wiring

❸

Do not touch anything on the PCB!

Switch off the power line before wire

the actuator! Lethal voltage!

Wire the actuator according to the wiring

diagram.

DIP switch settings

Factory settings:

ALL switches (except SW 1 which is in ON

position) are in OFF position! ④

NOTE:

All combinations of DIP switches are allowed.

All functions that are selected are added

consecutively.

SW 1: 0/2 - Input signal range selector

If set to OFF position, the input signal is in

the range from 2-10 V (voltage input) or from

4-20 mA (current input).

If set to ON position, the input signal is in the

range from 0-10 V (voltage input) or from 0-20

mA (current input).

SW 2 : D/I - Direct or inverse acting selector

If set to OFF position, the actuator is direct

acting (stem lowers as voltage increases).

If the actuator is set to ON position, the

actuator is inverse acting (stem raises as voltage

increases).

SW 3: ---/Seq - Normal or sequential mode

selector

If set to OFF position, the actuator is working in

range 0(2)-10 V or 0(4)-20 mA.

If set to ON position, the actuator is working in

sequential range; 0(2)-5(6) V or (0(4)-10(12)mA)

or (5(6)-10 V) or (10(12)-20 mA).

SW 4: 0-5 V/5-10 V - Input signal range in

sequential mode

If set to OFF position, the actuator is working in

sequential range 0(2)-5(6) V or 0(4)-10(12) mA.

If set to ON position, the actuator is working in

sequential range; 5(6)-10 V or 10(12)-20 mA.

SW 5: LIN/MOD - Linear or modified flow

through the VZL valves

If set to ON position, the flow through the

LINEAR characterized VZL valve will modify to

equal percentage-wise equals the control signal.

If set to OFF position, the flow through the valve

VZ or VZL remains same as is valve characteristic

in accordance to the control signal.

SW 6: ---/ASTK - Anti-blocking function

Exercises the valve to avoid blocking in periods

when the heating/cooling is off.

If set to ON position (ASTK), the valve motion is

switched on. The actuator opens and closes the

valve every 7 days.

If set to OFF position (---), the function is

disabled.

SW 7: U/I - Input signal type selector

If set to OFF position, voltage input is selected.

If set to ON position, current input is selected

Reset button

❹③

Press the reset button will cause the actuator to

go through a self stroking cycle (press it for 2 s).

Manual override

❺

Do not manually operate the drive

if power is connected!

Do not dismount the actuator

from the valve when it is in a stem down

position!

If dismounted in a stem down position, there is a

high risk that the actuator gets stuck.

Remove cover ①

Press and hold the button (on the bottom

side of the actuator) ② during manual

override ③

Replace cover ④

Install actuator on valve ⑤, ⑥

Remark:

A 'click' sound after energising the actuator

indicates that the gear wheel has jumped into

normal position.
