• Max. medium temperature: 130 °C + adapter (150 °C)

• End-position signals

The actuator is available for the modulating controllers with the control Y signal. It is used with VS2, VM2, VB2, VMV and AVQM valves.

Installation

Disposal The actuator must be dismantled and the

elements sorted into various material groups before disposal.

Mechanical

The actuator should be mounted with the valve stem in either horizontal position or pointing upwards.

The actuator is fixed to the valve body by means of a mounting ring, which requires no tools for mounting. The ring should be tightened by hand.

Electrical

Important: It is strongly recommended that the mechanical installation is completed before the electrical installation.

Note: Two cable entries are provided for M 16×1.5 cable glands. One entry is provided with a rubber grommet. Note that in order to maintain the enclosure’s IP rating, appropriate cable glands must be used.

Commissioning

Complete the mechanical and electrical installation and perform the necessary checks and tests:

• Isolate control medium. (e.g. self-adjusting in a steam application without suitable mechanical isolation could cause a hazard).

• Apply the power. Note that the actuator will now perform the self-adjusting function.

• Apply the appropriate control signal and check the valve stem direction is correct for the application.

• Ensure that the actuator drives the valve over its full stroke, by applying the appropriate control signal. This action will set the valve stroke length.

The unit is now fully commissioned.

Commissioning / testing feature

The actuator can be driven to the fully open or closed positions (depending on valve type) by connecting SN to terminals 1 or 3.

Manual Override

The manual override is achieved by turning the manual knob to the required position. Observe the direction of rotation symbol.

If manual override has been used then X and Y signal are not correct until the actuator reaches its end position. If this is not accepted reset the actuator.

• Disconnect power supply

• Adjust valve position using control knob

• Set valve to closed position

• Restore power supply

The actuator has a selection of DIP switches under the removable cover. The switch provides the following functions:

DIP1: U/I - Input signal type selector:

• If set to OFF position, input signal Y is set to

voltage (Y).

If set to ON position, input signal Y is set to be

current (mA).

DIP2: 0/2 - Input signal range selector:

• If set to OFF position, the input signal is in the

range from 2 V to 10 V (voltage input) or from 4 mA to 20 mA (current input). If set to ON position, the input signal is in the range from 0 V to 10 V (voltage input) or from 0 mA to 20 mA (current input).

DIP3: D/I - Direct or inverse acting selector:

• If set to OFF position, the actuator is direct

acting (actuator’s stem extends by voltage increase). If actuator is set to ON position the actuator is inverse acting (actuator’s stem retracts by voltage increase).

DIP4: —/Seq - Normal or sequential mode

selector:

• 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) V … 5(6 V) / 5(6) V … 10 V).

NOTE: This combinatio n works in combination with D IP 5:

0(2)V… 5(6 V) / 5(6) V … 10 V

DIP5: 0-5 V/5-10 V - Input signal range in

sequential mode:

• This function is available if switch

DIP4:---/Sequential is set. Actuator can be set to match the range of the control signal:

2 … 6 V (DIP 2: 2 V … 10) 0 … 5 V (DIP 2: 0 V … 10) 4 … 12 mA (DIP 2: 2 V … 10) 0 … 10 mA (DIP 2: 0 … 10)

OR 6 … 10 V (DIP 2: 2 V … 10) 5 … 10 V (DIP 2: 0 V … 10) 12 … 20 mA (DIP 2: 2 V … 10) 10 … 20 mA (DIP 2: 0 … 10)

DIP6: Prop./3-pnt - Modulating or 3-point

mode selector:

Actuator can operate in modulating (DIP 6

to OFF) or in “simple” 3-point mode, if the 3-point function is selected (DIP 6 to ON).

Modulating mode; DIP 6 set to OFF

(factorysetting)

• 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.

• Actuator’s stem will run to its totally extended or retracted position by bridging SN signal to terminals 1 or 3 and will remain in this positron as long as potential is present.

It is not allowed to bridge SP to terminal 1

or 3 when DIP 6 is set to OFF .

3-point mode; DIP 6 set to On Look carefully wiring diagrams as wiring is

different for controllers with triacs output (ECL) in comparison to controllers with relay output.

• Connect SN (Neutral) and power supply (24Vac) via controller to terminals 1 or 3.

• Return signal X (depends on DIP 2, 3, 4 & 5) is possible if connected power supply to SP and SN.

SW7: LOG/LIN - Not in use.

SW8: 100 % KVS/Reduced KVS - Not in use.

SW9: Reset:

• Changing this switch position will cause the

actuator to go through a self-adjustment procedure.

Automatic self-adjustment feature

When power is first applied, the actuator will automatically adjust to the length of the valve stroke. Subsequently, the self-adjustment feature can be re-initialised by changing position of SW9.

Diagnostic LED

The red diagnostic LED is located on the pcb under the cover. It provides indication of three operational states:

• Actuator Healthy (Permanently ON),

• Self-adjusting (Flashes once per second),

• Error (Flashes 3 times per second - seek technical assistance).
