-24 V, 50 Hz/60 Hz

•Control input signal:

-0(4)-20 mA

-0(2)-10 V

•Force: 400 N

Installation	Mechanical
	No tool is required to mount actuator on the
	valve. Installation of the valve with the actuator
	is allowed in horizontal position or upwards.
	Installation downwards is not allowed.
	The actuator must not be installed in an
	explosive atmosphere, at ambient temperature
	lower than 0 °C or at ambient temperature
	higher than 55 °C. It must not be subject to
	steam jets, water jets or dripping liquid as well.
	Note:
	The actuator may be rotated up to 360° with
	respect to the valve stem by loosening the retaining
	fixture. Once the actuator is placed, retighten the
	fixture.
	Electrical
	Electrical connections can be accessed by
	removing the actuator cover. Two cable gland
	entries without thread (Ø16 and combined Ø16/
	Ø20) are prepared for cable glands. From factory
	one entry is provided by rubber cable gland and
	the other entry is prepared for opening.
	Note:
	Cable and cable gland used must not compromise
	the actuator’s IP rating, and must ensure the
	connectors are fully strain relieved.
	Rubber cable gland delivered from factory does not
	compromise IP rating but it does not provide fully
	strain relieve according to LVD directive.
	Please observe local rules and regulations as well.

Commissioning	Complete the mechanical and electrical
	installation, set jumper and DIP-switches, then
	perform the necessary checks and tests:
	• Apply power
	Note that the actuator will now perform
	automatic Calibrating function
	• Apply the appropriate control signal and
	check:
	- SW7 setting
	- the actuator drives the valve over the entire
	stroke length
	The unit is now fully commissioned.

Automatic Calibrating feature

The actuator automatically adapts its stroke to the valve end positions :

-when power is applied for the first time or

-afterwards by pressing the STAND BY/RESET button for 5 seconds

Testing entire valve stroke length

The actuator can be driven to the fully-open or closed positions by connecting SN to terminals 1 or 3.

Disposal	The actuator must be dismantled and the
	elements sorted into various material groups
	before disposal.

Jumper/DIP switch setting	Jumper
	• U/I - Input signal type selector
	- U position; voltage input is selected
	- I position; current input is selected
	Factory setting: jumper is in U position.
	DIP switches
	Factory setting: all switches are in OFF position.
	• SW 1: Not used
	• SW 2: Input signal range selector
	- OFF position; the input signal is in the range
	from 0-10 V (voltage input) or from 0-20 mA
	(current input)
	- ON position; the input signal is in the range
	from 2-10 V (voltage input) or from 4-20 mA
	(current input)
	• SW 3: Direct or Inverse acting selector
	- OFF position; the actuator is in direct acting
	mode (stem extracts as voltage increases)
	- ON position; the actuator is in inverse acting
	mode (stem retracts as voltage increases)
	If used with AB-QM valves, SW 3 is recommended
	to be in OFF position (factory setting).
	• SW 4: Fast/Slow - Speed selector
	- OFF position; the actuating speed is 7.5 s/mm
	- ON position; the actuating speed is 15 s/mm
	• SW 5: Not used

•SW 6: Not used

•SW 7: LOG/MDF - Logarithmic or modified flow through valve selector

-OFF position; .......... LOG (α=0.2, factory setting)

-ON position; ........... MDF (initial setting:

α=1, linear)

Explanation:

If SW 7 is in OFF position, alpha knob is not activated. Turning alpha knob will not influence α value (α=0.2).

If SW 7 is in ON position, α value can be manipulated using alpha knob. MDF initial setting of alpha knob is 1, which means linear setting. Regarding alpha knob setting see explanation below.

• SW 8: Not used

α-knob position	α-value

	1,000

Alpha knob found on PCB in MDF initial setting (linear, α=1)

Equal-percentage valve-flow adjustment

(SW 7 in position ON)

The actuator has a special valve-flow adjustment feature called alpha value. Actuator characteristics can be, by turning the alpha knob counter clockwise (CCW), variably-adjusted from α=1 (linear) to α=0.1.

In order to have optimal control, linear characteristics of system (valve, actuator, HEX) is required. This can be assured using the right α value. Appropriate α value depends on temperatures of heating/cooling medium and

controlled temperature of heated/cooled medium. Calculate α value according to the Tech Note number VNHUA102 (Setting the right α value).
