Actuator for modulating control AME 435 QM

Description

AME

435 QM actuator for modulating control is used with pressure independent balancing and control valve type AB-QM from DN 40 to DN 100.

The actuator has some special features:

•

it automatically adapts its stroke to the valve end positions which reduces commissioning time

• valve ow adjustment feature; ow can be variably-adjusted from linear to logarithmic or opposite.

• the advanced design incorporates load related ‘switch-o’ to ensure that actuators and valves are not exposed to overload

Main data:

• Nominal voltage (AC or DC):

- 24 V, 50 Hz/60 Hz

• Control input signal:

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 xture. Once the actuator is placed, retighten the xture.

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 Automatic Calibrating feature

Complete the mechanical and electrical installation, set jumper and DIP-switches, then perform the necessary checks and tests:

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

- when power is applied for the rst time or

• Apply power Note that the actuator will now perform

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

automatic Calibrating function

Testing entire valve stroke length

• Apply the appropriate control signal and check:

- SW7 setting

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

- the actuator drives the valve over the entire

stroke length

The unit is now fully commissioned.

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 modied ow 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 inuence 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

SMT/ SI

Equal-percentage valve-ow adjustment

(SW 7 in position ON)

The actuator has a special valve-ow 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).
