Actuators for modulating control AME 25, AME 35

Description

AME electric actuators are used with, VRB, VRG, VF, VL valves with additional adapter (Code No. 065Z0311, not supplied) and VFS valves up to DN 50 diameter.

The actuator automatically adapts its stroke to valve end positions which reduces commissioning time.

The actuator has some special features:

•The advanced design incorporates load related ‘switch-off’ to ensure that actuators and valves are not exposed to overload;

•The advanced design incorporates a diagnostic LED, operational data capture and self stroking feature;

•Low weight and robust.

-24 Vac, 50 Hz/60 Hz

•Control input signal:

Actuators for modulating control AME 25, AME 35

Installation

Tmax≤150°C for AME 25, 35

Tmax≤150°C for AME 25, 35

and VRB, VRG, VF and VL

and VFS

Tmax = 200°C for AME 25, 35 and VFS

Adapter for VFS (Code No.065Z7548)

≈5o ≈5o

Mechanical

Use 4 mm Allan key (not part of actuator delivery) 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 with thread (M20 x 1.5 and M16 x 1.5) are prepared for cable glands.

Note: Cable and cable gland used must not compromise the actuator’s IP rating, and must ensure the connectors are fully strain relieved. Please observe local rules and regulations as well.

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

The actuator has a function selection DIP switch under the removable cover. In particular, if SW6 is set to ON, the actuator will perform as 3-point actuator.

The switch provides the following functions:

• SW1: U/I - Input signal type selector:

If set to OFF position, voltage input is selected. If set to ON position, current input is selected.

•SW2: 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).

•SW3: D/I - Direct or inverse acting selector:

If set to OFF position, the actuator is direct acting (stem lowers as voltage increases). If actuator is set to ON position the actuator is inverse acting (stem raises as voltage increases).

•SW4: —/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).

• SW5: 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.

• SW6: Prop./3-pnt - Modulating or 3-point mode selector:

If set to OFF position, the actuator is working normally according to control signal. If set to ON position, the actuator is working as 3-point actuator.

For this operation please refer to page 4 (wiring 3-point control).

When DIP switch SW6 is set to ON than all functions from other DIP switch become inactive.

• SW7: LOG/LIN - Equal percentage or linear flow through valve selector 1):

If set to OFF position, the flow through valve is equal percentage. If set to ON position, the

flow through valve is linear according to control signal.

• SW8: 100% KVS/Reduced KVS - Flow reduction through valve selector 1):

If set to OFF position, the flow through valve is not reduced. If set to ON position, the flow through valve is reduced by half of increment between standard KVS values. Example: valve

with KVS 16 and SW8 set to ON – maximum flow through the valve is KVS 13 (middle between standard KVS 16 and next lower standard KVS 10).

1) NOTE: To be used only in combination with valves with equal percentage characteristic.

• SW9: Reset:

Changing this switch position will cause the actuator to go through a self stroking cycle.
