AME 658 SU/ SD – with safety function

Motorized actuators for AB-QM™ valves

Description

The actuators AME 658 series are designed to regulate the AB-QM valve in applications involving heating and chiller applications.

The available options include input signals of modulating or 3-point oating and actuators that have a safety function in either spring open or close during a power failure.

Main data:

• 24V AC/DC powered actuators

• Control input signal: modulating or 3-point

• Selectable actuator speed

• Max. medium temperature: 392 °F (200 °C )

Features:

• Manual operation either mechanical and/or electrical

• Output signal

• Visible LED feedback operation

• Selectable stem travel speed

• Inverse functionality

• Self calibration of acuator stem travel

• Integrated external switch

• Characteristic optimization

• Stem travel limitation

• Pulse or continuous output signal

• Voltage or current input signal Y

• Voltage or current output signal X

• External reset button

• Auto detection of Y signal

• X and Y galvanic insulation

• Thermic and overload protection

Commissioning

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

Complete the mechanical and electrical installation (see instructions) and perform the necessary checks and tests:

- Power the actuator

- Set the appropriate control signal and check that the valve stem direction is correct for the application.

The unit is now fully commissioned.

Design

Installation Mechanical

The allowable orientation of the actuator can be installed in all positions. Allow for necessary clearance for maintainance and for the mounting of the actuator to the valve. A M8 socket to mount the actuator to the valve and a 4mm Allen key to link the valve stem to the actuator.

1. Manual operation knob

2. Function buttons

3. Panel cover

4. Removable gland support

5. Position indication ring

6. Stem connector

7. Valve connector

Electrical

Electrical connections can be accessed by removing the service cover. Four cable entries are available (Two M16 x 1.5 and two M20 x 1.5) Note in order to maintain the enclosure IP rating, appropriate electrical nuts must be used.
