Actuator for modulating & 3-point control

AME 685 – without safety function

Description

The actuator is designed to control the valve in response to the demand of a controller in District Heating/cooling, Heating, Ventilating and Air conditioning systems.

The AME 685 can be controlled by electronic controllers with modulating or 3-point control output.

Actuator can be used in combination with: Valve type VF 3 (DN 200-300)

Features:

•

Manual operation mechanical and/or electrical

• Position indication, LED signalization

• Selectable speed 2,7 or 6 s/mm

• Automatic adaptation of stroke to valve’s end positions that reduces commissioning time (self stroking)

• Integrated auxiliary switch

• Characteristic optimization

• Adjustable stroke limitation

• Anti-oscillation function

• Pulse or continuous output signal (4 & 5)

• Voltage or current output signal X

• External reset button

• Auto detection of Y signal

• 3-point or modulating control selection

• Galvanic insulation Y & X and output terminal (4 & 5)

• Thermal and overload protection

• Precise control and fast response in 3-point mode (0,01 s)

Main data:

• Nominal voltage (AC or DC ):

- 24 V, 50 Hz/60 Hz

- 230 V, 50 Hz/60 Hz

• Control input signal: modulating or 3-point

• Force: 5000 N

• Stroke: 80 mm

• Speed (selectable): 2,7 or 6 s/mm

• Max. medium temperature: 200 °C

Disposal Before disassembly please contact Danfoss

The actuator must be dismantled and the elements sorted into various material groups

support for disassembly instructions.

before disposal.

Commissioning

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

- Turn on the power

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

The unit is now fully commissioned.

Installation

Wiring

Do not touch anything on the PCB! Do not remove the ser vice cover before the power supply is fully switched off.

Max. allowed current output on terminals 4 and 5 is 4A . Min. power is 3W.

Recommended cross-sectional area of the wiring is 1.5 mm

Mechanical

Please check the allowed installation positions for the valve and actuator. The actuator can be installed in following positions (see below).

DIP 6 OFF (1a, 1b) DIP 6 ON (2a, 2b)

Use hook spanner NH10 key (not supplied) to fit the actuator to the valve body. Allow for necessary clearance for maintenance purposes. To link valve and actuator stems use a 20 mm wrench key and 5 mm Allen key (not supplied).

The actuator has position indication rings which should be pushed together before electrical connection; after self-stroking they indicate end positions of the stroke.

Electrical connection

Electrical connections can be accessed by removing the service cover.

Four cable entries on removable gland support are provided for M 16×1,5 or M 20×1,5 cable glands. Note that in order to maintain the enclosure’s IP rating, appropriate cable glands must be used.
