Electrical actuator AME 855

Description

Actuator AME 855 can be controlled by electronic controllers with modulating or 3-point control output.

Actuator can be used with VF3 valves (DN 200-300).

Features:

• 3-point or modulating control Easy to use manual operation ( monitoring on

• terminal R)

• Position indication

• LED signaling

• Direct or inverse function

• Automatic adaptation of stroke to valve’s end positions which reduces commissioning time

• Voltage or current input Y

• Voltage or current output X (for current output, accessory is needed)

• Frost protection function (for detailed information read the Functions section in the data sheet)

• Blockage detection

• Internal temperature control – integrated heater + overheat protection

• Wire break detection (only modulating actuator)

• Selectable hysteresis

• Auto test function

• Auto pause function

• Potential-free position switches (accessory)

• Remote reset possibility

Main data:

Nominal voltage:

•

- 24 V AC

- 115 V or 230 V AC

• Control input signal: 3-point or modulating

Actuator is primarily designed to regulate valve in the respond to the demand of a controller in District Heating/cooling, Heating, Ventilation and Air conditioning systems.

Disposal

Commissioning

Installation

The actuator must be dismantled and the elements sorted into various material groups before disposal. Before disassembly please contact Danfoss support for disassembly instructions.

Complete the mechanical and electrical

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

• Turn on the power

• Press initialization button (INIT)

• Set the appropriate control signal and check the valve stem direction is correct for the application

7 mm

Mechanical

Please check what are allowed installation positions for the valve in combination. Use appropriate 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 appropriate key (not supplied). The actuator has position indication rings which should be pushed together before el. connection; after self-stroking they indicate end positions of the stroke.

Electrical

Electrical connections can be accessed by removing the cover. Four cable entries on removable gland support are provided for M 16×1,5 cable glands. Note that in order to maintain the enclosure IP rating, appropriate cable glands must be used.

Return signal during “manual” mode

• R= 24 V DC max. 35 mA

Zero potential of signals X, Y and R

• When the zero potentials of signals X, Y and R are identical to the zero potential of the supply voltage it is possible to bridge terminals N1 and N2 (230V only).

• If you run the actuator in continuous mode at 230 V you will have to

connect N2.

• If you run the actuator in three-point mode at 230 V you will have to

connect N2 if you wish to use X or R at the same time.
