Actuators for modulating control

AME 13SU, AME 23SU - safety function (spring up)

Description

AME 13SU AME 23SU

Ordering

The actuators with safety function are mainly used with VZ valve (AME 13SU) or with VS, VM and VB valves (AME 13SU, AME 23SU). Safety version is activated automatically in case of power failure or if the power supply is switched off by the safety thermostat.

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-adjusting feature;

• Low weight and robust;

• Safety function (spring up).

Safety function The safety function will fully open or close the

valve when the power is removed, depending upon the spring action selected. Valve selection will also affect the spring action. The safety function unit is factory fitted to the rear of the actuator.

Installation

AME 13 SU

AME 23 SU

Disposal

Mechanical

The actuator should be mounted with the valve stem in either horizontal position or pointing upwards.

The actuator is fixed to the valve body by means of a mounting ring, which requires no tools for mounting. The ring should be tightened by hand.

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

Electrical

Important: It is strongly recommended that the mechanical installation is completed before the electrical installation.

Note: Two cable entries are provided for M 16×1.5 cable glands. One entry is provided with a rubber grommet. Note that in order to maintain the enclosure’s IP rating, appropriate cable glands must be used.

Commissioning Commissioning/testing feature

Complete the mechanical and electrical installation and perform the necessary checks and tests:

The actuator can be driven to the fully open or closed positions (depending on valve type) by connecting SN to terminals 1 or 3.

- Isolate control medium. (e.g. self-adjusting in a steam application without suitable mechanical isolation could cause a hazard).

- Apply the power. Note that the actuator will now perform the self-adjusting function.

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

- Ensure that the actuator drives the valve over its full stroke, by applying the appropriate control signal. This action will set the valve stroke length.

The unit is now fully commissioned.

Manual override

AME 13 SU AME 23 SU

On spring versions manual override is achieved by disconnecting the power supply, removing the cover and inserting a 6 mm Allen key for AME 13 SU, a 5 mm Allen key for AME 23 SU (not supplied) into the top of the positioning spindle and turning the key against the spring. Observe the direction of rotation symbol. To hold a manual override position, the key must be wedged.

If manual override has been used then X and Y signal are not correct until the actuator reaches its end position. If this is not accepted reset the actuator.

Automatic self-adjustment feature

When power is first applied, the actuator will automatically adjust to the length of the valve stroke. Subsequently, the self-adjustment feature can be re-initialised by changing position of SW9.

Diagnostic LED

The red diagnostic LED is located on the pcb under the cover. It provides indication of three operational states:

• Actuator Healthy (Permanently ON),

• Self Stroking (Flashes once per second),
