Commissioning

2

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.

LED signalling / actuator
operating modes

LED operating mode indicator

The two LED’s located on the actuator cover
provides three dierent color feedback (green/
yellow/red). Based upon the color and if they ash,
will indicate dierent operating situations.

RESET button

The external RESET button is located on the top
cover of the actuator next to LED indicators.
Pressing this button once will enter or exit the
Stand-By mode. For the AME series of actuators
holding the button for 5 secs will initiate the
calibration mode.

Operating modes

• Stand-By mode
The actuator stops in current position and
does not react to the control signal. In this
mode the actuator can be manual operated
via mechanical handle or control buttons.
To exit Stand-By mode the RESET button is
pressed again.

• Calibration mode
The actuator will enter this mode when it
is powered for the rst time or if the Reset
Button is pressed down for 5 secs. During
calibration the actuator will determine the
full travel of the valve. When calibration is
completed the actuator will be in normal
operation responding to the control signal.
