AME 25SU
AME25SD
The AME 25 series of low voltage electronic
actuators are proportionally controlled and
internally incorporate a safety spring function.
In the event of power loss, the actuator will
return to either a normally open or normally
closed position depending on the style selected
(spring up-SU or spring down-SD). These series
of actuators are mounted to ABQM valves in
sizes of 1-½” to 4” valves.

Installation
Orientation:
Manual Override:
Dimensions:
The actuator should be mounted with the valve stem either horizontal or pointing
upwards. Use a 4 mm Allen key (not supplied) to fit the actuator to the valve body.
Allow necessary clearance for maintenance purposes. During commissioning, the
movement of the actuator (e.g. opens for heat) can be indicated by fitting red and blue
pins (supplied) at either end of the position indication scale.
On spring versions manual override is achieved
by disconnecting the power supply, removing
the cover and inserting a 5 mm Allen key (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. Another alternative to correct
this is to reset the actuator.

Electrical Wiring:
Wiring for proportional control
Wiring for 3-point floating control
Automatic self stroking feature
When power is first applied, the actuator
will automatically adjust to the length of
the valve stroke. Subsequently, the self
stroking feature can be reset by pressing
the reset button once (located under the
cover).

Proportional DIP
switch setting
The actuator has a function selection
DIP switch under the removable cover.
In particular, if SW6 is set to ON, the
actuator will perform as 3-point
actuator.
The switch provides the following functions:
• SW1: U/I - Input signal type selector:
If set to OFF position, voltage input is selected.
Ifset to ON position, current input is selected.
• SW2: 0/2 - Input signal range selector:
If set to OFF position, the input signal is in the
range from 2 V to 10 V (voltage input) or from 4
mA to 20 mA (current input). If set to ON
position, the input signal is in the range from 0
to 10 V (voltage input) or from 0 mA to 20 mA
(current input).
• SW3: D/I - Direct or Reverse acting selector:
If set to OFF position, the actuator is direct
acting (stem lowers as voltage increases). If
actuator is set to ON position the actuator is
reverse acting (stem raises as voltage increases).
• SW4: —/Seq - Input signal range in
sequential mode:
If set to OFF position, the actuator is working in
range 0(2)…10 V or 0(4)…20 mA. If set to ON
position, the actuator is working in sequential
range; 0(2)…5 (6) V or (0(4)…10 (12) mA) or
(5(6)…10 V) or (10(12)…20 mA).
• SW5: 0…5V/5…10V - Normal or sequential mode
selector:
If set to OFF position, the actuator is working in
sequential range 0(2)…5 (6) V or 0(4)…10 (12) mA.
If set to ON position, the actuator is working in
sequential range; 5(6)…10 V or 10(12)…20 mA.
• SW6: Prop./3-pnt - Modulating or 3-point
mode selector:
If set to OFF position, the actuator is working
normally according to control signal. If set to ON
position, the actuator is working as 3-point actuator.
• SW7: LOG/LIN - Equal percentage or linear fl ow
through valve selector :
If set to OFF position, the fl ow through valve is equal
percentage. If set to ON position, the he fl ow
through valve is linear according to control signal.
• SW8: 100% C
through valve selector:
Leave in the OFF position (not required when in
combination with AB-QM).
• SW9: Reset:
Changing this switch position will cause the actuator
to go through a self stroking cycle.
