Actuators for modulating control
AME 120 NLX-1 - with position feedback signal
Description
Ordering
The actuator receives a modulating 0(2)-10VDC
or 0(4)-20mA signal to provide precise control.
The profile of the actuator assembly is ideal in
fan coil units, induction units, small reheaters,
recoolers and zone applications in which hot/
chilled water is the controlled medium.
Main data:
• Position feedback or output signal
(X=0-10 VDC)
• Gap detection at stem up position
• Modulating control
• Force switch-off at stem down position
prevents overload of actuator and valve.
• No tools required for mounting
• Maintenance-free lifetime
• Last state position. Detection of missing
The AME 120NLX-1 is a compact gear motor
actuator that is assembled to ½” to 1-¼” AB-QM
valves sizes.

Installation Mechanical
The actuator should be mounted with the valve
stem in either horizontal position or pointing
upwards.
Installation of the actuator assembly is certified
for placement within the plenum airspace.
Electrical
Important: Prior to energizing the actuator
should be assembled to the AB-QM.
Auto sleep mode
1. If actuator AME 120 NLX-1 is powered by 24 V
supply voltage and if it is not installed on
AB-QM valve, it will stop in lower position and
switch off all LED indicators after 5 minutes.
2. It is mandatory to drive the spindle of the
actuator to upper position before it will be
installed on AB-QM valve (please refer to
manual override drawings)!
3. Auto sleep mode switches back to learning
mode by pressing RESET button or by cycling
power supply.
Installation procedure
Wiring
1. Check the valve neck. The actuator should be
in the full up position (factory setting). If it is
not, manually reposition the actuator to its
full up position.
2. The actuator is fixed to the valve body by
means of a ribbed nut which requires no tools
for mounting. The ribbed nut should be hand
tightened only.
3. For applications requiring conduit, a field
supplied 1/2” trade size electrician’s fitting
and lock nut can mounted in the actuator
enclosure. Make all wiring connections in
accordance with local, national, or regional
regulations.
4. Insert wiring material through the removable
plug or conduit fitting, and connect to
the terminal block according to the wiring
diagram.
