Actuator 2 point, ON/OFF control AMI 120 NL-1
Description
The AMI 120 NL-1 is a 2 point (ON/ OFF), 3 wire actuator used with the AB-QM pressure independent control valves installed on hot or
chilled water system applications. This actuator is installed on AB-QM valve sizes ranging from 1/2” to 1- 1/4”. The AB-QM assembly is suitable for
installation within fan coil units, VAV, induction units or additional units that require combined balancing and valve control, which could be located within enclosures or plenum rated spaces.
As a 3 wire actuator, it receives constant power to travel to its default position and upon receipt of input signal will travel in the opposite direction. Designed within the actuator is an overload and gap function to prevent unnecessary travel from the actuator.
Main data:
•2-point, ON/ OFF, 3 wires required
•Force switch-off at stem down position prevents overload of actuator and valve
•Gap function detection on stem up travel
•No tools required for mounting
•Maintenance free during lifetime
•Low noise operation
•1/2” Conduit hole, removable plate
•Wiring terminal block
•In accordance with UL 2043 for plenum installation
•UL listed

Actuator for two point control AMI 140 |
Installation |
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.
Electrical
Important: Prior to energizing the actuator should be assembled to the AB-QM.

Jumper Position “A” (Factory Setting)
“On” at terminal block position “1”: Actuator drives down and valve closes, optional terminal 4 closes.
“Off” at terminal block position “1”: Actuator drives up and valve opens, optional terminal 5 closes.
Jumper Position “B”
“On” at terminal block position “1”: Actuator drives up and valve opens, optional terminal 4 closes.
“Off” at terminal block position “1”: Actuator drives down and valve closes, optional terminal 5 closes.
Disposal |
The actuator must be dismantled and the |
|
elements sorted into various material groups |
|
before disposal. |
|
|
Commissioning |
The factory position of the actuator spindle is in a |
|
full stem up position allowing easier mechanical |
|
connection of the actuator on the valve. |
