Actuator for two point control
DH-SMT/SI VD.KH.B1.02 © Danfoss 03/2008 1
Description AMI 140 is 2 point 3 wires actuator used with
AB-QM (DN 10-32) and VZ, VZL, VRBZ valves.
The actuator can be used with fan coil units,
induction units, small re-heaters, re-coolers and
zone applications in which hot/cold water is the
controlled medium. The actuator provides with
factory default setting (actuators spindle fully
stem up):
- normally closed function for AB-QM and
- normally open function for VZ, VZL, and VRBZ
Note: it is possible to change setting from normally closed
to normally open function (see “Wiring” part jumper
setting, page 2.

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: It is strongly recommended that the
mechanical installation is completed before the
electrical installation.
Each actuator is supplied with the connecting
cable for the controller.
Wiring
AMI 140 - 230VAMI 140 - 24V
Commissioning The factory setting of the spindle is the fully
stem up position because of easier mechanical
connection of the actuator on the valve.
Disposal The actuator must be dismantled and the
elements sorted into various material groups
before disposal.

Actuator for two point control AMI 140
a) Check the valve’s neck. The actuator should
be in steam up position (factory setting) .
Ensure that the actuator is mounted securely
on the valve body.
b) Energise the actuator according to the wiring
diagram - see page 2.
c) The direction of stem movement can be
observed on the position indicator .
Installation and
commissioning procedure
(if required)
Manual override
(for service purposes only)
1. Remove the cover.
2. Insert the Allen key 6 into the spindle.
3. Press and hold the button (on the bottom side
of the actuator) during manual override.
4. Pull out the tool.
5. Place cover back on the actuator.
Do not touch anything on
the PCB! Before removing
the cover in need of hand
operation with Allen key
power supply must be
disconnected.
Lethal voltage!
Caution:
Do not manually operate the
drive under power! Remark:
A ”click” sound after energizing the actuator
means that the gear wheel has jumped into
normal position.
