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.
