safety Note
To avoid injury and damage to persons
and devices, it is absolutely necessary
these instructions are carefully read
and observed prior to assembly and
commissioning.
Necessary assembly, start-up, and
maintenance work must be performed
only by qualified, trained and authorised
personnel.
Prior to assembly and maintenance work
on the controller, the system must be:
- depressurised
- cooled down
- emptied
- cleaned
Please comply with the instructions of the
system manufacturer or system operator.
Do not remove the cover before the power
supply is fully switched off.
Disposal instruction
This product should be
dismantled and its
components sorted, if
possible, in various groups
before recycling or disposal.
Always follow the local disposal
regulations.
AC 24 V
Connect via safety isolating transformer.
Mounting ❶
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 ribbed nut which requires no
tools for mounting. The ribbed nut should
be tightened by hand.

Wiring ❷
Do not touch anything on the PCB!
Switch off the power line before wiring the
actuator! Lethal voltage!
Wire the actuator according to the wiring
diagram.
Auto sleep mode
1. If actuator AME 110 NL is charged 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 ❸
1. Check the valve neck. The actuator
should be in stem up position (factory
setting). Ensure that the actuator is
mounted securely on the valve body
2. Wire the actuator according to the
wiring diagram.
3 The direction of stem movement
can be observed on the position
indicator ❸①.
DIp switch settings and
reset button ❹
1) DIp switches ❹④
Factory settings:
ALL switches (except SW 2 which is in ON
position) are in OFF position!
NOTE:
All combinations of DIP switches are allowed.
All functions that are selected are added
consecutively.
sW 1: U/I - Input signal type selector
If set to OFF position, voltage input is
selected. If set to ON position, current
input is selected.
sW 2: 0/2 - Input signal range
selector
If set to OFF position, the input signal is in
the range from 2-10 V (voltage input) or
from 4-20 mA (current input). If set to ON
position, the input signal is in the range
from 0-10 V (voltage input) or from
0-20 mA (current input).

sW 3 : D/I - Direct or inverse acting
selector
If set to OFF position, the actuator is
direct acting (stem contracts as voltage
increases). If the actuator is set to ON
position, the actuator is inverse acting
(stem extracts as voltage increases).
sW 4: ---/seq - Normal or sequential
mode selector
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).
sW 5: 0 ... 5 V/5 ... 10 V - Input signal
range in sequential mode
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.
sW 6: LIN/Log - Linear or equal
percentage flow through valve
selector
If set to ON position, the flow through the
valve is equal percentage to the control
signal.
If set to OFF position, the valve position is
linear acc. to the control signal.
sW 7: ---/AsTk - Anti-blocking
function
Exercises the valve to avoid blocking in
periods when the heating/cooling is off.
If set to ON position (ASTK), the valve
motion is switched on. The actuator opens
and closes the valve every 7 days.
If set to OFF position (---), function is
disabled.
sW 8: reset
Changing this switch position will cause
the actuator to go through a self stroking
cycle.
NOTE:
The reset switch must be in OFF position to
make reset button function active ( press it
for 2 sec. ) see ❹ ③ .
2) reset button ❹③
The reset button on PCB has the same
function as the reset switch SW 8.
