Actuator ABNM A5 LOG/LIN
Description
The ABNM A5 0-10V thermal actuator has been
specifically designed for use with AB-QM valves
DN10-32/½-1¾ inch in heating and cooling
applications.
Actuator convincing features are:
• Stroke 5.0 mm or 6.5 mm
• Detection of AB-QM opening and closing
point
• Available as normally closed (NC) or normally
open (NO)
• Power consumption 1/1.2 W
• Plug-in halogen free cable
• Simple snap-on installation
• IP54 in any installation position
• First-Open function (NC versions)
• Compact size, small dimensions
• LIN and LOG versions
• 24V AC and DC versions
• All round function indicator
• Noiseless and maintenance-free
• Certified by TÜV
Control is done by a 0-10 V signal, which is
provided either by a room thermostat or, in most
cases, by a central direct digital control (DDC)
system. The actuator converts the 0-10 V signal
into a proportional actuator travel, which can be
either linear (ABNM A5 LIN) or logarithmic/equal
percentage (ABNM A5 LOG).
For fan coil unit or chilled ceiling application
choice of logarithmic version is recommended
(water to air heat exchanger). The result will be
linear system response and thus optimal room
temperature control.

Data sheet Actuator ABNM A5 LOG/LIN
Function The actuator mechanism of the ABNM actuator
uses a positive temperature coefficient (PTC)
resistor heated wax element and a compression
spring.
The wax element is heated by applying the
operating voltage and moves the integrated
piston. The force generated by this movement is
transferred to valve spindle and thus opening or
closing the valve. The actuator provides active
regulation in a defined range (see characteristic
curve between 0.5 V and 9.5 V).
The function display (all-round display) of the
ABNM shows at the first glance whether the
valve is “open” or “closed”.
First open function (for NC versions only)
In its delivery condition ABNM is partly open
due to the first open function (filling). This
enables heating/cooling operation during the
carcass construction phase even when the
electric wiring is not yet complete. During the
later electrical start-up, the first open function is
unlocked by applying the power supply for more
than 6 minutes.
Version NC “normally closed”
In case of the normally closed version, valve
is closed when de-energized. Valve is opened
steadily upon switching on the power supply,
setting control signal to 10 V and after expiry of
the dead time.
Power
ON
Function display for NC versions extends
proportionally with actuator opening from 0 mm
to 5-6 mm.
Version NO “normally open”
In case of the normally open version, valve is
open when de-energized. Valve is closed steadily
upon switching
on the power supply, setting control signal to 0 V
and after expiry of the dead time.
Automatic initial calibration
(for NC and NO versions)
Automatic initial calibration is done at the first
power on of the actuator (new actuator). If the
actuator is switched off within 8 hours after
the calibration is performed, each restart of the
actuator begins with a new initial calibration,
which last about 30 minutes. The power supply
needs to be applied for 30 min. (± 10 min.) in
order to finalize the calibration phase, which
includes valve opening and closing point
detection. This ensures an optimum match with
the AB-QM valve used at any preset between
20% and 100%. Active control range is thus
between 0.5 V and 9.5 V what ensures precise
flow and temperature control.
Automatic initial calibration stores calibration
parameters in the actuators non-volatile memory
after 8 hours. The information remains in the
actuators memory, also if actuator actuator
power supply is disconnected.
Manual re-calibration
(for NC and NO versions)
In case you change valve type or valve preset
after initial calibration is finished, apply 0 V
control voltage for 60 min. for closing point
detection and 10 V control voltage for 60 min. for
new opening point detection.
Please note the actuator stores this information in
non-volatile memory 8 hours after re-calibration.
If power is lost within 8 hours after re-calibration,
then this information is lost, and you need to
repeat the re-calibration procedure.
Automatic re-calibration
(for NC and NO versions)
In case you change valve type or valve preset
after initial calibration is finished and exact
timing of re-calibration is not important, manual
re-calibration procedure can be avoided.
Controller will during normal course of operation
sooner or later give control signal 0 V and 10 V.
Actuator will automatically detect new closing
point when control signal is 0 V for 60 min. and
new opening point when control signal is 10 V
for 60 min. We cannot guarantee duration of this
procedure, as it depends from control signal
from controller.

Operation after power-off
If power is lost within 8 hours after 8 calibration,
then you need to repeat re-calibration procedure.
