Danfoss AME 110 NLX Actuators for Modulating Control User Guide
Safety Note
To avoid injury of persons and damages to the device, it is absolutely necessary to read and observe these instructions carefully.
Necessary assembly, start-up, and maintenance work must be performed by qualified and authorized personnel only.
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.
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
-
If actuator AME 110 NLX is charged by 24 V supply voltage and if it is not installed on ABQM valve, it will stop in lower position and switch off all LED indicators after 5 minutes
-
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)! -
Auto sleep mode switches back to learning mode by pressing RESET button or by cycling power supply.
Installation ❸
- 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
- Wire the actuator according to the wiring diagram.
- The direction of stem movement can be observed on the position indicator ❸①.
DIP switch settings and reset button ❹
- DIP switches ❹④
SW 1: 0/2 – Input signal range selector
If set to OFF position, the input signal is in therange 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 2 : 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 3: —/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 4: 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 5: 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 6: —/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 7: U/I – Input signal type selector
If set to OFF position, voltage input is selected. If set to ON position,
current input is selected.
Reset button ❹③
The reset button will cause the actuator to go
through a self stroking cycle (press it for 2 s).
Manual override ❺
(for service purposes only)
Do not manually operate the drive if
power is connected!
- Remove cover ❺①
- Press and hold the button (on the bottom side of the actuator) ❺② during manual override ❺③
- Replace cover ❺④
- Install actuator on valve ❺⑤
Remark:
A ‘click’ sound after energising the actuator indicates that the gear wheel
has jumped into normal position.
Function test
The light emitting diodes (LEDs)
❹① (green – direction indicator),
❹② (red – reset and normal mode indicator) indicate whether the actuator is in
operation or not, the operating status, and failures, if any.
Red LED:
-
No light
– no operation or no power supply -
Constant light
– normal operation -
Flashing light (1 Hz)
– self-adjusting mode -
Flashing light (~ 3 Hz):
– power supply too low
– initial self-adjusting time too short due to too short valve strokes
– failure during self calibration
Green LED:
- Spindle extracts (green led diode blinking once per sec.)
- Spindle retracting (green LED on)
- Actuator reached set-point acc. to Y signal (LED off).
