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.
Mounting
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
** 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 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
- 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
- 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
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 ❹③.
2) Reset button ❹③
The reset button on PCB has the same function as the reset switch SW 8.
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).
