Safety Note

To avoid injury of persons and damage 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 a 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.
** Donor touches and piling 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 NI. is charged by 24 V supply voltage and W it is not installed on AB-QM valve, it will stop in a lower position and switch off all LED indicators after S minutes
2. It is mandatory to drive the spindle of the actuator to the upper position before it will be installed on the AB-QM valve please refer to manual override drawings)!
3. Auto sleep mode switches back to learning mode by pressing the RESET button or by the cycling power supply.

Installation

1. Check the valve neck. The actuator should be in a 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.
2. The direction of cistern movement can be observed on position indicator 3 1).

DIP switch settings and reset button 4 DIP switches 4 4

Factory settings: Aft switches (except 5W 2 which is in ON positions are in the OFF position!
NOTE: AU combinations of DIP switches are allowed. All functions that are selected are added consecutively.
SW 1: UR – Input signal type selector
If set to OFF position, voltage input is selected.lf set to ON position, current input is selected.
SW 2:0/2 – Input signal range selector
If set to the OFF position, the input signal is in the range of 2-10 V (voltage input) or from 4-20 mA (current input). If set to the ON position, the input signal is in the range of 0-10 V (voltage input) or from 0-20 mA (current input).
SW 3: 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 the ON position, the actuator is inverse acting (stem extracts as voltage increases).
5W 4: -••/Seq – Normal or sequential mode selector
If set to the OFF position, the actuator is working in the range 0(2)-10 V or 0(4)-20 mA. If set to ON position, the actuator is working in the sequential range: 0(2) (6) V or … 10 (12) mA) or (516) i0V) Of 110021… 20 mA).
SW 5:0 … S V/5 … 10 V – Input signal range
In sequential mode If set to OFF position, the actuator is working in the sequential range 0(2)-S (6) V or 0(4)-10 (12) mA. If set to the ON position, the actuator is working in a sequential range; S(61-10 V or 10(12)-20 mA.
SW 6:LIN/LOG – Linear or equal percentage flow through valve selector
If set to the 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 periods when the heating/cooling is off. If set to the ON position (ASTK), the valve motion is switched on. The actuator opens and doses the valve every 7 days. If set to OFF position (—), the 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 the OFF position to make the reset button function active (press it for 2 sec. )
2) Reset button 4 3
The reset button on PCB has the same function as the reset switch SW 8.
Manual override 5 (for service purposes only)
Do not manually operate the drive if power is connected!

• Remove cover 5 1
• Press and hold the button (on the bottom side of the actuator) 5 2 during manual override 5 3
• Replace cover 5 4
• Install actuator on valve 5 5

Remark: A ‘click’ sound after energizing the actuator indicates that the gear wheel has jumped into its normal position. Function test The light emitting diodes (LEDs)4 1 (green-direction indicator), 4 2 (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)
• The actuator reached set-point acc. to Y signal (LED off).
