DANFOSS AME 113 NLX SD (01) PDF DOCUMENT

To avoid injury and damage to the DANFOSS AME 113 NLX SD, it is absolutely necessary to read and observe the instructions carefully.

The device is supplied with 24V (safe voltage). To avoid electric shocks, all connections should be made according to existing regulations.

The device must be connected to a DC supply according to EN 61558-1 or EN 61558-2-6 or EN 61558-2-16. For AC supply, a transformer according to EN 61558-1 or EN 61558-2-6 must be used.

Only operate the DANFOSS AME 113 NLX SD on a connected valve.

Before installing the actuator, make sure the nut on the valve is tight.

Follow these steps for assembly:

1. Place the actuator on the valve.

2. Tighten the nut to secure the actuator to the valve body.

3. Connect the wiring according to the wiring diagram.

4. Place the cover back on the actuator.

Please note that the battery will discharge during long-term storage of the DANFOSS AME 113 NLX SD.

The battery for the DANFOSS AME 113 NLX SD should be charged in advance. The approximate battery charging time is 20 hours.

Connect the device according to the wiring diagram. The wire colors for the DANFOSS AME 113 NLX SD are as follows:

AME 113 NLX Main Connection:

Black: 24V AC/DC ~

Black/White: 24V AC/DC ⏚ / Common ground

Red: 0-10V Control signal

NLX Feedback Connection:

Yellow: 0-10V Feedback signal

Yellow/White: ⏚ / Common ground

Initialisation for the DANFOSS AME 113 NLX SD starts automatically after it is connected to the power supply. The process takes between 2-3 to 15 minutes.

During initialisation, the actuator moves to one end position and then to the other. After this cycle, the actuator is ready for operation.

Note: For initialisation to complete successfully, the battery must be charged. If it fails to initialise after more than one attempt, replace the device.

The manual overriding button is located under the cover of the DANFOSS AME 113 NLX SD.

1. Push and hold the manual overriding button.

2. To move the actuator spindle up, turn the screwdriver counterclockwise until the stop is reached.

3. To move the actuator spindle down, turn the screwdriver clockwise.

The function display consists of the following components:

A – Button

B – LEDs

C – LED 1 / LED 2 indicators for status

*Initialization: Visual alternative information on display is shown (duration approx. 20 min., several movements).

*On initialisation: Alternating display (Green – Orange) for 20 minutes. If the problem persists, replace the device.

**For initialisation, the battery must be charged and connect more than once, replace the device.

The following settings are available for the back channel:

The selectable speed settings are 3 s/mm, 8 s/mm, and 12 s/mm.

The following settings are available for the test mode:

The active voltage control range for the DANFOSS AME 113 NLX SD is from 1 V to 9 V. Signals below 1 V or above 9 V will drive the valve to its fully closed or fully open positions, respectively.

For the DANFOSS AME 113 NLX SD, the feedback signal is proportional to the valve stroke. As the valve stroke increases (moves from 0% to 100%), the feedback signal (Y control) increases linearly from 0 V to 10 V.

Disassembly of the DANFOSS AME 113 NLX SD is performed in the reverse order of assembly. First, remove the cover, then disconnect the wiring, and finally, loosen the nut to remove the actuator from the valve.

To use the antitheft feature, insert and tighten the provided screw on the side of the DANFOSS AME 113 NLX SD. This will secure the actuator and help prevent unauthorized removal.
