DANFOSS AME 113 NLX SU (01) PDF DOCUMENT

The DANFOSS AME 113 NLX SU actuator is designed for DC supply according to EN 61558-1 or AC supply according to EN 61558-1/2-6. For DC supply, one side of the secondary winding must be connected to the ground. For AC supply, the secondary winding must be connected to the ground.

Follow these steps to assemble the DANFOSS AME 113 NLX SU:

1. Open the device.

2. Connect the battery.

3. The battery switch must be set to the ON position. The battery must remain in the device to ensure the function of the device.

4. Close the device.

5. Proceed with mounting and assembly as shown in the diagrams.

Follow the connection instructions below for your specific model of the DANFOSS AME 113 NLX SU:

AME 113 NL:

24 V AC / DC ~ : Black wire

Common ground: Black wire

Control signal 0-10 V: Red wire

AME 113 NLX:

24 V AC / DC ~ : Black wire

Common ground: Black wire

Control signal 0-10 V: Red wire

Feedback 0-10 V: Yellow wire

During the initialisation of the DANFOSS AME 113 NLX SU, the device performs a self-calibration process. This process takes approximately 2 to 3 minutes, plus an additional 15 minutes. The actuator will move to its end positions to set up its operational range.

To manually adjust the DANFOSS AME 113 NLX SU, follow these steps:

1. Turn the corresponding switch to the ON position (as indicated by “1” in the diagram).

2. Press and hold the reset button for more than 5 seconds.

3. Wait until the LED starts to flash, then release the button.

4. When the actuator is in the desired position, turn the switch to the OFF position.

The actuator will now maintain this position until it receives an input signal that causes it to move.

The function display on the DANFOSS AME 113 NLX SU has the following indicators:

A – Error

B – Operation

C – Control signal

The LED status indicators on the DANFOTS AME 113 NLX SU provide information about its operational state. Refer to the table below for details:

Overrule indication: When the red LED is lit, the actuator can still be driven up and down for 20 minutes. If the button is not pressed during this time, the device will return to automatic operation.

The back channel feedback signal from the DANFOSS AME 113 NLX SU provides the following voltage-based information:

The technical specifications for the DANFOSS AME 113 NLX SU are as follows:

For the DANFOSS AME 113 NLX SU, the valve travel is directly proportional to the control signal input voltage. Within the active voltage control range of 1V to 9V, a 1V input corresponds to 0% valve travel (closed), and a 9V input corresponds to 100% valve travel (fully open). The travel increases linearly as the voltage increases from 1V to 9V.

The feedback signal of the DANFOSS AME 113 NLX SU indicates the actuator’s position. The output voltage is proportional to the actuator’s travel percentage. When the actuator travel is 0%, the feedback signal is 1V. When the travel is 100%, the feedback signal is 9V. The signal increases linearly between these two points. A signal below 0.5V indicates a “contact error”, while a signal above 9.5V indicates an “actuator error”.

To disassemble the DANFOSS AME 113 NLX SU, press the release button located on the side of the unit. While pressing the button, you can detach the actuator from its mounting.

The antitheft device on the DANFOSS AME 113 NLX SU is a protection feature that prevents unauthorized removal. To engage it, a specific component must be installed which blocks the disassembly release button, securing the actuator in place.
