The Danfoss AME 140X is an actuator designed for modulating control. This guide covers essential installation, configuration, and maintenance procedures. Safety Warning: Necessary assembly, start-up, and maintenance must be performed by qualified personnel only. Always switch off the power supply before removing the cover. The device requires a 24V AC power supply connected via a safety isolating transformer.
Mounting and Installation
The actuator should be mounted with the valve stem in either a horizontal position or pointing upwards.
- Valve Check: Inspect the valve neck before installation.
- Positioning: Ensure the actuator is in the 'steam up' position (factory setting) before mounting.
- Securing: Mount the actuator securely on the valve body using the ribbed nut. Tighten by hand; no tools are required.
- Wiring: Connect the actuator according to the provided wiring diagram.
DIP Switch Settings
The actuator features 7 DIP switches for configuration. Factory settings have all switches in the OFF position, except SW 1 which is ON.
- SW 1 (Input signal range): OFF for 2-10V/4-20mA; ON for 0-10V/0-20mA.
- SW 2 (Direct/Inverse): OFF for direct acting; ON for inverse acting.
- SW 3 (Normal/Sequential): OFF for normal; ON for sequential mode.
- SW 4 (Sequential range): OFF for 0-5V/0-10mA; ON for 5-10V/10-20mA.
- SW 5 (Flow characteristic): ON for linear to modified flow (VZL valves); OFF for standard.
- SW 6 (Anti-blocking): ON to enable valve motion every 7 days; OFF to disable.
- SW 7 (Input type): OFF for voltage input; ON for current input.
Manual Override
Warning: Do not manually operate the drive if power is connected. Do not dismount the actuator from the valve if it is in a stem-down position, as this risks the actuator getting stuck.
- Remove the cover.
- Press and hold the button on the bottom side of the actuator during manual override.
- Replace the cover after adjustment.
- Install the actuator back on the valve.
A 'click' sound after energizing indicates the gear wheel has returned to the normal position.
LED Signalization
The LED provides status feedback:
- Green (Constantly lit): Positioning mode (retracting or extracting stem).
- Green (Flashing 1s): Self-stroking mode.
- Yellow (Constantly lit): Stationary mode (reached end position).
- Yellow (Flashing 2.5s): Stationary mode.
- Red (Flashing 1s): Error mode.
- Dark: No power supply.

Practical help
Common problems
Actuator gets stuck
Ensure the actuator was not dismounted while in a stem-down position.
Error Mode (Red LED flashing)
Check wiring and power supply; perform a reset by pressing the reset button for 2 seconds.
No LED indication
Verify that the power supply is connected and active (24V AC).
Before use
- Verify power supply is 24V AC via safety isolating transformer.
- Check valve neck for compatibility.
- Ensure actuator is in 'steam up' position (factory setting).
- Verify wiring against the diagram.
- Ensure the ribbed nut is tightened by hand.
