1 INTRODUCTION
1.1 PRECAUTIONS BEFORE STARTING
: Installation and electrical connection should be carried out in accordance with local regulations and only by qualified
technicians!
1.2 TROUBLESHOOTING
Diagnostic for the LED
- At start-up, the LED remains red for 1 second, and then switches to solid Green.
Blinking Green
- Calibration mode.
Permanente Red
- Error, the magnet is not within the proximity of the sensor or is out of the range.
Green
- Status OK.
Instability of the signal 4-20 mA
- Check if the pipe is connected to the ground; connect the 0 V of the 24 V to the same ground.
- Make sure the e-Lift is not located in an area near high voltage or a variable-frequency drive.

3.4 INSTALLATION INSTRUCTIONS
1. All installation, adjustment and maintenance should be carried out by a competent electrician.
2. Do not exceed the maximum ratings given in the specifications and printed on the label.
3. The electrical connections should be made as described in the user’s manual.
4. Before any maintenance operation the main power should be turned off.
5. Don’t forget to put the spring into the tube after fitting the magnet holder.
6. Make sure the e-Lift rod is located at the bottom of the valve stem.
: Do not attempt to open the product as this will invalidate the warranty!

4 CALIBRATION
4.1 CALIBRATION WITH WATER & WITHOUT CALIBRATION TOOL
Initial situation: The magnet of e-Lift should be within measuring range sensor; The LED should be green before starting
calibration.
1. Activate calibration mode
- Press button marked LA for at least 4 secs. or until the LED starts blinking green.
2. Set 0% closed position
- Close the valve to reach lowest position.
- Press button marked LA for at least 2 secs. or until the LED appears red.
3. Set 100% open position
- Open the valve to reach the highest position.
- Press button marked LB for at least 2 secs. or until a solid red LED appears.
If the time taken to fully open the valve from the closed position exceeds 40 seconds, the calibration process times out
and you will need to repeat the process. Please proceed step 1 first then step 3.
4. End calibration mode
- Press buttons LA and LB simultaneously (< 1s) to finish calibration and read current value.
Note:
Any of the individual steps for settings can be selected independently. The calibration process can be ended at any time
(step 4).
This mode shows how the valve was calibrated without tools.

The e-Lift can be calibrated using the calibration tool and push buttons in the junction box (or optionally with the D22
Electronic Valve Controller interface). Alternatively, please isolate the main valve cover chamber before proceeding with
calibration using the tools.
1. Close the main valve
2. Unscrew the X101 stem position indicator (if supplied)
3. In place of the X101, insert the calibration tool with the wing screw unscrewed on the Delrin (white plastic) stem
4. Once the calibration tool is placed on the Delrin stem & e-Lift surface position, screw the wing screw onto the Derlin
stem
5. Activate calibration mode
- Press the LA button for at least 4 secs. until the LED starts blinking green.
6. Set 0% Close Position
- Press the LA button for at least 2 secs. until the LED appears solid red.
7. After setting the new closed position, lift the calibration tool and place the wedge corresponding to the valve size
between the surface of the e-Lift and the nut of the calibration tool (see drawing above).
8. Set 100% Open position
- Press the LB button for at least 2 secs. until the LED appears solid red.
9. End calibration mode
- Press buttons: LA and LB simultaneously (< 1sec.) to finish calibration and read current values.
10. Remove wedge then unscrew the calibration tool from the Delrin stem
11. Once the calibration tool is removed, replace the X101 (if supplied)
12. Open the isolation cocks to restore valve operate
The calibration is completed!

5 OPTION MENU
5.1 FACTORY RESET
The e-Lift can be reset to restore all setting to the factory settings.
Please note if using factory reset, all values and positions displayed will be lost.
1. Activate reset
- Press buttons LA and LB simultaneously for at least 4 secs. until the LED starts blinking green.
2. Reset
- Pressure buttons LA and LB simultaneously for at least 4 secs. until the LED appears red to complete the reset.
3. After reset
- All values are reset.
- Current position of the magnet is displayed.
- Reset is deactivated (permanent green LED).
Note:
Resetting can be aborted without any changes before step 2.
To abort reset, activate LA & LB simultaneously (< 1sec).

5.2 INVERTING THE 4-20 MA SIGNAL
The signal 4-20 mA of the e-Lift can be inversed (valve close = 20 mA & valve fully open = 4 mA).
This option can be useful in some cases for SCADA systems.
1. Activate invert
- Press button LB button at least 4 secs. until the LED starts blinking green.
2. Invert signal
- Press buttons LA and LB simultaneously for at least 4 secs until the solid red LED appears to complete the invert
signal.
3. After inverting
- The output signal is inverted.
- Current position of magnet is displayed.
- Inverting is deactivated (permanent green LED).
Note:
Inverting can be aborted without any changes before step 2.
To abort inverting, activate LA & LB simultaneously (< 1 s).
