ERROR #5 – Low battery
ERROR #6 – Encoder blocked
ERROR #7 – Current too high
ERROR #8 – Limit sensor error
ERROR #1 - Calibration error 1
ERROR #2 - Calibration error 2
ERROR #3 - Calibration error 3
ERROR #4 - Actuator feedback
communication error.
ERROR #5 - Battery low
ERROR #6
ERROR #7 - Actuator blocked
feedback - Master controller disabled
- Poor signal or no signal to master
controller
- Defective RF module in the
actuator
Battery low
Encoder failure
- Unevenness, e.g. on the screw,
thread, causing high movement
resistance
- High transmission or motor
resistance
- Faulty current
system
Faulty limit switch system
EU-GX actuator alarm
Bolt retraction to mounting position
took too long.
Bolt maximally extended as it did not
meet any
extension.
Bolt extension too short. The bolt
met resistance too early during the
calibration process.
For the last x minutes, the actuator
did not receive a data package via
wireless communication.
After this error is triggered, the
actuator will set itself to 50%
opening.
The error will reset after a data
package is received.
The actuator will detect battery
replacement after voltage
rises and launch calibration
-
- Check if the master controller is
operating
- Reduce the distance from the master
controller
- Call service.
Replace the batteries
- Re-calibrate by holding down the
registration button until the LED flashes
3 times.
- Call service.
measurement
Locked/damaged actuator piston. Check
the
actuator.
• actuator was not screwed properly
onto the valve
• the actuator was not fully tightened
onto the valve
• actuator movement was excessive, or
resistance during non-standard valve
encountered
• motor load measurement failure
occurred
Check the assembly and recalibrate the
actuator.
• valve movement was too small, or a
non-standard valve
encountered
• motor load measurement failure
• motor load measurement inaccurate
due to low battery charge
Check the assembly and recalibrate the
actuator.
• master controller disabled
• poor signal or no signal originating from
the master controller
• defective RC module in the actuator
• battery depleted
-
• while changing the opening of the
valve, excessive load was encountered
Recalibrate the actuator.
