GB-7
! Flashes 6 times: saving error for adjustable pa-
rameters.
• Carry out reset.
• If it is not possible to remedy the fault, send the
actuator to the manufacturer.
! Flashes 7 times: saving error: factory default
parameters.
• Carry out reset.
• If it is not possible to remedy the fault, send the
actuator to the manufacturer.
! Flashes 8 times: saving error: user calibration.
• Carry out reset.
• If it is not possible to remedy the fault, send the
actuator to the manufacturer.
! Flashes 9 times: low voltage.
• Check actuator mains voltage supply.
• If it is not possible to remedy the fault, send the
actuator to the manufacturer.
? Blue LED lights up in accordance with op-
erating state, red LED flashes? (warning)
! Flashes once: internal temperature > 90°C.
Ambient temperature too high.
• Reduce ambient/medium temperature.
! Flashes twice: drift > 5%. Control element me-
chanically offset or moving against its mechanical
stop.
• Check control element opens and closes without
restrictions.
• Carry out reset → the actuator is recalibrated.
! Flashes 3 times: drift > 10%. Control element
mechanically offset or moving against its me-
chanical stop.
• Check control element opens and closes without
restrictions.
• Carry out reset → the actuator is recalibrated.
• Adjust the closed position.
• Carry out reset → the actuator is recalibrated.
! Flashes 4 times/5 times: control element blocked,
large mechanical offset, internal error, actuator
offset.
• Check control element opens and closes without
restrictions.
• Carry out reset → the actuator is recalibrated.
! Flashes 6 times: analogue input AI < 4 mA.
• Check analogue input signal.
! Flashes 7 times: service note: maximum number
of OPEN/CLOSE cycles exceeded.
• Carry out reset using BCSoft.
! Flashes 8 times: service note: maximum number
of changes in direction of rotation exceeded.
• Carry out reset using BCSoft.
! Flashes 9 times: service note: relay output RO1
or RO2 switched too often.
• Carry out reset using BCSoft.
? The drive shaft does not move?
! No permanent voltage supply to the unit.
• Check supply voltage.
! No signal at the unit.
• Check signal.
! Signal at incorrect input.
• Check correct assignment: DI1/DI2.
! Signal voltage incorrect.
• Check signal voltage, see page9 (Technical
data).
! Selected operating mode does not correspond
with signal specifications.
• Adjust the unit or signals.
? Blue LED does not light – but the control
element opens?
! LED defective.
• Remove the unit and return it to the manufacturer
for inspection.
? No LED lights – unit is not functioning?
! No voltage supply to the unit.
• Check supply voltage.
! Unit defective.
• Remove the unit and return it to the manufacturer.
? Red and blue LEDs flash?
! Calibration of the closed position is active.
• Wait for the calibration process to finish.
• If the calibration process is not completed suc-
cessfully, cancel it and check control element
opens and closes without restrictions
? No reaction despite input signal?
! The selected operating mode is not reading this
input– incorrectly parameterized.
• Set the parameters for the operating mode/input
in BCSoft to suit your requirements.
? No output signal?
! Minimum and maximum current values not ob-
served.
• Check/adjust the current value.
! The function is not activated in the software.
• Set the parameters in the software to suit your
requirements.
! Change-over relay terminals incorrectly assigned.
• Check electrical wiring.
? The drive shaft does not move as required?
! The selected operating mode reads the inputs
differently to expectations.
• Set the parameters for the operating mode in
BCSoft to suit your requirements.
