Service
CAUTION:
Do not disassemble the valve and actuator combination. This assembly is
factory-calibrated, and should only be replaced by qualified personnel.
Always disconnect power before fitting or removing the electronics
module.
• The low-friction and robust, maintenance-free design makes regular servicing
unnecessary and ensures a long service life.
• The valve stem is sealed from external influences by a maintenance-free gland.
• If the red LED is lit, the electronics must be recalibrated or replaced.
• If the valve electronics are faulty, they must be replaced. After replacing the
electronics, they must be recalibrated. See Calibration.
• If required, the circuit board can be replaced. Order Part Number ASE12.
