Service
CAUTION:
Do not disassemble the valve and actuator combination. This assembly is
factory-calibrated, and should only be replaced by qualified personnel.
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 required, the circuit board can be replaced. Order part number ASE12.
