Installation notes
∂ The actuator may not be lagged
For electrical installation, refer to «Connection diagrams».
Maintenance notes
The low friction and robust, maintenance-free design makes regular servicing
unnecessary and ensure 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.
Should the valve electronics prove faulty, the ASE12 electronics module must be
replaced (refer to Mounting Instructions 74 319 0404 0).
Always disconnect power before fitting or removing the electronics module.
After replacing the electronics module, calibration must be triggered in order to
optimally match the electronics to the valve (refer to «Calibration»).
