Brochure

If the valve electronics prove faulty, the electronics module must be replaced by the
ASE1 (DN15…32) or ASE2 (DN40…65) replacement electronics module.
Repair
Mounting instructions no. 35678 are included.
Caution
Al
ways 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", page 5).
Caution
Under
operating conditions within the limits defined by the application data, the
actuator will become hot, but this does not represent a burn risk. Always
maintain the minimum clearance specified, refer to "Dimensions", page 12.
Disposal
Do not dispose of the actuator in domestic waste. This applies in particular to the PCB.
The law may demand special handling of certain components, or it may make
environmental sense.
Observer all current local laws.
Warranty
Observe all application-specific technical data.
If specified limits are not observed, Siemens Switzerland Ltd / HVAC Products
does not assume any responsibility.
