Ex
ceeding rated voltage
Measures must be undertaken outside field devices (refrigerant valve CDV..MVL661..)
to prevent temporary faults from ex
ceeding more than 40 % of rated voltage (transient
protection).
Maintenance notes
The refrigerant valve is maintenance-free.
Valve repair
The valve can not be repaired. It has to be replaced as a complete unit.
