Anti-block retraction
program
Anti-Block On:
If the valve stem or plug is blocked (i.e. if the thrust is reached
before the final position), an intelligent retraction algorithm attempts
to remove the blockage. The plug is raised a maximum of four times
(the lift is increased with each new attempt) until the blockage is no
longer present.
If the blockage cannot be removed, the orange LED is set.
Anti-Block Off:
The retraction algorithm is deactivated.
The orange LED is set if a blockage occurs.
Economy - wear
reduction program
The wear on the valve and actuator mechanism can be reduced to a
minimum by implementing various protective measures to extend
the lifetime.
Economy On:
This operating mode affords maximum protection for the valve and
actuator mechanism as follows:
- Adaptive hysteresis band (refer to 5.6.1)
- Temperature management on (see 5.6.2)
Economy Off:
The actuator must respond as quickly as possible:
- Fixed hysteresias band
- Temperatur management off
- Yin control signal starts immediately when the power is returned
