Thrust actuator ARI-PREMIO-Plus
4.5.3.3 Analog feedback signal
For execution control in the Control / PLC following items have to be considered:
- If the actuator is not initialized, 0V or 0mA is published.
- When ANTI-Block ON, the actuator automatically tries to remove a blockage.
For this, the plug is lifted up to 4 times with increasing travel. The lifting of the valve plug
can also be seen on the feedback signal.
- In the end position for the tight sealing function (inhibition of force) a "capture range" is
defined. If the analog input signal get into this range, the acutator drives up to the limit
switch. Here the difference between input and output signal can be larger than in the
normal control range. The deviation is from the actuator and valve travel dependent.
- By ED management, the duty cycle of the motor is reduced to prevent an overheating.
This allows the differences between the control signal and feedback will be greater.
