It is the responsibility of the customer to ensure that the predicted and actual flange loads are within the specified limits over all possible application pressures and temperatures.
It is the responsibility of the customer to ensure that the predicted and actual flange loads are within the specified limits.
For flange loads to be acceptable, the force and the moment when plotted must lie beneath the limiting force-moment line.
CAN Wiring / Shield Terminations & Limitations
The exposed length of CAN wiring must be limited to less than 3.8 cm / 1.5 inches from the end of the shield to the terminal block.
Low Limit Value using the DVPII Service Tool.

порог ошибки позиционирования вала, вызывающий аварийное отключение привода
http://www.rtd-universal.com/files/374596720-40185_J.pdf
Position Error
(Shutdown
Position)
During run time, the valve
will check if the position
feedback and the
demanded position are
the same. If not, a
position error will be
flagged, and the valve will
be shut down.

Product Manual 26740:
Position Sensor (LVDT) Difference Settings:
“Alarm difference” is the threshold level that a cylinder position sensor error alarm will be annunciated.
“Shutdown difference” is the threshold level at which a shutdown will be initiated.

Сервоклапан не может обеспечить позиционирование вала привода из-за ошибок. Это приводит к выключению привода. А эта ошибка говорит о том, что исчерпан лимит выключений, вызванных указанной причиной.
