If the end positions cannot be reached due to inaccurate analogue setpoint signals
(0/4 mA or 20 mA), a tolerance for the setpoint within the end position range can be
set. If the tolerance is exceeded or not reached, the actuator continues the operation
until the full end position has been reached. This ensures that the actuator opens
and closes fully.
Customer settings M0041
Positioner M0145
Tolerance CLOSE M0150
Tolerance OPEN M0151
Default values:
Tolerance CLOSE = 0.0 %
Tolerance OPEN = 100.0 %
Setting ranges: (in percent of the travel)
Tolerance CLOSE = 0.0 – 5.0 %
Tolerance OPEN = 95 – 100.0 %
Setting range can be limited in directions OPEN and/or CLOSE.
This prevents end position(s) OPEN and/or CLOSED from being approached in
modulating duty. The actuator stops when reaching the set limit value.
For OPEN-CLOSE control (LOCAL or REMOTE OPEN-CLOSE operation mode),
this limitation is not active. The valve can then be run into the end positions either
via the local controls or from remote.
