Description
Sets and/or displays the mA value of the
Feedback signal that represents the 0%
output shaft position.
Sets and/or displays the mA value of
the Feedback signal that represents the
100% output shaft position.
Sets and/or displays the curve used to
calculate the Feedback signal.
Trims the Feedback signal at 4 mA.
The Feeback sourcing circuit is factory
calibrated and normally does not require
recalibration.
Trims the Feedback signal at 20 mA.
The Feeback sourcing circuit is factory
calibrated and normally does not require
recalibration.
Sets and/or displays the function of a
DCM-3 connector pin. The DCM-3 pin
that is used to source the Feedback
signal can instead be used to power
an output shaft position-sensing
potentiometer on models of Beck
actuator that do not use the CPS-5.
If the pin use parameter is not set to
Feedback, the Feedback circuit is
disabled. If the pin use parameter is
set to Pot, 5 V dc is output from this pin
to power the potentiometer. Setting
the parameter to None disables the
Feedback and the potentiometer supply.
Argument n and Information
n = the desired Feedback signal
in mA at 0% output shaft position .
The minimum value is 3.00 and the
maximum value is at least 4.00 less
than the Feedback signal value for the
100% output shaft position.
n = the desired Feeback signal in mA
at 100% output shaft position. The
minimum value must be at least 4.00
greater than the Feedback signal value
for the 0% output shaft position. The
maximum value is 21.00.
n = "0": Linear (curve disabled)
n = “1”: Inverse Demand (curve
enabled)
n = the present Feedback signal from
the DCM-3 as measured in mA.
n = the present Feedback signal from
the DCM-3 as measured in mA.
n = “0”: None
n = “1”: Feedback enabled
n = “2”: Potentiometer power enabled
