Switches have an altogether differ-
ent group of settings as shown in
the adjacent picture. The actuation
and deactuation point errors are
calculated against the correspond-
ing nominal values.
Error Calculation Directions de-
fine error directions to be observed
when calculating errors.
Scan Range values define the
range where MC5P searches for
the approximate actuation and
deactuation point at the beginning
of an automatic calibration of a
switch. The range limits should be
symmetrical in relation to the actuation/deactuation points.
Calibration Settings Page
The Setpoint Delay setting is of
use only when the Calibration
Method is set to Automatic. It
defines how long MC5P waits be-
fore saving the input and output
values after input value was
changed to the next calibration
point.
Maximum Allowed Calibration
Point Deviation is a limit that de-
fines how far the input signal value
of the saved point can be from the
theoretical calibration point. This
setting is used both in manual and
automatic calibration.
Again, the settings for a switch is somewhat different:
An additional Number of Repeats field is visible but no Calibra-
tion Points or Maximum Allowed Calibration Point Deviation
fields.
