The following table presents an example of assignment of the physical inputs of the 362MC which would
correspond to the functions of a 362-D.
5.6.1 Explanatory note on calibration
Via the
Calibrate resistance input
function, the 362MC supports the adjustment of its 4
th
analogue input
to the actual values of a connected resistor feedback sensor which is necessary during commissioning,
for example, in order to compensate fitting tolerances.
The following procedure is recommendable here:
1. Start the calibration process
Set parameter
R scale
to value
kalibr
; the factory setting for a resistor feedback sensor of
0 to 200R is employed for the display.
2. Calibration zero point
Move actuator to CLOSED position
(e.g. in Manual mode) until the
actuator is completely closed!
Set parameter
R scale
to value
Rmin
; the current value of the resistor feedback sensor will be
stored as 0%=zero point.
3. Calibration end position
Move actuator to OPEN position
(e.g. in Manual mode) until the
actuator is completely OPEN!
Set parameter
R scale
to value
Rmax
; the current value of the resistor feedback sensor will be
stored as 100%=end position.
Each entered value will be stored only when the following procedure is observed: select
R scale
,
select parameter entry with
Prgm
button and press
Prgm
to save the value.
5.6.2 Explanatory note on scaling
The parameters
Scale-F
= scale factor and
Scale-0
= scale zero point are employed to scale physical
variables, such as those setpoints and parameter entries, within the 362MC´s internal value range from
0 to 1. When internal values with physical scaling are required for display purposes, the values
concerned are scaled back with the same parameters.
