MAIN IN %
Displayed the magnitude of input signal that the positioner recognizes
as percentage.
If the size of the input signal recognized by the positioner differs
from output signal of the DCS or calibrator, check the voltage of
the power supply.
If the supply current is normal, please reset <
IN ZERO

> values in <
TUNING

MAIN IN mA
Displayed the magnitude of input signal that the positioner recognizes
as mA
.
If the size of the input signal recognized by the positioner differs
from output signal of the DCS or calibrator, check the voltage of
the power supply.
If the supply current is normal, please reset <
IN ZERO
> and
<
IN END
> values in <
TUNNING
> of main parameter.
MAIN VEL
Displayed currently operating speed of the valve as numbers.
As the value, between -2047 to +2048, negative numbers
indicate speed at close, and positive numbers indicate speed at
open.
0 means stop and
the larger the absolute value, the faster the
speed.
MAIN DEV %
Displayed the percentage of error between the current input signal
and valve opening value.
The larger the error, the lower the control characteristic.
