The following is a list of the options:
B
S 12.5 volts
C T 781.25mv
E 2.5 volts 195.3125 mV
J 1.28 volts
K 78.125 mV
N 19.53125 mV
NNM 4-20 mA
R 25 volts
Filter time
The filter time is a factory applied averaging tool used to help maintain steady control in high EMI
environments. The filter time should not be adjusted without consulting SSI. The range is 0 to 32767.
Initial Scale
This is the initial scale value. Clicking on this value will display an input box from which the user can select
a new value. This could also be referred to as the starting value. For example, the initial value is the value
when 0 volts is on the selected input; or on a 4-20 mA input, it would be the value at the selected input of
4 mA. The range is –32768 to 32767.
Full scale
This is the full scale value. Clicking on this value will display an input box from which the user can select a
new value. The range is –32768 to 32767.
Decimal Point Location
This is the decimal point location value. Clicking on this value will display an input box from which the user
can select a new value. This will affect the PV value and the location of the decimal when it is displayed.
The range is 0 to 4.
Open TC behavior
This is the open TC value. The options are: up scale or down scale.
Input Offset
The input offset value is algebraically added to the input value to adjust the input curve on read-out.
Note:
The input offsets are unscaled . The range is –32767 to 32767.
Calibration
Overview
The series 9120 controller can be calibrated
using the touch screen and a calibrator.
Before performing this procedure on a newly
installed controller, the unit needs to be
powered on for at least thirty (30) minutes
for a warm up period to allow the
inputs/outputs to stabilize with the
environment.
The series 9120 has two analog inputs. Each
range has a zero and span calibration value.
A cold junction trim value must be calibrated
for thermocouple inputs.
Note: the cold
junction trim value must be performed,
if necessary, after the zero and span
