Series 9205 Operations Manual Rev A 50
NNM 4-20 mA **
R 25 volts **
** - When the specified input type is selected, a jumper located inside the case will need
to be placed on that specific input for reading this selection. If jumper is not placed on
input, then damage could occur to the board. Please consult SSI before making any
changes.
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. Clicking on this value will
display an input box from which the user can select a new value. The range is 0 to 32767.
Initial Scale
This is the initial scale 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. Clicking on this value will display an input box from which the user can select a new
value. 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. This will affect the PV value and the location of the decimal when it
is displayed. Clicking on this value will display an input box from which the user can select a new value.
The range is 0 to 4.
Open TC behavior
This is the open TC value. The options are: up scale, down scale, one trip point, and two trip points.
Input Offset
The input offset value is algebraically added to the input value to adjust the input curve on read-out. The
range is –32768 to 32767.
TRIP POINT EXPLANATION: Setting a trip point will force the value that the controller uses for calculations
to a certain value as assigned by the operator. Once the Trip Point Setpoint is reached, the controller will
begin reading the value as the Trip Point Force Value, regardless of what the actual value is inside the
furnace. The Trip Point Direction allows the operator to choose whether the controller will alter its reading
when the trip point is either above or below the setpoint.
Trip Point 1 Setpoint
This is the trip point 1 setpoint value. The range is –32768 to 32767.
Trip Point 1 Force Value
This is the trip point 1 force value. The range is –32768 to 32767.
Trip Point 1 Direction
This is the trip point 1 direction. The options are: input above setpoint or input below setpoint.
