Integral Preset
This is the integral preset value. This field provides an offset for the starting point for PID control, also
referred to as “Load Line” or “Manual Reset”. The range is –100 to 100.
High Limit
This is the high limit value. The range is –100 to 100.
Low Limit
This is the low limit value. The range is –100 to 100.
Aux Analog Input Setup
The Auxiliary Analog Input Setup menu option allows the
user an input selection of three inputs per board, three input
corrections per board, and three input open T/Cs per board.
There are eight (8) boards available. It is configurable for
voltage of T/C (universal input), and it is typically used for
Load T/Cs, motor speed feedback, current speed devices,
and Auxiliary Flow Meters.
Before connecting your input source to the terminals, please
verify that the input type is set up correctly. If the Input Type
is not correct, do not connect the input source to the
terminals, as damage can occur. Please consult SSi by
calling (513) 772-0060 before making any changes.

Input 1 Correction – Input 3 Correction
This option will set a correction curve for the input. The options for the input corrections are: not used,
Curve 1 – Curve 3.
Input 1 Open T/C – Input 3 Open T/C
This option will allow the user to set the direction of the open T/C for each input. The options are: Up Scale
or Down Scale.
Calibration (Auxiliary Analog Inputs)
The user will need a calibrator capable of outputting a temperature, voltage, and millivolt signal to calibrate
the zero, span or cold junction value. The user will need to connect the calibrator to one of the inputs on
the data logger for the channel that will be calibrated. It is recommended to let everything (calibrator and
data logger) sit for approximately thirty minutes to allow the temperature to achieve equilibrium. Set up
the calibrator for the specific thermocouple type, i.e. type K, type J, etc. Then, source a specific
temperature, like 1000°F, or millivolt to the connected input. It is recommended that the actual
temperature used be similar to an appropriate process temperature. For example, if your equipment
normally operates at 1700°F, then perform the cold junction calibration using a 1700 °F signal. It is
important to note that when performing a zero or span calibration,
do not use
regular thermocouple wiring.
