INPUT PROGRAMMING
Determine the direction of the TCB (Thermocouple Break) and set switch 1
on SW1 to OFF for upscale action or ON for downscale action (See Figure 1).
Switches 2 through 5 on SW1 al-
low selection for thermocouple type.
Only one of these switches should
be on. Turning on more than one
of these switches may cause the
SC1290 to operate in an unpredict-
able manner.
For a type J thermocouple, turn on
switch 2.
For a type K or type T thermo-
couple, turn on switch 3.
For a type E thermocouple, turn on
switch 4.
For a type R or type S thermocouple, turn on switch 5.
Use the chart (Figure 2, below) to select the input type and range for your
process. Turn on the appropriate switch(s) (as indicated) on SW1 for the input
range desired.
