F Setup examples
This description assumes that the controller is operated under the fol-
lowing conditions.
• A K thermocouple is used as the input.
• Control output (heat), alarm 1 and alarm 2 functions are assigned to
"control output 1," "control output 2" and auxiliary output 1, respec-
tively. Of these, only control output 1 and auxiliary output 1 are used.
• The relay output unit is mounted at control output 1.
• The upper-limit alarm is set as alarm 2. The alarm is output when the
temperature exceeds 10_C with respect to the PV .
• The program is made up of one pattern comprising four steps.
• The following figures show terminal wiring and the program used in
the setting examples.
