7. Running
When mounting and wiring to the control panel (DIN rail) are finished, start the operation following the next
procedure.
(1) Turn the power supply to the CS4R series ON.
For approx. 3s after power on, character of the sensor type and temperature unit are indicated on the PV
display, and the input range high limit value is indicated on the SV display. See (Table 5-1).
(If any other value is set at the scaling high limit value setting, SV display indicates it.)
During this time, all outputs and LED indicators are in OFF status.
After that PV display indicates actual temperature and SV display indicates the main setting value.
(2) Input the setting value.
Input each setting value referring to “5. Setup”.
(3) Turn the load circuit power ON.
Starts control action so as to keep temperature of the controlled object at the main setting value.
