Using as a crrent loop supply
Refer to the following wiring example.
5. Setup
After power is turned ON, the input characters and temperature unit will be indicated on the PV display, and the
input range high limit (for thermocouple, RTD input) or scaling high limit (for direct current, DC voltage input)
will be indicated on the SV display for approx. 3 sec. (Table 5-1).
During this time, all outputs and LED indicators are in an OFF status. Operation will then start, indicating the
PV (process variable) on the PV display, and A1, A2, A3 value on the SV display.
