5.3 Basic Operation after Power-ON
After the unit is mounted to the control panel and wiring is completed, operate the unit following the
procedures below.
(1) Turn the unit power supply ON
※
After confirming the rated voltage, polarity and wiring, turn the power ON via contacts
such as switch or relay. If any mistakes are made, an electric shock, malfunction or errors
may be caused.
After the power is turned ON, the PV Display indicates the input type, and the SV Display indicates
the Input range high limit value (for thermocouple, RTD inputs) or Scaling high limit value (for DC
voltage, current inputs) for approximately 3 seconds. (Table 5.3-1)
During this time, all outputs and the indicators are in OFF status.
Control will then start, indicating the PV in the PV Display and SV in the SV Display.
While the control output OFF function is working, the PV Display indicates [
.].
Indication differs depending on the selection in [Indication when control output OFF].
