8. Operation
8.1 Starting Operation
After the unit is mounted to the control panel and wiring is completed, operate the unit following the
procedure below.
(1) Turn the power supply to the ACS-13A ON.
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. See (Table 8.1-1).
During this time, all outputs and the indicators are in OFF status.
Control will then start, indicating the PV (process variable) on the PV display and SV (desired value) on
the SV display.
While control output OFF function is working, PV display indicates
. (Indication of the PV display
depends on the selection in [Indication when output OFF].)

(2) Input each set value.
Input each set value. Refer to “7. Settings”.
(3) Turn the load circuit power ON.
Control action starts so as to keep the control target at the SV.
Main setting mode (When setting the SV to 100 ):
1
Proceed to Main setting mode.
Press the
key in PV/SV display mode.
The unit proceeds to Main setting mode.
2
Set SV.
Set SV with the
or
key.
3
Register the SV.
Register the SV by pressing the
key.
The unit reverts to PV/SV display mode.
4
Control starts.
Control starts so as to keep the measuring temperature at 100 .
