6. OPERATION FLOW
Setting Example
● Set a Set value (SV) to 200 C
● Set Autotuning (AT)
● Change the type of Alarm 1 from “Deviation high” to “Deviation high/low”
7. ERROR DISPLAYS
Input error displays
Display Description Solution
Measured value (PV)
[Flashing]
Measured value (PV) exceeds
the input range.
Prior to replacing the sensor, always turn
the power OFF or change to STOP with
RUN/STOP transfer.
Check input range, sensor and sensor
connection.

Over-scale
Measured value (PV) is above
the display range limit high.

■ Set value change and registration
The highlighted digit indicates which digit can be set. Press shift key to go to a
different digit. Every time the shift key is pressed, the highlighted digit moves.
However, the changed data is not stored by the operation of the Up and Down keys
alone. In order to store the new parameter value, the SET key must be pressed within
1 minute after the new value is displayed. The new value will then be saved and the
display will move to the next parameter.
If no key operation is performed within 1 minute without pressing the SET key, this
instrument returns to the PV/SV monitor screen and the set value will not be changed.

Parameters in the Initial setting mode should be
set according to the application before setting any
parameters related to operation. Once the
Parameters in the Initial setting mode are set
correctly, no further changes need to be made to
parameters for the same application under normal
conditions. If they are changed unnecessarily, it
may result in malfunction or failure of the
instrument. RKC will not bear any responsibility
for malfunction or failure as a result of improper
changes in the Initial setting mode.
