The PV display keeps
indicating the value which
was set during Scaling low
limit setting.
• Check whether the input signal source for DC voltage (0 to 5V DC,
0 to 10V DC) and DC current (0 to 20mA DC) is disconnected.
How to check whether the input signal wire is disconnected
[DC voltage (0 to 5V DC, 0 to 10V DC)]
If the input to the input terminals of the instrument is 0V DC and if
a scaling low limit value is indicated, the instrument is likely to be
operating normally, however, the signal wire may be disconnected.
[DC current (0 to 20mA DC)]
If the input to the input terminals of the instrument is 0mA DC and
if a scaling low limit value is indicated, the instrument is likely to be
operating normally, however, the signal wire may be disconnected.
• Check whether the input lead wire terminals for DC voltage (0 to 5V DC,
0 to 10V DC) or DC current (0 to 20mA DC) are securely mounted to
the instrument input terminals.
The indication of PV display is
abnormal or unstable.
• Check whether sensor input or temperature unit ( or ) is correct.
Select the sensor input and temperature unit ( or ) properly.
• Sensor correcting value is unsuitable. Set it to a suitable value.
• Check whether the specification of the sensor is correct.
• AC leaks into the sensor circuit. Use an ungrounded type sensor.
• There may be equipment that interferes with or makes noise near the
controller.
Keep equipment that interferes with or makes noise away from the
controller.
The PV display is indicating
[ ].
• Internal memory is defective.

10.2 Key operation
Problem
Presumed cause and solution
• Unable to set the SV, P, I, D,
proportional cycle or alarm
value
• The values do not change by
, keys.
• Set value lock (Lock 1 or Lock 2) is selected.
Release the lock selection.
• During auto-tuning or auto-reset.
In the case of auto-tuning, cancel auto-tuning.
It takes approximately 4 minutes until auto-reset is finished.
The setting indication does not
change in the input range
even if the , keys are
pressed, and new values are
unable to be set.
• SV high or low limit value in Auxiliary function setting mode 1 may be set
at the point where the value does not change.
Set it to a suitable value while in Auxiliary function setting mode 1.
10.3 Control
Problem
Presumed cause and solution
Temperature does not rise.
• Sensor is out of order. Replace the sensor.
• Check whether the Sensor or control output terminals are securely
mounted to the instrument input terminals.
Ensure that the sensor or control output terminals are mounted to the
instrument input terminals securely.
• Check whether the wiring of sensor or control output terminals is
correct.
The control output remains in
an ON status.
• OUT1 or OUT2 low limit value is set to 100% or higher in Auxiliary
function setting mode 2.
Set it to a suitable value.
The control output remains in
an OFF status.
• OUT1 or OUT2 high limit value is set to 0% or less in Auxiliary function
setting mode 2.
Set it to a suitable value.
• If you have any inquiries, please consult our agency or the vender where you purchased the unit.
