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 1V DC and if
a value corresponding to 1V DC 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 1mA DC and
if a value corresponding to 1mA DC 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.

9.2 Key operation
Problem
Presumed cause and solution
• Unable to set the SV, A1 value,
etc.
• The values do not change by
,
keys.
• Set value lock (Lock 1 or Lock 2) is selected.
Release the lock.
The setting indication does not
change within the input range
even if the
,
keys are
pressed, and new values are
unable to be set value.
• Scaling high or low limit value in the Setup mode may be set at
the point where the value does not change.
Set it to a suitable value while in Setup mode.
9.3 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.
• If you have any inquiries, please consult our agency or the shop where you purchased the unit.
