Set value lock Unlock
• Locks the set values to prevent setting errors.
The setting item to be locked depends on the selection.
• Auto-tuning (AT) cannot be carried out if Lock 1 or Lock 2 is selected.
• (Unlock): All set values can be changed.
(Lock 1): None of the set values can be changed.
(Lock 2): Only main setting mode can be changed.
(Lock 3): All set values – except input type and Controller/Converter – can be
changed. However, changed values revert to their previous values
after power is turned off because they are not saved in the
non-volatile memory.
Do not change any setting item in Auxiliary function setting mode 2.
If any item in Auxiliary function setting mode 2 is changed, it will
affect other setting items such as the SV and Alarm value.
Be sure to select Lock 3 when changing the set value frequently via
software communication. (If a value set by the software
communication is the same as the value before the setting, the
value will not be written in non-volatile memory.)

Sensor correction function
This corrects the input value from the sensor. When a sensor cannot be set at the exact location where
control is desired, the sensor measured temperature may deviate from the temperature in the controlled
location.
When using multiple controllers, sometimes the measured temperatures (input value) do not match (even
if SV is the same value) due to differences in sensor accuracy or dispersion of load capacities.
In such a case, the control can be set at the desired temperature by adjusting the input value of sensors.
However, it is effective within the input rated range regardless of the sensor correction value.
PV after sensor correction = Current PV + (Sensor correction value)
Loop break alarm
The alarm will be activated if the PV (process variable) does not reach the Loop break alarm span
setting within the time allotted to assess the Loop break alarm after the MV (manipulated variable) has
reached 100% or the control output high limit value. The alarm will also be activated if the PV (process
variable) does not drop to the Loop break alarm span setting within the time allotted to assess the Loop
break alarm after the MV has reached 0% or the control output low limit value.
When the control action is Direct (Cooling), read “drop to” for “reach” and vice versa.
Energized/De-energized
[If alarm action Energized is selected]
When the alarm output indicator is lit, the alarm output (between terminals 8 and 9) is conducted (ON).
When the alarm output indicator is unlit, the alarm output is not conducted (OFF).
[If alarm action De-energized is selected]
When the alarm output indicator is lit, the alarm output (between terminals 8 and 9) is not conducted (OFF).
When the alarm output indicator is unlit, the alarm output is conducted (ON).
