4.2.5 How to set the SV limiter setting
The SV limiter is for setting a settable range with upper and lower limits.
The range is a basis for setting the proportional band for the PID control.
Constant value run mode screen

S04-3 SV limiter upper limit setting screen
* The SV limiter upper limit is set in this screen.
* Use the ▲/▼ key for the setting.
* The set value is a value of MAX (upper limit) for which the SV setting is allowed.
* The value is set at “1200” at factory shipment.
* A small value of SLH contributes to prevent erroneous setting operation, resulting in
prevention of fire or failure.
S04-4 SV limiter lower limit setting screen
* The SV limiter lower limit is set in this screen.
* Use the ▲/▼ key for the setting.
* The set value is a value of MIN (lower limit) for which the SV setting is allowed.
* The value is set at “0” at factory shipment.
* Holding the MODE key pressed for 2 seconds moves each setting screen to the operating mode screen.
* In about 2 minutes, each setting screen (or any setting screen) automatically moves back to the operating
mode screen.
