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

PV value (present value)

SV value (target value)

Hold MODE key pressed for 2 seconds.

Input 1 setting screen

Each set screen

Each setting mode

Press the ▲ key three times.

Press it, however, twice for TTM-204.

Control setting mode

Press MODE key three times.

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.

Hold MODE key pressed for 2 seconds.

For program run mode screen:

PV value (present value)

SV value (PRoG)

Hold MODE key pressed for 2 seconds

Setting mode is the same as that for constant

value run mode.
