5.6 Auto/Manual control function
Name,
Functions
Auto/Manual control function
• If Auto/Manual control function is selected in the OUT/OFF key function selection, Automatic or
Manual control function can be switched by pressing the key in the PV/SV display mode.
If control action is switched from automatic to manual or vice versa, balanceless-bumpless
function works to prevent sudden change of manipulated variable.
When automatic control is switched to manual control, the 1st dot from the right on the SV display
blinks, and the output manipulated variable (MV) can be increased or decreased by pressing
or key to perform the control.
By pressing the key again, the mode reverts to the PV/SV display mode (automatic control).
(Whenever the power to the controller is turned on, automatic control starts.)

5.7 Control output OFF function
Character
Name,
Functions
Control output OFF function
• A function to pause the control action or turn the control output of the unused
instrument of the plural units OFF even if the power to the instrument is supplied.
[
] is indicated on the PV display while the function is working.
• Once the control output OFF function is enabled, the function cannot be released
even if the power to the instrument is turned OFF and ON again.
To cancel the function, press the key again for approx. 1 second.
5.8 Output manipulated variable (MV) indication
Name and functions
Output manipulated variable indication
•
In the PV/SV display mode, press the
key for approx. 3 seconds.
Keep pressing the key until the output manipulated variable shows up, though the main
setting mode appears temporarily during the process.
(The SV display indicates output manipulated variable and the decimal point blinks at a cycle of
every 0.5 second). If the key is pressed again, the mode reverts to the PV/SV display.
6. Running
After the controller has been mounted to the control panel and wiring is completed, it can be started
in the following manner.
(1) Turn the power supply to the TP40A ON.
Turn the power supply to the TP40A ON.
• For approx. 3s after the power is switched ON, the sensor input character and the temperature unit
are indicated on the PV display and input range high limit value is indicated on the SV display. See
(Table 5-1). (If any other value has been set in the scaling high limit setting, the set value is indicated on
the SV display) During this time, all outputs and LED indicators are in OFF status.
• After that, control starts indicating input value on the PV display, and main setting value on the SV display.
• While the Control output OFF function is working,
is indicated on the PV display.
(2) Input each setting value.
Input each setting value, referring to “5. Setup”.
(3) Turn the load circuit power ON.
Starts the control action so as to keep the controlled object at the main setting value.
