6.2 When using the CF1H as a simplified program controller
(1) Turn the power supply to the CF1H on .
For approx. 2s after the power is turned ON, the type of sensor and the unit designated in Sensor input
designation (page 12, 13) are indicated on the PV display, and the rated maximum value is indicated on
the SV display.
See [table 6.1-1].
During this time, all outputs and LED indicators are in their OFF status.
After that, the display reverts to the PV/SV display.
When the Control output OFF function is working, the item selected in Display selection when control
output is off is displayed on the PV display. (See page 32.)
(2) Input each setting value and each step time referring to Chapter 4. Operations
(page 13ff), especially page 17 (Setting value memory) and page 35 (Program control
change, Step time setting). Then the PV display will indicate the actual temperature
and the status turns standby.
(3) Turn the load circuit power ON.
(4) Program control start
If Automatic start is designated in the Program start Auto/Manual designation (page 10), it will switch to
warm-up status for approx. 2 seconds after the power is turned on, and then will automatically start the
program control from step 1.
If Manual start is designated in Program start Auto/Manual designation (page 10), it will switch to
warm-up status for approx. 2 seconds after the power is turned on, and then it reverts to standby status.
In this status, if the
OUT /
OFF
key is pressed, it starts the program control from the step 1.
While the program control is being performed, the change of Step number (by Setting value memory
number) is ineffective.
To make the step time progress faster.
The step time progress becomes 60 times as fast as usual when the FAST key is pressed.
To end the program control during the process.
The program control is ended if the OUT /
OFF
key is pressed for approx. 1 second or longer.
To change the displays.
In the PV/SV display, if the MODE key is pressed for approximately 3 seconds, the Output manipulating
value display mode is activated, and if the MODE key is pressed again, the Step rest time display will be
indicated (see page 38.).
Instrument status when power failure is restored.
When power is restored after a power failure occurs during program control, the CF1H performs the
program continuously.
The PV display blinks until the step at which the power failure occurs is finished.
