(3) Numerical display 2
Note 1: Graph scale interval, maximum value, minimum value of bar graph display can be
changed.
Note 2: Operating range display can be changed.
Note 3: When the power supply is turned off, the pressure values will not be displayed.
Display settings
The graph scale interval, minimum/maximum value of display setting and bar graph ranges can
be changed via the DN codes shown below.
1. Use UP and DOWN to select "C.dnSt", and then ENTER to confirm.
2. After d-
○○○
appears, the set value appears. After "d-
○○○
" appears, the shown DN code number is indicated. The set value
is shown in "
●
".
3. Use UP and DOWN to change the DN code number. When a desired DN code number (d-0CF) is selected, the value for
each horsepower as listed in the table also appears. Check that the pump horsepower indicated on the installed pump
name plate is the same as the pump horsepower value displayed.
4. If they are different, change the displayed value, as follows:
• Touch ENTER to confirm. The value flashes so that you can change it.
• When the value is still flashing, use UP and DOWN to change the displayed value to the correct value for the pump
horsepower, and then touch ENTER to confirm.
5. Finally, use BACK to return to the default value such as "Cool".
