CKD FLUEREX PF Series - Operations: Display and output indicators; Unit lamps and displays; Switch output parameters; Hysteresis and clearing integrating flow

PF-F/PFU Series
Operations
· Three types of setting are available according to the application.
●
Switch output parameters
●
0 < L < H
●
0 < (L-h) ≤ L < (H-h)
Note)
1) Switch output ON indicates that the transistor is energized.
2) For safety, set the output only when the upper level equipment is in
stop state.
3) The settings of parameters 0 and 1 should satisfy the following
conditions. Otherwise operation cannot be guaranteed.
Note that the output is always OFF if L=H=h=0 (factory default).
1) In the write mode described on the right, clear
with key operation.
2) Clear by turning the power OFF.
●
To clear the integrating ow
· Set when the ow rate pulsates, causing the
switch output to chatter.
●
Hysteresis
Note: Between PF500F to PF4000F/PFU500F to PFU2000F and PF8000F/PF16000F, the unit is different. In the explanation above, the explanation
is made for the model No. of PF500F to PF4000F as a representative. For PF8000F/PF16000F, change the reading way of the unit.
PF500F to PF4000F/PFU500F to PFU2000F: L/min (normal)
PF8000F/PF16000F: m

/min (normal) (the value becomes 1000 times of (L/min normal) and a decimal point is added.)
[Measurement mode]
· Switches H and L of the
integrating ow display.
[In write mode]
· Increases the blinking digits.
●
Up key
[L]
· Displays the lower digits of
integrating ow. (Unit: L liter)
[H]
· Displays the higher digits of
integrating ow. (Unit: L liter)
●
Unit lamp Integrating ow
[Measurement mode]
· Switches the display to the write
mode when held down for 2 seconds.
[In write mode]
· Moves the blinking digit to the right.
●
Shift key
[Measurement mode]
· Switches the display between the
instantaneous ow rate and integrating ow.
[In write mode]
· Use to conrm the setting.
●
Change key
· Displays the instantaneous ow rate/
integrating ow.
[In write mode]
· Displays the output setting value, etc.
●
5-digit digital display
· When the lamp is ON, the 5-digit
digital display displays the
instantaneous ow rate.
●
Unit lamp Instantaneous ow rate
Indicates the switch output status.
