switching the display. This function is useful when performing incremental changes to the
SP
value.
As shown in the following table, up to four (4)
SP values can be switched according to the
ON/OFF status of the external switch inputs when the ‘3: Switching of SP No.’ is selected at the
external switch input function assignments ‘
C-10 ’ and ‘ C-11 ’ in the function setup. If the number
of SP values is two (2), set either one of ‘ C-10 ’ or ‘ C-11 ’ to ‘3: Switching of SP No’. However, in
this situation, the
SP
number cannot be updated using the [
∧ ∧ ∧ ∧
] key or [
∨ ∨ ∨ ∨
] key. Only the
SP
value
can be updated.
EXTERNAL SWITCH INPUT STATUS
INPUT 1 (DI1) INPUT 2 (DI2)
SP NUMBER BEING SELECTED
OFF OFF SP-0
ON OFF SP-1
OFF ON SP-2
ON ON SP-3
Notes:
1. If the [ DISP ] key is pressed during the setup operation while the setpoint is blinking, the
SP number and SP value cannot be stored and are returned to the previous value.
2. When ‘1: Analog Setup’ is selected at the function setup ‘ C-03 ’ and the SP value is
established via the analog setting voltage, the SP number and SP value cannot be
changed using the [ ∧
∧ ∧
∧ ] key or [ ∨
∨ ∨
∨ ] key.
3. If no key is pressed within ten (10) seconds while the multi-setting flow rate is displayed,
indication is automatically returned to the instantaneous flow rate display.
PROCEDURE FOR CHANGING FLOW RATE IN ANALOG SETTING
To change the
SP
value using an external setpoint voltage, confirm ‘1: Analog Setup’ is selected at
the function setup ‘ C-03 ’ (the analog setup function is disabled as the default setting). For
instructions to change the function setup modes, refer to ‘SECTION 6 – APPLICATION
OPERATION’.
The setpoint voltage range is selected at the function setup ‘ C-05 ’. The analog setpoint voltage value
to the SP value can be calculated from the calculation formulas in the following table:
‘C-05’
VOLTAGE
RANGE
HOW TO CALCULATE SETPOINT VOLTAGE
0 0 to 5 Vdc
Setting Voltage [V]= Setting Flow Rate
÷
Full-Scale Flow Rate X 5.00
1 1 to 5 Vdc
Setting Voltage [V]= Setting Flow Rate
÷
Full-Scale Flow Rate X 4.00+ 1.00
Notes:
1.
When ‘1: Function enabled’ is selected at the function setup ‘ C-28 ’, the full-scale flow rate
can be set. Both the full-scale flow rate output voltage ( PV output voltage) and the setpoint
input voltage are changed. The scaling flow rate is set in the parameter setup mode. For
instructions to change the function setup and parameter setup modes, refer to ‘SECTION 6 –
APPLICATION OPERATION’.
2. Do not supply a negative setpoint voltage or a setpoint voltage greater than 5 Vdc to the
MFC. Doing so may cause MFC malfunction or faulty operation.
