4-1 Switching Displays
CAUTION
Do not operate the console keys using a sharp object such as a mechanical pen-
cil or screwdriver. Doing so might damage the console.
 Basic operation
Basic operation is used to change the display to instantaneous flow
rate (PV), flow set value (SP), totalized flow value, or valve amperage.
Normally, when the power is turned ON, the instantaneous flow rate
is displayed in basic operation mode. When this is the case, operat-
ing the [DISP] key changes the contents of the 7-segment display as
described below.
Power ON
Instantaneous ow rate display (PV and L/min lamps lit)
Flow set value display (SP and L/min lamps lit)
Totalized ow display (L lamp lit)
Valve amperage display (SP, PV, L, and L/min lamps go out)

Handling Precautions
•
If there is no operator input for approximately 10 seconds while
the flow set value is being displayed, the display automatically
reverts to the instantaneous flow rate display.
•
The "L" lamp is labeled "mL" on the MQV9020/9050 or "m
3
" on
the MQV0200. The "L/min" lamp is labeled "mL/min" on the
MQV9020/9050.
z Indicating instantaneous flow rate (PV display)
When the power is turned ON, the PV and L/min lamps light, and the
instantaneous flow rate is indicated on the display.
Handling Precautions
•
When the operating mode is set to fully closed, and the flow
rate is zero, and when the operating mode is switched to the
control mode or fully open mode, the operating mode (
OFF
/
ON
/
FULL
) is displayed for about one second.
•
When an alarm occurs, the alarm code and the PV are dis-
played alternately.
