SP lamp:
Lit when the flow rate
setpoint is displayed.
PV lamp:
Lit when the instantaneous flow
rate is displayed.
OK lamp
:
Lit when the deviation between the flow set value
and instantaneous flow rate is in the allowable range.
Set the allowable range in the parameter setup.
(For details on how to set parameters, )
ALM lamp :
Lit when an alarm occurs.
EV1 lamp
:
Lit when event 1 output is ON.
EV2 lamp :
Lit when event 2 output is ON.
7-segment display:
Displays the instantaneous flow rate,
flow set value, totalized flow, amperage
to the valve and the operating mode.
It also displays parameter setup values, function
setup values and details of alarms.
RUN key:
Use this key to change the operating mode.
key:
Use this key to decrement the setting value.
Also use it to move to the function setup mode.
key:
Use this key to increment the setting value.
Additionally, this key is used to change to
the device information display mode.
key:
Use this key to move to a desired digit
when changing setting value. Also use it to
move to the parameter setup mode.
L lamp
*
1
:
Lit when the totalized flow is
displayed.
Blinks when the cumulative
flow event occurs.
L/min lamp * 2 :
Lit when the instantaneous flow rate
or flow set value is displayed.
DISP key:
Use this key to switch the details displayed
on the 7-segment display.
ENT key:
Use this key to fix and store the set value
to memory.
Also use it to reset the cumulative flow and to
reset alarm and move to the function setup mode.

instead of L on some models.
*2. This lamp is used for mL/min instead of L/min on some models.
Note
•
Technical terms used in this manual are defined as follows:
•
SP (setpoint): The flow set value (or flow rate setpoint)
•
PV (process variable): Instantaneous flow rate (or controlled flow rate)
•
Operating mode: 3 modes (valve fully closed/valve control/ valve fully
open)
