Function Details
Output operation
W
The output operation can be selected from the following:
Output (hysteresis mode and window comparator mode) corre-
sponding to instantaneous flow or output (accumulated output and
pulse output) corresponding to accumulated flow
(Default setting: Hysteresis mode, Normal output)
Simple setting mode
W
Only the set values for instantaneous flow and accumulated flow can
be changed. The output mode, output type, display color, and
accumulated pulse output cannot be changed.
Display color
W
The display color can be selected for each
output status. The selection of the display
color provides visual identification of ab-
normal values.
Delay time setting
W
The time from when the instantaneous flow
reaches the set value to when the switch
output operates can be set. Setting the
delay time can prevent the switch output
from chattering.
(Default setting: 0 s)
Digital filter setting
W
The time for the digital filter can be set to
the sensor input. Setting the digital filter
can reduce chattering of the switch output
and flickering of the analog output and the
display.
The response time indicates when the set
value is 90% in relation to the step input.
(Default setting: 0 s)
FUNC output switching function
W
Analog output, external input, or copy function can be selected.
(Default setting: Analog output)
Selectable analog output function
W
1 to 5 V or 0 to 10 V can be selected for the analog voltage output
type. (Default setting: 1 to 5 V)
External input function
W
The accumulated flow, peak value, and bottom value can be reset
remotely.
Accumulated value external reset: The accumulated flow value is reset via external in-
put signal.
In accumulated increment mode, the accumulated
value will reset to and increase from zero.
In accumulated decrement mode, the accumulated
value will reset to and decrease from the set value.
* When the accumulated value is stored to memory, every time the accumulated
value external reset is activated, the memory will be accessed. Take into
consideration that the max. number of times the memory can be accessed is 1.5
million times. The total number of external inputs and the accumulated value
memorizing time interval should not exceed 1.5 million times.
Peak/Bottom value reset: The peak value and bottom value are reset.
W
The output is forced ON/OFF when starting the system or during
maintenance. This enables confirmation of the wiring and prevents
system errors due to unexpected output.
For the analog output type: When ON, the output will be 5 V (or 10 V
when 0 to 10 V is selected) or 20 mA, and when OFF, 1 V (or 0 V when
0 to 10 V is selected) or 4 mA.
* Also, the increase or decrease of the flow will not change the ON/OFF
W
The accumulated value is not cleared even when the power supply is
turned OFF. The accumulated value is memorized every 2 or 5
minutes during measurement and continues from the last memorized
Green for ON, Red for OFF
value when the power supply is turned ON again.
Red for ON, Green for OFF
The max. writable limit of the memory device is 1.5 million times,
Red all the time which should be taken into consideration.
Green all the time
W
The max. (min.) flow rate is detected and updated from when the
0.00 s
power supply is turned ON. In peak (bottom) value display mode, this
0.05 to 0.1 s (Increments of 0.01 s)
max. (min.) flow rate is displayed.
0.1 to 1.0 s (Increments of 0.1 s)
W
1 to 10 s (Increments of 1 s)
The user can select whether a security code must be entered to re-
20 s
lease the key lock. At the time of shipment from the factory, it is set
30 s
such that a security code is not required.

values

The product can be returned to its factory default settings.
0.1 to 1.0 s (Increments of 0.1 s)

W
20 s
When the flow is close to 0 L/min, the product will round the value
30 s
down and zero will be displayed. A flow value may be displayed even
when the flow rate is 0 L/min due to high pressure or depending on
the installation. The zero cut-off function will force the display to
zero. The range to display zero can be changed.
For the setting of functions and operation methods,
refer to the "Operation Manual" on the SMC website.
