Range Functions

Normal/reverse
external switching
range Switches between the normal and reverse ranges by inputting a switching
command contact from the gear section.
It is also possible to output the normal/reverse range distinctive contact output
(status signal) using the same timing.
Analog output
1
When AUTO is selected for an analog output
Normal direction: 4 - 20 mA DC
Reverse direction: 4 - 20 mA DC
2
When WIDE is selected for an analog output
4 - 20 mA DC is output according to either range No.1 or range No.2,
whichever has the wider span.
With pulse output
There is no distinction in output between the normal and reverse direc-
tions. The pulse scale is also the same.
The built-in counter simply integrates the flow rate without distinguish-
ing between the normal and reverse directions. However, when normal/
reverse differential flow integration is selected, the integration of the "-"
direction (subtraction) is available.
Example: In the normal direction
-100
→
-
99
→
-
98 ··· 0
→
1, 2, 3
In the reverse direction
100
→
99
→
98 ··· 0
→
1, 2, 3
With indication
With a reverse flow rate, the "–" symbol will appear on the flow rate dis-
play.
When there is a pulse output, it is possible to select the normal/reverse
differential flow integration function.
Contact input
Range switching command contact input
Normal direction: when opened
Reverse direction: when closed
Contact output (select the function required.)
Normal/reverse distinction status signal
The contact output status at shipment is as follows.
Range No.1: Open
Range No.2: Closed
Reverse setting is also possible.
