OUT1 and OUT2 outputs
OUT1 can be configured as the impulse output or Flow Switch contact. OUT2 can be set as the impulse
output, flow switch or status contact.
1) OUT1 setting
Impulse output
In impulse output parameter setting, it is possible to change the logics (polarity) of the electrical
signal (on-state/off-state), furthermore, to set the impulse output to which direction the volumetric counter
will respond (volume run in positive direction, in opposite direction and in both directions) as well as your
own impulse constant, including its indication (imp/L or L/imp) and impulse width.
*Note
Period [ms] = pulse width [ms] + inter-pulse gap [ms] where gap ≥ width
The pulse width is selected in steps by scrolling through predefined values with or buttons.
Flow switch operation
In “flow switch” status output parameter setting, it is possible to change the logics (polarity) of the
electrical signal (on-state/off-state), furthermore, to set the output to which direction the output will respond
(flow in positive direction, in opposite direction and in both directions) as well as your own switching point
value.
*Qlimit - the number of decimal places is given by DN of the given meter and cannot be changed.
