-
INACTIVE
The binary switching input B3 has no function.
ACTIVE HI
The internal flow counter is reset to 0.0 if there is an H level at input B3 for at least 100 ms.
ACTIVE LO
The internal flow counter is reset to 0.0 if there is an L level at input B3 for at least 100 ms.
STARTH STOPL
The counter is started by creating an H level at input B3 and stopped by creating an L level
at input B3.
STARTL STOPH
The counter is started by creating an L level at input B3 and stopped by creating an H level
at input B3.

During calibration, the value of the current loop does not follow the current process.
If an ampere meter detects in the 4...20 mA loop a deviation from the desired value of
"4.000mA", the measured value must be entered. The correction value is accepted
following the query to save and confirm with yes.
