Toshiba LF620 Instruction Manual page 115

Note 1:Since the flow volume direction code is B (Bidirectional forward/reverse automatic selection),
•When you select forward/reverse multi-range,
forward direction totalized value (count value) is displayed for operation in the
forward direction range, and reverse direction totalized value (count value) is
displayed for operation in reverse direction range.
Note 2: If you reset the totalizer, flow counts for both directions will be cleared to zero at the same time.
Note 3:Non-volatile memory is used to store the totalizer count. Therefore, the value will be retained in
the memory even if power is turned off.
Note 4:In the case of sealed specification, start and stop switches can only be used.
(Clear operation cannot be used.)
●Operation using the digital input
Remote operations for the totalizer and pulse output can be performed using the digital input.
Set the digital input function for this purpose referring to 8.2.19 "Digital Input."
