Meter with 3-wire output
In this configuration, it is preferred to activate input TAMPER of channel A (register 320 bit 3 = 1) and
deactivate channel B (register 320 bit
4=0) which is not no used.
Meter with 5-wire output
In this configuration, the 2 inputs (A & B) must be activated (register 320 bits 0 and 4 = 1). The
combination of the pulse counts on inputs A & B (IMPULSION_1 & IMPULSION_2) allows to know the
quantities measured in the 2 directions.
The activation of signals FRAUDE_1 & FRAUDE_2 (register 320 respectively bit 3 and 7 = 1) allows to
generate alarms of fraud and wrong flow direction.
