The following illustration describes the operation of the module.
Behavior on Encountering an Error
During power-up, the module carries out its own self-tests (REPROM , RAM, Link display, etc.).
If an error is detected at the end of these tests, the module switches to fall back mode, the outputs are at 0.
Similarly, if, when operating normally, the module detects an internal error (in RAM or the watchdog, for example), the outputs are positioned to 0 and the display shows dashes (----) on the screen.
On power outage the machine parameters are saved (Tare mode, Zero offset, etc.) whereas the operating parameters are lost (Thresholds, number of measurements used to calculate flow rate, etc.).
