At power-up, the module runs through an initial self-diagnostic check. If the module does
not have valid calibration data the scale data LED will flash green at a rate of about once
a second.
The door will open to the right revealing two groups of connectors and one red button for
C2 calibration at the “cal low weight” parameter value. The number of pins in the
connector will depend on the number of channel options obtained. The left group of
connectors will be for weigh scale inputs and the group of connectors on the right will be
for relay I/O.
