HBM CANHEAD - PIN assignment for the male and female CAN connectors on the back of the housing

Connection
44 A01185_11_X00_00 HBM: public CANHEAD
Meaning of the LEDs:
The LEDs indicate the measuring point status whenever there is a ”change of
status”. When an SG is connected to measuring point 1, the green LED flashes
(Status 1) once (corresponding to the measuring point) and then stays on.
1. Green LED: OK, measuring point recognized
2. Red LED:
If there is an error when powering up the system with SGs con
nected, the red LED flashes the number of times to correspond
to the corres‐ ponding error number (Error code, see Table
below) and then stays on (flashes up to error number 32 at
maximum, i.e. 32 times).
The red LED also flashes in measurement mode when there is
a change in status (SG overloaded or SG connected/discon
nected), to correspond to the corresponding measuring point;
should, for example, an SG become disconnected from mea
suring point 8, the red LED will flash 8 times.
