3.3.4 Measurement channel LED indicators
The measurement channel LED indicators (Fig. 3-1,
⑧
and
⑨
) provide information on the status
of the corresponding measurement channel and the sensor excitation. There are separate LED
indicators for access via CAN bus or EtherCAT® bus. The measurement channels are arranged
as follows (left to right):
1.
Voltage
: voltage measurement status
2.
Current
: current measurement status
3.
Power
: power calculation status
After switching-on the HV Breakout Module, all measurement channel LED indicators are lit
red, indicating the start-up process of the module. Once the module has initialized itself
and no errors were detected, the LED indicators will fade out.
After self-initialization, the device checks the connected shunt module. Meanwhile the
measurement channel LED indicators of the current channels ("Current") are lit red. If the
shunt module is correctly detected, the measurement channel LED fades out again.
The measurement range has to be
identically configured
on both the ECAT and the CAN
side, otherwise the module side that was configured first will not send measurement values
but a specified error value. This is indicated on the module by
measurement channel LED
indictors permanently lit in red
.

The configurations stored in the measurement module on
the CAN or EtherCAT® side differ from each other (all three
LEDs of the corresponding side)
