4 Fieldbus Power Hub Basic Diagnostics
The FieldConnex
within the Power Modules and the Motherboards. Additionally, a Basic Diagnostic Module is
available to monitor the bulk power supply status and compatibility of the mounted Power
Modules in redundant systems. The following conditions are monitored:
Availability of the bulk power supply
■
Output voltage per segment
■
Overload or short circuit per segment
■
Power Module failure
■
The status of the Power Hub is shown by LED indication and by a normally closed, voltage-free
contact. Normal operating conditions are shown by green LEDs, the voltage-free contact is
closed. See table below for detail diagnostic information.
Fault
A: Supply Under/Over Voltage Detection
> 18.5 V DC +/- 4 %
< 35.8 V DC +/- 4 %
< 17.5 V DC +/- 4 %
> 36.8 V DC +/- 4 %
B: Power Module compatibility redundant system only
All modules have
intact redundancy
partner
Only one Power
Module is fitted to a
segment
C: Power Module or load status
Power Module failure
Output overload or
trunk short circuit
