INTERFACE
PROBLEMSWARNING: Electrical shock hazard Diagnosing electrical and processor problems require access to the electrical enclosure while power is on. Only qualified electrical technicians, who are trained in how to avoid voltage hazards, should perform troubleshooting procedures that require access to the B32 Input/Output enclosure while power is on.
Fault | Possible cause Solution |
Terminal does not power up.
Improper connection to power source
Incorrect input voltage level.
DC power wires reversed (DC terminals only).
Power terminal block not fully seated (PV300 terminals only).
rVerify wiring and connec- tions to power source.
rVerify correct voltage is present at power terminals.
rMake sure DC power posi- tive and negative are con- nected to the proper termi- nals.
rVerify power terminal block is snapped onto base of PV300 Micro.
