contactor does not match the commanded state.
Verify wiring of filter capacitor contactor.
Stand Alone Unit (DPI MASTER) Faults
Port 1 Adapter
71
The communication card has detected a fault on the network.
(4)
Check DPI device event queue and
corresponding fault information for the
device.
Port 2 Adapter
72
The communication card has detected a fault on the network.
Port 3 Adapter
73
The communication card has detected a fault on the network.
Port 4 Adapter
74
The communication card has detected a fault on the network.
Port 5 Adapter
75
The communication card has detected a fault on the network.
Port 6 Adapter
76
The communication card has detected a fault on the network.
Port 1 DPI Loss
81
The DPI communication to a peripheral was lost.
1. If adapter was not intentionally
disconnected, check wiring to the port.
Replace wiring, port expander,
adapters, Main Control Board, or
complete Converter as required.
2. Check HIM connection.
3. If an adapter was intentionally
disconnected and the [Logic Mask] bit
for that adapter is set to “1,” this fault
will occur. To disable this fault, set the
[Logic Mask] bit for the adapter to “0.”
Port 2 DPI Loss
82
The DPI communication to a peripheral was lost.
Port 3 DPI Loss
83
The DPI communication to a peripheral was lost.
Port 4 DPI Loss
84
The DPI communication to a peripheral was lost.
Port 5 DPI Loss
85
The DPI communication to a peripheral was lost.
Port 6 DPI Loss
86
The DPI communication to a peripheral was lost.
