11. Troubleshooting
11.1. Faults
When a pack level fault occurs, all stacks are disconnected. The following sections describe the
different faults and the conditions that trigger them. In general, all warnings have a similar trigger
condition as their corresponding fault. The following discussion will focus on the term fault and all
descriptions can be applied to the compatible warning.
11.1.1. Ethernet Connection
This fault is related to communication faults between the Battery Control Panel and any of the stack-
level BMS that is configured as installed
pack_stack[n].installed
.
gbc_fault_eth_conn
▪
The Battery Control Panel could not communicate with one or more installed stacks
This fault is usually triggered due to:
▪
Battery Control Panel network configuration issues. Refer to
▪
IP networking configuration is different between the Battery Control Panel and the stack-level
BMS. Verify that
gbc_int_ethernet
register settings are compatible with the stack-level IP register
settings.
▪
The expected stack-level BMS is not on the network or receiving power
To find the stack-level BMS that has a connection fault, refer to the register
gbc_eth_bridge_status[*].is_connected
. The pattern of data should match the
pack_stack[*].installed
.
11.1.2. Controller Heartbeat
gbc_fault_controller_wdt
▪
Fault indicating that an external controller did not provide a heart beat update within the
configured period. Refer to
on details of this configuration.
11.1.3. Ready Stacks
This fault represents a configurable minimum limit to how many stacks must be
the pack remain connected and manage the battery power. Refer to
for details of this
operation and configuration.
pack_fault_ready_stacks
▪
Fault indicating that the minimum number of
stacks for the pack has been exceeded
Refer the
Stack Status
) on the Operator Interface to observe which stacks have
been either disabled or have faulted.
