Event Log Memory
The log memory allows up to 80 fault, alarm, shutdown, isolation and other maintenance events to be date
and time stamped and stored in system non-volatile memory for later retrieval and analysis with 1 being the
first occurring event and 80 being the last.
Note: If the module is removed from the equipment for troubleshooting purposes, each time it is powered up
it will write to log, potential overwriting data that may be necessary for troubleshooting. Ensure that you
disable the event log via the display or the module to preserve the data
