After flash upgrades for new firmware, the relay may require that the R_S command be issued
to reset its memory of the settings. In this case, the R_S command is available from Access

The relay will pulse the ALARM output when entering Access Level 2 and the calibration access
level. When the R_S command is issued, the relay is disabled and the ALARM output contact
closes until the process is complete, unless an alarm condition already exists.
SER (Sequential Events Records)
Access Level 1
The SER command displays the last 512 sequential event records. To limit the number of
records displayed, use date parameters with the SER command. SER d1 shows only events
triggered on or after the date specified by d1. SER d1 d2 shows only events triggered on or
between the specified dates. The following is an example of the SER report. See Section 10:
Event Reports and SER for a complete description of the report.
