HIS Command (Event Summaries/History)
HIS x displays event summaries or allows you to clear event summaries (and corresponding
event reports) from nonvolatile memory.
If no parameters are specified with the HIS command:
= HIS <ENTER>
the control displays the most recent event summaries in reverse chronological order.
If x is a number (1 - 16):
= HIS 6 <ENTER>
the control displays the x most recent event summaries. The maximum number of available
event summaries is a function of the LER (length of event report) setting. The control saves up
to sixteen 15-cycle event reports if setting LER = 15 and eight 30-cycle event reports if setting
LER = 30.
If x is “C” or “c”, the recloser control clears the event summaries and all corresponding event
reports from nonvolatile memory.
The event summaries include the date and time the event was triggered, the type of event, the
fault location, the maximum phase current in the event, the power system frequency, the number
of the active setting group, the reclose shot count, and the front-panel targets.
To display the recloser control event summaries, enter the following command:
=>HIS <ENTER>

The fault locator function influences information in the EVENT and LOCAT columns. If the
fault locator is enabled (Access Level 2 SET command enable setting EFLOC = Y), the fault
locator will attempt to run if the event report is generated by a trip (assertion of TRIP Relay
Word bit) or other programmable event report trigger condition (Access Level 2 SET L
SEL
OGIC
®
Control Equation setting ER). The fault locator should not be enabled unless three
phase voltage is connected to the control.
