Saving Relay Setup
When changes have been made to any parameter in the configuration menu, the save command
must be used to permanently store the new settings.
If changes have not been saved, they will
be lost when the product is powered
down. Press ENTER to select the Save
command.
Press ENTER again, and you will be
prompted with SURE?. If you are sure
you wish to save the changes, press
ENTER again, otherwise, press ESC to
cancel the save operation.
Event Log Menu
Every time a relay trips, event details can be recorded in the event log with a time and date
stamp. This is useful for analysing the system problems, and because events are recorded to a
time resolution of 100ms, the sequence of trip events can be studied. The date and time are
maintained by an internal real time clock with battery backup. The product stores details of the
last fifty trip events, and if more trips occur, the oldest records are deleted so that new
information can be recorded.
IMPORTANT: Event information will be
lost if the product is powered down. The
event log will also be cleared if the relay
configuration has been altered in the
configuration menu.
The most recent trip is held in the highest
event record. In this example, Relay 1
tripped on March 14, 2004 at 10:22 am,
because of an under voltage condition.
You can view the trip settings using the
UP/DOWN keys, but no changes can be
made. To view the other event
information, press ENTER to edit the
event number, then use the UP/DOWN
keys to step through them.
If no trip events have taken place since
the last power-down, you will find blank
records.
