6.4 VIEWING THE EVENT LOG
The model 5220 remote start module maintains
a log of the last 15 shutdown alarms and mains
fail/returns to enable the operator or engineer to
view the past alarms history. Only shutdown
and electrical trip alarms are logged; warning
alarms are not logged. Once the log is full (15
shutdown alarms), any subsequent shutdown
alarms will overwrite the oldest entry in the log.
Hence the log will always contain the 15 most
recent shutdown alarms.
The alarm is logged, along with the date and
time of the event in the format shown in this
example.
To view the event log, press the log button
. The LCD display will flash the log symbol
to confirm that
the event log has been entered.
In this example, the oil can symbol represents
an oil pressure shutdown, backed up by the
flashing shutdown symbol in the LCD display.
The value displayed means that the oil pressure
shutdown occurred on November 1
st
2002 at
8:17.
Press down
to view the next most recent shutdown alarm:
In this example, the hand/button symbol
represents an emergency stop shutdown,
backed up by the flashing shutdown symbol in
the LCD display.
The value displayed means that the emergency
stop button was pressed on November 1
st
2002
at 11:50.
Mains Failure is logged using a flashing
symbol.
Mains Return is logged by illuminating the mains available LED.
Continuing to press down
will cycle through the past alarms until all 15 logged alarms have been viewed,
after which the most recent alarm will again be showed and the cycle will begin again.
To exit the event log and return to viewing the instruments, press the log
button.
