Watchdog
You can check how many times the unit has been switched on and look at
the date and time of the last ten starts. This can be useful if there have been
power failures or if for any reason the Zenith restarts due to a fault
condition. The Zenith can be backed up from a battery which automatically
cuts in during power failure, battery backed up units will continue
uninterrupted operation and therefore will not register a loss of mains
power. If, however the battery was to fail during a mains power interruption,
a start-up would be recorded once power has been restored.
The following parameters can be accessed by directly entering the
parameter number. To do this, enter the
program mode
and then
type
in
the appropriate
parameter number
.
Important Notice
When a relay has been failed, due to a fail signal having been received on its
associated digital input, the relay LED will flash on and off, between yellow
and red, to indicate that the relay has been failed but not put out of service.
After the maximum attempts P300 have been made to start the device relay
and it is put out of service then the relay LED will remain lit on red until
such time that the input is reset.
