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 UltraTWIN restarts due to a fault
condition. The UltraTWIN 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 P*300 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.
