the same time, but actually, the blocks “NO FUEL”, “EMERGENCY STOP” and “MANUAL
STOP IN AUTO” are an exception since they can be activated even in presence of other blocks
When a fault occurs, whatever be its category, the audible alarm is activated (“ALARM
OUTPUT”, terminal 16) as well as the corresponding visual signal. Such signal can be an
indicator on the front panel (fault area) or a m
essage “FXX” on the display
“MULTIFUNCTION”. In the case of an indicator it flashes.
The audible alarm stays active for the time programmed through the parameter P54 than it
turns off automatically (if P54 is equal to 999 the siren does never turn off automatically, if P54
is equal to 0 the siren never turns on), while the visual signal keeps on flashing until the
operator doesn’t ”recognize” it.
The “recognition” involves the pressing of “MODE / ACK”. As a consequence, the signal stops
flashing and stays turned on and the audible alarm (if still active) is disabled.
Once the operator has recognized the alarms, they are automatically cancelled by DST4600A
when the corresponding cause ceases to exist. If the alarm is cancelled, the visual signal turns
off, too.
While the blocks and deactivation can be cancelled only by switching the key selector to
“OFF/RESET”.
