11.15.6 How the DMC50 control unit displays and processes an alarm
The alarm
is an irregular event that always causes the dryer to stop to ensure the safety of operators and the machine.
In the presence of an alarm the status bar shows a description of the event and turns flashing red. In this condition it is
not possible to reset the alarm as the cause is still present.
When an alarm is no longer active but has not been reset, the status bar shows a description of the event and is
permanently lit (red). In this condition the alarm can be reset as the cause has been removed.
With dryer operating (ON)
: the presence of one or more alarms is flagged
on the display with the status bar changing from green to red.
With the dryer stopped (STANDBY)
: the presence of one or more alarms is
not flagged at all on the display, with the exception of alarm no. 6 (ICE) which
is the only alarm which is displayed and automatically resets with the dryer
stopped (STANDBY).
It is only when the operator wants to start the dryer with the
button that
the DMC50 control unit prevents the dryer starting up in the presence of an
alarm and displays the alarm status by changing the colour of the status bar
(red).
