11.15.5 How the DMC50 control unit displays and processes a service warning
The service warning
is an irregular event that must be flagged to operators/maintenance technicians. It does not
jeopardise the safety of the machine/operators and it does not stop the dryer, with the exception of the HdS parameter
(STOP dryer due to high dew point), which can be set to stop the dryer.
In the presence of a service warning, the status bar shows a description of the event and turns flashing orange. In this
condition it is not possible to reset the service warning as the cause is still present.
When a service warning is no longer active but has not been reset, the status bar shows a description of the event and
is permanently lit (orange). In this condition the service warning can be reset as the cause has been removed.
With dryer operating (ON)
: the presence of one or more service warnings is
flagged on the display with the status bar changing from green to orange.
With the dryer stopped (STANDBY)
: the presence of one or more service
warnings is not flagged at all on the display.
It is only when the operator wants to start the dryer with the
button that
the DMC50 control unit still enables the dryer to be started in the presence of
a service warning, and displays the warning status by changing the colour of
the status bar (orange).
Resetting a service warning
:
1-
Touch the screen on the status bar where the service warning is shown.
2-
Confirm the service warning is to be reset with OK, or exit without resetting
with Cancel.
NOTE
! After resetting service warnings, the operator/maintenance technician must verify/solve the problem that
caused the service warning.
Service warnings never reset automatically, with the exception of service warning no. 19 (malfunction of electronic
condensation drainer), which is factory-set to enable automatic resetting (Ard parameter
→
Yes setting).
