8 Service reminder
8 .1 Service Reminder
The Service Reminder functionality is available on all, except the
900PB00 PCB configuration.
This functionality requires the large EEPROM therefore it will not be
available on the 900PB00 PCB configuration.
8 .1 .1 Service Reminder
The Service Reminder will remind the owner/user of the appliance to
service the appliance at a specified
Service_Interval
(factory setting).
When service is not done within the specified time, a service reminder will
be shown on the screen, alternating with the normal status display.
The
Service_Interval
can be set as the number of burn hours or the
number of operational (appliance is powered) hours.
This can be done by setting the
Service_Hour_Counter
(factory)
parameter.
8 .1 .2
Service Overdue logging
When the service reminder has become active, the time it takes before
service is actually done is being logged by the 900PB (in hours). This
time is called the Service Overdue time. With this log the factory can read
back how long service was overdue on the system/appliance which can
be useful when handling warranty claims. A maximum of 15 Service
moments can be logged by the 900PB, when the log is full it will overwrite
the oldest log entry.
Each time the Service Reminder is being reset, a new service moment is
counted and the Service Overdue counter will be stored in the log/history.
8 .1 .3
Service Reminder implementations
There are two types of service reminders: (Normal) Service Reminder
and Service Shutdown.
Service Reminder
The (normal) Service Reminder will only show the service reminder
message on the screen and will log how many time the ser-vice is
overdue, and the appliance will remain fully operational.
Service Shutdown
The Service Shutdown has the same functionality as the Service
Reminder but will shut-down the appliance after the specified
Service_
Shutdown_Period
(factory setting) after the service reminder became
active (message is displayed).
The appliance will shut-down and no demands are handled anymore.
This way the owner/user has a warning before the appliance will actually
shutdown. Shutting down the appliance is stored in the burner (main)
control so disconnecting the display will not enable the appliance. Re-
enabling the appliance is only possible by resetting the Service Reminder
(Shutdown) which is done by the installer.
NOTE: The Service Shutdown is only available for 850 Platform products
systems and is not supported for 900 Platform products (yet).
8 .1 .4 Resetting the Service Reminder
The Service Reminder (or Shutdown) can be reset by the installer that
services the appliance.
When the Service Reminder is being reset, a service moment will be
counted and the Service Overdue counter will be stored in the log/history.
It is possible to reset the Service Reminder counters before the Service
Reminder was actually set.
This should be done when the appliance was serviced before the Service
Reminder was active. This will mean an overdue coun-ter of 0 hours will
be stored on the log (which makes sense because the service was not
overdue, but ahead of schedule).
8 .1 .5 Menu’s and Parameters
Service Reminder status information can be viewed from the Information
menu. Here the installer can also reset the service reminder (accessible
by any user-level).
(Sub) Menu item Description
Service History
View the service history (log). For each service
moment the service overdue counter is stored.
When the overdue counter is 0 hrs, this means
service was done before the service reminder
was active.
The log is ordered so the most recent service
moment is shown first (on top of the list).
Hours since last
service / Burn hours
since last service
Shows the number of hours (or burn hours)
since the last service moment. Depends on the
Service_Hour_Counter
setting (burn or
normal hours).
Hours till service /
Burn hours till service
/ Hours till shutdown
Shows the number of hours (or burn hours) until
service is required.
Depends on the
Service_Hour_Counter
setting (burn or normal hours).
When the Service Shutdown function is enabled
and the Service Reminder is active, the number
of hours until the appliance is shut-down will be
shown.
Reset Service
