Remark
System Fault Blocking EnXX Automatic stoker fault
The control device has a fault message log in which a maximum
of five fault messages can be saved. The fault messages are
displayed with the date, time and fault type (fault number); the
query is carried out in the sequence of the entered fault
messages in the "Fault Message" menu.
The last (most recent) fault message is in first position (No. 01);
the previous fault messages are shifted down by a position upon
each new fault message. The fifth fault message is deleted when
a new fault message appears.
If a heat generator defect occurs (fault message 30-1 or 31-3) and
system frost protection is active at the same time, boiler start-up
protection is switched off and thus the heating circuit pumps are
started to minimise the danger of system freezing.
Five fault messages from automatic stokers (condensing
versions) with OpenTherm
These fault messages come from automatic stokers and are
categorised as either locks, blockages or warnings.
The display and further processing of logical fault messages from
the SMILE system can be enabled or suppressed via a
corresponding configuration (see "System Parameters" menu,
parameter 13 (logical fault message)).
The display and further processing of fault messages from a
connected automatic stoker can be controlled as follows.
Using parameter 27 in the "System Parameters" menu, you can
specify which of the fault messages transmitted by an automatic
stoker is forwarded to the SMILE system.
Using parameter 28 in the "System Parameters" menu, you can
specify whether or not fault messages of an automatic stoker are
to be written to a separate fault memory. If the parameter is set to
ON, another menu appears in the menu with the designation
"Fault 2". Only faults of the automatic stokers are saved in this
fault memory.
