11 Alarms and messages of WRG 3010 E
11.1 Message system
Messages such as " Pump collective fault " are detected by the heat recovery controller via digital inputs or are
generated by the controller itself, e.g. " Valve fault ". These messages are then sent to the system centre via the
CAN bus and archived there with date, time and message priority. All messages thus receive an "incoming" and
an "outgoing" time stamp.

Note about the message priorities
Only the last digit of the priority, in the example above x 2 , is decisive for the message / alarm allocation. The
first digit is only used for the allocation to a maintenance group, in this case 2 x to WRG 3010 E. Thus,
messages with PRIO "20" and alarms with PRIO "21" and PRIO "22" are available. The alarms with the
priorities "21" and "22" act directly on the alarm relays "PRIO1" and "PRIO2" of the system centre. For more
information about the priority concept, see "
System Centre Operating Manual ".
Some messages must be acknowledged by the user, which is only possible with the LDSWin PC
software.

Practical tip
Since many messages and alarms are based on digital and analogue input signals, the wiring should
always be checked in the event of a fault and for remedial action! In addition, the visualisation page
"
Troubleshooting " is available to quickly detect and eliminate possible causes for missing switch-on or
running conditions.
