3.3. ALARMS.
RK-2006LP controller continually checks operations of installed devices as well as
alarm sensors. In case of failure, the device activates alarm and proper operations
are carried out. Information on the problem is also shown on the display. In addition
depending on nature of damage the inner sound alarm system may be activated. To
cancel alarm, first identify the cause and repair it and then STOP button shall be
pressed. If alarm is cancelled and required repairs did not follow, sound alarm
system will be turned off only. In case more than one alarm has been activated,
information on each alarm will be displayed alternately.
Out of fuel alarm.
If in IGNITION mode the controller fails to detect a flame within the time specified by
the technician, „Out of fuel alarm” will be activated. To turn on the controller again
first refill fuel, cancel the alarm with STOP button and begin setting-up process by
pressing START button.

CAUTION! This alarm does not result in engagement of inner sound system and
does not require cancelling. Once the hopper cover is closed, the programmed
process will be carried out from the moment when it was interrupted (it returns to the
mode that was before alarm activation).
Auger ignition alarm.
If the auger has been fitted with temperature sensor, and the programmed setting of
„Auger ignition temperature” was exceeded, it will result in activation of „Auger
ignition alarm”. The controller will switch off the auger, fan and igniter. If the burner is
fitted with secondary stoker, the device will be switched into AUGER EXTINCTION
(EMERGENCY SHUT DOWN) mode.
