measurement range. To reset the alarm -
switch OFF and ON the regulator. Check the
sensor and replace, if necessary.
Checking temperature sensors
described in this manual, in
point.12.8.
15.7
Unsuccessful firing up attempt
This alarm occurs after the third unsuccessful
automatic furnace firing up attempt. The
reason behind this alarm occurrence can be
among other things: malfunctioning igniter
or ventilator, malfunction of fuel feeder
system,
incorrect
parameter
setting,
insufficient fuel quality or lack of fuel in the
container.
The alarm can be reset by restarting the
power supply.
Attention!
Before
work
continuation it is required to
check, if in the combustion
chamber there was a large
accumulation of unburned fuel. If
it is the case, than it is required
to remove this excessive fuel.
Firing the boiler with an fuel
overdose
can
lead
to
an
explosion of combustible gases!.
15.8
Exhaust temperature not met.
Check fuel quality
This alarm is sounded when the exhaust
gases are not heated above the lack of fuel
detection
threshold
in
the
exhaust
temperature increase time. The alarm
prevents filling the combustion chamber with
unburnt fuel. Check the quality and moisture
of the fuel.
The alarm can be reset by restarting the
power supply.
15.9
Boiler overheating STB, open
contact
This alarm occurs after activation of
independent safety thermostat that secures
the boiler against overheating. The burner
will then be deactivated. After the boiler
temperature will drop down it is required to
unscrew an oval STB lid and then press the
Reset button.
15.10
Max exhaust temperature
exceeded. Sensor damage danger!
This alarm occurs only when using the
GRATE and exceeding the maximum exhaust
temperature. The fan is turned off. Its aim is
to protect the exhaust temperature sensor
from being damaged by temperatures
exceeding its resistance level. When the
temperature on the boiler drops, the
regulator returns to normal operation.
The alarm can be reset by restarting the
power supply.
15.11
No communication
The control panel is being linked with the
rest of the electronics with RS485 digital
communication link. In case a cable of this
link will be damaged, an alarm will occur on
the screen with the information “CAUTION!!!
No communication”.
The controller doesn’t stop to operate and
works
normally
with
before
preset
parameters. It is required to check the
connection cable between control panel and
the module and replaced it with a new one or
repair it.
15.12
Unsuccessful attempt of
buffer loading
This feature has an application only after
module B connection. It is a silent alarm,
which informs about unsuccessful attempt of
adding fuel from additional fuel container
(bunker) to boiler container. In case, when
during preset time of container loading, a
sensor in this container will not detect the
increase of fuel level, this alarm will occur.
This signalisation does not shut down boiler
automatic operation.
15.13
No power supply
This alarm occurs after power to the
regulator, in the case of early no power
supply. The regulator returns to the mode of
operation where worked before the power
failure.
15.14
Fan or fan speed sensor
damaged
This alarm occurs then the fan’s speed
sensor or the fan itself is damaged, based on
the voltage capacity on the terminal
