Biopel MINI - Installation and Operation Instructions
35
1.1.1 Blow-out time
Time for cleaning the burner grate before dosing pellets for Ignition. Linked to the
function Blow out Speed and Ignition Delay.
30s
1.1.2 Blow-out speed
Speed of the fan when cleaning the burner. Linked to the function Blow-out Time.
100%
1.1.3 Hopper time
Amount of pellets for automatic ignition. It is recommended in the range of 12-18s,
depending on the burner type. Too few or too many pellets may cause too long or failed
ignition.
12-16s
1.1 Ignition delay
During this time, the external feeder will not be in operation to avoid blowing out the
pellets supplied for automatic ignition. Linked to the function Blow-out Time.
30s
1.1.5 Feeding time
Internal feeder operation in the burner during ignition. Internal feeder feeds the residual
amount of pellets from the back of the burner to the grate at regular intervals.
Connected to the Feeding Pause function.
5s
1.1.6 Feeding pause
Pause feeding of the internal burner feeder. How long the internal feeder is number
stand-by mode before the next feed. Connected to the Feeding Time function.
100-300s
1.1.7 Fan speed
Fan speed during the first half of the auto-ignition. The fan has a lower speed to create
the glow from which the fire is subsequently produced. Connected to the Heater
Protection function. The correct fan speed is related to the burner size. For more
information, please read the chapter Factory Settings.
1-8%
1.1.8 Fan 2 speed
Fan speed in the second half of the ignition process. If the flame has not been created
during the first half of the ignition cycle, the fan will increase its speed to create one.
Connected to the Heater Protection function. The correct fan speed is related to the
burner size. For more information, please read the chapter Factory Settings.
3-16%
1.1.9 Heater protection
Maximum time of one ignition cycle. During this cycle, the fan speed is graded according
to the Fan Speed and Fan Speed 2 settings. If ignition does not occur, the external feeder
will feed half the pellet load set in Feeding Time and try two ignitions. If there is no flame
during the time set in this function, an error message occurs and the boiler shuts down.
In case this time reaches 0 and despite this the pellets fail to ignite, the feeders will feed
a second, half dose of fuel (half of the value set in the Feeding Time function). It makes a
second attempt to ignite. If the time interval reaches 0 again without ignition (no flame)
(the photosensor does not detect light higher than the value set in the function
Brightness of ignition), then the alarm message "Failed ignition" is shown.
12min
1.1.10 Ignition brightness
Photosensor sensitivity. You can see the actual detection of the amount of light in the
bottom left corner after entering this function. If there is no flame in the boiler, the set
number must be higher than the number detected by the photosensor in the bottom left
corner. After successful ignition, the photosensor detects a flame and the light level will
increase and exceed the set limit. At this point, the ignition phase switches to PID
operation.
38
1.1.11 Fan delay
Igniter re-heating. The fan is deactivated for a set period of time after ignition activation
to prevent the igniter from cooling down. After the igniter has warmed up, the fan starts.
Fan delay after the ignition depends on this function.
30s
1.1.12 Min. power of the
heater
Here you can reduce the igniter's supply voltage. With the standard igniter supplied by
OPOP, we recommend leaving the original setting.
0
1.2 Operating parameters
Operating parameters for the operation of the external feeder and fan during so-called
PID operation.
1.2.1 Minimum power
Operation setting, pause of the external feeder and fan speed for the minimum boiler
power. Ensure that the flame is large enough to avoid poor flame detection or flame
extinction.
1.2.1.1 Maximum feeder
pause
Feeder pause at min boiler power. Depends on boiler size.
7-25s
1.2.1.2 Min. feeder
operation
Feeder operation during minimum boiler power. Depends on boiler size.
1-3s
1.2.1.3 Min. fan speed
Operation
Speed of fan rotation during minimum boiler output. Depends on boiler size.
