7.3.1.3 Max. fuel s.
Menu / Startup / Stokerscrew / Max. fuel s.
The basis setting is 75 % of maximum operating time indicated in chapter 7.2.2.3
When the boiler is in start-up mode, it is important that the burn head will not be overfilled with fuel. The
settings in this parameter can prevent that.
It is very important, that the value is not to high, especially if the boilers run on wet og other bad fuel.
7.3.2 Oxygen.
Menu / Startup / Oxy
To make sure that the controller knows if the fire is on or if the ignition should be activated, there is some
limit values for the O
2
, that have to be set.
7.3.2.1 Go to startup O
2
%
Menu / Start-up / Oxy / Go to start-up O2 % (16%)
Normally the 16-17 % are basis for this parameter.
If the O
2
is over the indicated value, the controller will go in start-up mode and activate the automatic
ignition if such is mounted, If not the fan will start pulsing to ignite the fire.
More detailed instructions for automatic ignition, are written in chapter 5.
7.3.2.2 Oxy. differens
Menu / Startup / Oxy / Oxy. Difference (2%)
With Automatic Ignition use the value 1,5%, and with no ignition use the value 2,0%
When the controller are in start-up mode, this parameter control when the controller recognize that there
are fire in the burn head again.
How it works depend on, do the boiler have Automatic ignition, or not.
With no ignition the boiler will switch to run mode, when the O
2
level is below
Go to start-up O2 % -
Oxy. Difference (16%-2%) < 14%
Instructions for how it works with automatic ignition, go to chapter 5.
7.3.3 Smoke temperature.
Menu / Start-up / Smoke temp
The smoke temperature is helping to inform the controller if the fire is properly ignited or if the boiler
needs to be cleaned.
7.3.3.1 Go to run mode °C
Menu / Start-up / Smoke temp / Go to run mode C (30°C)
Normally we don’t use this function, at set it to 30° C.
If the boiler run without O
2
sensor, it is possibly to use the smoke temperature, to recognize if the fire is
on, and the controller can switch into run mode.
7.3.4 Startup time min.
Menu / Startup / Startup time m. (20 min.)
In connection with startup of the boiler it is allowed that the boiler uses a specified time to bring the O2
down below the value which is indicated in chapter 3.3.2.2. If it does not succeed within expiration of the
start-up time, the boiler goes into “start-up timeout”.
Depending on the fuel and the type of the boiler the time is set so the boiler has a chance to bring the O2
down without going into alarm mode.
