ETTING REVERSE FEEDING AND IGNITION TEMPERATURE
• Delay reverse movement
This submenu is used to change the delay in the reversal of the
feeding system. The feeding system reverses for overcurrent if the
rotary feeder becomes blocked. The change of rotational direction is
then delayed by this amount of time.
• Reverse moving runtime
The running time of the backward running of the feeding system can
also be corrected. This value is limited to a maximum of three
seconds.
• Reverse moving attempts
Setting the maximum number of reverse moving attempts.
• Ignition temperature
If the temperature in the hot combustion chamber exceeds this
value, the HDG Control does not switch on the ignition fan for
starting the heating system.
