NOTICE

ence value to the setpoint.
NOTICE
Should the option ’Control by Atmospheric Conditions’ be active, the setpoint cannot be
changed and saved via the front plate. These setpoints can only be changed by the PC Re-
mote Software (DLT1040) or with the GKI300 (DLT7106).
5.1.2 Operating Description
The burner start-up is carried out as described above. At least ’Burner ON’ signal and ’Re-
lease’ must be sent by firing rate controller.
The burner starts as soon as it is receiving signals ’Burner ON’ and ’Release’ from firing rate
controller. The firing rate controller is in operation not before the burner is running and the sig-
nal ’Control Release’ is pending.
The default value of firing rate for fuel/air ratio control is set via integral firing rate controller.
Depending on the difference between actual and setpoint value and adjusted control param-
eters this default firing rate value is set. When actual value is exceeding to maximum value
the firing rate controller switches OFF combustion.
The firing rate controller is active in AUTOMATIC mode only.
