burners with electronic components are always equipped with:
a) Gas damper with separate servomotor and feedback potentiometer
b) Air damper with separate servomotor and feedback potentiometer
c) Frequency converter, which controls the burner motor speed in accordance with the relevant load po-
sition point
d) Speed transmitter, which ensures feedback of the motor speed to the automatic gas control box.
As a rule, all these positions are allocated to each other and set up in such a way during the configuration
of the electronic components that the burner will perform with optimised hygiene between the various load
point positions (min. 200 digits, max. 999 digits).
11.2 Adjustment of the operation distance of the speed transmitter
When setting the speed transmitter, the following operating distances must be maintained:
Operating distance for motors up to 11 kW:
2 mm
Operating distance for motors from 18,5 kW:
5 mm
