Checking the outputs (actuators)
Danger
Incorrectly connected actuators can cause dam-
age to the system.
During the actuator tests, check the respective
actuator carefully.
Danger
Activated charging devices (feed screw con-
veyor, screw conveyor, etc.) can cause block-
ages in the fuel discharge system during the
actuator test.
Activate charging devices only briefly.
The following actuators can be switched "manually"
Depending on boiler size and settings, other actuators
may be available.
"General"
■
"Central fault Open"

Examples of "function and logic":
■
Are the temperature values of the sensors in the nor-
mal range?
■
Is the state of the maintenance cover (open or
closed) correct?
Is the state of the light barrier (free or interrupted)
■
correct?
Residual oxygen content OK?
