Internal Burner Firing-rate Controller
7.1
Purpose
The internal power control unit allows the inserted burner firing-rate position to be continually
determined for a specified set-point value (e.g. as a function of temperature or pressure) by
comparison with the actual value. This position will be transferred to the electronic compound
as a default value.
7.2
Brief Description
The integral power control unit is a PID controller with special combustion engineering func-
tions. You can use it as a fixed value control or as a control by atmospheric condition. The fol-
lowing signals can be pre-set:
•
Actual value (temperature or steam pressure)
•
Outside temperature or other analog signal for setpoint shift (only on control by atmo-
spheric condition). The ETAMATIC must be equipped with the optional hardware for con-
trol by atmospheric condition.
•
Setpoint switching (via floating contact). The burner-firing-rate controller releases the
combustion internally.
Combustion is triggered internally by the power control unit.
7.3
Limit Ranges
You must set limit values in the parameters, which switch the burner on and off. If the burner
shuts down and the actual temperature has not yet reached the switch-on threshold again, a
display informs the operator that the power control unit refuses a start-up.
7.4
Light Writing "Actual Temperature is too high"
NOTICE!
The limit values should always be entered in the form of a difference from the set-point value.
7.5
Enter setpoint of power control
Up to software version A3i1023 you can change the setpoint with parameterisation only.
From software version A3i1023 on you can change the setpoint of the firing-rate controller.
This function works only if the burner is in operation
Press key 12 HAND to override this and start the ETAMATIC, if the maximum temper-
ature has not exceeded.
Press key 12 HAND again to switch back to automatic mode.
Press key 9 and 6 simultaneously
the setpoint in the display is blinking.
Use keys 4 and 5 to change the value.
