Burner hours run stage 1 (tBR1)

Auxiliary value for ascertaining the amount of energy consumed.
Display
0...65535
The current number of hours run of burner stage 1 or of a BMU will automatically be
displayed on this line.
1.22.1

Counting the hours run

The hours run of burner stage 1 are counted based on the signal received from output
K4. The voltage of the output signal is AC 230 V.
Each time 2 full operating hours are registered, the new value will be written to non-
volatile memory. Only full hours are displayed, and no minutes.
This means that if the display is checked again after a short period of time, it may still
show the previous reading, if the burner has not yet completed another 2 operating
hours.
When using a BMU, the value transmitted will be displayed via PPS.
1.22.2

Average burner running time

Together with the display of the number of burner starts ( line 37), it is possible to
ascertain the average burner running time.
This information makes it possible to determine if:
−
the plant is correctly sized
−
the burner has become dirty
