6.3. SELECTION OF HOUR COUNTING METHOD
The unit offers the possibility of incrementing hour counters with a variable coefficient,
depending on air end temperature.
The use of variable coefficient is selected with P89 Variable Hour counting coefficient. If
this parameter is 0, all service and hour counters will increment with a fixed coefficient of
1.00.
If Variable Hour Counting is activated:
Running on load:
below 90 °C, coefficient = 1.00
between 90 and 95 °C, coefficient = 1.50
between 95 and 100 °C, coefficient = 2.00
above 100 °C, coefficient = 3.00
Running off load
below 90 °C, coefficient = 0.50
between 90 and 95 °C, coefficient = 0.75
between 95 and 100 °C, coefficient = 1.00
above 100 °C, coefficient = 1.50
These coefficients apply to both service and compressor
hour counters.
