Fan temperature input is set up in parameter 6561, and this input can be selected between these inputs:
• Three multi-inputs in slot #7 are available
• EIC measurement (engine interface communication)
• External analogue input 1-8 (H12.X)
• Analogue inputs (M15.X)
• Multi-inputs (M16.X)
The multi-inputs can be configured to, for example, a Pt100 sensor that measures an engine- or ambient temperature. If EIC is
selected, this is defined as the highest measured temperature of either cooling water or oil temperatures.
Based on the measurement of the selected input, the fan(s) are started and stopped.
6.6.3 Fan start/stop
The start and stop settings of the fan(s) are set up in parameters 6563 to 6574. With the settings in the table below, the illustrative
curve can be observed.
A hysteresis (abbreviation: hyst.) ensures that there is a range between the start and stop.
The following start/stop curve will be generated if a bow setting is used:
