The significance of the red LED (fig. 2 2, page 3)
For operational faults it illuminates several times. The number of pulses depends on
the type of fault.
Each flash lasts for one quarter of a second. After the series of impulses a pause
follows. The sequence for the fault is repeated every four seconds.

than 1 A.
time
The pressure difference in the cooling system
is too high (> 5 bar).
