off: No error, no warning
flashes: Warning is present, pump can be
operated, possibly with some restrictions
on: Fault is present, pump stopped or
can not be operated
Yellow LED PWR
off: No supply voltage
flashes: Supply voltage too low or too high,
9 Hz <n <100Hz (venting possible)
on: Supply voltage is present
