Abstract:
A method for monitoring a function of a safety unit, in particular of a bilge blower of a boat with a combustion engine, connected via a manually operated switch to a voltage supply. The current flowing through the safety unit is measured and an acoustic alarm is triggered, if a sensor voltage derived from the measured current falls below a reference voltage.
