5.3.4 Connecting level switch and temperature switch
Level switch duty cycle
Dropping hydraulic uid level:
If the amount of hydraulic uid removed during each duty cycle causes the oil level to fall below
the level switch’s monitoring level, take suitable electrical measures to mute the signal until the
uid level rises above the monitoring level once again when the hydraulic uid ows back in at the
end of the duty cycle.
