Activating the lubrication and detecting lubrication errors
The recommendation is to send 5 pulses (10s) to the lubrication pump every 5 min
or until the sensor responds. The sensor response at a successful lubrication is
to change the output value twice. The initial output value can be either 0 or 1. This
gives two scenarios for a completed sensor feedback: 0-1-0 or 1-0-1. In other words,
a correct sensor feedback after a completed lubrication cycle will be that the sensor
is changing the output value twice.
If no response has been received from the sensor after 5 pulses and 25 min, an
error has occurred.
