ON pulse is shortened/interrupted
and replaced by UV and OFF pulse
OFF pulse is activated until both
feedbacks return to the correct
po2 seconds.
CB fail
– If any inconsistence
between the two feedback signals is
detected, CB fail is issued. Fail is
active until Fault Reset is pushed.
Further behavior of UV output depends on the system
status. In case of transition to cooling stays off, if the Cb
was opened manually and the engine keeps running, it
activates again after timeout elapses.
