Output hold
For eliminating
undesirable output switches,
additional parameters
(Hold On and Hold Off)
are assigned to hold
the output reaction
for certain period of time.
Output pulse mode
When an output is activated
by the control algorithm, it
can either stay ON or pulse
depending on Time On and
Time Off parameter values.
♦
In some cases, BBI250
finds discrepancies
in parameter values
that must be resolved
before operating
at Basic level.
♦
The device indicates
such kind of problems
by displaying
error messages
as given on the left.
♦
If FAL appears
on the display,
try debugging
by turning
the power off/on.
♦
If the problem persists,
press and hold
to restore the default
(factory) settings.
