When first installing the
blackbox
, or subsequently moving or using the unit
on a new application, before proceeding to program the unit for its intended
application it is recommended that you ensure that all parameters are at their
default values by completing a
Factory Defaults P930,
as described in
Chapter 5
Parameter Guide
.
When you first switch the
blackbox
on it will provide an output proportional
to the
distance
from the face of the transducer to the surface. All relays are
set OFF.
The
date
(P931) and
time
(P932) in the
blackbox
were set at the factory, but
may need checking, and amending if, for example the application is in a
time zone other than GMT, see Chapter 5
Parameter Guide
for full details.
TIP
In some applications it is simplest to empty the
vessel, take a reading from the
blackbox
for
distance and then setup the empty level to this
figure.
Once you are satisfied with the installation, and the
blackbox
is reading
what you would expect in terms of distance from the face of the transducer
to the material level, then you can proceed with programming, for the
intended application. It is sensible to program all of the required parameters
at the same time. The system will be then set-up.
Note that the span is automatically calculated from the empty level, so the
empty level should be entered first.
