Factory Defaults
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 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.
