Parameter Defaults
When you first switch the UltraTWIN on, it will be reading the
distance
from
the face of the transducer to the surface. It will be indicating in
metres
, as
shown on the display. All relays are set OFF.
The
date
(
P*931
) and
time
(
P*932
) in the UltraTWIN 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 relevant parameter listing
for full details.
In some applications, it is easier to empty the vessel, take a reading from
the UltraTWIN for distance and then setup the empty level to this figure.
Once you are satisfied with the installation, and UltraTWIN 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:
The span is automatically calculated from the empty level, so the
empty level should be entered first.
Factory Defaults
When first installing the UltraTWIN, 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 Default
P930,
as described in the relevant unit type
parameter guide
