Description
When set to 'SAT enable up' a SAT will be
started roughly 1 minute after tank loading has
apparently stopped. The SAT will only raise and
lower the displacer.
When set to 'SAT enable up + down' a SAT will
be started roughly 1 minute after tank loading or
offloading has apparently stopped. The SAT will
alternately raise the displacer above the liquid
level or lower the displacer beneath the liquid
level. For more details refer to 954 SmartServo
FlexLine Safety manual.
Furthermore, when one of the SAT enables is
selected, the SAT will be executed at regular
intervals.
When set to 'SAT disable' there will be no
automatic SAT at all. The operator can however
start a SAT by manually entering the
'SAT upwards' or 'SAT downwards' command.
With this entity the operator can configure the
height over which the displacer is raised during
the SAT upwards. For a successful SAT the
displacer needs to be lifted entirely above the
liquid.
With this entity the operator can configure the
height over which the displacer is lowered during
the SAT downwards. For a successful SAT the
displacer needs to be immersed entirely in the
liquid.
With this entity the operator can configure the
time between two consecutive SATs. The
minimum value is 1 minute, the maximum value
is 40320 minutes (28 days).
During the SAT upwards, the weight of the
displacer is measured and checked against the
expected weight (entity [Displacer weight]). The
measured weight must be smaller than
[Displacer weight] + [SAT weight limit up].
During the SAT upwards, the weight of the
displacer is measured and checked against the
expected weight (entity [Displacer weight]). The
measured weight must be larger than
[Displacer weight] - [SAT weight limit down].
