Description   
[Autonomous 
SAT enable] 
[SAT enable] 
(Displ. level) 
SAT 
enable up 
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. 
[SAT raise 
height up] 
-  0.02 m  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. 
[SAT raise 
height down] 
-  0.02 m  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. 
[SAT interval 
time] 
-  60 min  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). 
[SAT weight 
limit up] 
-  0.005 kg  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]. 
[SAT weight 
limit down] 
-  0.005 kg  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].
