Table 4-10. Example of how to configure the SIL High Alarm Limit
The calculated SIL High Alarm Limit in this example is 2620 mm. This is well above 625 mm
which is the minimum value that can be used for a Parabolic antenna at a maximum level rate of
2 mm/s as given by Tabl e 4- 9.
In case the SIL Hold Off Distance is adjusted, the SIL Hold Off Distance Adjustment value (see
Tab le 4- 13 ) must be added to the minimum value given by Ta ble 4 -9 .
