Figure 4-14. Setup procedure for the Rosemount Tank Gauging Safety System
STEP 1
DEVICE VERIFICATION
Verify that correct equipment is installed and configured
and that the surface level is at least 1 meter below the SIL
High Alarm Limit.
For dry-run applications the surface must be a maximum of
125 mm above the SIL Low Alarm Limit.
STEP 2
CALIBRATION OF SURFACE
Adjust the SIL Amplitude Threshold until the 5900
gauge finds the product surface.
If needed, use the SIL Calibration Distance for minor
adjustments to match actual distance to product
surface with measured distance.
LPG/LNG only: reset filtering of Verification Pin.
LPG/LNG only: filter out the Verification Pin.
STEP 3
FINAL ADJUSTMENT OF AMPLITUDE THRESHOLD
Adjust SIL Amplitude Threshold to increase Signal/Noise ratio.
STEP 4
VERIFICATION OF SAFETY ALARM PARAMETERS
Verify that all safety parameters are correct before
approving the Rosemount Tank Gauging Safety System.
STEP 5
MAKE A BACKUP COPY
Make a backup copy of the gauge configuration database
(use the TankMaster WinSetup “Save Database to File” option
to store Holding and Input Registers).
