8.7.4 Suggested comprehensive, fully remote proof-test
Suggested comprehensive, fully remote proof-test with
Rosemount Radar Master
The suggested proof-test described below will detect 85% of possible DU failures in the
Rosemount 5300 Level Transmitters.
Procedure
1. Bypass the safety function and take appropriate action to avoid a false trip.
2. Disable write protection in device (if enabled).
a) Select Tools → Lock/Unlock Configuration Area.
b) Enter password to unlock.
3. Using Loop Test, enter current value (mA) representing high alarm current. Verify
that analog output current is correct using the reference meter.
a) Select Setup → Output → Analog Out 1 and click Loop test.
b) Enter current value representing high alarm current.
c) Click Start to output current.
d) Verify that analog output current is correct.
e) Click Stop to end loop test.
4. Using Loop Test, enter current value (mA) representing low alarm current. Verify
that analog output current is correct using the reference meter.
a) Select Setup → Output → Analog Out 1 and click Loop test.
b) Enter current value representing low alarm current.
c) Click Start to output current.
d) Verify that analog output current is correct.
e) Click Stop to end loop test.
5. Enable write protection.
a) Select Tools → Lock/Unlock Configuration Area.
b) Enter password to lock.
6. Perform a one-point level measurement verification of the device. Verify the current
level measurement with an independent measurement such as the BPCS level-
sensor or a manual reading.
7. Remove the bypass and otherwise restore normal operation.
