7.8 Commissioning
The following equipment may be used for commissioning:
•HART
®
-Communicator
• The PC-based control software LB 480-PC.
For commissioning, you should be familiar with the operating
instructions (Level, Limit Level, or Density).
Carry out the following steps for commissioning:
1. Calibration (see User's Manual Volume 3, Chapter 5)
2. Enable Safety Mode
Menu path: Device Config>Access>Safety ON
With this setting, the security-compatible setting is checked
and the detector LB 480 locked.
The Safety Mode is maintained even if the device is turned off
and then on again.
3. Check safety parameters and measured value
Menu path: Diagnostic>Safety>Refresh Safety Status
– First update Safety Stati.
To do this, select parameter "Refresh Safety Status".
– Then Safety Status 1, 2 and 3 have to show the value 0xFF.
If not, the measurement cannot be used in a protection device.
The measurement can be used in a protection device only when
the settings are corrected so that 0xFF is displayed in the active
"Safety Mode". If you need help, please see the brief explana-
tion in the safety parameters in each menu of Safety Status 1,
2 and 3.
Please refer to chapter 7.9 "Periodic Inspections" so that the refer-
ence values for this test can be determined directly following the
commissioning.
