Chapter 5. Commissioning
5-1. Function check
Before commissioning the measurement point make sure that all final checks have been
carried out:
Checklist “Post-installation check”
→
Checklist “Post-connection check”
→
Note: The Foundation Fieldbus interface's technical data must be maintained in accordance
with IEC 61158-2 (MBP).
The bus voltage of 9 to 32 V and the current consumption of approx. 11 mA at the
meas.uring device can be checked using a normal multimeter.
5-2. Switching on the measuring device
Once the final checks have been successfully completed, it is time to switch on the supply
voltage. The head transmitter performs a number of internal test functions after power-up. As
this procedure progresses, the following sequence of messages appears on the display:
Step
Display
1
Display name and software (SW) and hardware (HW) version
2
Company logo (if applicable)
3a
Device name (if applicable) as well as the SW, HW and device release of the
head transmitter
3b
Displays sensor configuration
4a
Current measured value or
4b
Current status message
If the switch-on procedure fails, the appropriate status message is displayed,
depending on the cause. A detailed list of the status messages, as well as the
measures for troubleshooting, can be found in Chapter 7 “Troubleshooting”.
The device is operational after approx. 8 seconds and the attached display after approx.
12 seconds! Normal measuring mode commences as soon as the switch-on procedure is
completed. Various measured values and/or status values appear on the display.
