8 Commissioning
8.1 Function check
Before commissioning the measuring point make sure that all final checks have been carried out:
• Checklist “Post-installation check”, (® ä 12)
• Checklist “Post-connection check”, (® ä 13)
8.2 Switching on the transmitter
Once the final checks have been successfully completed, it is time to switch on the supply
voltage. The 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" text and firmware version of the display
2 Firm logo
3 Device name with firmware and hardware versions
4 Information on the sensor configuration (sensor element and type of connection)
5 Set measuring range
6a Current measured value or
6b Current status message
If the switch-on procedure is not successful, the relevant diagnostics event, depending on the cause, is
displayed. A detailed list of diagnostic events and the corresponding troubleshooting instructions can be
found in the "Diagnostics and troubleshooting" section (® ä 27).
The device is operational after approx. 8 seconds, and the plug-in display after approx. 12 seconds
in normal operating mode! Normal measuring mode commences as soon as the switch-on
procedure is completed. Measured values and status values appear on the display.
8.3 Enabling configuration
If the device is locked and the parameter settings cannot be changed, it must first be enabled via
the hardware lock. The device is locked using the hardware if the keyhole symbol appears in the
header of the measured value display. To unlock the device, switch the write protection switch
on the back of the display to the "OFF" position (® ä 21).
