Preliminaries

WARNING
L
The settings of the current output are relevant for safety!
Incorrect settings may cause the product to overflow or a pump to run dry.
‣
The setting for the current output depends on the setting in the Assign PV parameter.
‣
After changing the setting of the current output: check the settings for the range
(Lower range value output (LRV) and Upper range value output (URV)) and reconfigure
them if necessary!
9.1.1

As-delivered state

If no customized settings were ordered:
• Assign PV parameter Level limit detection (8/16 mA mode)
• MAX safety mode
• Alarm condition set to min. 3.6 mA
• DIP switch for locking in OFF position
• Bluetooth switched on
• Density range > 0.7 g/cm³
• Switching times 0.5 s when the fork is covered and 1.0 s when it is uncovered
• HART burst mode switched off
9.2

Function check

Before commissioning the measuring point, check whether the post-mounting and post-
connection checks have been performed:
• Checklist in "Post-mounting check" section
