Endress+Hauser Liquiphant FTL64 - Device Operation Methods; Overview of Device Operating Options; 4-20 mA HART Electronic Insert Controls

Operation options Liquiphant FTL64 HART
26 Endress+Hauser
7 Operation options
7.1 Overview of operating options
• Operation via operating keys and DIP switches on the electronic insert
• Operation via optical operating keys on the device display (optional)
• Operation via Bluetooth® wireless technology (with optional device display with
Bluetooth) with Smartblue app or FieldXpert, DeviceCare
• Operation via operating tool (Endress+Hauser FieldCare/DeviceCare, handheld terminal,
AMS, PDM, ...)

 20 Operating keys and DIP switches on the 4 to 20 mA HART electronic insert
1 Operating key for reset password (for Bluetooth login and Maintenance user role)
1+2 Operating keys for device reset (as-delivered state)
2 Operating key for "Proof test" wizard (> 3 s)
3 DIP switch for safety function, software-defined (SW, default = MAX) or permanently MIN (in the SW switch
position, the MIN or MAX setting is defined by the software. MAX is the default value. In the MIN switch
position, the setting is permanently MIN irrespective of the software).
4 DIP switch for locking and unlocking the device
• Minimum/maximum quiescent current safety can be switched at the electronic insert
• MAX = maximum safety: when the tuning fork is covered the output switches to demand
mode, e.g. use for overfill protection
• MIN = minimum safety: when the tuning fork is uncovered, the output switches to
demand mode, e.g. use to prevent pumps from running dry
The setting of the DIP switches on the electronic insert has priority over the settings
made via other operation methods (e.g. FieldCare/DeviceCare).
