Level system synchronization
When transducer cables are run parallel with each other, synchronize the level monitors
so that no device transmits while another is waiting for echo reception. If more than one
ultrasonic device is being installed in the same application, the devices must be
synchronized to prevent cross-talk. Optionally, the transducer cables can be run in
separate grounded metal conduits.
Synchronizing with another SITRANS LUT400, or other Siemens devices
Other Siemens devices that can be synchronized with the SITRANS LUT400:
DPL+, SPL, XPL+, LU01, LU02, LU10, LUC500, DPS300, HydroRanger 200,
HydroRanger Plus, EnviroRanger, MiniRanger, MultiRanger 100/200
• Mount the level monitors together in one cabinet
• Use a common power (mains) supply and ground (earth) for all devices
• Interconnect the SYNC terminals of all level monitors.
• Up to 16 Siemens devices can be synchronized together.
