Level System Synchronization
Avoid mounting the SITRANS LU01 near another ultrasonic level monitor. Likewise, when
more than one monitor is installed within a single plant/facility, ensure the transducer
cables of each system are run in separate grounded metal conduits. If this system
separation is impractical, or if measurement difficulties are encountered, system
synchronization may be required.

Synchronize the SITRANS LU01 with another SITRANS LU01
1.
Mount the level monitors together in one cabinet.
2.
Ensure the level monitors share a common power (mains) supply, and ground
(earth).
3.
Interconnect the SYNC terminals of the level monitors to be synchronized.
Notes:
•
The communication protocol is automatically detected by the SITRANS LU01
and shown via LED on the motherboard.

•
Ground shield at one end only.
Note:
To synchronize the SITRANS LU01 with other Siemens Milltronics
ultrasonic level monitors, contact Siemens Milltronics or your local distributor.
