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.

Note: To synchronize the SITRANS LU01 with other Siemens Milltronics ultrasonic level monitors, contact Siemens Milltronics or your local distributor.
