Level System Synchronization
When using multiple ultrasonic level monitors, be sure to run the transducer cables in
separate grounded metal conduits.
When separate conduits are not possible, synchronize the level monitors so that no unit
transmits while another is waiting for echo reception.
Synchronizing with another HydroRanger 200, or other Siemens Milltronics
instruments (DPL+, SPL, XPL+, LU01, LU02, LU10, LUC500, Hydro+,
EnviroRanger, MiniRanger):
• Mount the level monitors together in one cabinet
• Use a common power (mains) supply and ground (earth) for all units
• Interconnect the SYNC terminals of all level monitors
•Set parameter
P726 Level System Sync
on page 190.
• Contact Siemens Milltronics or your local distributor. Go to
www.siemens.com/processautomation.
