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 MultiRanger 100/200, or other Siemens Milltron-
ics instruments (DPL+, SPL, XPL+, LU 01, LU 02, LU 10, 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
• Contact Siemens Milltronics or your local distributor. Go to
www.siemens.com/processautomation.

Note: The MultiRanger 100/200 CANNOT be synchronized with the MultiRanger
Plus or the HydroRanger.

Important!
Before applying power to the MultiRanger for the first time, ensure any connected
alarm/control equipment is disabled until satisfactory system operation and
performance is verified.
Notes for AC power connections
• The equipment must be protected by a 15 A fuse, or circuit breaker in the
building installation.
• A circuit breaker or switch in the building installation, marked as the disconnect
switch, must be in close proximity to the equipment and within easy reach of the
operator.
