Transducers; Relays - Siemens HydroRanger 200 Instruction Manual

Transducers

Warning: Hazardous voltage present on transducer terminals during
operation.
Run the transducer cable in a grounded metal conduit, separate from other
wiring (except TS-3 temperature sensor wiring, if applicable).
Notes:
• Do not use coaxial cable because of electrical noise interference
• Do not connect the shield and white transducer wires together; wire to separate
terminals
• Disregard older transducer manuals that recommend these practices
A 0.1 µF (100V or greater) capacitor is included with the HydroRanger 200 for retrofitting
old HydroRanger installations. Please see
HydroRanger Installations)
