Wiring
Transducers
A 0.1 µF (100V or greater) capacitor is included with the HydroRanger 200 for retrofitting
old HydroRanger installations. Please see “HydroRanger 200 Installation (for retrofitting
HydroRanger Installations)” on page 235.
Relays
Relay contacts are shown in the de-energized position. All relays are handled identically
and can be configured as positive or negative logic using P118.
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
