Specications
The Model CP-5
is an undercurrent monitor designed to monitor
one leg of a 3-phase system. It is commonly used as
a tower monitor on center pivot irrigation systems
to detect stalled or jammed towers to prevent
overwatering.
The CP-5 has both an adjustable trip level and an
adjustable trip delay timer. When the current is
sensed, the Model CP-5 activates its output relay,
thus starting the motor/pump. When the current
in the monitored power line falls below the user-
selectable trip point, the unit goes through a trip
delay timer and then deactivates the output relay if
the monitored current does not recover first.
For more information see:
See Appendix A, page 68, Figure 7 for dimensional
drawing.
See Appendix B, page 81, Figure 52 for typical
wiring diagrams.
