Faults
Transducer Level Low-Level Switch High-Level Switch Result
Above Low-Level Point Open — Transducer is within normal
operating range, but value is
incorrect (too high) because low-
level float should be closed
Below High-Level Point — Closed Transducer is within normal
operating range, but value is
incorrect (too low) because high-
level float is closed
Out of Range (Low) — — Transducer value is below the
normal operating range (severe)
Out of Range (High) — — Transducer value is above the
normal operating range (severe)
6.4.3 Configuring the Transducer
With a transducer connected, the CP750-E can be configured to throttle the engine to maintain a specific
transducer level much like a car’s cruise control. If this cruise control feature is desired, the Maintain Transducer
Level should be set to Enabled. The other choice is Disabled, which follows the Ramp Profile described in the
Ramp Profile section.
The transducer’s cruise control function can be independently set to either Low to High or High to Low.
Function Throttles Up When Throttle Down When
Low to High Input is below the target point Input is above the target point
High to Low Input is above the target point Input is below the target point
To see or change the transducer target point, go to the
Autostart → Maintain Transducer Level → Target Point
menu.
Some applications are slow to respond to throttle changes while others are fast. An analogy is a car’s cruise
control and how the car reacts going downhill or uphill. Going downhill, a car will quickly speed up when just a
little more throttle is applied. In this case, the throttle adjustment should be less aggressive. On the other hand, a
