THOMPSON PUMP J1939 - Fail-Safe Float Start;Stop; Dual Float Back-Up Operation

- 4 -
FAIL SAFE FLOAT START/STOP
An optional fail safe float can also be used as a backup to the transducer. To enable the failsafe float:
In the Auto Operations Menu
1) set Failsafe Float to “ON”
2) set the Failsafe Speed to “Desired engine speed if fail safe float is tripped”
3) set the Failsafe Float Time Delay for “the minimum amount of time the engine runs if the
failsafe float is tripped”
DUAL FLOAT BACK-UP OPERATION
An optional dual float back-up operation is available when utilizing the application transducer for the
pump start/stop. To enable this function:
In the Auto Operations Menu
1) set Start/Stop Input to “Transducer & Floats”
2) set the Dual Float Speed to “Desired engine speed if dual float is tripped”
In this mode, when the level reaches the dual float trip point, indicating transducer failure, the pump
will continue to run in a single speed mode under standard dual float operation.
