TRANSDUCER WITH DUAL FLOAT BACK UP SYSTEM
If operating the auto start system using a transducer, you can install a single or dual set of floats
positioned at a critical high level that will start and run the pump at a programmable speed and for a
programmable length of time. This is an available option for backing up a level transducer installation.
A digital input must be assigned to the Float functions. When the engine is running under the failsafe
mode, the yellow LED will be illuminated and the display will indicate the mode.
If the high float closes before the level, as measured by the transducer, reaches the On setpoint, the
transducer will be considered failed and the engine will be started under the Backup mode as shown in
the screen below.
