Notes:
1. Pump Down Applications (Parameter P.19 = 1)
Two Float Backup - A simple two float backup system can be made using an
Off float and a High float.
High Level Input - Closure of the Float Backup High Level input will cause all
pumps to be called to run, provided the Off float input is closed. The Discrete
Input used for the High Level must be set on Function 38.
Low Level input - Closure of the Low Level input will disable all pump
operation. When the Low Float input opens, a delay prevents the immediate
calling of the pumps. This delay is set on Parameter P37. The Discrete Input
used for the Low Level must be set on Function 32.

High floats must be normally open float switches that close as the level rises
above the float. The Low Level float must close as the level drops below the
float.
2. Pump Up Applications (Parameter P.19 = 2)
Two Float Backup - A simple two float backup system can be made using an Off
float and a Low float.
Low Level Input - Closure of the Float Backup Low Level input will cause all pumps
to be called to run, provided the Off float input is closed. The Discrete Input used
for the Low Level must be set on Function 32.
High Level Input - Closure of the High Level Float switch will disable all pump
operation. When the High Float input opens, a delay prevents the immediate
calling of the pumps. This delay is set on Parameter P37. The Discrete Input used

3. The FAULT light comes on and Fault Code 16 is generated, when a pump is
called to run by the Float Backup system.
