Connecting a pump to the Delta Battery Backup
4.5.1
Connecting an automatic pump to the Delta Battery Backup
All standard Delta packaged
pumping stations that are
compatible with the Delta Battery
Backup feature automatic pumps
(pumps which come with a float
already attached).
•
Delta V3 Pump
•
Delta V4 Pump
•
Delta V6 Pump
•
Delta Foul V3 Pump (Automatic)
These connect to the UL/UN
(Direct Load) terminals.
In operation, there will always be
a voltage across these terminals.
The pump's integral float switch will
activate the pump.
4.5.2
Connecting a manual pump to the Delta Battery Backup
Should you need to connect a
manual pump to the Delta Battery
Backup, use the AL/AN (Aux
Load) terminals instead of the
UL/UN (Direct Load) terminals.
The level control (float, pressure
switch etc) which controls the
pump should connect to the Aux
Contact terminals.
When the Aux Contact terminals
are closed by the activated level
control, a voltage is applied
across the AL/AN terminals thus
powering the pump. When the
level control deactivates, the Aux
Contact is opened and the pump
is de-powered.
