SP PRO Interactive Inverter Charger
Technical Note
DINGO Regulator Float
Integration
Introduction
The SP PRO and DINGO regulator can be connected and configured so that the
charging stage of the SP PRO will change to Float when signalled by the DINGO
regulator. This keeps both SP PRO and DINGO working to the same charge stage.

SP PRO Configuration

The SP PRO is configured by default to accept the Float input
on Digital Control Input 1. Float Stage Input would only need
to be changed from default if Digital Control Input 1 is being
used for another purpose.
This is set to accept the Float signal from the DINGO
regulator.

DINGO Regulator Configuration

The DINGO 'G' output can be set to give an active signal when it's in float.
SET/ PROG=4
NOTE: If changing from generic PROG=0,1,2,or 3, you should check that all the
settings under the SET/REG menu are correct for your application as these may be
different from the generic (PROG=0-3) settings.
SET/MODE/GSET=4 if using the 'G' terminal, as shown in diagram.
SET/EVNT...
STRT=0 (always starts)
STOP=0 (stop never active)
----- (the above settings have the effect of making the STRT and STOP irrelevant)
EMOD=1 (in float with Low Battery Disconnect override)
TMOD=0 (always active).
This is now set to signal the SP PRO when to change to Float stage.
