Diagnostic Fault Codes; Corrective Action - Franklin Electric SubDrive Duplex Alternator Manual Del Usuario

Diagnostic (Fault) Codes
The red "Fault" light will flash a given number of times to indicate the operating
status. After a fault has been corrected, the alternator can be reset by holding
down the "Switch Pump or Clear Fault" button for 5 seconds or by removing
power. The alternator may also see that the system is functioning normally again
and self-clear the FAULT light and alarm. Fault codes and the recommended
corrective action for each are listed in the chart.

Corrective Action

Drive Fault: Check drive 1's front panel for
possible fault code and follow corrective
actions for that fault code. Make sure that
drive 1 has a green light (i.e. it has power).
Not Meeting Demand: Application has water
demand exceeding the ability of a single
drive to maintain constant pressure which is
a normal operating condition.
Lower Set Pressure is Shorted: Check
the lower set pressure sensor to see if its
contacts are shorted together.
Drive Fault: Check drive 2's front panel for
possible fault code and follow corrective
actions for that fault code. Make sure that
drive 2 has a green light (i.e. it has power).
Not Meeting Demand: Application has water
demand exceeding the ability of a single
drive to maintain constant pressure which is
a normal operating condition.
Lower Set Pressure is Shorted: Check
the lower set pressure sensor to see if its
contacts are shorted together.
Check the leads to the higher set pressure
sensor. Check the sensor itself. Check the
leads to alternator's terminal block.
Check leads from drive 1 to alternator. Check
connection at terminal block of drive 1 and
connection at alternator terminal block.
Check leads from drive 2 to alternator. Check
connection at terminal block of drive 2 and
connection at alternator terminal block.
Adjust pressure sensors so the psi difference
is great enough to get only one drive to
run at a time; at least 3 psi should be
enough difference.
