Corrections
26.1 Correct any problem with the mineral
free water inlet
26.2 Replace blown fuse.
26.3 Replace the DIG-T2 board
26.4 If approximately 120VAC is present then
the pump is faulty and should be
replaced. If no voltage is present then
replaced the AC-T1 board.
26.5 Clear any clog and / or replace the filter.
26.6 Replace faulty float switch.
27.1 Replace the DIG-T2 board.
27.2 With the JP1 removed if the pump
continues running then replace the
AC-T1 board. If it stops then replace the
ANL-T2
27.3 Fix connection.
Possible cause check-up and tests
26.1 Check that the water pump reservoir is
full and mineral free water will flow in
freely.
26.2 Check the fuse at the rear of the unit.
26.3 Check TP17 if the voltage is constantly
<1VDC then the problem is on the
DIG-T2 board.
26.4 If the voltage at TP17 is higher than 4DC,
then remove the JP7 connector and check
the output of JP7-2 on the AC-T1 board to
ground.
26.5 The pump has stopped due to a clogged
water pump filter
26.6 The lower float in the vacuum pump
reservoir may be faulty, stopping the
pump.
The problem may be a failure of the control
circuit on the DIG-T2 board or the driver
on the AC-T1 board.
27.1 Check TP17. If the voltage is higher than
4V then the DIG-T2 board is faulty.
27.2 If the voltage at TP17 is <1VDC the
problem is either the AC-T1 board or the
ANL-T2 board. Turn off power and
remove the JP1 connector on the AC-T1,
turn power back on
27.3 Upper level electrode control wire is
disconnected or electrode does not sense
water (see sec 10.4.21).
