Troubleshooting
The controller has LED indicator
lamps that facilitate isolating a
problem to the controller or to an
external device. There are 4 green
LED=s, DS5-DS8, located next to
the input terminal strop P2. When an
LED is on, this indicates that the
corresponding switch input is
closed. When all 4 inputs have
closed switches, all 4 green LED’s
should be on and the RO should be
operating.
NOTE: The inputs on the controller
are configured to operate with
switches that are closed to run. For
the controller to operate, ALL switch
inputs must be closed. IF any of the
inputs are not used, a wire jumper
must be installed across the 2
terminals for that input or the unit
WILL NOT operate.
There are 3 LED>s, DS9-DS11,
located close to the corresponding
relay. When an LED is on, this
indicates the corresponding relay is
activated and the proper voltage
should be output at the terminals on
P1 for the relay. The following table
lists the LED and corresponding
input or output:
LED INPUT / OUTPUT
DS5 Tank Full Low Input
DS6 Tank Full High Input
DS7 Pretreat Input
DS8 Low Pressure Input
DS9 RO Pump Output
DS10 Inlet Solenoid Output
DS11 Flush Solenoid Output
Controller Has No Power:
Verify that the voltage jumpers J3-J6
are in the correct position for the
supplied power. Verify that the
correct power is being applied to the
power in terminals L1 and L2. Check
fuses F1. Check fuse F2 if installed.
If F2 not installed, verify that jumper
is installed at J10. Verify that power
switch is in automatic position.
Controller Shows Low Pressure
When Pressure IS OK:
Turn the power switch to the off
position. After a couple of seconds,
place the switch in the automatic
position. Verify that DS10 lights and
that the inlet solenoid has opened. If
the solenoid does not open, verify
that the proper voltage output is
present on the inlet valve terminals
L1 and L2. If the voltage is present,
check the solenoid wiring and
solenoid valve. If the solenoid does
open, check to see if DS8 is on. If
DS8 is off, check the pressure
switch, the switch wiring and switch
piping.
