Operation
The controller has a two position
power switch to control the
operating mode of the controller.
When the switch is in the left
position, the controller is off and all
outputs will be turned off. If the
switch is moved to the right position,
the controller is in the automatic
mode. In this mode, the controller
operation is automatic and is
controlled by the input signals.
Auto Mode:
When the switch is placed in the
auto position, the inlet solenoid will
operate and the controller will
monitor the low-pressure switch. The
RO pump will start after the RO start
delay if no shutdown condition is
present.
Low Pressure:
If a low-pressure condition occurs
and the low-pressure switch input
opens for the low-pressure delay
time, the controller will shut down for
a low-pressure fault. The red Low
Pressure lamp will light. If the auto-
reset jumper is in the off position, the
controller will remain in low pressure
shut down until reset. Placing the
power switch in the off position for
several seconds and then returning
it to the auto position reset the
controller
Auto Reset:
If the auto reset jumper is in the on
position when a low pressure shut
down occurs, the unit will attempt to
restart after the auto reset delay,
(this should be approximately 15
minutes). If the low-pressure
condition has cleared, the unit will
continue to run. Otherwise, the unit
will again shut down and the auto
restart will continue as long as the
low-pressure condition is active.
Pretreat:
If the pretreat lockout switch opens
for the pretreat delay time, the unit
will shut down for a pretreat
condition. The amber Pretreat lamp
will light. The unit will remain shut
down until the pretreat switch
closes. The unit will then restart.
Tank Full:
The controller is designed to operate
with either 1 or 2 tank level switches.
When a tank full condition occurs,
the unit will shut down and the
amber Tank Full lamp will light.
When the tank full condition clears,
the unit will restart after the tank full
restart delay.
If the unit is operated with only 1
level switch, the Tank Full Low input
must remain jumpered. In this mode,
when the tank full high switch opens
for the tank full delay time the unit
