Run/Shut-off Time Setting
(continued)
If you want the pump to run continuously as long as the rinse signal is
active, turn the potentiometer completely counterclockwise.
To limit the duration that the pump runs turn the potentiometer clockwise
to adjust from 1 to 240 seconds (as shown to the right).
When adjusting the right potentiometer, turn slowly clockwise while
watching the LED to help set the correct run/shut-off time. The pump
displays four setting positions by flashing the LED:
When set between 60 and 90 seconds the LED will flash red once.
When set between 90 and 120 seconds the LED will flash red twice.
When set between 120 and 180 seconds the LED will flash red 3 times.
When set between 180 and 240 seconds the LED will flash red 4 times.
The LED of a model R1ST can display three colors to indicate the various pump operation phases:
LED Color
Fixed or Flashing
Indication
Green
Fixed
The only time the LED should display as fixed green would be if the pump has reached the
Run / Shut off time and stopped, but the signal remained active.
Flashing
Flashing green indicates the pump is dosing the, and the frequency of the flashing is
proportional to the user-defined pump speed.
Orange
Fixed
Fixed orange means the pump is in Priming Mode.
Flashing
You should not see the LED flashing orange, unless you are in Custom Programming Mode
(If you do See the LED flashing orange, please contact Technical Support at Hydro Systems
Co.)
Red
Fixed
Fixed red indicates the signal is active, but the pump switch is to the standby/OFF position.
(See OFF Alarm in the Flashing text below.)
Flashing
Flashing red quickly (1 second on, 1 second off) is an alarm that the pump motor is jammed,
or if a level probe is in use, that the chemical supply is low.
Flashing red more slowly (2 seconds on, 2 seconds off) is the OFF Alarm, indicating that the
signal has been active for over 600 seconds, while the pump switch is in the standby/OFF
position.
Additionally, as described above, the LED will flash red is when setting the right potentiometer
for shut off time.
