WARNING: Be sure to have a licensed electrician perform all electrical wiring this
is important, as they will be familiar with all the codes in the local area.
2.7 SENSORS
Each sensor has its own unique circuitry that is connected directly to the micro-controller
for direct measurement. The pH and ORP sensors are isolated from each other and from
the input power. The SR6000S measures the following sensor measurements with the
listed characteristics:
1. pH Isolated input, range is 4.22 to 9.78, ±0.02. This measurement is
temperature compensated.
2. ORP Isolated input, range is 0 to 999 mV, ±1mV.

11
STA-RITE INSTALLATION &OPERATION GUIDE
3. Flow Switch (1 input). This input measures if a switch is open or
closed.
4. WARNING: Sensors are shipped with a PVC Cover covering the
electrode tip to protect the sensing element. Sensors should be kept in
the protective cap until ready for installation, if the cotton in the boot
becomes dry, wet it with tap water. During shipment, air bubbles may
have entered the electrode, carefully shake the electrode downward
(like a thermometer) to dispel the air from the sensing elements inside
the electrode. Before using the sensor, remove the boot
2.8 pH AND ORP ELECTRODES
pH electrodes sense the acidity of the water and work with any acid or base. The blue
bands on the cables identify the pH probes. Each probe is also identified on the probe
body.
ORP electrodes are used to monitor the Oxidation-Reduction Potential (sanitization
quality of the water) of a given solution. The sensing element of the ORP electrode is
made of a precious metal such as platinum or gold. The red bands on the cables identify
ORP probes.
2.9 ELECTRODE CARE
Contamination of the sensing elements often results in slow response and inaccurate
readings. Clean the elements by the following procedures:
Wash electrode tip in a liquid detergent and water. Carefully use a soft bristled
toothbrush to wash the electrode tip and white sensing ring.
Rinse after cleaning.
Swirl tip in a 5 parts water 1 part muriatic acid solution for 10 - 20 seconds.
Rinse again and reinstall.
To install, place in flow cell according to the diagram and hand tighten.
Make sure the O-ring is installed on probe.
If the cable is longer than needed, it should be coiled neatly and attached under the
cabinet.
WARNING: DO NOT RUB HARD ON THE ELEMENT OR TRY TO SAND OR POLISH
THE SENSING ELEMENT WITH SAND PAPER OR OTHER POLISHING MATERIAL!
Do not under any circumstances cut or shorten sensor wire.
HANDLE ELECTRODES CAREFULLY. ELECTRODES CONTAIN EXTERNAL AND
INTERNAL GLASS ELEMENTS. DO NOT DROP OR OTHERWISE SUBJECT THE
ELECTRODES TO MECHANICAL SHOCK. ANY TYPE OF BREAKAGE IS NOT
COVERED UNDER WARRANTY. PROBES ARE GUARANTEED FOR 12 MONTHS FROM
PURCHASE. IF A PROBE PROVES TO BE DEFECTIVE, PLEASE RETURN IT TO THE
FACTORY AT ONCE WITH A DESCRIPTION OF THE MALFUNCTION.

STA-RITE INSTALLATION &OPERATION GUIDE
2.10 FINISHING AND TESTING
For the final step, follow the steps below finishing and testing the sensors and feeders.
1. Route the sensor wires through the small strain relieves into the SR6000S and
install them into the appropriate connectors in the control board.
2. Wire the sensors to the SR6000S. The polarity (+ and -) of the pH and ORP sensors
must be observed. The ORP sensor (+) is color-coded red and the pH sensor (+) is
color-coded blue, the green leads are (-) polarity. Do not cut the sensor wires.
3. After the wiring is complete, close the panel and tighten the screws. Leave excess
wire outside of controller box. Do not stuff excess wire inside the controller.
4. Turn the power ON to the SR6000S.
5. Calibrate the probes with the system water at pH and ORP set points, then recalibrate
as the probes acclimate to the pool.
6. Visit the SR6000S over next few days to check the calibration and tune if necessary.
NOTE: try to check the calibrations at the same time of day as when they were
previously performed. Don’t re adjust calibration unless pH is more than +/- 0.5 off or
ORP is more than +/- 5 off.

The ORP feed pump can be exercised in the same manner with the ORP menu button.
3.6 PH AND ORP MENU ITEMS
The pH and ORP menus offer the same choices for setup of feed pump operation. To
access the pH menu simply press the pH MENU button. When the pH menu is active both
the pH FEED LED and pH ALARM LED will be lit, all other LEDs will be off. To access the
ORP menu press the ORP MENU button. When the ORP menu is active both the ORP FEED
LED and ORP ALARM LED will be lit, all other LEDs will be off. Both pH and OPR menus
have the same 5 choices outlined below.
1. Set Point value (StP): Sets the value that you would like the controller to
maintain the pH or ORP levels.
2. Cycle time (CyC): The time that you want a feed pump on/off cycle in
seconds.
3. On Limit (OnL): Sets the maximum time that you want the controller to be
“on” during the cycle time in seconds. This allows you to have a minimum off
time before the beginning of the next cycle.
4. Calibration (CAL): Lets you calibrate the value of the sensor probe to match
a hand check reading.
5. Overfeed time limit (OFL): Allows you to set the maximum amount of time
that the feeder will be allowed to be on during a 24-hour period in hours.
Note: Both the pH and the ORP menus are independent so each will need to be set up
individually.
Also after making changes to the any of the above values you can either return to the
readings display by scrolling through the remaining menu items until you return to the

Note: The Cycle time and On time Limits are tied together; you are not allowed to
make cycle time shorter than the On time Limit and you can not increase the On Time
Limit longer than the Cycle time. Depending on which one that you are increasing or
decreasing the other may increase or decrease with it.
Examples: 1. If “Cycle time” is 600 seconds and you tried to increase “On
time Limit” to 720 seconds the “Cycle time” would automatically increase to
720 seconds.
2. If “On time Limit” was set for 120 seconds and you decreased
the “Cycle time” to 60 seconds; the “On time Limit” would automatically
change to 60 seconds.
3.9 ON TIME LIMIT
Pressing either the pH or ORP Menu buttons three times lets you set the maximum time
that you want the controller to be “on” during the cycle time. This allows you have a
minimum off time before the beginning of the next cycle. For example, if you have a
Cycle Time of 12 seconds and an On Time Limit of 5 seconds the minimum off time would
be 12 – 5 = 7 seconds. Pressing the + button will increase the time value and pressing
the - will decrease the time value that you want to set. (Pressing the + or – buttons
momentarily will increase or decrease the time values one (1) second at a time. Holding

3.11 CALIBRATING PH
Note: A chemical test kit must be purchased separately and utilized for calibration.
Note: IF THE pH IS BELOW 7.4 OR ABOVE 7.6 THE ORP READINGS WILL BE
SIGNIFICANTLY AFFECTED. If the pH is high, the ORP will not go up as fast as it should
when chlorine is added. This can lead to chlorine overfeeding. If the pH is low, the chlorine
will be very active and hard to manage with ORP control.
Measure the pool water pH using a standard hand measurement test kit. To calibrate the pH
sensor press the pH menu button until you see the pH ‘CAL’ibration window (as shown
above). Enter the current hand calibration measurement values by pressing on the + button to
increase the value and press the – button to decrease the value.
3.12 CALIBRATING ORP
WARNING: The pH MUST be at set point, the pH calibration (explained above) MUST be
complete and the pH feed pump should be operating normally and maintaining a constant
pH before calibrating ORP.
To calibrate the ORP sensor: Hand feed Cl into the pool until the PPM level is at the
desired control point. Make sure your ORP set point is set. Measure the pool water PPM
Cl using a standard hand measurement test kit. Wait until the pH feed pump has stopped
feeding and pH is at set point. Now calibrate the ORP sensor by pressing the ORP menu
button until the display has CAL in the left window, calibrate the ORP reading to match
the ORP set point by pressing on the + button to increase the value and press the –
button to decrease the value.
NOTICE: The pH must be between 7.4 and 7.6 when calibrating the ORP sensor. (See
‘Calibrating pH, above). If the pH is outside of these limits when calibrating the ORP
sensor, the chlorine feed and the ORP reading may be incorrect.
