Rotary

Reed

or

Warning: The ORP and pH Sensors are very fragile and must be handled with care. The tips of the probes must be kept wet at all times, requiring the wetting caps to remain in place until they are ready to be

installed. The probes must be stored in temperatures above freezing.

General Guidelines

Proper installation and use of the BECSys controller depends on the specific needs of the application. Read the manual completely before starting the installation and ensure all guidelines and recommendations are followed. All components should be mounted and the flow cell plumbing installed and pressure tested before wiring the controller. Ensure compliance with all applicable plumbing and electrical codes during the installation as well.

Firmware Version

This manual was written for firmware v1.20. If you received newer firmware but did not receive a copy of the manual covering that version of firmware, please contact your distributor.



Environmental Conditions

The BECSys2 is housed in a NEMA 4X (IP65) enclosure. It should not be used in explosive environments. The BECSys2 should be mounted so that adequate ventilation is provided around the enclosure, preventing general environmental specifications from being exceeded (see table below).

Environmental Specifications Specification Rating Storage Temperature -30 to 60 Deg C Ambient Operating Temperature -18 to 40 Deg C Ambient Humidity 95% non condensing maximum humidity

Electrical Specifications

The BECSys2 may be ordered in either a 115VAC model or a 230VAC model. Following are the electrical specifications for each model:

115VAC Model: Voltage: 115VAC 60Hz Phase: Single Current: 9.25 Amps Full Load (0.25 Amps – Controller) (9 Amps – Relay Outputs, 3A X 3)

230VAC Model: Voltage: 230VAC 50Hz Phase: Single Current: 9.125 Amps Full Load (0.125 Amps – Controller) (9 Amps – Relay Outputs, 3A X 3)



Warnings Warnings

Pay particular attention to the following warnings encountered in the pages of the

BECSys2 Installation and Technical Manual:

Warning: Various other warnings maybe found throughout the manual text.



Section A: Mounting the BECSys2 Controller

A – 1: Mounting the Controller The BECSys2 Controller and flow cell are mounted separately. The BECSys2 enclosure should be mounted to the wall with four anchor bolts, one installed in each corner of the enclosure base. To mount the BECSys2 properly, please use the included mounting template and hardware. Drill the holes for the anchors using a 3/16” drill bit. Install the anchors in the wall. Remove the lid from the unit and place the included screws in the four corners of the box. Attach the screws into the anchors. The BECSys2 and flow cell should be mounted in a location that is free from chemical fumes and excessive heat, isolated from electrical interference, and near a power source protected by a ground fault interrupter. The BECSys2 has a NEMA4 weather resistant enclosure but should still be protected if mounted outdoors.

A – 2: Wrapping the Fittings If you are assembling a flow cell, first open the bag of flow cell fittings and wrap each fitting two times around clockwise with Teflon tape.

A – 3: Assembling the Flow cell Assemble the flow cell as shown below:

When installing the pH or ORP sensor, remove the wetting cap, then remove any existing Teflon tape from the sensor threads. Re-wrap the threads with new Teflon tape. Rinse the sensor tip in de-ionized water and install as shown.

A – 4: ORP and pH Sensor preparations The pH and ORP sensors are shipped with a wetting cap covering the measuring end. This cap contains a solution of pH 4 buffer saturated with potassium chloride (KCl). Gently remove the wetting cap by unscrewing the sensor and sliding the cap off of the sensor body.

It is a good idea to save the wetting cap and the box that the sensor came in for future long-term storage.

During shipping, the air space inside the pH glass may have moved into the bulb. Grasp the sensor near the cable end and gently swing it through an arc to force the internal electrolyte into the pH bulb. Rinse the measuring ends of potentiometric sensors with distilled water before installation into a flow-cell.

A – 5: Plumbing the Sample Stream Install the sample stream; ½-inch tubing is recommended for sample stream pickup and return. Make sure that you tap the supply off the discharge side of the recirculation pump, upstream of the chemical injection points. The sample should be filtered water. Connect the sample stream pickup line to the flow cell and run the sample stream return line from the flow cell to the suction side of the main recirculation pump. Install ½-inch ball valves to allow isolation of the sample lines. Install the pH and ORP sensors last.

NOTE: As soon as you install the sensors, move immediately on to the next step to ensure that they always stays wet.

A – 6: Opening the Sample Stream Valve

Open the sample stream valve and check for leaks. Note the reading on the compound pressure gauge and make sure that it shows a positive and steady pressure. The sample stream should be about 2-20 psi at the flow cell. If this is not the case, then adjust the valves or relocate the point at which the sample stream is connected to the recirculation system. Negative pressure will destroy the sensors. Once you have a positive and steady pressure, open the wet test valve and make sure that it generates a vigorous stream. Warning: These sensors should be hand-

tightened only. Tools are not necessary for installing the pH or ORP sensor and will

damage the sensor housing.



Section B: Wiring the BECSys2 Controller

B – 1: Wiring the Unit

There are several ways that you can wire the relays and power to the unit. The easiest is to use the cords already installed in the unit. Plug the AC Cord into a GFCI outlet (only for low voltage 110VAC-120VAC applications) and connect the chemical feeders to the female power cords (pigtails). The pigtails are labeled with the below warning tags. Be sure to connect the correct pigtail to the correct chemical feeder. You must still remove the cover to install the Flow Switch.

The second way is to discard the pre-installed cords and wire the unit directly.

B – 2: Opening the Cover In order to wire the unit directly or attach the Flow Switch, you must open the cover. Remove the cover by loosening the four screws at the corners with a screwdriver as shown. NOTE: The screws do not need to be totally removed, but only loosened. Once the screws are loosened, carefully lift the top cover off of the unit. The cover will still be connected to the base by the ribbon cable. Set the moisture absorbent packet found inside aside for now.

B – 3: Removing the Safety Shield To remove the shield, remove the four screws using a Philips screwdriver. Gently lift the cover straight up and set it to the side.



B – 4: Disconnecting the Ribbon Cable We recommend that you disconnect the ribbon cable by spreading the two holders at the end of the cable attached to the cover as shown, unplugging the cable and removing the cover.

NOTE: Be sure to store the cover in a safe, dry place while you wire and set up the unit.

B – 5: Wiring Directly to the Unit To wire the unit directly, you must remove the pigtails already installed. You may use the two ½-inch holes in the casing to enable you to easily run wires to Terminal Block 1 inside the base of the unit.

NOTE: There are Terminal Blocks labeled TB1 and TB2 in both the cover and base of the unit and they serve different functions.

Use the ½-inch cord grips provided and whatever holes are convenient, but when you are all finished wiring the unit, be sure to plug any unused holes with a ½-inch NEMA 4x plug.

B – 6: Wiring Power The main power input should be wired to TB1. The black wire goes into the position labeled Line, the white wire goes into the position labeled Neutral, and the green wire goes into the position labeled Earth Ground.

NOTE: The black and white wires are colored brown and blue outside North America.

B – 7: Wiring Relay 1 Directly

Relay 1 controls pH. The black wire goes into the position labeled pH Feed, the white wire goes into the Neutral position next to that, and the green wire goes into Earth Ground position next to that.


Warning: Make sure power is disconnected while you wire the unit

Warning: Unless specified at time of order, controllers are configured for 115VAC and

should not be used at 230VAC. Always contact BECS Technology, Inc. before attempting to

reconfigure a controller’s input supply voltage.



B – 8: Wiring Relay 2 Directly B – 8: Wiring Relay 2 Directly Relay 2 controls ORP. The black wire goes into the position labeled Cl Feed, the white wire goes into the Neutral position next to that, and the green wire goes into the Earth Ground position next to that.

You may select how to power Relay 2: either from the AC Voltage or from the feeder (some Calcium Hypochlorite feeders require that the power for the relay come from the feeder). Placing the jumper next to F3 in the horizontal position (powered) causes the contact to be powered from the AC Voltage. Placing the jumper in the vertical position (dry) allows the relay to be powered from the feeder.


B – 9: Wiring Relay 3 Directly Relay 3 may be used for Dual pH control, Alarms, Cl/Br Booster or the optional Sensor Wash (Refer to C - 1). The black wire goes into the position labeled Auxiliary, the white wire goes into the Neutral position next to that, and the green wire goes into the Earth Ground position next to that.


B – 10: Wiring a Flow Switch

A Flow Switch must be used in the operation of a BECSys2 Controller. A paddlewheel flow switch or reed flow switch is incorporated into the flow cell to disable chemical feed in the event of loss of flow.

Warning: NEVER BYPASS FLOW SWITCH CONNECTIONS

The Flow Switch is a critical safety device which prevents uncontrolled chemical feed.

Uncontrolled feeding of chemicals can result in injury or death.

Warning: Failure to incorporate a Flow Switch and Flowcell into the sample

Stream of your BECSys chemical controller can result in injury or death to swimmers in or

around the pool if the recirculation pump should fail or shut down.



B – 10.1: Paddlewheel Flow Switch B – 11: Wiring a Timer

One advantage of the BECSys2 Controller is that the unit can be used with a timer to control the feeder and still not lose power to the sensor. Most controllers work with a timer by cutting all power, which then means that the sensor goes through an erratic period (up to two minutes) every time power is restored. With BECS units, the sensor continues to function even when the timer cuts power to the feeder so there is never a loss in accuracy. Connect the wires to CN5 in the cover of the unit.

The black wire goes to Ground, the white wire goes to Flow, and the red wire goes to +12V. With the paddlewheel flow switch, whenever the wheel spins, the green “flow” light on the flow switch will be on.

If you have decided to use a timer to interrupt the chemical feed, wire the timer in parallel with the flow lead of the flow switch.

Warning: A check valve is must be installed with the paddlewheel flow switch to prevent backflow when the system is shut down. If a

check valve is not installed, backflow could give the controller a false reading of flow and continue to pump chemicals into the pool.

115VAC Model (F4): ¼ Amp 250V Time Lag Fuse (¼” x 1¼”) The reed flow switch is a (2) two-wire switch. Connect the wires to CN5 in the cover of the unit. The black wire goes to the terminal labeled Flow, and the red wire goes to the terminal labeled + 12.

230VAC Model (F4):

1/8 Amp 250V Time Lag Fuse (¼” x 1¼”) NOTE: Unlike the paddlewheel flow switch, the

reed flow switch is a directional switch. Make sure it is installed with the flow arrow in the proper direction. No check valve is required with the reed flow switch.

Relay Fuses (F1 – F3):

3 Amp 250V Time Lag Fuse (¼” x 1¼”)



Section C: Dip Switch SettingsSection C: Dip Switch Settings

The BECSys2 controller comes preprogrammed for pH feed down (acid, CO2) to feed in Time Based Proportional mode. These factory settings are appropriate for most systems. If you would like to change these settings, you must change the internal dipswitches. To change the dipswitches, first unplug the BECSys2 power cord and open the cover of the unit (as explained in section B - 2). The photograph shows the dipswitch bank (SW5) in the cover of the unit.

The following chart indicates the positions and functions of the switches. Dip Switch OFF ON

1 pH Feed Down pH Feed Up 2 pH TBP Control pH On/Off Control 3 ORP TBP Control ORP On/Off Control4 Failsafe Timer* 5 Failsafe Timer* 6 Relay 3 Function** 7 Relay 3 Function** 8 Unused

*See Section C - 3 ** See Section C - 4 C – 1: Choosing pH Feed Direction

Relay 1 controls pH. It can be set to feed down (acid) for use with chemicals such as carbon dioxide or muriatic acid, or to feed up (base) for use with chemicals such as caustic soda or soda ash. (If you are using Dual pH then Relay#1 is set as Feed Up and Relay#3 is set as Feed Down).

C – 2: Choosing On/Off Control or TBP

In general, if you are using a motor driven chemical feeder then you should choose the On/Off option. If you are using a solenoid driven or pulsed diaphragm chemical feeder (such as Pulsatron, most LMI models or most Prominent Models), you should choose the TBP (Time-Based Proportional) option. This feature helps to hold a set point and to

minimize over-shoot by making a standard feeder mimic the action of more sophisticated modulating feeders. If you choose the On/Off option and are feeding up then the controller will activate the chemical feeder whenever the pH or ORP falls below the set point and continue to feed until the pH or ORP meets or rises above the set point at which point it will stop. If you choose the TBP option the controller will activate the chemical feeder whenever the pH or ORP falls below the set point and will feed for a fraction of one minute depending on the amount of deviation from set point. The balance of each minute the feeder will be paused. The smaller the deviation, the less time the feeder is ON each minute. The feeder will continue this feed and pause cycle until the BECSys2 achieves the set point.

C – 3: Setting the Failsafe Timer Settings The most common failures of automated chemical feed systems are depletion of the chemical supply and/or chemical feeder failure. Both problems result in the controller being unable to reach set point in a reasonable period of time. The Failsafe Timer sets the maximum length of time the feeder can run. If the feeder has been trying to achieve set point without success for the selected time, the controller will cut power to the feeder, flash the feed light on the face panel and display a message to alert the operator. If in TBP Pause mode, the controller will reset. A Failsafe Alarm can be reset by pressing and holding the Up and Down Arrows for 2 seconds. To select the Failsafe Timer interval or disable the Failsafe Timer alarm, move switches 4 and 5 to the positions shown in the following chart. Dip Switch 4 Dip Switch 5 Time (Hours)

Off Off 1 Off On 2 On Off 4 On On Disabled



C – 4: Relay 3 Functions Relay 3 can be used for several different functions. To select the function of Relay 3 move switches 6 and 7 to the positions shown in the following chart: Dip Switch 6 Dip Switch 7 Function Off Off Sensor Wash Off On Dual pH Control On Off Alarm On On Cl/Br Booster

NOTE: You will only have an Alarm Relay when the dip switches are set accordingly. The Alarm LED will still flash when the controller is in Alarm.

C – 4.1: Sensor Wash

Setting Dip Switches 6 and 7 to the off position configures Relay 3 for Sensor Wash. The Sensor Wash will begin 12 hours from power-up, run for approximately 2 minutes, and then come on again every 24 hours after that running for a duration of 2 minutes.

C – 4.2: Dual pH Control Setting Dip Switch 6 to the off position and Dip Switch 7 to the on position configures Relay 3 for pH feed down. You must configure Relay 1 for Feed Up (Dip Switch 1 On).

C – 4.3: Alarm Relay With Dip Switch 6 set to the on position and Dip Switch 7 set to the off position, Relay 3 is configured for an alarm relay. The Alarm Relay will turn on any time there is an alarm state (No Flow, pH High, etc). Alarm points are set in the Programming Section of this manual (Section D).

C – 4.4: Cl/Br Booster Setting Dip Switches 6 and 7 to the on position configures Relay 3 for a sanitizer booster. When the ORP level drops to the Cl/Br Booster trigger set point, Relay 3 will activate an alternate sanitizer feed until the ORP reaches the Cl/Br Booster set point.

C – 5: Replacing the Cover Now it is time to put the cover back on the unit. But before you do, give your wiring one last check and make sure that you reconnect the ribbon cable (as shown) if you disconnected it earlier. Line up the small holes in the cable end with the pins attached to the cover and gently press the cable into place. Make sure the two holders attached to the cover close back over the cable end to hold it firmly in place.

Replace the safety shield using the screws that were removed. Be sure to align the holes with the fuse holders. You may have to adjust the fuse holders slightly to align the shield properly. Finally, place the cover back on the unit and tighten the four screws at the corners to secure it in place.

E – 2.5: Modifying the Booster End Point If relay 3 is configured for Cl/Br Booster control, the screen will display booster end followed by the current end set point. To change this setting, use the Up or Down Arrows to input the new value, then press the Set point key again to save it. To skip entering a new value, press the Set Point key.

NOTE: This menu is only shown if you have the Cl/Br Booster feed is enabled.

E – 3: Single Point Calibration To enter the calibration menu, press and hold the Cal key for three seconds. After the display clears, release the Cal key.

E – 3.1: Single Point Calibration - pH

The display should now read Cal pH followed by the current pH reading. Use the arrow keys to adjust the displayed value to match your test kit reading, and then press the Cal key to save it. To skip entering a new value, press the Cal key.

E – 3.2: Single Point Calibration - ppm If ppm is available on your unit, the display should read Cal ppm and the ppm LED's will be flashing. Use the arrow keys to adjust the LED bar graph to match your test kit reading, and then press the Cal key to save it. To skip entering a new value, press the Cal key.



E – 3.3: Probe Error

If during a single point calibration you receive the error message “Probe Error!” replace the probe.

E – 4: Alarms During normal operation, the following alarms may be displayed. Some alarms will not be available depending on the system's configuration. E – 4.1: pH High/Low alarms

This is displayed when the pH input has risen above/fallen below the pH high/low alarm point. These alarms will also trigger the Cl/Br Lockout alarm.

E – 4.2: ORP High/Low alarms

This is displayed when the ORP input has risen above/fallen below the ORP high/low alarm point.

E – 4.4: No Flow alarm

Displayed when the flow input indicates the flow has stopped. This alarm disables all chemical feeds.

E – 4.5: (x) min Feed Delay

When flow is disrupted and then restored, the controller will delay restarting feeds for a programmed duration in order to prevent operating feeds based on readings from stagnant water. (x) = the number of minutes remaining before feeds are allowed to start (e.g. 5 min Feed Delay).

E – 4.6: Cl/Br Lockout

This is triggered whenever there is a pH high or low alarm. This message indicates that the Cl/Br feed (relay 2) and the optional Cl/Br Booster (relay 3) are disabled in order to prevent the Cl/Br feeds from driving the pH even further out of range.

E – 4.7: pH FAILSAFE ALM

This is displayed when the active pH feed (feed up or feed down) attempted to feed continuously for the selected failsafe duration. The active pH feed is disabled until one of the following conditions occurs: 1) The pH input reaches the programmed set

point. 2) Disruption of flow 3) User manually resets the failsafe.

E – 4.8: Cl/Br FAILSAFE

This is displayed when the Cl/Br feed attempted to feed continuously for the selected failsafe duration. The Cl/Br feed is disabled until one of the following conditions occurs: 1) The ORP/ppm input reaches the

programmed set point. 2) Disruption of flow 3) User manually resets the failsafe.

E – 4.9: Booster FAILSAFE

This is displayed when the optional Cl/Br Booster feed attempted to feed continuously for the selected failsafe duration. The Cl/Br Booster feed is disabled until one of the following conditions occurs: 1) The ORP input reaches the Cl/Br Booster set

point. 2) Disruption of flow 3) User manually resets the failsafe.

E – 5: Resetting a Failsafe Alarm

To reset a failsafe alarm, press and hold the Up and down arrow keys momentarily.



Section F: Maintenance

The BECSys2 requires no maintenance other than a periodic calibration check and sensor cleaning. F – 1: Potentiometric Sensors (pH and ORP)

F – 1.1: Electrode Cleaning: Slow response time and large offsets may indicate the electrode has become coated. The nature of the coating will dictate the type of cleaning technique that should be used.

Soft coatings, like bacterial films, are best removed using a squirt bottle or the water jet from a faucet. If this is not successful, then gently wipe with a soft wet cloth. For a more severe coating, first try a strong detergent (something similar to Dawn liquid detergent) and warm water, using a soft brush (like a toothbrush). Isopropyl alcohol on a Q-tip is another good choice. Rinse the measuring end in distilled water before reinstallation. Greasy and oily coatings are best removed with a detergent solution or a solvent that will not attack the sensor body. Methanol and isopropyl alcohol are good choices for solvents. Acetone, MEK, THF, or trichloroethane will irreparably harm the electrode. Hard coatings, like calcium or lime scale, are best removed with a solvent appropriate for the particular coating. A 5% solution of hydrochloric acid (HCl) would be a good choice for calcium scale. If unsure of the proper solvent to remove a hard mineral coating, then alternate between a 5% hydrochloric acid and a 4% sodium hydroxide (NaOH) for 10 minutes each. After treating the electrode with these strong acids or bases, rinse the electrode with water and soak it in a pH 4 buffer for at least 1/2 hour. The platinum tip of an ORP sensor can be cleaned with an abrasive as a last resort. Gently scour the platinum with a 600 grit wet emery cloth, or preferably, a 1-3 micron alumina polishing powder.

F – 1.2: Long-Term Storage: Save the wetting cap that came with the sensor for long-term storage. After removing the sensor from the flow-cell, clean it as in routine maintenance, and then store it in the wetting cap using a pH 4 buffer saturated with potassium chloride (KCl). The potassium chloride will prevent electrolyte from leaching out of the sensors reference cell. The wetting cap only needs to be half full. If a number of sites are going to be serviced, for example, at the end of a season, then it might be a good idea to carry a pint of 4.0/KCl storage solution.

Warning: You may lightly blot the water On a pH sensor tip on a paper towel, but never vigorously rub or wipe the pH bulb because this may scratch the delicate outer layer on the pH

glass impairing its response.
