A – 1: Mounting the Controller The BECSys3 Controller and flow cell are mounted separately. The BECSys3 enclosure should be mounted to the wall with four anchor bolts, one installed in each corner of the enclosure base. To mount the BECSys3 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 BECSys3 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 BECSys3 has a NEMA4 weather resistant enclosure but should still be protected if mounted outdoors.

A – 2: Wrapping the Fittings When assembling the 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 (if included) sensors, remove the wetting cap, and 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: 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.

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.




A – 5: Free Chlorine Sensor

The BECSys3 can be ordered to accept two different Free Chlorine Sensors: the CCS140 or the ECL6. A – 5.1: CCS140

The CCS140 Free Chlorine Sensor can be connected to the BECSys3 using the appropriate option board. The CCS140 Free Chlorine Sensor is mounted in a flow cell which includes a flow and psi restrictor assembly as shown below:

The CCS140 Free Chlorine Sensor requires a constant flow rate and a constant pressure. This helps ensure that the ppm level will remain stable.

Here is the recommended method for plumbing the free chlorine sensor flow cell:

Admission pressure must be above the regulated pressure (15 psi is the limit on the sensor). Run

the sample stream through a flow restrictor valve (to maintain flow rate, minimum flow rate requirement is 8 gph). Take the stream through the flow cell. Discharge the sample stream to a free outlet (for example into a surge tank). The CCS140 Free Chlorine Sensor is supplied with a yellow protective cap. This cap has an inner sponge that is used to keep the sensor membrane hydrated. This cap should be saved for long-term storage. The sensor can remain in the flow cell for short-term interruptions in measurement. To prevent membrane dehydration, the flow cell must not drain off. If this is not ensured, then remove the sensor from the flow cell and slide the yellow protective cap, moistened at the inner sponge, onto the measuring end of the sensor. The voltage applied by the controller to the CCS140 Free Chlorine Sensor polarizes the surface of the gold cathode. The polarization period (30 minutes) must elapse before calibration is performed based on the results acquired through the use of a DPD test kit. See Section H - 2.3 for filling the electrolyte.

A – 5.2: ECL6 The ECL6 Free Chlorine Sensor can be connected to the BECSys3 using the appropriate option board.

Caution: Amperometric chlorine sensors require the use of a temperature sensor and a properly calibrated pH sensor. Refer to the instruction pamphlet included with the

sensor at the time of installation.

Warning: Negative pressure will damage the sensor membrane.




A – 6: Sensor Preparations NOTE: As soon as you install the sensors, immediately move on to the next step to insure that they always stay wet. A – 6.1: Sensors

The pH and ORP (if included) 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 de-ionized or distilled water before installation into a flow cell.

A – 7: 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.

A – 8: Plugging in the Sensors Remove the protective covers from the BNCs. Plug the pH sensor into the coded BNC jack and the ORP (if included) sensor into the coded BNC jack on the bottom of the BECSys3 controller by twisting them a quarter of a turn. Allow the sensors to rinse in the sample water while you do the wiring (Section B).




SSeeccttiioonn BB:: WWiirriinngg tthhee BBEECCSSyyss33 CCoonnttrroolllleerr

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, and any other optional components.

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 (and any optional components), 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 ½-inch holes in the casing to enable you to easily run wires to Terminal Block 1 (TB1) 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: Supplying Power To The Relays

All three of the relays may be configured to be powered from either the L (Line) connection which the controller itself is powered from, or their individual C (Common) connections. As shipped from the factory, all three relays are configured to be powered from the L (Line) power connection. If you wish to use the C (Common) input instead (commonly used to interlock feeds with the recirculation pump), you will need to move the black hat jumpers located above TB2 to their upper position for the desired relays.

NOTE: The relays inside the controller are solid-state and can only switch AC signals. If you need to switch DC power, an external Mechanical Relay must be used.

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 1 Relay 1 controls pH. You can configure the relay to be powered from the same Line voltage as the controller or from its own separate voltage input.

B – 8.1: Line Powered

Make sure the hat jumper is in the lower position “L”. 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. Nothing should be connected to the pH COM terminal.


B – 8.2: Common Powered

Connect the incoming power to the pH COM terminal (the red wire shown below) and move the hat jumper for the pH relay to the upper position “C”. The black wire goes into the position labeled pH Feed. Leave the Neutral and Earth Ground terminals unconnected inside the controller. The Neutral and Earth Grounds from the feeder must be connected to the Neutral and Earth Ground of the power source supplying this relay.

B – 9: Wiring Relay 2 Relay 2 controls ORP. You can configure the relay to be powered from the same Line voltage as the controller or from its own separate voltage input.

B – 9.1: Line Powered Make sure the hat jumper is in the lower position “L”. The black wire goes into the position labeled Cl/Br 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. Nothing should be connected to the Cl/Br COM terminal.


B – 9.2 Common Powered

Connect the incoming power to the Cl/Br COM terminal (the red wire shown below) and move the hat jumper for the Cl/Br relay to the upper position “C”. The black wire goes into the position labeled Cl/Br Feed. Leave the Neutral and Earth Ground terminals unconnected inside the controller. The Neutral and Earth Grounds from the feeder must be connected to the Neutral and Earth Ground of the power source supplying this relay.




B – 10: Wiring Relay 3 Relay 3 may be used for Dual pH control, Alarm, Cl/Br Booster, or Sensor Wash (Refer to Section C on how to configure this). You can configure the relay to be powered from the same Line voltage as the controller or from its own separate voltage input. B – 10.1: Line Powered

Make sure the hat jumper is in the lower position “L”. 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 Earth Ground position next to that. Nothing should be connected to the AUX COM terminal.


B – 10.2: Common Powered

Connect the incoming power to the AUX COM terminal (the red wire shown below) and move the hat jumper for the Aux relay to the upper position “C”. The black wire goes into the position labeled Auxiliary. Leave the Neutral and Earth Ground terminals unconnected inside the controller. The Neutral and Earth Grounds from the feeder/device must be connected to the Neutral and Earth Ground of the power source supplying this relay.

B – 11: Wiring a Flow Switch A Flow Switch must be used in the operation of a BECSys3 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. B – 11.1: Paddlewheel Flow Switch

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.

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.

Warning: A check valve 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.



Installation and Technical Manual Rev: H10 B – 11.2: Reed Flow Switch

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.

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.

B – 12: Wiring a Timer

One advantage of the BECSys3 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. 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.

Timer

Flow Switch

B – 13: Wiring the Temperature Sensor

The optional temperature sensor is wired to CN5 in the cover of the unit. The white wire goes to the terminal labeled "+", and the black wire goes to the terminal labeled "-".

B – 14: Wiring a Free Chlorine Sensor B – 14.1: CCS140

The CCS140 Free Chlorine Sensor is wired to the option board inside the controller. If you ordered your controller with the option board, it is located on the lower left side of the lid. There is a three position pluggable terminal block where the wires will be connected. Connect the red "A" wire to the A terminal, the "K" white tip with transparent wire to the K terminal, and the thick unlabeled wire to the ground terminal.

B – 14.2: ECL6 The ECL6 Free Chlorine Sensor is wired to the option board inside the controller. If you ordered your controller with the option board, it is located on the lower left side of the lid. There is a two position pluggable terminal block where the wires will be connected. The red wire goes to the position labeled “red” and the black wire goes to the position labeled “black”.




B – 15: RS485 Network B – 15.1: BECSys RCM

If you have ordered a BECSys RCM, or the site has a BECSys RCM already installed, you may connect your BECSys3 to it. The BECSys RCM provides data logging and remote access of up to 32 BECSys3 controllers per site. Recommended wire: 22 gauge shielded twisted pair (1 pair: 2 conductors + shield). For outdoor use, use NEC type PLTC. For indoor use, use NEC type CMG general, CMR riser (through floors), or CMP plenum as required by the local wiring code. Connect the wires to CN4 in the cover of the unit. There are two RS485 terminal blocks to allow daisy chaining of units. It doesn’t matter which connector you use – whichever is easiest. For each unit, wire as follows:

From BECSys3 To BECSys RCM A A B B SH Shield

Refer to the BECSys RCM manual (included with your BECSys RCM) for more information on how to configure the network.

SSeeccttiioonn CC:: DDiipp SSwwiittcchh SSeettttiinnggssThe BECSys3 controller comes preprogrammed for pH feed down (acid or CO2), Time Based Proportional feed mode, Probe Wash, and temperature shown in °F. 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 BECSys3 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 Control 4 NOT USED 5 NOT USED 6 Relay 3 Function* 7 Relay 3 Function* 8 Temperature °C Temperature °F

* See Section C – 3 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 rises above the set point plus hysteresis 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 the Time Base depending on the amount of deviation from set point. The balance of the Time Base, the feeder will be paused. The smaller the deviation, the less time the feeder is ON. The feeder will continue this feed and pause cycle until the BECSys3 achieves the set point plus hysteresis.

C – 3: 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 Probe Wash Off On Alarm On Off Dual pH 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 – 3.1: Probe Wash

Setting Dip Switches 6 and 7 to the off position configures Relay 3 for Probe Wash. The Probe 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 2 minutes.

C – 3.2: Alarm Relay Setting Dip Switch 6 to the off position and Dip Switch 7 to the on position configures Relay 3 for Alarm. 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 – 3.3: Dual pH Control Setting Dip Switch 6 to the on position and Dip Switch 7 to the off position configures Relay 3 for dual pH control (pH feed down).

C – 3.4: 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 point, Relay 3 will activate an alternate sanitizer feed until the ORP reaches the Cl/Br Booster End point.

C – 4: Temperature With Dip Switch 8 On, temperature is displayed in Fahrenheit. With the Dip Switch Off, temperature is displayed in Celsius.

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). 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.

F – 1: Calibration Error If during calibration of the inputs you receive the message “Calibration Error” check the following: 1) Try calibrating again, allowing more time

between the 1st and 2nd point calibration. 2) If you are using a BECSys HRC-1 make sure the

Hi-Z switch is in the off position. 3) Double check to make sure you have the proper

wires connected to the input.

F – 2: Probe Error The BECSys3 has some limits in place to help detect a bad probe. As probes are used, the electrolyte is depleted and the readings become farther off. The “Probe Error” message indicates the probe has been calibrated too far away from these safety limits. When you see a “Probe Error” it is time to change the probe.

SSeeccttiioonn GG:: UUppggrraaddiinngg FFiirrmmwwaarree

The BECSys3 Firmware can be upgraded in the field. To do so you order the upgrade Firmware, this comes on an 8 pin dip IC and then complete the following steps:

1) Remove power from the unit. 2) Install the 8 pin dip IC into the socket labeled “Firmware Upgrade” at the top of the BECSys3 CPU board. Make

sure pin 1 is aligned properly. 3) Reapply power. 4) The unit will display the current Firmware Version followed by “Found Firmware“ and the Firmware Version on

the upgrade IC. 5) Next the BECSys3 will display “Do Not Interrupt” followed by “Upgrading Firmware” and the percentage

complete. 6) Once the Firmware upgrade is complete, the unit will display “Do Not Interrupt” followed by “Restoring Cal

Data” and the percentage complete. This restores the calibration data. 7) Finally, the BECSys3 will display “Do Not Interrupt” followed by “Upgrade Complete”. Once the upgrade has

finished, the unit will reset and start up normally.

Once the upgrade is complete, remove power from the BECSys3 and remove the Firmware Upgrade IC from the controller. At this point, you may discard the Firmware Upgrade IC.




SSeeccttiioonn HH:: MMaaiinntteennaannccee The BECSys3 requires no maintenance other than a periodic calibration check and sensor cleaning. H – 1: Potentiometric Sensors (pH and ORP)

H – 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.

H – 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.

H – 2: CCS140 Free Chlorine Sensor Check the sensor measurement at regular intervals (at least once a month), and perform a recalibration if necessary. As a rule of thumb, refill the measuring cell with electrolyte once per season (or every 12 months). H – 2.1: Cleaning If the sensor membrane is visibly soiled, then

remove the sensor from the flow cell and clean the membrane with a gentle water jet, or soak the membrane for a few minutes in a 1% to 10% hydrochloric acid (HCl) solution. Avoid chemical additives as they may damage the membrane.

Replace a heavily soiled or damaged membrane. H – 2.2: Long-Term Storage

Save the yellow protective cap that came with the sensor for long-term storage. After removing the sensor from the flow cell, empty the measuring cell of electrolyte (particularly if dehydration of the membrane is possible). Rinse the measuring chamber and electrode shaft with cold water and let them dry. Then screw the measuring cell down loosely and not to the stop, so that the membrane remains unstressed. When the sensor is put back into service, it will have to be refilled with electrolyte and run through an initial polarization before calibration.

H – 2.3: Filling electrolyte Unscrew the measuring chamber from the shaft. Hold the measuring chamber at an angle and fill
