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:
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 flowcell.
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
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.
Warning: These sensors should be handtightened only. Tools are not necessary for
installing the pH or ORP sensor and will
damage the sensor housing.
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.

Section B: Wiring the BECSys2 Controller
B – 1: Wiring the Unit
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.
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.
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.
The second way is to discard the pre-installed cords
and wire the unit directly.

Installation and Technical Manual
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.
Rev: D08.1
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: Be sure to store the cover in a safe, dry
place while you wire and set up the unit.
NOTE:
The black and white wires are colored
brown and blue outside North America.
B – 7: Wiring Relay 1 Directly
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.
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.
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.
NOTE:
The black and white wires are colored
brown and blue outside North America.
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
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.
Rev: D08.1
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.
NOTE:
The black and white wires are colored
brown and blue outside North America.
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.
NOTE:
The black and white wires are colored
brown and blue outside North America.
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

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.

Section 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.
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 – 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
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.

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

LMI models or most Prominent Models), you should
choose the TBP (Time-Based Proportional) option.

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.
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).
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.
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.

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 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 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).
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.

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.
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.
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.
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.
