Section B: Normal Operation

B – 1: Displaying the Set points

To display the Set Points, press the Set point key
briefly. The set points will be displayed for three
seconds.

B – 2: Modifying the Set Points

To modify the set points press the Set Point key for
three seconds. The display will change to pH SetPt
followed by the current pH Set Point.

B – 2.1: Modifying the pH 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.

B – 2.2: Modifying the ORP Set Point

If the system is configured to control using an
ORP set point, the screen will display ORP SetPt
followed by the current ORP 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.

B – 2.3: Modifying the ppm Set Point

If the system is configured to control using a ppm
set point, the screen will display ppm SetPt and the
current ppm set point on the LED bar graph will
be flashing. To change this setting, use the UP or
Down Arrows to adjust this value shown on the
LED bar graph and press the Set point key again
to save the new value. To skip entering a new
value, press the Set Point key.

B – 2.4: Modifying the Booster Trigger Point

If relay 3 is configured for Cl/Br Booster control,
the screen will display boostr trig followed by the

current trigger 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.

B – 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.

To enter the calibration menu, press and hold the Cal
key for three seconds. After the display clears,
release the Cal key.

B – 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.

B – 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.

Operator's Manual Rev: D08

B – 3.3: Probe Error

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

B – 4: Alarms

During normal operation, the following alarms may
be displayed. Some alarms will not be available
depending on the system's configuration.

B – 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.

B – 4.2: ORP High/Low alarms

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

B – 4.4: No Flow alarm

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

B – 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).

B – 4.6: Cl/Br Lockout

B – 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.

B – 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.

B – 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.

B – 5: Resetting a Failsafe Alarm

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

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.

Section C: Maintenance Section C: Maintenance

The BECSys2 requires no maintenance other than a
periodic calibration check and sensor cleaning.

C – 1: Potentiometric Sensors (pH and ORP)

C – 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

 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.

lass impairing its response.

C – 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.
