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.
Caution: The BECSys controller should be sealed while under operation. All IO, power cables, and unused
ports must be sealed using hardware rated NEMA4 or better. Damage to the controller caused by improper
Caution: The BECSys controller should not be installed where it is accessible to the public.
sealing of the enclosure is not covered under warranty.
Firmware Version
This manual was written for firmware v1.54. 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 BECSys5 is housed in a NEMA 4X (IP65) enclosure. It should not be used in explosive environments. The
BECSys5 should be mounted so that adequate ventilation is provided around the enclosure, preventing general
environmental specifications from being exceeded (see table below).

Operation and Maintenance Manual
Section A: Programming the Controller
Rev: L13
A – 1: Adjusting the Display Contrast
You can adjust the display contrast by holding down
either the up or down arrow keys for two seconds,
then after the controller beeps three times, use the
up and down keys to adjust the contrast.
A – 2: Security Settings
A – 2.1: Access Codes and levels
To view what access level you were given, press
the lock screen button while in any menu.
The Main Menu will also display who is logged on
along with the version of firmware.
You do not need to set all the access codes for
each level if you do not wish to. Also, a disabled
access code is not equivalent to 000, so entering
000 when it prompts for an access code will only
work if you have specifically assigned an access
code to be 000.
A – 2.2: Setting Access Codes
To set an access code, press the menu button,
then:
Select System Config
Choose User Setup
Then select the access level you want to set an
access code for.
To set Operator 1's access code, you would select
Oper. Access Codes, then select Operator 1.
Pressing and holding the +/- button disables the
access code, while pressing enter will enable and
set the access code to the value on the screen.
Operators may only change their own access code.
Managers may change their access code and any of
the Operators.
A – 2.3: Controller Options
Depending on how a particular controller is
configured, not all of the options listed in this
manual may be available.
A – 3: Navigating the menus
The controller's menus incorporate built in help text
to aid in understanding the function of each
parameter, item, and option.
A – 3.1: Common status messages
The very bottom line of the display contains the
time and date on the left while the right is reserved
for a number of status messages; the most
common are as follows:
"Busy..." - Indicates the controller is busy doing
something critical and it cannot stop until it
finishes. Until this message disappears, the
controller will not respond to your key presses
(although it does record them any will process
them when done). Normally this message is only
seen briefly after changing a setting, but it is also
used for lengthier operations such as factory
defaults and in the extremely rare case where the
internal diagnostics detect a memory problem and
attempts to correct it.
Warning: Interrupting the controller by
turning the power off while it displays the busy
message could result in the complete loss of all
"(1 of 2) (More )" - and the like indicate there
are more options for you to choose from than the
controller could show at one time. Press the right
arrow key (Next) to view them. The left number
indicates the current page, while the right number
indicates the total number of pages.
"Bad Value, Retry..." - Accompanied by an error
beep, this indicates the value you just entered was
not within the allowable range of values and was
not stored.
of its settings.

Operation and Maintenance Manual
A – 3.2: The Menu Screens
Most of the features of the controller are
configured via the Menu button's menus. The
menu screens can be broken up into two types:
entry screens and lists.
A – 3.2.1: Entry Screens
An entry screen is used to enter a value using
the keypad.
Rev: L13
A – 3.2.2: List Screens
The list screens are mainly composed of lists of
menu items that you can choose from by either
pressing an item's number or by using the up
and down arrow keys to select it (indicated by
the arrow) and then pressing enter to choose it.
Using the up and down arrow keys also allows
you to view each item's help text. And if the
item leads to an entry screen or a list screen that
sets a setting (see below), the current value is
displayed in the lower right side.
Lists can also be used to change a setting:
The current value is usually displayed at the top
while the cursor will be positioned under the
current digit or character of the value you are
entering in. The up and down arrows allow you
to move the cursor right or left so you do not
have to retype the existing digits if you only wish
to change one.
Most numerical values will display the minimum
and maximum values you can enter in at the
bottom of the display in the format "< ### to
###>". These ranges many times will be
dependant on other values you have set, such as
alarm points or set points, while others are
simply fixed to stay within a reasonable range.
Entering a value that is not within the acceptable
range will result in an error beep and the
message "Bad Value, Retry..." being displayed in
the status area.
For some values, certain keys may take on
special functions that are explained in the lower
lines of the screen. The Down/up message in
the example above is one of them.
When a list is used this way, it will display the
current setting followed by the words "Change
to:". Because it is a list, you can select an item
with the up/down buttons to see help
information about that particular selection.
There are a few list screens that use the entire
width of the display for displaying values
associated with each item and therefore do
not have help. See Section C: Using the
Quick Set Face Panel Keys for examples of
these types of screens.

Operation and Maintenance Manual
A – 3.3: The Lock Screen Key
When not in a menu (i.e. viewing the normal
display), pressing the lock screen key will prevent
the controller from paging the screen to show
more inputs, alarms, and other status information.
See Section B: The Normal Display for more info
about using the lock screen key in the normal
display.
While within any menu, if the user does not press
a key within sixty seconds of the last key press, the
current user is logged out and the screen is
returned to the normal display. To prevent the
controller from timing out, you may lock the
screen.
While within a menu, pressing the Lock Screen key
will bring up a popup menu:
The first option on the popup will be either to
lock or unlock the screen depending on the
current lock state. While the screen is locked, key
presses normally are ignored. However, in some
instances certain keys are given special functions
while the screen is locked, such as using the up
and down arrows to scroll the help text if all of the
help text cannot be displayed at once.
You can also lock/unlock the screen without
bringing up the popup menu by holding down
the lock button for one second. The
controller will acknowledge this action with a
triple beep and the yellow Lock Screen light
will turn on.
The Lock button popup menu also identifies who
is currently logged on, and provides an option for
the user to log off. You can also select cancel if
you pressed the lock button in error.
Rev: L13
A – 4: Inputs
To enter the program menu, press the Menu button
on the front face panel of your controller. This will
allow the viewing of the Main Menu where the
programming options are displayed.
The Cl inputs, Cl Inventory Input, Chlorine
Control, and Chlorine booster control are all
displayed as either Chlorine and Cl or Bromine
and Br depending on the chemical selected in the
Cl feed menu. This manual is written using the
Chlorine setting. If you select Bromine as the
sanitizing chemical, the controller will display
Bromine and Br instead of Chlorine and Cl, but
the menus and functions are otherwise exactly the
same as shown.
