Operation and Maintenance Manual Rev: C17
Section A: Programming the Controller
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.
"(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.
Warning: Interrupting the controller by
turning the power off while it displays the busy
message could result in the complete loss of all
of its settings.

Operation and Maintenance Manual Rev: C17
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.
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.
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:
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 Rev: C17
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.
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.

A – 5: Control Outputs
Press the Menu button on the front of the Controller
and select Control Outputs. Depending on the
controller configuration, some control outputs may
or may not be installed.
A – 5.1: pH Control
If your controller is configured to control pH, you
will have the following options:
Control Type (Op): Choose from On/Off or
Time Base Proportional control.
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 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 falls
below the set point and continue to feed until
the pH rises above the set point plus
hysteresis at which point it will stop.
If you choose the TBP option and are feeding
up then the controller will activate the
chemical feeder whenever the pH falls below
the set point and will feed for a percentage of
the Time Base (default one minute)
proportional to the offset from set point. For
the remainder of the Time Base the feeder will
be paused. The feeder will continue this feed
and pause cycle until the controller achieves
the set point plus hysteresis. The closer to set
point, the less time the feeder is ON.
Set Point (Op): This value sets the desired level
to maintain the pH at. Input the desired pH set
point.
Span/Prop. Bnd (Op): This option is only shown if
the Control Type is Time Base Proportional. This value
sets the distance (or span) from the set point that
the output will be proportionally controlled.
Time Base (Op): This option is only shown if the
Control Type is Time Base Proportional. This sets the
total time that control is based on. During this
time, the feeder will turn on for a percentage of
the Time Base and turn off for the remainder.
Failsafe Timer (Op): This value sets the time
that the relay is allowed to stay continuously on.
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 Reset Fail/Safe LED on the face
panel and display a message to alert the
operator. If in TBP Pause mode, the
controller will reset the timer.
An operator must reset the failsafe through
the Reset Fail/Safe button to re-enable
normal control.
Dead Band (Mgr): This option is only shown under
dual pH control.This value sets the amount the
input must exceed the set point by before the feed
of the opposite direction will trigger. (The range is
from twice the feeds' hysteresis to 2.8 pH)
Warning: Disabling the failsafe timers is
highly discouraged. They are an important
safety feature to protect against dangerous
chemical overfeeds and will protect the
equipment from running continuously if it runs
out of chemical.
Warning: Increasing or decreasing the
Span/Prop. band or Time Base may cause the feed
to severely overshoot or never achieve set point.
Adjust this option only when recommended to do
so by a factory representative.

A – 5.2: Chlorine Control
If your controller is configured to control
Chlorine, you will have the following options:
Sanitizer Chemical (Op): Sets the sanitizer
chemical name (Chlorine or Bromine).
This option controls what chemical name the
controller displays for the ppm Input and the
primary sanitization/oxidizing chemical.
Control Input Src (Op): This option is only
available if the controller is configured for ppm. Choose
between ORP and ppm to use as the primary
control input for the sanitizer feed.
If the ppm Input is selected and the ppm
Input source is set to probe, chlorine control
is disabled while the ppm interlock timer is
running.
If the ppm Input is selected and the ppm
Input source is set to calculated, the controller
still controls off of ORP, but the ORP set
point is calculated by the controller based on
the ppm set point, the pH set point, and the
ppm calibration. Modification of any one of
those three values will result in a new ORP set
point.
Control Type (Op): Choose from On/Off or
Time Base Proportional control.
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 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, then the
controller will activate the chemical feeder
whenever the ORP falls below the set point
and continue to feed until the ORP rises
above the set point plus hysteresis at which
point it will stop.
If you choose the TBP option, then the
controller will activate the chemical feeder
whenever the ORP falls below the set point
and will feed for a percentage of the Time
Base (default one minute) proportional to the
offset from set point. For the remainder of
the Time Base the feeder will be paused. The
feeder will continue this feed and pause cycle
until the controller achieves the set point plus
hysteresis. The closer to set point, the less
time the feeder is ON.
ORP Set Point (Op): This option is NOT available
if using calculated ppm control.This value sets the
desired level to maintain the ORP at.
ORP Span/Prop. Bnd (Op): This option is only
shown if the Control Type is Time Base Proportional and
the ORP Set Point is shown above. This value sets the
distance (or span) from the set point that the
output will be proportionally controlled.
Free Cl Set Point (Op):This option is only shown if
the Control Source is set to ppm.This value sets the
desired level to maintain the ppm at.
Free Cl Span/Prop Bnd (Op) This option is only
shown if the Control Type is Time Base Proportional, the
Control Source is set to ppm, and a ppm probe is installed.
This value sets the distance (or span) from the set
point that the output will be proportionally
controlled.
Time Base (Op): This option is only shown if the
Control Type is Time Base Proportional. This sets the
total time that control is based on. During this
time, the feeder will turn on for a percentage of
the Time Base and turn off for the remainder.
Failsafe Timer (Op): This value sets the time
that the relay is allowed to stay continuously on.
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

panel and display a message to alert the
operator. If in TBP Pause mode, the
controller will reset the timer.
Warning: Increasing or decreasing the
proportional band may cause the feed to
severely overshoot or never achieve set point.
Adjust this option only when recommended to
do so by a factory representative.
Warning: Increasing or decreasing the time
base may cause the feed to severely overshoot
or never achieve set point. Adjust this option
only when recommended to do so by a factory
representative.
