the same as the one before a (-X2, X3 or X4) is used. Another dash separates the whole unit options listed
after all base system control functions. Example: MGCPF3E-X2-DHY.
Notice: Your unit may not have all features and functions described in this manual. This list represents our
most popular options, additional option codes are available. Consult representative for more details.
Description of Unit
MegaTron controllers may be congured to control one to four separate systems including cooling tower
and boiler applications and may have various features depending on the model number. Whether the unit is
controlling 1 to 4 systems each individual system can be congured with a variety of the functions / features
and there may be feature di󰀨erences between the systems on a unit with multiple systems. (See model
numbering table above).
Control Functions
Each of these control functions are based on an analog input from a probe and will include user settable relay
control settings along with a High and Low Alarm setting and Limit Timer. Each control function will include
a control relay output. When the reading reaches the Set Point the control relay is activated until the reading
changes by the Di󰀨erential amount.

4
1. System Conductivity - The conductivity function of the controller is designed to monitor and control
Total Dissolved Solids (TDS) in a recirculating system like a cooling tower or boiler in terms of
electrical conductivity measured in MicroSiemens/cm. This control function is also referred to as
Bleed.
2. Make-up or Miscellaneous Conductivity -This conductivity with the probe installed in the fresh
make-up water line can be used to control the conductivity of the tower in terms of cycles of
concentration by calculating the di󰀨erence between the make-up water’s conductivity and the
system’s conductivity. It can also be used to monitor another conductivity with no feed timers
associated with it..
3. pH - The pH function monitors and controls pH on a scale of 0-14 pH units.
4. ORP - The ORP function monitors and controls ORP on a scale of +/- 1000 mV.
Chemical Feed Timers
Chemical feed timers are designed to automate the addition of various chemicals by activating a relay output.
Multiple timers can be supplied depending upon the model number and each timer will include a relay output.
All timers can be programmed to be one of the following types.
1. Pulse Time - Accepts pulses from a make-up water meter (supplied separately). It can accumulate
1-9999 gallons before activating the timer to run.
2. Feed with Bleed - Activates the relay output simultaneously with the bleed and limits the amount
of time the relay output will be on during the bleed cycle.
3. Feed after Bleed - Activates the relay output based on a user dened percentage of time based
on the bleed o󰀨, another timer or digital input. The relay is activated after a bleed cycle and runs
for the set percentage of that bleed cycle.
4. Percentage - The relay is on for a percentage of a continuously repeating cycle time that can be
set from 1 minute to 99 hours and 59 minutes.
5. 28 Day - The timer is based on a 28 day cycle with four independent programmable feed cycles
with prebleed and bleed lockout settings.
II. Installation
Electrical Wiring
The MegaTron controller has an internal regulated fused power supply that will operate o󰀨 of 90 to 250 VAC
at 47 to 63 Hz on the incoming wiring. Each output relay is individually protected with a replaceable fuse.
Relay outputs will equal incoming line voltage.
WARNINGS:
1. The controller should be connected to its own isolated circuit breaker, and for best
results, the ground should be a true earth ground, not shared. Wiring must be done
according to all applicable local codes.
2. Power (line voltage) must be disconnected while making any connections. If power is
supplied to the unit, line voltage will be present on the relay cards located in the
lower section of the enclosure, even with the power (ON/OFF) switch o󰀨.
3. Low voltage signal wires (probes, ow switch, water meter, etc.) should never be run
in conduit with high voltage (like 115VAC) wires.
4. Units should be ordered with the appropriate option to provide powered relays designed for the
incoming/outgoing power.
NOTE: Liquidtightttingsandsomelabeledsignalleadsareprovidedforallsignal
(low voltage) connections for both pre-wired and conduit units.

5
Pre-Wired
Pre-wired units are supplied with a 16 AWG cable(s) with 3-wire grounded USA 115 volt plug for incoming
power and 3-wire grounded receptacle cords for all control relay outputs also 16 AWG.
NOTE: An additional male power cord is supplied with each group of 5 relays. All incoming power
cords must be plugged in for the unit to work correctly.
Conduit
Conduit units are predrilled at the factory and supplied with conduit knockouts for easy hard wiring to supplied
detachable connectors on the relay card(s) located in the lower section of the controller. Remove the six
screws of the lower panel for access.
NOTES:
1. Do not drill holes in upper section of enclosure.
2. Relay 1, 6, 11 or 16 (if supplied) only provide a normally open (N.O.) relay output on
relay cards marked Rev B. Revision C of the the relay card has both a (N.O. and
N.C.) If a N.O. and N.C. are required on a Rev. B card, use one of the other relays and
program that relay to be controlled by the desired control function. See page 24.
3. The control function that activates each relay output is pre-congured at the factory
based on the options selected. To change relay activation see on page 24.
4. See page 30 for common bleed / blowdown valve wiring.
5. Refer to label inside lower panel cover for specic relay board conguration supplied.
6. Relays congured as “dry contact” should only have D.C. voltage ran through them.

4-20mA Output Card Wiring
A. IsolatedConguration
For isolated 4-20mA outputs an external power source for the loop must be supplied. JP1 and JP2 on the
board must not be jumpered when an external power source is being supplied. The external power source
must not exceed 24 volts DC and will connect onto the card on connector J1 on the postion marked Loop
Supply.
B. Non-isolatedConguration
For non-isolated 4-20mA outputs the controller will supply the power for the loop. JP1 and JP2 must be
jumpered and no connections are made to the Loop Supply points.
Note: If multiple outputs are being connected to a single energy management system the negatives or commons
MUST remain isolated from each other. Does not apply to Rev. D or later.
4-20mA Input Card Wiring
The 4-20mA input card requires that the external device sending the 4-20mA input signal(s) supply the power
for the loop. The external power source must not exceed 24 volts DC.

Mounting Instructions
Select a mounting location that provides the operator easy access to the unit and a clear view of the
controls through the cover of the controller. The location should be convenient to grounded electrical
connections, the needed sample line plumbing and is on a stable vertical surface.
WARNING: Avoid locations that expose the controller to direct sunlight, vapors, vibration,
liquid spills or extreme temperatures; less than 0°F (-17.8°C) or greater than 120°F (50°C). EMI
(electromagnetic interference) from radio transmissions and electric motors can also cause damage
or interference and should be avoided.
Electrode Installation
MegaTron controllers may come congured for various circulating water systems. Listed below are
instructions for cooling tower and boiler typical installations. Your specic installation requirements may
di󰀨er but should conform to these instructions as much as possible for proper operation.
A. Cooling Tower
The standard probe(s) and/or ow assembly for cooling tower installations is constructed of schedule
80 PVC and supplied with 3/4” slip ttings for installing into a sample line. To insure proper operation
the sample line must have a ow rate of 3-10 gpm. Inlet pressure must be higher than outlet pressure in
order for water to ow past the electrode(s) to achieve the required rate. The probes are temperature
compensated for increased accuracy.
NOTES:
 1. Installanisolationvalveoneithersideoftheowassemblysoelectrodescanbe 
easily isolated for removal and cleaning.
2. A line strainer is recommended upstream from the probes to protect against fouling
and damage.
3. Mount pH or ORP electrodes vertically.
4. Green solution reference wire must be connected to either pH or ORP sensor. If both
pH & ORP are present on system card, only one solution reference connection is
needed.
 5. Systemswithaowswitchrequire2-3gpmowratetooperateoutputs.
WARNINGS:
1. Electrodes are O-ring sealed, which if damaged will cause a leak.
2. Do not allow pH sensor tips to dry out, damage will occur.
3. Do not exceed a water temperature range of 32°F to 140°F.
4. Do not exceed a maximum pressure of 150 psi.

B. Boiler
Standard boiler electrodes have a MNPT stainless steel bushing and are supplied with a FNPT cross
designed for mounting in the skimmer (surface) blowdown line. Sampling of the boiler’s water can be
achieved using one of two typical plumbing congurations (continuous sampling or timed and/or hold
sampling). For a successful installation, it is critical to observe the recommended distances and pipe sizes
provided in the installation drawings. The probes are temperature compensated for increased accuracy.
For best results, the electrode cross should be mounted in a 1”skimmer blowdown line within 4’ of
the boiler. Smaller line sizes and greater distances may a󰀨ect the response time and accuracy of the
electrode. A ow-throttling device down stream from the probe (within 24 inches) is required to ensure that
the electrode is exposed to water and not steam. Properly installed and adjusted, this device will prevent
ashing in the electrode chamber.
NOTES:
1. Install a fully ported type valve between the electrode and the boiler. This
allows the electrode to be isolated for removal and cleaning.

IV. System Operation Overview
Operation
MegaTron controllers have two modes of operation, RUN and SET-UP.
RUN - This mode is for normal operation. In the RUN mode the display will show each system’s parameters.
If an alarm is present the ALARM box will ash how many alarms are present. No settings may be entered or
changed in the RUN mode. Readings are updated every 6 seconds on the screen while in the RUN mode.
SET-UP - This mode is used to make adjustments to settings and readings on the controller. To access the
SET UP mode from the RUN screen, press the SETUP/RUN key.
Typical Start Up Instruction
Complete all installation steps before beginning this procedure. Ensure that all controlled devices (pumps,
solenoid valves, etc.) are operational and connected to the controller. Open the isolation valves to allow water
to pass through the sample stream assembly. Before beginning the start up procedure, familiarize yourself
with the programming and operation of the system by reviewing the menus available. Use the keys of the
controller to skim through all your options.
A. Calibration
All MegaTron controllers are factory calibrated for temperature, conductivity, pH and ORP. All units are
shipped with the date preset, and the clock set to your current time. These readings and settings should be
veried for accuracy, and adjusted as per the instructions listed below.
1. Conductivity - To calibrate the conductivity reading, remove the electrode from the line and wipe the
at surface with a clean cloth. Re-install the electrode and open the isolation valves to allow a sample
across the probe. Be sure to allow the reading to stabilize for one minute. Select “SYSTEM COND” from
the “CALIBRATION” menu. Then key in the corrected conductivity value. Press ENTER to log in that
reading.
2. pH - Under normal operating conditions, pH calibration is achieved using the following steps. From
the “CALIBRATION” menu, select “SYSTEM PH.” Enter the correct pH value. Press ENTER to log in the
new reading.
3. ORP - To calibrate ORP, from the CALIBRATION menu select “SYSTEM ORP”. Compare the displayed
reading to the actual system ORP. If these readings do not match, key in the correct ORP value, and
push ENTER.
There are limits to how much the calibration can be adjusted. The instrument will only accept new conductivity
values which are from 1/3 to 8x the present reading. Any entry outside this range will cause a default to the
original reading. If this happens, call 1-800-743-7431 for technical assistance.

14
V. Menu Navigation
To access the menus press the Set Up / Run key on the front panel. This takes you to the Home menu.
MegaTron controller’s menus are easily navigated by pressing the associated number key next to a menu
box on the screen. Once you have stepped through the sub menus to reach a point at which a value or
selection is made a Pop-up window will appear prompting you to enter a desired value or selection.
NOTE: When entering new numeric values, enter all available digits (characters).
1. Home Menu
From the HOME menu select the desired menu.
The menu name explains what parameters can be
programmed in the menu.
SET POINTS - Setting control set points for conductivity, temperature, pH and ORP.
CALIBRATION - Calibrating conductivity, temperature, pH and ORP if present.
TIMERS - Menu for selecting type and settings for all present feed timers.
CUSTOMIZE - Giving the controller, each system and all relays a user dened name.

WATER METER - Menu for conguring water meter totalizing.
RELAYS - Menu for resetting accumulated “ON” times and manual activation.
2. Set Points
The same basic format is used for dening each available analog probe input’s control parameters. Boiler
conductivity systems will also have an additional menu step for programming the sampling method desired
from continuous, timed or sample and hold.
SET POINTS - For setting the relay set points for the
available analog probe readings such as conductivity,
pH, ORP or temperature.
If there is more than one System present you rst
select which system’s values are to be adjusted. After
the system and function is selected a review page is
provided to show current settings. Select SETTINGS to access each set point menu option.
NOTE: In the Setpoint pop-up screen the direction (Rising or Falling) of the setpoint can also be set. Rising
setpoints will activate the control relay when the particular probe reading rises above the setpoint and will
stay activated until the reading comes down by the amount of the di󰀨erential. If set for Falling the relay is
activated when the probe reading falls below the setpoint and stays on until the probe reading comes back
up by the amount of the di󰀨erential.

2.4 Boiler Conductivity
Conductivity on boiler systems can be congured for Timed Sampling, Sample and Hold or Continuous for
the conductivity sampling method.
Timed sampling incorporates a sample timer which allows the boiler to be sampled at periodic intervals.
Sample intervals are adjustable from 1 minute to 99 hours, 59 min. Sample duration (on-time) is adjustable
from 1 second to 99 minutes, 59 seconds.
Sample and hold uses a sample timer for periodic sampling intervals. The unit will sample for its duration
then hold the blowdown valve closed for a settable period (hold time). The conductivity is checked at the end
of the hold period, if additional blowdown is required the blowdown valve is held open for a preset amount of
time (blowdown time). Then sample cycle is repeated.
Continuous sample has a sample of boiler or condensate water go past the probe continuously. If the
reading is above the set point, blowdown will continue until the set point has been satised.

3. Calibration
Calibration is for adjusting the displayed value of a probes reading to match your tester or known solution.
Pick the system or mA input rst. From a particular system pick the probe to calibrate.
CALIBRATION - For adjusting the actual reading
values of the available analog probe inputs, such as
conductivity, pH, ORP or temperature.
3.1 Conductivity Calibration
CALIBRATE - With a clean probe on-line seeing the
system’s water enter the known (tested from a calibrated
hand held tester) value.
RESET ZERO - With the probe out of solution and dry
enter a new zero point. Note: Probe must be dry!
NOTE: In the calibration pop-up window the raw analog to digital (A/D) value will be displayed. A new
calibration value should only be entered when the probe is sensing a stable A/D value. If the system is a
boiler the associated relay can be forced on in the pop-up to allow for a fresh hot sample. Boiler probes
should have fresh hot water blown past them for a minimum of 2 minutes before calibrating.TheA/Dreading
has a range of 0 to 32,767. If it is at one end of the range or the other when trying to calibrate
something is wrong with the probe or wire run.

3.2 pH and ORP Calibration
1 POINT - With a clean probe on-line seeing the system’s
water enter the known (tested from a calibrated hand
held tester) value.
2 POINT - Enter a known Low value with a clean probe
in a bu󰀨er solution. Then enter a known High value with
the clean probe in a bu󰀨er.
Notes: 1. Probes must be rinsed between bu󰀨ers when doing a 2 Point calibration and given at least
30 seconds in solution to adjust to the bu󰀨er.
2. There must be at least 2 full pH points between bu󰀨er solutions. Using a bu󰀨er of 4 and 10
is the best procedure. ORP bu󰀨ers should be at least 200 points apart.
3.3 4-20mA Output Calibration
4-20mA outputs can be calibrated to insure that the
output generated by the controller and received by the
external device match. With a volt meter connected
across the out and return wires (see page 7) of the
4-20mA output channel to be calibrated go into the
output’s Low or High calibration.
The number displayed in the Calibration dialog box
can range from 0-4095 with 800 equal to 0 mA output
and 4030 equal to 20 mA. This number range of
0-4095 is the raw digital to analog (D/A) values and is
strictly used for a reference. The D / A numbers you
get will vary based on your installation conditions.
While in the High or Low calibration pop-up screen use
the up and down arrows to change the output value
being read with the volt meter. Adjust the High value
for the 20 mA reading and the Low value for the 4 mA
value.

3.4 4-20mA Input Calibration
4-20mA inputs can be calibrated to insure that the input seen by the controller from the external device
match. It also allows for setting the 4-20mA input into a number range that relates to the value being read.
Select the Input to be calibrated
>mA INPUT 1 CALIBRATION<
20mA 3750
4mA 750
MAX 200
LOW 0
OFFSET DISABLED
>mA INPUT 1 20mA CAL<
INPUT 1 CAL HIGH
3750 A/D
PUT 20mA ON INPUT THEN
PRESS ENTER
The 20mA and 4mA values are where the controller’s raw analog to digital value is adjusted to match a
20mA (full scale) and 4mA (bottom of scale) signal from the external device inputting the 4-20mA input. The
external device must be connected to the controller and showing either full scale or bottom of scale when
calibrating each. The number shown along with either the 20mA or 4mA while calibrating is the raw A/D value
and is only a reference. A 20mA input should be around 3750 and 4mA around 750. If the A/D numbers are
not in this range check input device.
The MAX and LOW calibration inputs are for telling the controller what to display for a 20mA input and a 4mA
input. For example if the input is a drum level sensor monitoring a 55 gallon drum the value for MAX should
be 55 and LOW should be 0. The controller then displays a number automatically ranging between 55 and
0 based on the input value. The units of measure (gallons for example) is set in the Customize menu from
the Home page.
OFFSET - O󰀨sets current displayed value of the 4-20mA input reading to allow for a manual 1pt calibration.
4. Timers
A unit may have up to 5 selectable timers for each system on a controller. All timers are associated with their
system, so for a % of post bleed timer looks at the bleed of that system.
TIMERS - Select the type (28-day, pulse, limit, percent
or percent of post blowdown) as well as the run times of
each timer available per system.

4.1 Timer Type Selection
A pop-up screen lets you scroll through the various timer types available.
Pulse - A water meter activated timer
Limit - Feed with bleed with a maximum run time or limit
for one bleed cycle.
Percent -Acontinuous cycle timer that sets a percentage
On time of a cycle.
Percent Post Bleed - For feed after bleed for a settable
percentage of the bleed time with a maximum run time.
28-Day - A biocide or event timer.
4.2 Timer Set Up
Each timer type selected will have its own unique Set Up
sub menu with additional selections specic to the type
of timer selected. The page displayed before entering
the Set Up menu of a timer provides an overall review
of the timers current settings.
4.3 Pulse Timer
ACCUMULATE - The number of gallons or liters from
water meter to count before activating timer.
RUN TIME - The amount of time for the timer to run
METER INPUT - Select water meter 1 or 2 for the
timer’s activation. Water meter 1 + 2 can be selected
only if the meters have the same contact value.
BLEED INTR - Allows the pulse timer to be interrupted
during conductivity bleed. While interrupted, you can
also dene the maximum number of timer run cycles
(1-9) to store for playback.
4.4 Percent Timer
% of CYCLE - The percent of the dened cycle time
that the timer is to be on.
CYCLE TIME - The amount of time in MM:SS that the
cycle is going to be on.
