  • Page 3: Introduction

    Model Numbering table listed below. Model Numbering MegaTronMT units have several base system control functions and unit optional features. Your unit may be supplied with one or more of the features described in this manual. To determine what features apply to your unit check the model number label located on the controller enclosure.

  • Page 4: Installation

    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. Pulse Time - Accepts pulses from a make-up water meter (supplied separately).

  • Page 5: Wiring Diagrams

    NOTES: 1. Liquid tight fittings and some labeled signal leads are provided for all signal (low voltage) connections for both pre-wired and conduit units. 2. Units should be ordered with the appropriate option to provide powered relays designed for the incoming/outgoing power.

  • Page 8: Mounting Instructions

    Electrode Installation MegaTronMT controllers may come configured for various circulating water systems. Listed below are instructions for typical cooling tower and boiler installations. Your specific installation requirements may differ, but should conform to these instructions as much as possible for proper operation.

    III. Front Panel Description SET UP/RUN - System initializes into RUN mode. Press this key to put the controller in SET UP Mode and see HOME menu page. HOME - Used to go back to the HOME menu page. HELP - Used to access help screens.

  • Page 13: System Operation Overview

    Calibration All MegaTronMT 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 verified for accuracy, and adjusted as per the instructions listed below.

  • Page 14: Menu Navigation

    To access the menus, press the Set Up / Run key on the front panel. This takes you to the Home menu. MegaTronMT 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.
  • Page 15 Set Point Options SET POINT - What reading turns the relay on. DIFFERENTIAL - Amount reading changes by before the relay is turned off HIGH ALARM - What reading generates a High alarm. LOW ALARM - What reading generates a Low alarm. LIMIT TIME - What amount of continuous bleeding will generate a time alarm notice.
  • Page 16 SET POINT - What reading turns the relay on DIFFERENTIAL - Amount reading changes by before the relay is turned off HIGH ALARM - What reading generates a High alarm notification. LOW ALARM - What reading generates a Low alarm notification.
  • Page 17 2.6. 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 first. 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.
  • Page 18 2.7. 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, recycle, percent of post bleed, or other event), as well as the run times of each timer available per system.
  • Page 19 2.7.d. Recycle Timer ON CYCLE - The amount of the defined time that the timer is to be on. OFF CYCLE - The amount of time that the cycle will be off. ON/OFF TIMER - This is the displayed countdown of time for the cycle the timer is in.
  • Page 20 2.7.g. 28-Day Timer Each 28-Day timer has Program 1-4 for programming the various feed times. While the programming steps for four programs are the same, each can have its own independent settings. WEEKS - The week(s) that the timer is to feed. DAYS - The day(s) that the timer is to feed.
  • Page 21 2.9. Water Meters / Totalizers Each system with a timer on it will have 2 water meter inputs. Each of these can have the incoming contact defined, allowing the controller to keep track of water usage. If desired, the controller can calculate evaporation loss by subtracting the deference between a system’s two water meter inputs.
  • Page 22 3.1. 4-20mA Out Settings Units with a 4-20mA output option will have a menu for setting up the 4-20mA output. The 4mA and 20mA values can be defined by giving the output proportioning capability. i.e. 4mA = a pH of 6.0 and 20mA = a pH of 8.0.
  • Page 23 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 voltmeter. Adjust the High value for the 20-mA reading and the Low value for the 4-mA value.

  • Page 25 SENSOR 1 - The first sensor reading or Notepad value to be used in the calculation. SENSOR 2 - The second sensor reading or Notepad value to be used in the calculation. mA Inputs NAME - Name the input. UNITS - Set the units of measurement. NUMBER - Set the number range.
  • Page 26 Password ADMIN PASSWORD - The administrator password gives access to all menus except factory set up. USER PASSWORD - The user password allows the user to access HOME menus that are made available in USER SET UP. Date and Time Set Up DATE AND TIME - For setting the date, time, day, and week on the controller.
  • Page 27 History This menu is used to set the history “time stamp” interval, the water meter daily history starting hour, the alarm delay period and the USB history save format. INTERVAL - The amount of time between each history time stamp for probe readings. W/M HOUR - The time of day that the daily water meter history cycle is to start.
  • Page 28 History The onboard history allows for viewing the history of the probe readings, relay activations, key-pad activity, calibrations, water meter hourly and daily logs, and alarms for each system present. It is also where Notepad data is entered and reviewed. An initial overview page is displayed showing your current sample interval, the calculated number of days the unit can keep probe history for before losing the oldest.
  • Page 29 A unit may have up to 10 option auxiliary flow meter inputs. These additional inputs are for tracking various flow meter devices like Advantage Controls’ FloTracker in a metering pump’s discharge tubing. They can also be linked to a system’s water meter input for additional tracking and alarm capabilities.
  • Page 30 Relays STATUS - Allows for viewing accumulated relay ON times, temporary forcing relays ON or OFF or seeing which relay is on. RESET - Allows the accumulated run time of a particular relay to be reset to zero. FORCE - Allows a relay to be manually forced ON or OFF for a single event from 0-999 minutes.

  • Page 31: Maintenance

    VI. Maintenance The only required maintenance for normal uninterrupted operation of your MegaTron MT controller is cleaning of the electrode(s). After initial startup, it is a good idea to clean the electrode frequently until a schedule based on need has been developed. Since each application is unique, it is difficult to estimate the required frequency of cleaning.
