33 Megatron Interface By the end of this session, you should be able to: Navigate the MegaTron menu structureProgram the core functions of a MegaTron
34 Megatron Interface SETUP/RUN - toggles between setup and run modes HOME - takes you to the home setup page from any sub-menuENTER - saves changes made to dialog box entriesCANCEL - aborts changes made to dialog box entriesBACK - takes you to previous menu; erases last entry in dialog boxesHELP - provides help tips from any setup menu; fast forwards through alpha-numeric text entriesARROWS - up & down scroll through dialog box choices; left & right move cursor in dialog boxes or change the operation of selective functions (i.e., rising/falling setpoint)NUMBERS - access menus ATM-style; enter numeric values for all programming
35 Menu StructureThe Megatron home setup page is divided into 10 major submenus:SETPOINTSCALIBRATIONTIMERSCUSTOMIZEALARMSDATE/TIMECONFIGUREHISTORYWATER METERRELAYS
36 Setpoints MenuThe SETPOINTS menu allows you to change setpoints and alarms levels for all analog inputs (probe & 4-20 mA).Setpoint = relay “on” pointrising: conductivity, acid feedfalling: ORP, caustic feed, closed loop treatmentDifferential = required movement away from the setpoint before deactivating the relay (aka: deadband or hysteresis)High & low alarms do not interrupt relays.Limit time only interrupts pH or ORP relays.
37 Setpoints Menu - Sampling Modes MegaTron controllers can utilize 3 different sampling methods. Method #1:Continuous - Used when the probe will see a continuous water sample at all times (cooling towers or very large boilers). Controller will continuously monitor the water and control accordingly.
38 Setpoints Menu - Sampling Modes Method #2:Timed - Used only when intermittent sampling is desired (small to medium sized boilers). Controller will control the boiler water conductivity only after an active sample cycle (duration) and then remain inactive during the off-period (interval). Time initiates the control cycle, but the conductivity reading ends it.
39 Setpoints Menu - Sampling Modes Method #3:Sample & Hold - Similar to timed sampling with the addition of a “hold” period to allow steam to settle in a line before reading the water sample. Controller will alternate between “hold” and “blowdown” periods until conductivity setpoint is satisfied.
40 Calibration MenuThe CALIBRATION menu allows you to make calibration adjustments to all analog inputs (probe or 4-20 mA):One point = check hand tester and correct the MegaTron’s readingTwo point = calibrate against two different standards (or zero the probe for conductivity)Not necessary to calibrate ORP (it is what it is)
41 Timers MenuThe TIMERS menu allows you to select the timer type and activation settings for all taggable timers.Pulse (water meter must also be programmed)Percent (good for low dosage, repeated feed throughout the day - some biocides)With-bleedPost-bleed28-day (can be interlocked with ORP to feed to an ORP setpoint only at certain times of the week)
42 Customize MenuThe CUSTOMIZE menu allows you to customize the on-screen names of:Megatron unitSystemsRelaysNotepad (name, measurement units, alarm levels)pH index (LSI or RSI)4-20 mA inputs (name, measurement units)
43 Alarms Menu Date/Time Menu The ALARMS menu provides a complete listing of all current alarms for each individual control system.Date/Time MenuThe DATE/TIME menu allows you to set the controller’s current date, time, day of week, and week number.
44 Configure Menu The CONFIGURE menu allows you to change: Passwords Admin = full access (except “factory” settings)User = access restricted to defined areasRelay assignmentchange which function controls which relayHistory resolution & alarm delayDisplay contrastNetwork settings (covered in more detail later)Factory-level settings (several submenus deep)
45 History Menu The HISTORY menu allows you to view: Sensor history - conductivity, pH, ORP, temp.Relay logs - time stamp for each on/off activationAlarm logs - time stamp for each alarm conditionEvent logs - time stamp for keyboard activityNotepad history - all user-entered test dataWater meter - makeup, bleed-off, evaporation
46 Totalizers Menu Relays Menu The TOTALIZERS menu allows you to adjust the contact value of water meters and feed verification devices (must be programmed to utilize water meter actuated feed or chemical volume feed calcuations)Relays MenuThe RELAYS menu allows you to view:Relay name and functional assignmentRelay status (forced on, forced off, or auto)Totalized relay on-time and date of last reset
47 Programming Test #1Setup a System #1 as a cooling tower controller to perform the following:Maintain conductivity between 1300 and 1400uS.Maintain pH between 7.5 and 7.8 and prevent acid overfeed by using a 45 minute feed limit timer.Feed an oxidizing biocide to maintain an ORP residual of between 300 and 350mV (falling setpoint).Use Timer 1 to feed inhibitor for 45 seconds for every 100 gallons of makeup water that enters the system (water meter #1).Use Timer 2 to feed a non-oxidizing biocide every Monday, Wednesday, and Friday at 7:00 a.m (pre-bleed & lockout are optional).
48 Programming Test #2Program these additional settings into your cooling tower system:Setup the extra timer to feed closed loop treatment using water meter #2 (2 minutes per 50 gallons).Setup a user password that will prevent access to the calibration, setpoints, and timers menus.
49 Programming Test #3Setup System #2 to act as a boiler controller to perform the following:Sample the boiler water every 3 hours for 1 minute and maintain conductivity between 3800 and 4000uS.Setup a timer to add a boiler treatment for 2 minutes per 50 gallons of fresh makeup water introduced into the feedwater tank.How many total relays will this 2-system controller utilize?
50 Megatron Hardware By the end of this session, you should be able to: Locate and identify the basic component parts of a MegaTron controllerUnderstand the field-upgrade processUtilize the factory password to unlock extra features
51 Hardware OverviewThe MegaTron controller is divided into two main compartments:Logic (top) - contains motherboard, system cards, communication card, low voltage wiringPower (bottom) - contains power supply, relay cards, fuses, high voltage wiringThese two compartments are physically separated by a panel divider.
52 System CardsSystem cards contain connections for probes, water meters, flow switches, and drum level inputs (22AWG wiring).The card features a yellow status LED near the bottom.The card plugs into a slot on the motherboard.
53 Motherboard Slot #1 is always communications. Slot #2 is always System 1.Other slot assignments will vary depending on configuration.Incoming power connector is in the bottom left corner.Relay card connections are in the bottom right corner.Firmware can be updated by inserting a program card.
54 Relay Cards Relay cards contain 5 relays each. Relays 2-5 can be NO/NC Relay 1 is NO only, but can be set as a dry contact in the field by clipping a jumper.Each relay is individually fused with a 2.5A fuse.Each relay card has it’s own power input (bottom left connector) and logic input (top right ribbon cable).
55 Field UpgradesWith optional expansion buses, Megatrons can be upgraded with:Additional system cardsCommunications cards4-20 mA cardsExtra control relays can be assigned as needed
56 Adding New Cards Adding a new card to a MegaTron requires two steps: Physically install the card and wiring connectionsActivate the card and new functions through the “Factory” menuFactory password is required (daily use only - resets to a new factory password on the following day)
57 Unlocking New Features New programming features can be unlocked in the “factory” submenu using the factory password.New cards, inputs/outputs, relays, timers, water meters, flow switches, level wands, etc. can all be enabled through software.New features require the appropriate hardware (enabling pH through software does no good if the pH circuit isn’t available).
58 Hardware Test Your MegaTron should have an unused relay. Use this extra relay and unlock a new timer to feed a steam line treatment into your boiler system.Program the new timer as you wish.Consult the “cheat sheet” if necessary.Bonus points - What is the complete model number of your upgraded MegaTron controller?
