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 flash how many alarms are
present. No settings may be entered or changed in the RUN mode.
☼
NOTE: 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.
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 verified for accuracy, and adjusted as per the
instructions listed below.
An accurate temperature reading is critical to a good conductivity reading as the
temperature compensation factor is approximately 1% per degree F.
1. Conductivity - To calibrate the conductivity reading, remove the electrode from
the line and wipe the flat surface with a clean cloth.
open the isolation valves to allow a sample across the probe. Be sure to allow the
reading to stabilize for one minute.
"CALIBRATION" menu.
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
Select "SYSTEM COND" from the
