IV. System Operation Overview

Operation

MegaTronMT controllers have two modes of operation, RUN and SET-UP.

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 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

Note: Boiler probes must have a fresh hot sample. See page 16 for more details.

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 1-918-686-6211 for technical assistance.
