Connect mains power to the Control Module (CM), the rear panel chassis safety ground to a known good
ground, and press PWR. A momentary message, indicating software version number and other
information, appears briefly on the CM display. LEDs are turned on briefly, and then the default displays
will appear as shown below:

DISPLAY MESSAGES
These values correspond to a balanced three-phase voltage of 120V phase-to-phase, and current which will
be in phase with the voltage. If an output module isn’t fitted with a full complement of output sources,
there will be less data on the display(s). If the current output module, for example, has only two current
sources, only lines IA and IB will appear on the display.
The example that follows illustrates some of the important operating aspects of the system. It’s assumed
that a single phase impedance relay with a time delay response is connected to the MTS-3000 system,
operating at approximately 50 volts and seven amps, with a phase shift between voltage and current of 75°.
