Product Description

The Azure® Digi-Motor® from MARS is a high efficiency variable speed direct drive blower motor for a multitude of
applications. Azureis a replacement for both standard PSC and Genteq X-13 motors. Two motors
®
cover ratings from 1/5 HP to 1 HP at 115V or 230V and CW or CCW.

Azure® features an auto sizing learn mode. In start-up learn mode, Azure® runs for approximately 2 minutes
measuring the external static pressure of the system application. Azure® then assigns torque values to each of its

speed taps self-programming itself to the correct horsepower for the application.

If none of the four speeds provides perfect airflow for the application or if duplicate speeds are desired on 2 or more
taps, an optional hand held programmer (MARS No. 08502) can be used. The programmer connects to Azure® and

displays the percentage of torque applied to the speed tap being energized. The percentage (motor speed) can then
be increased or decreased and permanently set with the programmer. This tool overrides the motor torques

established in the auto sizing mode.

Unlike other electronically commutated motors, an outboard surge protector is included within Azure’sM wire harness.
This is a replaceable device (MARS No. 08593).
