Description
Product details:
The 0-57170 is a regulator module manufactured by Reliance Electric in the FlexPak Plus series. Each controller in the system supports a 0-57170 regulator module. The 0-57170 model is 14C650.
Digital drive modules work as device drivers in larger drive controllers. This part runs the software that operates the drive controller and acts as a converter between the hardware device and the operating system that uses it.
When properly installed, the digital driver module should have an ignition pulse and should output to the power cube of the drive controller. The regulator module should output to the digital driver module. The primary side of the pulse transformer has a resistor, and the pulse waveform should be +11.2v. The readings on the power cubes 47 and 45 should be 0-240 for 230 VAC controllers and 0-500 for 460 VAC controllers.
If you need to troubleshoot, first test the output of the regulator module to the digital driver module. If all is well, test the trigger pulse of the digital drive. To be safe, be sure to turn off the power, then turn on the main switch and loosen the regulator/digital drive module assembly (four screws at each corner). Next, connect the oscilloscope to pin 57 on the regulator module. Connect the oscilloscope probe to the resistor or digital drive plate on the primary side of the pulse transformer at 7A. Turn the power back on and switch to the boot position. Change the SPEED POT to the full on position. If the ignition pulse does not appear and readings cannot be obtained at 14A, 10A, 11A, 13A, and 8A, replace the digital drive module.
