ALT-284 Dual-Station Production Testing
The ALT-284 is designed to provide a high accuracy test of alternators in a very short period of time.
With dual stations, the operator can be loading the next alternator into one station while the second station is testing another unit. With optional automatic connections the cycle time can be as fast as 11 seconds. The alternator is driven via a changeable socket, hex or torx driver. The user friendly environment makes the setup and test procedure as simple as pressing a button.
This machine not only tests the product to a preset limit, but has a diagnostic system built in. If the unit does not pass the test the operator is given a detailed explanation as to why the unit did not work. This eliminates the guess work by the operator.
The ALT-284 uses a PC based system with a variable speed drive 15 or 20 HP motor, battery simulator and programmable electronic load. During the automatic test the computer controls the alternator speed and load according to programmable test procedure to verify the alternator and voltage regulator. For a precise voltage regulator check, the car’s on board computer and connection problems are also simulated. Cut-in (turn on) speed, soft start delay, LCR (Load Control Response) function, feedback signal to the on board computer, tachometer output frequency, the rectifier’s voltage drop and reverse diode leakage, the voltage regulator saturation voltage, stator voltage and many other parameters are also measured. Tests new generation units with PCM, RVC or Lin Interface.
When the test is complete, the computer verifies all parameters and prints reports. If a fault is identified, diagnostic messages are displayed. Test results are recorded for SPC and analysis. The ALT-284 is supplied with a built in label printer port (24 pin), built in RS232C serial interface for data exchange or SPC programming, and test plugs for the most popular applications. The ALT-284 is available in many working voltages (208 to 480V at 50/60 Hz).
