TROUBLESHOOTING THE MODEL 1000AR DRIVE
Troubleshooting of the Model 1000AR drive should only be attempted by
personnel experienced in working on high-voltage, high power equipment.
Equipment Necessary for Troubleshooting :
1. Safety Glasses
2. A Volt-Ohm-Milliammeter, preferably digital, with:
• A DC Voltage scale of 1000VDC minimum
• An AC True-RMS Voltage scale of 1000VAC minimum
• A fuse-protected ohmmeter with as low a scale as possible
• A frequency reading capability, if possible
• A plug-in attachment to read AC and DC current, if possible
• Meter leads insulated for 1500 VDC
3. A True RMS clamp on ammeter for AC current, or DC current, or both
4. An oscilloscope is handy if the person using it knows how to use it well.
. 5. Other equipment may be required for some configurations.
6. A Megger is useful for checking motor integrity and wiring insulation.
.
Spare Parts are Necessary to do On-Site Repairs Quickly and Efficiently.
Some or all of the following parts may be required for fast on-site repair.

A Word About The Troubleshooting Charts
Troubleshooting charts cannot solve every problem!
Troubleshooting charts are a useful tool in tracing simple problems down to the board or major component level.
Follow the troubleshooting chart as far as you can until the problem is resolved or you reach a dead end.
If you find yourself coming back to the same point in the troubleshooting chart several times, call the factory and
obtain the help of a trained technician. Let him know what point you keep coming to in the chart. This will help us to
improve the troubleshooting chart in the future.
