7. Measure resistance between pins 2 and 3. Resistance should be less than 100
ohms.
8. Measure resistance between pins 6 and 7. Resistance should be less than 100
ohms.
9. Measure resistance between pins 4 and 5. Resistance should be less than 250
ohms.
If the power module fails for any of the above tests, replace it.
The gold interconnection pins on the power module are protected with a special
contact lubricant. Do not clean or wipe these pins. This contact lubricant is
necessary for proper operation. Inspect each pin prior to assembly of the control
module. If the lubricant is missing, apply a thin film of the recommended contact
lubricant.
The Allen-Bradley approved contact lubricant is NYOGEL 759G, manufactured by
William F. Nye, Inc., Specialty Lubricants, New Bedford, MA 02742 U.S.A.
