    The following protection circuits are integral to the GA45xxPR2 plifier to prevent damage to the amplifier or your equipment. Again, Glentek is anxious to work with you in helping to implement any circuit functions your system might require. Note: For sections 2.3.1 to 2.3.7, refer to Appendix B, drawing 4581-4010.

    The Current Sense output signal can be monitored at TB201-7 of the Control card. It is an isolated out- put signal that is proportional to motor current. The scale factor is 1 volt = 15 amps on the GA4571PR2, GA4576PR2, and GA4581PR2, and 1 volt = 25A for the GA4582PR2.

    After reviewing the fault tracing charts you may conclude that the complete amplifier should be re- turned to Glentek for failure analysis, repair and retesting to specifications. This is particularly true with fail - ure modes in the amplifier power section.

    Note: The fault latch will not reset unless the fault has been removed. 7.3 FACTORY REPAIR: Should it become necessary to return a GA45xxPR2 to Glentek for repair, please follow the procedure de scribed below: 1. Reassemble the unit, if necessary, making certain that all the hardware is in place.

    3. Repackage the unit with the same care and fashion in which it was received. Label the container with the appropriate stickers (e.g. FRAGILE: HANDLE WITH CARE). 4. Contact a Glentek representative, confirm the unit is being returned to the factory and obtain an RMA (Return Material Authorization) number.
