Repairs

CAUTION: Abuse of Module After Failure
If an internal fault has occurred and the Module will not reset, do not tap, strike, or otherwise attempt to
correct the fault by a physical impact to the housing.
An internal relay may have failed in such a man-
ner that its replacement is required.
If the Module is not immediately replaced or repaired, multiple simultaneous failures may accumu-
late such that the safety function can not be guaranteed.

Do not attempt any repairs to the Module. It contains no field-replaceable components. Return it to the factory for warranty
repair or replacement, as follows.
Contact Banner Factory Application Engineering at the address listed on

. They will attempt to troubleshoot

the system from your description of the problem. If they conclude that a component is defective, they will issue a return merchandise
authorization (RMA) number for your paperwork, and give you the proper shipping address.
Pack the Module carefully. Damage that occurs in return shipping is not covered by warranty.
