Description/Symptoms
A problem has been identified with A.S.U/U.A.S.U’s whereby all the ports lockup on the card on initial programming of the A.S.U circuits if the ONS/OPS circuit descriptor is left at default.
Body/Solutions
Workaround
If using timed break recall change the following values in the ONS/OPS circuit descriptor set the low flash timer to 80 ms and the high flash timer to 350 ms.
If using ground button change the low flash timer to 160 ms and the high flash timer to 160 ms.
Note: If your ports are already in the locked out state you will still need to reload the 3300 controller after these changes have been made.
