HOW TO RESET TRIPS ON THE ABORT DUMP BURN THROUGH MONITOR If you have a trip on the abort dump BTM, it usually means that all the air has leaked out of the BTM. To recharge, set access to PEP Zone 8. Inside the tunnel, look for the appropriate abort dump. At the end of the abort dump (under the BLAM) are two small stainless air lines. One is for supply, and one is connected to the switch, which is faulted. Follow the supply line to a valve. Open the valve, you should hear the switch clear. After a few seconds (or you think the BTM is recharged), close the valve. Call MCC to make sure that the status is clear.
