On TKOF passing 12;000 feet Cabin Pressure regulator 1 & 2 faulted. Transferred control of the aircraft. Copilot attempted to regain control of the pressurization manually but was unable. Cabin climbing at same rate as aircraft and we received a cabin pressurization warning. We donned O2 masks; declared an emergency and requested a descent to 10;000 feet with ATC. While turning toward the airfield on a vector from ATC and descending the airspeed momentarily went into the zipper approximately 10 knots. After leveling off at 10;000 feet the First Officer continued to attempt to regain pressurization using the manual controls. We requested vectors to stay in the area while we contacted maintenance and Dispatch. During that time we regained control of the outflow valves manually and upon direction from Dispatch we cancelled the emergency with ATC and requested ATC refile us direct to destination.
On takeoff passing 12;000 feet cabin pressure regulators 1 and 2 faulted and captain took control of aircraft so I could run the QRH. Cabin was climbing at same rate as aircraft. I went on oxygen; declared an emergency; and started to use cabin pressure manual control checklist. When turning back toward airport and descending we momentarily went into the zipper 10 knots. After leveling off at 10;000 feet I was able to control pressurization using manual control and we cancelled emergency. We received extended vectors to communicate with company to see what they wanted us to do. Dispatch wanted us to continue directly to destination; so we coordinated with ATC to fly to destination.
A300 flight crew experiences failure of both automatic pressurization controllers during climbout resulting in a cabin altitude warning. The aircraft is brought back down to 10;000 feet while the pressurization system is examined. The First Officer is able to gain control of the outflow valve manually and the flight continues to destination.
