You must hook everything up to get it to transmit. There is a power sensor in the PA which sends a signal back to the controller, and if it doesn't see any output power when it knows the exciter is keyed, it tells you that the PA has failed. Since you broke that connection, the PA failure beeps are telling you the truth.
You can use barrel connectors to bypass the two filter sections, but then you won't get the duplex action provided by the filters and the cable. I'd suggest you use a barrel between the exciter and PA input, and connect the PA output to a good 50 ohm dummy load capable of carrying the amount of power you intend to run. Then see if it will key up. If it still only gives you a fraction of a second, try turning the output power down. I think that's a pot on the front of the RF Tray. Sometimes they get turned way up. The station may have a 110w PA, but after you take into account the built-in circulator and the F/D, the rated power is something like 55-60 watts at the antenna jack on the side of the station. You might be able to align the F/D with a station monitor in place of the RF voltmeter or spectrum analyzer. There are several possible ways to configure the equipment to do it. If you know what they want you to do (input signal and output sensor), you should be able to get the right equipment connected.
