Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
"en9l" is not a recognized error on the TC5000, so it is caused by either a faulty console keypad or a communication error in the console.
First, check that all cables are securely attached to the console and nothing has worked its way loose.
If all of the wiring seems fine, then you will require another console.
