The Fault connector provides a dry contact closure fault signal to notify an external control system when the PAC2 has a system fault. This output is connected to a digital input of the backup computer. A fault is defined as the CPU not interacting with Cresnet® for 10 seconds. The watchdog switches back if the backup computer is inactive for 10 seconds.
