When used with redundant power supplies, the affected module may not detect and report the loss of a single supply. If the redundant supply is subsequently lost, the control system will lose all power and shut down without system notification. Internal to the potentially affected modules are blocking diodes that prevent power from one power supply affecting the detection circuitry for the other power supply. When a single supply becomes non-operational, the detection circuitry signals the system of the loss resulting in an LED indication on the module’s faceplate and the generation of a fault alarm. The system will continue to operate on the remaining supply. On a small percentage of modules, the blocking diodes may allow power from the remaining operational power supply to affect the detection circuitry for the non-operational power supply. This will prevent detection circuitry for the non-operational supply from signaling a loss supply condition to the system.
