Abstract
A fault monitoring system detects connectivity faults in a device control centre. The fault monitoring system includes, for the or each control section, at least a first pair of temperature sensors adapted to detect the temperature of a first pair of terminals (TL1-IN), (TL1-OUT). The system includes a processor configured to receive the detected temperatures, calculate an IN-OUT difference, the IN-OUT difference being a difference between the temperatures of the first pair of terminals (ΔTL1), compare the calculated IN-OUT difference with a predetermined threshold value (ΔT*L1), whereby a calculated difference IN-OUT (ΔTL1), greater than the predetermined threshold value (ΔT*L1), is indicative of a connectivity fault at one of the first pair of terminals, and to generate at least one output signal based on the results of the comparison.
