A gas-fuelled boiler is used to provide heat in a manufacturing plant. The power to the boiler is switched manually. A detection system is incorporated to detect if the flame is on. At start up or if the flame goes out an ignition system is switched until the flame appears or 5 seconds have elapsed. If the flame does not appear after 5 seconds the gas is turned off and a warning light is switched on. List the inputs and outputs of the system. Q 2(c) [9 Marks] Draw a response diagram of the system described in Q2b to show the relationship between the inputs and outputs of the system.
