|Logically ORs four inputs, all inverted, from <b>Alarm 1</b>, <b>Alarm 2</b>, <b>DigAlarm 2</b> and the signal break output (<b>SBrkOut<b>) from <b>IO.PV</b>. The output is active unless any of the alarms are triggered or signal break is active. Essentially inhibits operation of Stage 1 and Stage 2 in the event of a fault condition. | |Logically ORs four inputs, all inverted, from <b>Alarm 1</b>, <b>Alarm 2</b>, <b>DigAlarm 2</b> and the signal break output (<b>SBrkOut<b>) from <b>IO.PV</b>.
