4.2.Micrologic P & H for <strong>generator</strong>monitoringThe Micrologic P and H incorporate other current, voltage, power and frequency<strong>protection</strong> and/or monitoring functions suited to loads such as motors, <strong>generator</strong>sand transformers.4.2.1. ImplementationIn the control unit “setting” menu, the operator selectors the functions that hewishes to activate and accesses the various thresholds to be configured.All the settings are made via the keys available on the front face or by remotetransmission.For all functions, except for phase rotation direction, four thresholds must be set:b activation threshold (1)b activation time delay (2)b de-activation threshold (3)b de-activation time delay (4).E88008EActivationthresholdDe-activationthresholdActivationtime delayDe-activationtime delayRelayoutputFigure 25.When the function is activated, according to operator configuration, it can resulteither in tripping or in an alarm, or in both.31
