Control and monitoringDescriptionSepam performs the basic control and monitoring functions necessary for theoperation of the electrical network, thereby reducing the need for auxiliary relays.The control and monitoring functions may be parameterized using the SFT2841software tool, however each type of Sepam has parameter setting by default whichallows easier commissioning in the most frequent applications.ANSI 94/69 - Circuit breaker/contactor controlSepam is used to control breaking devices equipped with different types of closingand tripping coils:b circuit breakers with shunt trip or undervoltage trip unitsb latching contactors with shunt trip units.The breaking device control function processes all the circuit breaker closing andtripping conditions based on:b breaking device status informationb remote control ordersb protection functionsb program logic specific to each application (e.g. recloser).This function also inhibits breaking device closing according to the operatingconditions.With Sepam series 20, it is necessary to use an MES114 module in order to have allthe required logic inputs.Switching of groups of settingsUsed to switch from one group of phase overcurrent and earth fault protectionsettings to another group of settings. Switching may be performed by a logic input orvia the communication link.Inhibition of thermal protectionThermal protection tripping may be inhibited via a logic input.Re-accelerationAllows a logic input to take into account the restarting of an unstopped motor.ANSI 68 - Logic discrimination (SSL)This function allows quick, selective tripping of the definite time or IDMT phaseovercurrent and earth fault protection relays, without requiring the use of timeintervals between upstream and downstream protection devices. The downstreamrelay transmits a blocking input signal if the protection device set points areexceeded.The upstream relay receives the blocking input signal on the logic input used for theinhibition function. A saving mechanism ensures the operation of the protection in theevent of an inhibition link failure.ANSI 86 - Latching / acknowledgmentOutput relay latching may be parameterized. Latched tripping orders are stored andmust be acknowledged in order for the device to be put back into service. The useracknowledges via the keypad or remotely via a logic input or the communication link.Latching is stored in the event of a power outage.Trip circuit supervisionDetects trip circuit faults (shunt trip units). Detects open/closed position discrepancyfaults (undervoltage trip units).WatchdogIndicates Sepam unavailability via output O4.Output relay testThis function is used to activate each output relay.24
