Operation of the LUTM controllerContinuity of service.DANGERLOSS OF OVERLOAD PROTECTION AND PROTECTION AGAINST OTHERFAULTS MONITORED.If the controller base is connected in "continuity of service" mode, the motor will notstop in the event of a thermal overload or any other type of fault.Failure to follow these instructions will result in death or serious injury..1 23 41 Channel 12 Channel 23 Any fault4 Control unitfaultThere is no longer a fault contact in series with the contactor coils.The motors will not stop in the event of the control unit tripping or an external fault.The controller simply tells the PLC why it is taking the necessary measures:• Branch circuit• Starting up the fansIf used with a multifunction control unit, continuity of service is detected on detectionof a fault current; all the detected alarms are set to zero and are no longer managed.38 1743233 03/2008
Operation of the LUTM controllerFault Management and Reset ModePresence of aFaultThe presence of a fault is indicated by:• The state of the LEDs on the controller base• The state of the LEDs on the communication module (see specific documentation)• The alarm on the multifunction control unit (see specific documentation)• The display of a message on the multifunction control unit screen• The alarm on the advanced control unit used with a function module• The state of the output relays on the controller baseFault ResetFollowing a control unit fault, the acknowledgment method is determined by whichreset mode has been configured and by the type of fault. The operating mode("local" or "remote via the bus") has no effect on the acknowledgment method used.Configuration with advanced control unit:ResetPresence of aCan be reset using the following methods(acknowledgment) communication module LUTM pushbutton Input I.5 Remote via the bus AutomaticManual No YES YES - -Manual YES YES YES No NoRemote YES After delay After delay After delay NoAutomatic YES No No No After delayConfiguration with multifunction control unit (with or without LULC• communication module).Specifically for thermal overload faults:ResetCan be reset using the following methods(acknowledgment) LUTM pushbutton Input I.5 Remote via the bus AutomaticManual YES YES No NoRemote After delay After delay After delay NoAutomatic No No No After delayOther faults (e.g., jam, underload, ground fault):ResetCan be reset using the following methods(acknowledgment) LUTM pushbutton Input I.5 Remote via the bus AutomaticManual YES YES No NoRemote YES YES YES NoAutomatic YES YES YES NoNote: The reset mode ("manual", "remote" or "automatic") must be configuredbeforehand in the multifunction control unit or communication module.
