4 PKE-SWD-32, interface for motor-starter combination with PKE12/324.9 Programming114 SmartWire-DT modules IP20 09/17 MN05006001Z EN www.eaton.comThe trip in response to a motor overload occurs if the thermal motor image ofthe PKE reaches 110 %. In this case, the PKE-SWD-32 sends the bit value0x5 via the TRIPR data field (input byte 1, bits 4 - 6). This value stays set untilthe thermal motor image goes below the 100% mark and the contactor isonce more operational.The reclosing readiness of the contactor can be selected by the two manualand automatic operating modes of the ZMR function.4.9.2.1 ZMR operating mode manualIn "manual" ZMR operating mode, the retriggering of the contactor must beacknowledged beforehand. The necessity of an acknowledgement is indi-cated by the ACKR bit field (input byte 1, Bit 7). The bit value "1" indicatesthat an overload with manual ZMR function was detected. Bit value "0" indi-cates that no overload is present and that an acknowledgement has alreadytaken place. The "manual" ZMR operating mode is activated by sending thevalue "0" in bit field ZMR M/A (output byte 0, Bit 3).￫ The ZMR function can only be used in position A of the 1-0-Aswitch.￫ In the event of a phase unbalance and activated ZMR function,the value of the thermal motor image is raised from 100 % to110 % after a trip.The switched off contactor's availability to reclose is restoredwhen the value falls below 100 %.
