TECHNICAL DATA SHEET wo N 6 AMPCONTROL INTEGRATED PROTECTION RELAY IPM Version 2 Applications The IPM Integrated Protection Relay provides all the necessary protection functions to control the various types of mining machinery The default Status Screen allows unskilled personnel to determine what is required to apply power to the machine See IPM User Manual 121549 for full details Alarms Alarms can be programmed to warn of a pending trip condition Earth Leakage The earth leakage protection function uses a 1000 1 core balance toroid to measure the earth fault current A Residual 4 Current Device RCD operating characteristic is provided with adjustable trip sensitivity and time delay When the earth leakage reaches 100 of the selected trip level a trip occurs START eser STOP The higher the fault current measured the faster the trip time and vice versa See IPM User manual 121549 for full details Earth Continuity The earth continuity function tests for the continuity of the earthing between the outlet and the machine via the pilot core in the trailing cable The pilot core is also used to transfer data when a Remote Termination Module is used to achieve Machine Data Transfer Short Circuit The short circuit function has a definite time characteristic If the current exceeds the selected level for the pre set time then a trip occurs The short circuit function trips the CBR relay which in turn can
