CHAPTER 5: SETTINGS TRANSDUCER INPUTS/OUTPUTSM60 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 5-3335Table 5-44: RTD temperature vs resistanceRTD INPUT H1 APPLICATION — This setting allows each individual RTD to be assigned to a group application. This is useful forapplications that require group measurement for voting. A value of “None” specifies that the RTD operates individually andnot part of any RTD group. All RTDs programmed to “Stator” are used for RTD biasing of the M60 thermal model. Commongroups are provided for rotating machines applications such as ambient, bearing, group 1, or group 2. If the RTD INPUT H1TRIP VOTING setting value is “Group”, then it is allowed to issue a trip if N – 1 RTDs from the same group also pick up, whereN is the number of enabled RTDs from the group.RTD INPUT H1 ALARM TEMPERATURE — Specifies the temperature pickup level for the alarm stage.RTD INPUT H1 ALARM PKP DELAY — Specifies time delay for the alarm stage until the output can be asserted.RTD INPUT H1 TRIP TEMPERATURE — Specifies the temperature pickup level for the trip stage.RTD INPUT H1 TRIP PKP DELAY — Specifies time delay for the trip stage until the output can be asserted.RTD INPUT H1 TRIP RST DELAY — Specifies the reset delay to seal-in the trip signal.Temperature Resistance (in ohms)°C °F 100 ohm Pt(DIN 43760)120 ohm Ni 100 ohm Ni 10 ohm Cu–50 –58 80.31 86.17 71.81 7.10–40 –40 84.27 92.76 77.30 7.49–30 –22 88.22 99.41 82.84 7.88–20 –4 92.16 106.15 88.45 8.26–10 14 96.09 113.00 94.17 8.650 32 100.00 120.00 100.00 9.0410 50 103.90 127.17 105.97 9.4220 68 107.79 134.52 112.10 9.8130 86 111.67 142.06 118.38 10.1940 104 115.54 149.79 124.82 10.5850 122 119.39 157.74 131.45 10.9760 140 123.24 165.90 138.25 11.3570 158 127.07 174.25 145.20 11.7480 176 130.89 182.84 152.37 12.1290 194 134.70 191.64 159.70 12.51100 212 138.50 200.64 167.20 12.90110 230 142.29 209.85 174.87 13.28120 248 146.06 219.29 182.75 13.67130 266 149.82 228.96 190.80 14.06140 284 153.58 238.85 199.04 14.44150 302 157.32 248.95 207.45 14.83160 320 161.04 259.30 216.08 15.22170 338 164.76 269.91 224.92 15.61180 356 168.47 280.77 233.97 16.00190 374 172.46 291.96 243.30 16.39200 392 175.84 303.46 252.88 16.78210 410 179.51 315.31 262.76 17.17220 428 183.17 327.54 272.94 17.56230 446 186.82 340.14 283.45 17.95240 464 190.45 353.14 294.28 18.34250 482 194.08 366.53 305.44 18.73
