If it fulfil the requirements then dismantle, separately delivery after packaging. 15 MAN32-12SY03 附件1 Annex 1 Name Messstelle Beschreibung Motor Bedingung Grenzwert Hysterese Delay 名称 测量点 说明 机型 条件 设定值 滞后 延时 Engine Speed Switching Points 柴油机负荷开关设定点 overspeed alarm超速报警 757Hz / 1SAH1000 2SE1000 LV32/40CD 750 rpm -30 rpm - 825 rpm via pulse counter通过脉冲计数器 overspeed shutdown超速停车 791 Hz / 1SZH1000 2SE1000 LV32/40CD 750 rpm - - 863 rpm via pulse counterr通过脉冲计数器 TC Speed Switching Points增压器转速设定点 97% of max. tc-speed,H(?100% load) 增压器最高转速 97%(?100%负荷) alarm报警 1SAH1004 1ST1004A/B LV32/40CD -2% 4s tc speed high增压器转速高 100% of max. tc-speed,H(,100% load) 增压器最高转速100% (,100%负荷) 100% of max. load reduction request降负荷要求 tc-speed,H 1SZH1004 1ST1004A/B LV32/40CD -2% 4s tc speed high增压器转速高 增压器最高转速100% Main Bearings主轴承 alarm报警 1TAH1064 xTE1064 V32/40CD 103?C,H -2K 4s main bearing temp high 主轴承温度高 auto shutdown自动停车 2TZH1064 xTE1064 V32/40CD 108?C,H -2K 4s main bearing temp high 主轴承温度高 Lube Oil Engine柴油机滑油 external luboil alarm报警 1PAL2170 1PT2170 LV32/40CD 2.8 bar,L 0.1 bar 4s pump lube oil pressure low滑油压力低 机外滑油泵 external luboil auto shutdown自动停车 2PZL2170 2PT2170 LV32/40CD 2.5 bar,L 0.1 bar 4s pump lube oil pressure low滑油压力低 机外滑油泵 alarm报警 1TAH2170 1TE2170 LV32/40CD 70?C,H -2K 2s lube oil temp high滑油温度高 lauto shutdown 自动停车 2TZH2170 2TE2170 LV32/40CD 73?C,H -2K 2s lube oil temp high 滑油温度高 Lube Oil TC增压器滑油 alarm报警 1PAL2570 1PT2570 LV32/40CD 1.1 bar,L 0.1 bar 4s turbocharger lube oil pressure low 增压器滑油压力低 auto shutdown自动停车 2PZL2570 2PT2570 LV32/40CD 0.9 bar,L 0.1 bar 4s tc lube oil pressure low 增压器滑油压力低 alarm报警 5K above 110%-value 1TAH2580 1TE2580A/B LV32/40CD at testrun, H -2K 2s tc lube oil temp high 高于试车110%数值5K 增压器滑油温度高 10K above auto shutdown自动停车 110%-value at testrun, 2TZH2580 2TE2580A/B LV32/40CD -2K 2s tc lube oil temp high H高于试车110%数值增压器滑油温度高 10K 16 MAN32-12SY03 Name Messstelle Beschreibung Motor Bedingung Grenzwert Hysterese Delay 名称 测量点 说明 机型 条件 设定值 滞后 延时 Splash oil油雾温度 alarm报警 1TAH2880 xTE2880 LV32/40CD 95?C,H -1K 1.7s splashoil temp high油雾温度高 auto shutdown自动停车 2TZH2880 xTE2880 LV32/40CD 100?C,H -1K 1.7s splashoil temp high油雾温度高 alarm报警 1TDAH2880 xTE2880 splashoil temp mean value deviation LV32/40CD +4K,H -1 K 1.7s 油雾温度平均偏差值 auto shutdown自动停车 2TDZH2880 xTE2880 LV32/40CD +6K,H -1 K 1.7s splashoil temp mean value deviation 油雾温度平均偏差值 WAGO release of splashoil monitoring stand-alone 油雾温度监测释放 1TSH2880 xTE2880 LV32/40CD 73?C,H -3 K 16s splashoil splashoil temp mean value OK 独立应用的油油雾温度平均值正常 雾温度 HT Cooling Water高温冷却水 external alarm报警 1PAL3170 1PT3170 LV32/40CD 1.8 bar,L 0.1 bar 4s HTCW pressure engine inlet low HTCW pump高温冷却水进机压力低 机外高温水泵 external auto shutdown自动停车 2PZL3170 2PT3170 LV32/40CD 0.1 bar 4s HTCW pressure engine inlet low HTCW pump1.5 bar,L 高温冷却水进机压力低 机外高温水泵 alarm报警 1TAL3170 1TE3170 LV32/40CD 55?C, L 5K 2s HTCW temp engine inlet low 高温冷却水进机温度低 alarm报警 1TAH3180 1TE3180 LV32/40CD 95?C,H -2K 2s HTCW temp engine outlet high 高温冷却水出机温度高 auto shutdown 自动停车 2TAH3180 2TE3180 LV32/40CD 98?C,H -2K 2s HTCW temp engine outlet high 高温冷却水出机温度高 LT Cooling Water低温冷却水 alarm报警 1PAL4170 1PT4170 LV32/40CD 1.2 bar,L 0.1 bar 4s LTCW pressure low 低温冷却水压力低 Fuel燃油 alarm报警 1PAL5070 1PT5070 LV32/40CD 4.0 bar,L 0.1 bar 4s fuel pressure low燃油压力低 Exhaustgas Temperatures废气温度 alarm报警 LV32/40CD 510?C,H -5 K 30s 1TAH6570 xTE6570 exhaust gas temp after cyl.
