Product Details

Product description Monitoring of insulation resistance of ungrounded voltage systems to earth.IL/SL 5880/200 can also be used to monitor standby devices for earth fault, e.g. motor windings of devices that have to function in the case of emergency.IL/SL 5880/300 according to DIN VDE 0100-551 to monitor mobile generator systemsOther resistance monitoring applications.For industrial and railway applicationsFeaturesAccording to IEC/EN 61557-8For single and 3-phase AC-systems up to 0 ... 500 V and 10 ... 10000 HzAdjustable tripping value RAL of 5 ... 100 kΩ or 10 ... 500 kΩMonitors also disconnected voltage systemsDe-energized on tripAuxiliary voltage Measuring Circuit and output contacts are galvanically separatedManual and auto resetWith test and reset buttonConnections of external test and reset buttons possibleLED indicators for operation and alarm2 changeover contactsIL/SL 5880/200 with additional prewarning- adjustable prewarning value 10 kΩ ... 5 MΩ- output function programmableVariant IL/SL 5880/300 according to DIN VDE 0100-551 for mobile generator sets available4 models available:IL 5880, IP 5880: 61 mm deep with terminals near to the bottomto be mounted in consumer units or industrial distribution systems according to DIN 43 880SL 5880, SP 5880: 98 mm deep with terminals near to the top to be mounted in cabinets with mounting plate and cable ductsDIN rail or screw mounting35 mm widthFunctions :The device is connected to the supply via terminals A1-A2. The unit can either be supplied from the monitored voltage system or from an sepa-rate auxiliary supply. Terminal L is connected to the monitored voltage and PE to earth. If the insulation resistance RE drops below the adjusted alarm value RAL the red LED goes on and the output relay switches off (de-energized on trip). If the unit is on auto reset (bridge between LT1-LT2) and the insulation resistance gets better (RE rises), the insulation monitor switches on again with a certain hysteresis and the red LED goes off. Without the bridge between LT1-LT2 the Insulation monitor remains in faulty state even if the insulation resistance is back to normal. (In order to achieve failure storage, the voltage system showing a fault must not be switched off too fast after detection of the failure, see notes). The reset is done by pressing the internal or external reset button or by disconnecting the auxiliary supply. By activating the "Test" button an insulation failure can be simulated to test the function of the unit.The variants IL/SL 5880.12/200 have a second setting range with a higher resistance up to 5 M??? (Potentiometer RVW). This setting value can be used for pre-warning with relay output, by positioning the lower setting switch to "AL 11-12-14; VW 21-22-24".If the higher setting range should be used only, the setting switch is put in position "VW 2u" and both contacts react only to the higher setting.If the lower setting range should be used only, the setting switch is put in position "AL 2u" and both contacts react only to the lower setting.When set to manual reset the latching is active on both settings RAL and RVW. Therefore it is possible in the case of a short insulation decrease (Switch position AL 11-12-14; VW 21-22-24), to pass the warning signal to a PLC while the main fault does not lead to a disconnection of the mains via the contacts 11-12-14
