단열재 monitor for pure 3 phase and alternating current systems, AI897. Adjustable response value 10 ??80 kΩ No separate auxiliary voltage connection required 1 changeover Overall width 45 mm. The AI897 insulation monitor displays the insulation resistance of unearthed 3 phase and alternating current systems to earth. The device works according to the quiescent current principle, that is, the output relay responds when mains voltage is applied to terminals A1 ??A2. The output relay breaks when the response setpoint is undercut. A bridge between terminals LT1 and LT2 allows the AI897 to be programmed for memory storage behaviour; remove the bridge to programme hysteresis behaviour. The bridge can be replaced with a delete key with an NC contact. There is a PT test button on the front of the device to test for functional efficiency. An external test button (in accordance with VDE 0413) is also possible.
