Figure 1: Schuki 2 Control elements Two elements available for testing the ELCB circuitry. y (S1) Rotary switch to adjust the nominal fault current y (T) A button to trigger the nominal fault current The touch electrode tests the phase conductor according to the principle of a phase tester. Symbols used in this documentation To provide a better overview, images are used to enhance the descriptions of faults. For this purpose, the following symbols are used: y Symbol not shaded: The lamp is not glowing or the button has not been pressed y Symbol shaded: The lamp lights up or the button has been pressed y Plug symbol for test results: The recognised circuitry is portrayed. y Danger symbols: The recognised circuit is a danger to life. Schuki 2 22.01.2004 15:49 Uhr Seite 1417 Figure 5: The lamps L1 and PE light up. Touching the touch electrode has no effect. The phase conductor is connected to the earthing contact! No neutral conductor, Phase and protective earth have been reversed. No protective earth Figure 6: The lamps L1 and N light up. GL1 lights up when the touch electrode is touched.

Fault indication No current flowing None of the lamps light up. Touch the touch electrode as well. Should none of the lamps light up, the phase conductor is not connected. If one of the lamps in the yellow area glows, then the phase conductor is connected to the respective connection. Device plugged incorrectly Figure 4: The lamps L1 and PE light up. GL1 lights up when the touch electrode is touched. You must observe the fault depicted in figure 5. Figure 3: The lamps N, L1 and L2 light up. When the touch electrode is touched, the lamp GL1 does not light up. The phase conductor is not contacting the left-hand pin of the test device (viewed when device is inserted and faceplate visi- ble); it cannot be tested. Rotate the Schuki 2 180° and re- insert. No neutral conductor Schuki 2 22.01.2004 15:49 Uhr Seite 1619 Figure 9: The lamps L1, PE and N light up. Touching the touch electrode has no effect. This is a typical fault in older installations with classic ‘protec- tive multiple earthing’, if the phase and protective earth con- ductors have been reversed. The phase conductor is connected to the earthing contact! Open neutral, phase conductor connect- ed to earthing contact

Phase and PE conductors have been reversed Figure 7: Lamp L2 only lights up. Touching the touch electrode has no effect. This fault configuration is indicated when the testing device has been incorrectly inserted. The phase conductor is connected to the earthing contact! Figure 8: The lamps N, L1 and L2 light up. GL1 lights up when the touch electrode is touched. This is a typical fault with older installations with classic ‘pro- tective multiple earthing’, if the phase and protective earth conductors have been reversed. The phase conductor is connected to the earthing contact! No protective earth, phase conductor connected to earthing contact Schuki 2 22.01.2004 15:49 Uhr Seite 1821 Figure 11: All lamps in the yellow area light up. In addition, L3 lights up when the button T is pressed; simulta- neously the PE lamp goes out. The lamps go out when the ELCB is tripped. The protective earth conductor has an increased but permissi- ble resistance. Earth wire resistance is still permissible

Testing the ELCB protected circuit Insert the testing device into a socket outlet and test the cir- cuitry. If no fault is indicated, you can begin testing the ELCB function. Using the switch S1, adjust the nominal fault current to the required value; press the button T. The nominal fault current flows for 200 ms. Note: y This test can also be carried out in systems not fitted with an ELCB. y It is permitted to press the button T once every 10 seconds only. No fault determined Figure 10: All lamps in the yellow area light up. In addition, the lamp L3 lights up when the button T is pressed. The lamps go out when the ELCB is tripped. Please refer to the first fault indication FI, if the ELCB is not tripped.
