The voltage present in the system is used to drive the test current.The value of the test current which is generated therefore depends on the value ofthe insulation fault that is present, and on the system voltage. The test current islimited to a maximum of 2.5 mA or to 1 mA when the switch is under the 1mAposition.The test current flows from the system via the PGH183 and then through theprotective conductor (PE) and the insulation fault (or faults) back to the system. Thetest current signal is detected by the current clamps or measuring currenttransformers located in the fault current circuit, and the defective circuits areindicated by the EDS165-3 insulation fault evaluator whenever the response value of0.5 mA is exceeded.If the PGH183 is active, the cycle LEDs light up alternately in time with the testcycle. If the device is connected by terminals L1, L2, L3 (or L1, L2) to a system that islive for operational reasons the terminal must not be disconnected from theprotective conductor (PE).AttentionThe test current flows between the system and earth. If unfavourable combinationsof circumstances arise (low-impedance insulation fault in combination with the testcycle), control errors cannot be ruled out on very sensitive system components (SPC,miniature relays). This possibility should be taken into account prior to use. If thispossiblity exists, then setting I max= 1 mA should be selected.18TGH1320E/03.2000
