M Littelfuse RoV. T Pagc 1 PGR-2601 DC EyNQ-rault Relayoo 1 GENERAL The PGR-4801 a microprocessor-based ground-fault monitor for ungrounded dc systems.<is onput relay can operate in the fail-sate or non fail-safe mode forgadervoltage or shunt-trip applications. The PGR-2601 has one output relay win isolated normally open and normally closed contacts for use in independent control circuits. Additional features include led power and 即。∠ 100 200 40.0 622 6 5 30 7.9 158 492 2.0 10.6 21.3 329 10 C.7 14 37 75 15 232 15 0.3 0.6 1.6 3.3 6.7 10.2 20 0.1 0,2 06 2,5 2.23 Reset If the Reset Made switch is in the Latching position a trip remains latched until the REsEt switch is pressed or the remote-reset terminals are momentarily connected. In the non-fail-safe mode, Cycling the supply voltage will also reset the pgr 2601 If the Reset Mode switch is in the AUTORESET position, a tip will reset when the fault is removed The reset circuit responds only to a momentary closure so that a jammed or shorted switch will not prevent a trip. The front-panel RESET switch is inoperative when the remote-reset terminals( 6 and 7)are connected z24 Test The tEST switch is used to test the ground-fault circuit trip indication, and the output relay, When the TEST switch is pressed for one second, a test signal is applied to the ground fault-detection circuit, the circuit will trip, both BUS andt BUS TRIP LED's will light and the oulput relay will operate 23 Frontpage indication 2.3.1 Power 1) The green LED labeled PWR indicates presence of the supply voltage 2327jp The TRIP LED's indicate a ground-fault trip. The "BUS" TRIP LED indicates a ground-fault on the negative dc bus. The BUS" TRIP LED indicates a ground-fault on the positive dc bus. Two fast flashes indicate a diagnostic trip. See Section 2.5 d凸2rrr 叫ts 尺ev.1 尸 se PGR-200AD83urid-Fault Relay C 2.5 Self DDts Aragnoslc trip is indicated by tw Hashes of the TRIP LED'S. It can be aused'by a diagnestieoslen detected by the watchdog timer or from an incorrect-reaaingdiinon-volatile memory.
