They come in R2 or AS cases, maintaining the advantages of withdrawabilty and strength ofthis type of relay, and ft perfectly into the PROCOM architecture. The 700 series is made up of: athe AMS711 ‘overcurrent, single phase (phase or earth faut) the RMS761 overcurrent, three phase the RMS771 ‘overcurrent, two phase and earth faut athe RMS731 overcurrent, three phase and earth fautt he TMS711 under/over vottage, single phase -the TMS761 under/over voltage, three phase the TMS714 neutral displacement over voltage. ‘The RMS700 has two wide setting range current thresholds: -dependent (inverse) or definite time low set -definite time high set ‘On the RMS771 and the RMS731 the setting and the choice of the curve for the avercurent and the earth fault elements are independent of each other. ‘On the TMS700, each of the 2 voltage thresholds may be set independently to under or over voltage, with dependent or definite time response curves. Series 700 relays ere equipped with three output relays: one from the seff supervision watch dog - “the other two associated with the various instantaneous or time delayed thresholds. “The latter are each provided with two contacts: one NO and the other NO or NC, depending upon the relay model Omthe RMS771 and the RMS7S1 the A and B output relays are programmable: “Overcurrent and earth faut, ow sets on A / high sets on 8 oR Low set and high set overcurrent on AJ low set and high set earth fault on B ‘On the AMS711, RMS761, A is connected to the low set and B to the high set nthe TMS711, TMS761, TMS714 A is connected to threshold 1 and 6 to threshold 2 Operation of the relay is memorised and signalled by the flashing of the electroluminescert display ‘The relay has a current loop communication port and fits into the PROCOM netwark. 4.2 COMMUNICATIONS Series 700 relays communicate with the autside world in two ways: -Local communications: The man machine interface is provided by a 4-key keyboard-on the relay front plate; this allows the device to be set and measured values to be read, This information is read on the high contrast electroluminescent cisplay.
