EARTH-FAULT INDICATOR TYPE EASI - 1

DATA SHEET EARTH-FAULT INDICATOR TYPE EASI surface-mounted General description The earth-fault indicator type EASI can be used in radial networks with one input and open-ring networks which are solidly earthed or low resistance-earthed. The EASI is available in two versions: EASI: indication of an earth-fault by one LED EASI-R: indication of an earth-fault by one LED and one flag indicator The indicator set consists of one display unit and one sensor (CT). The connection between the earth-fault sensor and the display unit is done by cable. The sensor must be mounted on screened cables. The sensor is divisible and can be retrofitted on the cable. The earth fault indicator detects the earth fault by measuring the sum current of the monitored network with one sensor (CT). Features and options Permanent earth-faults: Remote Reset and Test: Power supplies: Push button: Sensor reset: Optional reset input: Optional inrush current filter: Indication of permanent earth-faults by double blinking of the earthfault LED. Device can be remotely resetted and remotely tested through one external contact. lithium battery (LiSOCl2) type AA / 3.6V / 2600 mAh Optional: 10-110 V DC or 110 / 230 V AC power supply with optional lithium backup battery Push button on the side of the housing Optional: push button on the front of the housing Automatic reset on recovering net current For reset by recovering external power supply Suppression of inrush currents up to 3 seconds (custom value can be ordered, 230V AC input required.) earth-fault sensor (CT) remote reset/test external blinking lamp (Type BL4.1 + BL6) SCADA contact NO SCADA contact NC external power supply ELEKTRO-MECHANIK EM GMBH Ringstr. 4 - D-42553 Velbert / Germany Tel: +49 2053 422890 - Fax: +49 2053 422899 www.emg-ger.com
