3.3 Output of loop frequency Approx. 1 sec. after calibration of the detector the loop frequency will be displayed by pulse signals of the green LED. Firstly the 10kHz position of the frequency value will be indicated. For every 10kHz frequency value the green LED flashes once. After a break of 1sec the 1kHz position is displayed in the same manner. If there is value of '0' in the 1kHz position there will be displayed 10 flashes. The flashes for 1kHz position are a little bit shorter than for the 10kHz position.Example for 57kHz loop frequency:tenth valuessingle values1sec5x 10kHz7x 1kHz4 Connectionsdescription powerrelay 1relay 2loop 1 and loop 2connection 0V 24V 1a 1b 2a 2b 4-pole connection jack5 Technical dataDimensions Protection class79x22.5x90 mm (h x w x d without plug) IP 40Power supply24V AC/DC ±10% max.2,0WOperating temperature Storing temperature Humidity20 °C to +70 °C -20 °C to +70 °C max. 95 % not condensingLoop inductivity Frequency range Sensitivity
