3 Function and system design Measuring principle The Nivotester FTR325 monitors the Soliwave M microwave barrier s open collector output and uses a relay (change-over gate) to provide this output for many user applications. An LED displays the switching state of the relay. Problems such as a cable breakage are also displayed. The input on the Nivotester FTR325 is galvanically isolated from main power and output. It is connected to the microwave barrier via a three-wire cable (ring or star wiring), whereupon the Nivotester provides distribution (DC) voltage to the microwave barrier. Limit switch signal function The appropriate setting for the limit switch signal function (see page 8) ensures that the relay for signal output and fault is always activated (fail-safe mode) in idle state. In combination with the Soliwave M microwave barrier the following secure modes are possible: The relay drops out when the switch point is reached (microwave barrier interrupted), a fault occurs or the distribution voltage fails. The relay drops out when the switch point is underrun (microwave barrier uninterrupted), a fault occurs or the distribution voltage fails. Function monitoring system The Nivotester FTR325 is equipped with function monitoring system for improved fail-safe operation. A fault is indicated by an LED, the signal output and fault relay falls off. In combination with the microwave barrier Soliwave M FQR50/FDR50-A* (non hazardous area) and -B* (ATEX II 1/2 D) respectively the Nivotester FTR325-A* (non hazardous area) can recognise the following faults and use an LED to indicate them: Breakage in the distribution voltage cable to the microwave barrier Microwave barrier power input (emitter FQR50 and/or receiver FDR50) too high Short-circuit (emitter FQR50, receiver FDR50 or wiring) In combination with the microwave barrier Soliwave M FQR50/FDR50-C* (ATEX II 1/2 GD) the Nivotester FTR325-B* (ATEX II (1) GD) can recognise the following faults and use an LED to indicate them: Breakage in the distribution voltage cable to the emitter FQR50 Microwave barrier power input (emitter FQR50 and/or receiver FDR50) too high Short-circuit (emitter FQR50, receiver FDR50 or wiring) Manual function monitoring can be carried out by pushing the test button. 3
