A PAGE 10 / 24 4 ELECTRICAL INTERFACES OF COMPONENTS This chapter describes the electrical interfaces of the electrical components and their functionality. For testing these components they are connected to the test cabinets, which will be qualified, too. They provide all the needed interfaces. For testing these cabinets, an additional test cabinet is built. This cabinet provides the interfaces to test the cabinets. For differentiation between the different cabinets the following designation is used. The cabinets, which will be qualified are called testee cabinets, the cabinet which will provide the test functions is called tester cabinet.

DTC compressor feeding N° A3X-900.964 Definition of the hardware configuration for EMC tests REV. A PAGE 12 / 24 Fig. 2. DTC compressor signal interface The Danfoss Turbocor compressor consists of two parts. The compressor is fed by a 400 V power supply. The control section is done via interface module and consists of two control signals and two feedback signals. A 0 to 10 V analog demand and a digital interlock contact. The feedback signals are two digital potential-free contacts, a running and a fault message. N° A3X-900.964 Definition of the hardware configuration for EMC tests REV.

RTK valve signal feedback The Expansion and Hot-gas bypass valves (RTK valve MV5314-K) consist in general of three parts. First, there is the control of the valve. With connecting 230 V AC to the terminals 7 and 5 for opening respectively 10 and 5 for closing, the valve can be operated. Second, there is the analogue feedback. This feedback has to be supplied by 24 V DC on terminal 1. Via terminal 2 and 3 a 4 to 20 mA signal is sent to back that shows the position of the valve. Last, there is the digital feedback, the limit switches. Via two potential-free contacts, a feedback is provided, that shows if the valve is completely open or closed. A closed valve is signalized if switch between the terminals 19 and 20 is closed, an open valve is signalized by the terminals 16 and 17.

The same is done for the 0(4) to 20 mA outputs. 4.8.7 Testee cabinet internal inputs Internal inputs (e.g. MCB feedback) cannot be simulated from external signals. For checking if they work automatically, the signals will be subsumed inside the testee PLC and sent to the tester cabinet by one of the digital outputs. 4.8.8 400V / 690V supply The supply for the cabinet will be provided by the laboratory. 4.8.9 PLC response test For testing the general PLC response an additional test is foreseen in which the analogue and digital in- and outputs are tested, including response time testing. For these tests, the in- and outputs of the testee PLC are directly connected to the in- and outputs of the tester PLC via their front connect
