2 LISTEC ® GmbH Design and Principles LIST System Karlheinz Tank Mai 2014

3 Basic LIST system SEC 20, CBO and LISTcontroller

4 LISTcontroller Housing 19“ 1U rack Power supply24 V DC DisplaysLEDs, LCD Processors3 Memory for lists Non-v olatile Timer RTC (Goldcap) Interfaces4 (2x RS232, RS485, LAN) Cable lengths3.200 m (+ max. 300 m connection line) Sensors320 Groups254 Group relays256 Redundance / LoopYes LISTcontroller

5 Cable design SEC 20 Cable jacket Aluminum shield Filler material Sensor Flexible flat cable Strain relief

6 SEC 20 Cable design 4 wires Sensor spacing min. 0,5 meter Standard spacing2, 4, 5, 8 and 10 m Measuring range -40 °C to 85 °C Sensor cable weight0,45 kg/m Connection At the beginning of each single sensor cable, a connection box shal be provided, in which the connectioncable connects the Listcontroller to the sensorcable via CCM connection module.

9 Measuring cycle Set alarm relayProtocol output Evaluation Alarm? Read Temperatures Test Measurement

10 Addressing / Data reception SEC 20 Digital addressing Analog data

11 Addressing - Advantages Branchable Bidirectional No termination necessary Free numbering System with different sensor distances possible

12 Test - Plausibility Validity of temperatures Temperature jumps

14 Alarm evaluation: Reference profile Reference value adjustment / sensor for ambient temperatures with normal temperature development. Current temperatureReference temperature Measuring Cycle Temperature (°C)

15 Alarm evaluation: Differential temperature alarm Quick rise of environmental temperature leads to differential temperature alarm.   Pre-signal  HEATING Alarm  FIRE! - DT - Reference Temp. - Current Temp.
