General functioning of the room automation station The ecos401 intelligent unitary controller is a microprocessorassisted, configurable controller used to control and regulate a varied range of HVAC applications on the basis of LON technology The ecos401 intelligent unitary controller uses the LonTalk communication protocol and is LonMark -certified if the sensor profile (number 1) is used for the relevant input objects and if the actuator profile (number 3) is used for the relevant output objects The ecos401 intelligent unitary controller supports LonMark profile #8020 The integrated operating programme can be programmed freely with the help of a plug-in; it reads in the hardware and software addresses, processes the user programme, updates the outputs and handles the necessary communication with other stations in the network or with the management level The user program can be loaded from any point in the LON network using SAUTER CASE LON Engine The plug-ins can be used to parameterize the controllers with the SAUTER CASE LON Engine network management tool or via any LNS-based software, according to choice Engineering notes Installation and wiring The ecos401 intelligent unitary controller can be fitted in an MCC using a top-hat rail (EN 50022) Wall-mounting is possible, using the fitting holes in the lower housing It is possible to separate the upper and lower sections of the housing in order to install and connect the automation station The plant devices are connected via screw terminals The following conditions must be met: Cross-section conductors: LON network: of min 082 mm 2 (AWG 18), max 2 mm 2(AWG 13), compliant with standards and national installation regulations min 065 mm 2 (AWG 22), twisted and unscreened Suitable network terminations (terminators) must be used for different network topologies Failure to comply with the specified requirements may cause transmission errors between the controllers The use of different cable cross-sections in one network section is not permitted Detailed guidelines on planning and installing twisted-pair LonWorks networks have been published by the Echolon Corporation Connections: LON network: 2 (jack plug, mono, 1/8" / 35 mm) Earth terminals: 9 I/O terminals: 13 LS-MM terminals: 24 V ~ Hardware: The ecos401 intelligent unitary controller comprises: Processor Memory Communication Channel Status indicators Neuron 3150 ; 8 bit; 10 MHz Non-volatile 64 kb flash memory (APB and programme application) LonTalk protocol TP/FT-10; 78 kbit/s Green LED: Power supply status and LON-TX Orange LED: Operation and LON-RX Description of inputs and outputs The ecos401 intelligent unitary controller has 6 universal inputs and 2 universal outputs 5 Triac outputs are also available in each case All the inputs and outputs must be configured via software The input resolution is 16 bits and the output resolution is 10 bits The inputs and outputs may be used as follows: Input Temperature sensor: Potentiometer: Current: Voltage: Digital: Pulse: NTC, Pt 10 k, 100 k 0 20 ma (4 20 ma) 0 10 V Potential-free contact Potential-free contact Output Voltage 0 10 V= Digital: 0 12 V=, (I/O) PWM The sampling period for the inputs is 1 s if they are configured as voltage, potentiometer or temperature inputs, and 500 ms for configuration as digital inputs The UIx inputs can take a maximum load of 24 V Technical specifications of inputs and outputs Temperature measurement (NTC, Pt) The Pt1000 sensors are connected using the two-wire method between one of the input terminals for a universal input (UI01 UI06) and an earth terminal In case of an NTC/Pt connection, the inputs do not require calibration and can be used directly The connected sensor type and the desired offset input are chosen in the software NTC type 2, 10 k Accuracy: ± 05 C NTC type 3, 10 k Accuracy: ± 05 C Circuit Period duration Value Short-circuit/ override *) < 5 s > 5 s > 15 s Override = on Override = off Input = +1999 Open - -1999 PT1000, 1 k Accuracy: ±1 C PT100, 100 k Range: -40 135 C Accuracy: ±1 C Circuit Period duration Value Short-circuit/ override *) < 5 s > 5 s > 15 s Override = on Override = off Input = +1999 Open - -1999 *) If the input is short-circuited, this may be interpreted as an override, ie the relevant control loop is switched from "unoccupied" status to the "occupied/override" operating mode Potentiometer measurement (Pot) It is possible to use the input in combination with a potentiometer if a 10 k or 100 k resistance is used For configuration purposes, the resistance value can be limited and scaled to any desired value range in C A potentiometer is connected between an input terminal of a universal input (UI01 UI06) and the associated earth terminal The measurement accuracy is ± 05% 2/5 wwwsauter-controlscom
Current measurement (I) The current to be measured is connected to the input terminals of the universal inputs (UI01 UI06) between UIx and earth The signal must be potential-free In order to use the current input on the ecos401 intelligent unitary controller, either a supply of current to the sensor or a parallel input-sensor supply is required An external voltage source or the integrated 15 V= can be used for this purpose A 249 resistance must also be connected in parallel with the input The input is defined as a 4 20 ma input by default To adapt the input to 4 20 ma, the minimum value must be configured as 4 ma in the software Voltage measurement (U) The universal inputs (UI01 UI06) are used to measure voltage The voltage input has a range of 0 10 V The connection is made to an input and the associated earth terminal The voltage signal must be potential-free The input can be adapted to different ranges via software Parameters "min", "max" or "offset" are available for this purpose Digital inputs (DI) All universal inputs (UI01 UI06) can be used as digital inputs and must be connected to earth Type of inputs: Potential-free contacts, connected to earth Opto-coupler Transistor (open collector) Digital information is connected between the input terminals (UI01 UI06) and earth The station applies a voltage of approx 13 V to the terminal In normal cases (NORMAL) this corresponds to INACTIVE (bit=0) for an open contact When a contact is closed it is ACTIVE (bit=1) and 0 V is applied, whereby the current flow equates to approx 1 ma For each input, it is possible to define the "on" and "off" values individually, as well as the direction of operation (normal or reverse) Universal outputs The universal outputs (UO06 and UO07) can be configured as voltage outputs, via the software The output voltage is measured between the relevant output terminal and an earth terminal (UOx, Com) Type of output 0 10 V= max 60 ma to earth Digital output (DO) Alternatively, the universal outputs (UO06 and UO07) can be configured as digital outputs A discrete output signal is issued: 0 V= for OFF and 12 V= for ON If a relay is triggered via the universal output, a diode (1N400x family) must be connected to the connection terminals in parallel This protects the output against voltage peaks when the relay cuts out If the universal outputs are configured as PWM outputs, the period duration can be set between 2 s and 15 min The period duration can be set between 0 and 100% of the "on" duration Loading capacity of the output: Max 20 ma at 12 V= max load 600 The output is fitted with a self-resetting fuse Maximum power load: 60 ma at 60 C 100 ma at 100 C Parameterisation of the intelligent unitary controllers variables The controller software supports structured SNVTs and UNVTs of 1 and 2 bytes in length 16 NVIs and 20 NVOs (with changeable types and lengths) are available User programme Simple configuration of all device parameters, including inputs, outputs, ventilator and fan settings, and setpoints for heating and cooling It is also possible to parameterise additional integrated functions such as optimal start/stop procedures, load shedding, frost protection and slave operating mode Triac outputs (DO) 5 digital (UO01 UO05) Triac max 10 A at 24 V~ External power supply with external fuse (fast-blow 4 A fuse with high cut-out power) One earth per output wwwsauter-controlscom 3/5
