Individual, demand-led ventilation of individual rooms is possible in relation to the room occupancy, room temperature or the CO2 content of the air. The volume flow passing over the volume flow box is measured with an integrated static differential pressure sensor and is compared with the volume flow setpoint specified by the controller. If the actual value deviates from the setpoint, the volume flow over the volume flow box is adjusted by means of the integrated damper drive until the required setpoint is attained. The inputs and outputs provided may be used for a variety of applications. The ecos416 volume flow 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 ecos416 intelligent unitary controller supports LonMark ® profile #8502, Space Comfort Controller - VAV. 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 volume flow controller can be fitted directly on the damper shaft of the volume flow box with the servo-motor. Another fixture on the housing of the volume flow controller functions as a counterbearing; this fixture is connected to the volume flow box. The plant devices are connected via screw terminals. The following conditions must be met: Cross-section conductors: LON network: of min. 0.82 mm 2 (AWG 18), max. 2 mm² (AWG 13), compliant with standards and national installation regulations. min. 0.65 mm² (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" / 3.5 mm) Earth terminals: 4 I/O terminals: 10 LS-MM terminals: 24 V~ ± 15%, 55 Hz 300 mA (7.2 VA) with 24 V~ Room operating unit: 2 (SMRT +/-) Hardware: The ecos416 intelligent unitary controller comprises: Processor: Neuron ® 3150 ® ; 8 bit; 10 MHz Memory: Non-volatile 64 kB flash memory (APB application and programme) Communication: LonTalk ® protocol Channel: TP/FT-10, 78 kbps Status indicators: Green LED: Power supply status and LON-TX Orange LED: Operation and LON-RX Differential pressure sensor: Measuring range: Measurement accuracy: Damper drive: Torque: Running time for 90°: Static sensor with piezo-resistive recording of measured values 2…250 Pa ± 3% in relation to the entire measurement range (FS) Brushless DC 4 Nm 120 s Description of inputs and outputs The ecos416 intelligent unitary controller has 4 universal inputs and 2 universal outputs. 4 Triac outputs are also available. 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: Ni1000, NTC, Pt 10 k, 100 k 0…20 mA (4…20 mA) 0…10 V 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 current, voltage, potentiometer or temperature inputs, and 500 ms for configuration as digital inputs. The UIx inputs can take a maximum load of 24 V. 2/5 www.sauter-controls.com
EY-RC416 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…UI04) and an earth terminal. In case of an Ni/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 Range: -40…150 °C Accuracy: ± 0.5 °C NTC type 3, 10 k Range: -40…150 °C Accuracy: ± 0.5 °C Circuit Period duration Value Short-circuit/ override *) < 5 s > 5 s > 15 s Override = on Override = off Input = +199.9 Open - -199.9 PT1000, 1 k Range: -40…150 °C 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 = +199.9 Open - -199.9 *) If the input is short-circuited, this may be interpreted as an override, i.e. 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…UI04) and the associated earth terminal. The measurement accuracy is ± 0.5%. Current measurement (I) The current to be measured is connected to the input terminals of the universal inputs (UI01…UI04) between UIx and earth. The signal must be potential-free. In order to use the current input on the ecos416 intelligent unitary controller, either a supply of current to the sensor or a parallel input-sensor supply is required. An external voltage source of 24 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…20mA input by default. Voltage measurement (U) The universal inputs (UI01…UI04) 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…UI04) 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…UI04) and earth. The controller 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 (UO05 and UO06) can be configured as voltage outputs, via the software. The output voltage is measured between the relevant output terminal and an earth terminal (UOx, 5- 6). Type of output: 0…10 V= max. 60 mA to earth Digital output (DO) Alternatively, the universal outputs (UO05 and UO06) 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 Triac outputs 4 Triac Max. 1.0 A at 24 V~ per Triac The jumpers on the controller must be changed over in order to use the internal 24 V supply. If the power supply is used internally, it is protected with a 3 A fuse. If the internal power supply is used, an AXT111F202 can be controlled via the 24 V output in combination with a Triac. For an application with two AXT111F202s for heating and cooling, it is only possible to operate one AXT111 in each load case. The internal heating-cooling sequence prevents the simultaneous operation of two AXT111F202s. www.sauter-controls.com 3/5
