Transcription

1 GFX- LOOP MODULAR POWER CONTROLLER Main features independent loop control unit. Compact, ready to use, equipped also with fieldbus interface. Main application Packaging Extrusion Thermoforming Injection moulding Textile Multizone furnaces Unit consisting of: Controller 30, 60, 80kW solid state relay Current transformers (one or four) Fuses-holder (option) universal main inputs heat/cool independent PID main output internally wired to the SSR auxiliary analog inputs (option) configurable output (option): relay / logic / TRIAC / continuous configurable relay alarm output digital inputs Standard digital communication: Modbus RTU Optional Fieldbus communication: Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP DIN rail or panel mounting PROFILE GFX is a four independent loop controller, designed to manage electrical power. GFX is a compact unit bounding different techlogical elements like: controller solid state relay current transformers fuses-holders (option) The final result is a cost saving in terms of space and cabling. GFX consisting of: power management unit analog and digital inputs, analog and digital outputs standard digital communication integrated solid state relays fuses-holder (option) Geflex controls automously the four loop controllers, furnishing a complete diagstics like the loaded current, the control of the zones, the alarms state. A specific step by step software tool has been develop in order to assist the product configuration based on the different applications. Communication with the outside is of primary importance. Geflex dialogs with the operator terminals according to the most popular protocols: from the simple and efficient Modbus to, by a second optional fieldbus communication, the by-w indispensable Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP. The product s furnished with a standard configuration, simple and quickly to modify. The assignment of different functions to the outputs is very simple. MODELS (see table in order code) 3 different sizes, depending on the electric power managed, are available. GFX 80 Maximum contemporaneous power up to 80kW@V. Each zone could reach up to 9, kw. This limit could be extend to 3,7 kw using the smart power management (t all the zone contemporaneous). Nominal current 0A for zone, t contemporary maximum 57A GFX 60 Maximum contemporaneous power up to 60kW@V. Each zone could reach up to 5,3 kw. Nominal current 3A for zone Fuse holder could be provide as an option. GFX 30 Maximum contemporaneous power up to 30kW@V. Each zone could reach up to 7,6 kw. Nominal current 6A for zone Fuse holder could be provide as an option.

2 INPUTS Process analogue universal process input could accept: thermocouple, thermoresistance, current and tension linear. The type could be choose by software and external converting device are required. Digital digital input. The functionality could be selected within a wide range including setpoint selection, MAN/AUTO, alarm memory reset and many other. Incorporated CT From to CT control each zone and the relative alarm control is start up (HB..). Auxiliary analogue (option) further analogue inputs are available, typically for external current transformer reading. OUTPUTS Output alarms configurable via software. Heating control For each zone an heating control internally connected to power unit is present, then further connections needed between power unit and controller. Cooling control (option) For each zone a cooling control is present types of outputs are available: relay, logic, triac, continuous. A current transformer is furnished with TRIAC output. Alarms Two relay output configurable as minimum and maximum alarm are available for each unit. LEDS Eight monitoring led are available in order to provide diagstic information. RN RUN stet of the CPU ER Error DI DI digital input state DI DI digital input state O Outupt state O Outupt state O3 Outupt 3 state O Outupt state By default a different meaning is applicable. POWER Power is controlled with double SCR in anti-parallel, zero crossing switching principle, with configurable proportional cycle time. Different load connection are available: mophase, dualphases, three-phases. FUSES (OPTION) The fuses are orderable on the GFX 30KW and 60kW model. Thanks to this, you save time, wiring is simplified, and dimensions in the panel are reduced. PROGRAMMING The Geflex modules can be programmed: using GFX-OP using Winstrum tool software using Industrial PC or PLC. FUNCTIONS Control The Geflex control algorithm works with any type of thermal process. Different control modes are available: from a simple ON/OFF control to PID single or double acting heat/cool (for cooling, simply indicate the fluid used). Sophisticated and efficient automatic tuning algorithms for control parameters provide precise process control without the presence of an operator. Alarms There are 8 alarm assignable to each single canal or to all (AND / OR logic) and configurable as absolute, relative, direct, reverse, window, latching or t, inhibit at power-on. Diagstics Geflex assures efficient process monitoring from a thermal and electrical point of view, allowing the operator to foresee breakdowns or malfunctions and take timely action (for example, in case the temperature safety limit is exceeded, broken probe, load fault). The LBA alarm precisely checks the control loop, while the on-board current transformer (one always present, four available in option) lets you directly monitor load and trip the HB alarm in case of current failure or SSR in short circuit. Detection of short circuit or opening of input probe, open loop alarm (LBA), interrupted load alarm (HB). Over temperature alarm The software can be used to define the state of alarm outputs or a preset power level to be supplied in case of broken probe. This assures continuity of service in the individual zone. Tuning Self-tuning: calculation of PID parameters at system art. Auto-tuning continuous: continuous adjustment of PID Autotuning one-shot: output modulation and event-driven automatic PID parameters re-calculation Special functions Soft-start: power parcellization timebased Software Off: disabling of the control, outputs are turned off Inputs\outputs: direct management of inputs/outputs, independently from internal firmware Simulation of four independent Geflex units. STANDARD DIGITAL COMMUNICATION The product is furnished with standard digital communication [PORT ] used as GFX connection to a HMI or Industrial PC. Also by a dedicated connector (0 pins) it s possible to connect the actual range of Gefllex. A second standard digital communication (PORT ) configurable by most popular protocol: CANopen DeviceNet Profibus DP Modbus RTU Ethernet Modbus TCP is available as option. Net address Assigned by two rotative selectors.
