Geflex controls autonomously the four loop controllers, furnishing a complete diagnostics 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-now 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.
The GFX4-IR is managed by a microprocessor that independently controls the four control loops and also runs functions specifically designed to manage singlephase and 3-phase loads, with low and high temperature coefficient, medium and short wave infrared lamps, and transformer primary circuits.
The multiple activation methods are all software-configurable, and include:
- Zero crossing with constant cycle time for conventional loads
- Burst firing with variable cycle time for systems with low thermal inertia, medium wave IR lamps
- Single cycle for short wave IR lamps with reduced flickering (half single cycle)
- Phase angle control with current limit for short wave IR lamps, transformer primaries, with assignment of soft start up and soft stop down options with limitation of max. rms current.
GFX4-IR runs complete diagnostics of current, voltage, and temperature levels:
Current:
- Total and partial interrupted load alarm
- “Teach-in” function for self-learning of alarm threshold for interrupted load
- SCR in short circuit alarm
- Load in short circuit or in overcurrent alarm
- Unbalanced 3-phase load alarm
Voltage:
- Phase loss in case of 3-phase configurations
- Check of correct phase sequence alarm
Temperature:
- Overtemperature alarm
Feedback functions:
Various feedback functions in the absence of PID control have been developed for complete control of loads in all types of applications:
- Voltage feedback (V) with current limit
- Current feedback (I)
- Power feedback with maximum power limit
Configuration is changed by setting simple parameters with a software tool that guides the user to a correct and safe configuration. GFX4-IR dialogs with the operator terminals according to the most popular protocols: from the simple and efficient Modbus to (via a second optional fieldbus communication) the by-now indispensable Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP, Ethernet IP.
The product comes with a standard configuration that is simple and quick to modify, for example, to assign different functions to outputs.
