Danfoss gas detection Controller unit

Transcription

1 Data sheet Danfoss gas detection Controller unit The gas detection Controller Unit is used for a centralized monitoring and warning of hazardous gas concentrations. The input signals for the controller are collected from the local gas detection units of the types Basic, Premium and Heavy Duty via S85 Fieldbus or Analog communication. In total 96 gas detection sensors can be handled via Fieldbus + via Analog directly on the controller (+8 additional possible if expansion modules added). The Controller Unit comes with alarm relays available for external looped alarm devices. Additional relays and sensor wiring loops is possible by adding Expansion modules to the controller. Each local gas detection unit is assigned a unique address in the Controller and by continuous communication with the individual GDU s the Controller reacts on alarm signals from the local GDU. The parameter setting and the actual state of each local GDU can be read in the Controller display. Features For connection of up to 96 sensors via fieldbus + via Analog (when 7 expansion modules added) Easy configuration via intuitive user-interface; helps simplify operator handling and minimize risk of operational setting errors Simple commissioning by standard parameter configuration Flexible connection to local gas detection units by either Analog or S85 fieldbus communications Fieldbus wiring: Wire length up to 900 meters (95 ft.) per segment. relays for external alarm device circuits Up to 7 Expansion modules possible; allows additional 7 segments with a total of 700 meters (6 ft.) wiring and a total of relays for alarm device circuits. Automatic self-diagnostics to ensure correct communication and operation for communication error 6 menu languages Password protected settings allowing authorized access only Service alerts on display Conformity to EN Enables regulatory compliance with EN 78:06, ISO 59:0, AI758805en-0000 DKCI.PD.S00.G.0

5 Fieldbus loop Each GD controller can handle up to 96 sensors and handle any mix of individual Gas detection units of the types Basic, Premium and Heavy Duty. The max. recommended loop wire length is 900 meter (95 ft) per segment. With additional segments (and additional controller expansion modules) the max recommended loop wire length is 700 meter (6 ft). The controller and the last GDU in each segment must be provided with a resistor of 560 Ohm. A Umin of 6 V DC must be secured at any spot in the loop. Below figure shows how to make proper connections between the controller and each GDU.
