Grounding Control Device EKX-4 (2-pole)
SPECIALIZED VERSION FOR CONTAINERS, IBCS AND BARRELS
The danger of electrostatic charges must always be observed when loading, unloading or handling bulk solids or inflammable liquids in the petrochemical, chemical, pharmaceutical, as well as in the food and feed industry. For application with containers, IBCs, barrels or trays, that may be insulated from ground potential, the EKX-4 (2-pole) is the Grounding Control Device to choose.
EKX-4 (2-pole) ensures that static electricity is safely discharged to the ground. It continuously monitors the electrical resistance of the grounding connection including the connection points at the grounding clamp. Only if the connected object is detected and grounded properly, the fi lling release will be signaled by green LEDs and the control outputs will switch. If there are any breaks in the grounding connection, the LEDs change to red and the fi lling will be interrupted immediately.
EKX-4 (2-pole) is mounted stationary, close to the loading/unloading gantry. It is used in gas and dust hazardous areas of zone 1 and 21 for objects to be grounded, that cannot be detected by the standard 1-pole Grounding Control Device EKX-4 such as containers, IBCs or barrels. Further areas of application are the grounding of materials handled with trays on conveyors in automated industrial processes.
■ Controlled low resistance grounding connection especially for containers, IBCs and barrels
■ Automatic diagnosis system continuously self-monitors all safety-related functions
■ Possibility to connect longer cables (up to 50 m)
■ NAMUR-compatible Ex i control output
■ Opening the housing under voltage is permissible - thanks to intelligent explosion protection (IEPC)
