SYMEGA.
PRO
Grounding system
Symega grounding systems offer the best possible protection against electrostatic discharge during the process. Processes can be safely controlled or interrupted by continuously monitoring the resistance using grounding clamps and the potential-free changeover contacts connected to the monitoring system.
Application
The SYMEGA.PRO was developed for grounding when filling or emptying mobile containers such as tank trucks, IBCs, FIBCs, drums and etc. Grounding systems from the SYMEGA series are used in the chemical, food, pharmaceutical, cosmetics, oil and gas as well as wood industries.
Advantages
- One intelligent system for all applications.
- Capacity check of connected objects enables tamper protection.
- 24 VDC and 230 VAC power supply.
- Monitors the connection to the main ground.
- No loading fault due to loose contact.
- Safe grounding due to time limitation.
Mechanism
Electrostatic charges can build up as a result of the friction when flammable liquids, gases or solids are being loaded. The resulting electrostatic discharges (sparks) can be a risky ignition source for explosive atmospheres under the appropriate conditions. The SYMEGA.PRO continuously dissipates the electrostatic potentials to prevent these discharges. The grounding clamp is connected up to the object that has to be grounded (truck, drum, IBC, BigBags, etc.). If the SYMEGA.PRO detects the truck, the pumps, valves or mechanical conveyors connected to the grounding relay are activated for the filling process. The connection between the clamp and the object is permanently monitored. If a fault occurs or if the clamp’s connection becomes disconnected, then the grounding relay will generate a corresponding signal and the filling process will be stopped.
Extended range of functionality
- Timer functionIf a container filling or emptying process takes 10 minutes, for example, this period can be limited using the timer function. After the specified time, the SYMEGA.PRO is no longer enabled and the operator must reset and check the grounding connection. This prevents long-term bridging.
- Protection against loading faults due to loose contactIf the connection is briefly interrupted during truck grounding (capacity check on), the SYMEGA.PRO can bridge the time of the loose contact and keeps the release active. This allows loading to continue safely and the process does not have to be restarted.
- Monitoring the connection to the main groundThe SYMEGA.PRO can not only monitor the connection to the object to be grounded, but also to the main connection.
- All these functions can be customised via a menu on the device display.
More types
SYMEGA.SI
Grounding monitoring system
The SYMEGA.SI grounding system is installed in the switch cabinet outside potentially explosive atmospheres. It establishes a safe connection between stationary and mobile, metallic or conductive objects and good grounding. The circuits for grounding and the LEDs are intrinsically safe and may be routed up to zones 0 and 20 in order to visualise the current status of the grounding process in the application to the user.
SYMEGA.VO
Grounding monitoring system
Symega grounding monitoring systems offer the best possible protection against electrostatic discharge during the process. Processes can be safely controlled or interrupted by continuously monitoring the resistance using grounding clamps and the potential-free changeover contacts connected to the monitoring system.
