Early Ground Fault Detection
Increasing Availability via Improved and Preventive Maintenance
According to the IEC 60204-1 standard, measures must be taken to reduce the probability of malfunctions due to insulation faults/ground faults in a control circuit. A common option is connecting 0 V to the ground potential in the control circuit, in combination with an upstream fuse.
With the new ground resistance signaling module, WAGO offers the possibility of detecting not only the 0 V grounding, but also the full and automatic undershooting of a non-adjustable, unbalanced insulation resistance between +24 V or 0 V of the supply voltage and ground.
Early detection of imminent ground faults enables improved preventive maintenance, ensuring increased system uptime. A slide switch allows the user to select the grounded/ ungrounded control circuit operating mode. However, the module does not meet the requirements for insulation monitoring devices according to IEC 61557-8.
