Data sheet

Ground fault detector

Operating and environmental data

The ground fault detector monitors ground faults on the AS-Interface

lines and includes a self-test feature. The ground fault feature consists

of the LED 'Ground Fault (GF)', a 'Test/Reset' push-button and a relay

output. In case of failure, the output voltage will not switch off. For

proper functioning, it is essential to connect the shield terminal to PE

or machine ground. The AS-Interface network must not contain any

other ground fault detectors or insulation monitoring devices.

LED 'Ground Fault (GF)' displays a current or stored ground fault
