4.6 Power supply
At ambient temperatures higher than +70°C or if thermal overloading occurs, the device is
not switched off. Instead, the output power is reduced sufficiently to protect the device.
Earth fault detection (EFD)
If an earth fault is detected in the AS-i system, it is evaluated by means of the EFD LED and
a floating switching output.
In the event of an earth fault, the LED lights up, the floating EFD output is opened and if the
switch is set to "EFD int." the device is switched off. Press the Reset button for at least two
seconds to restart it.
If the switch is set to "EFD ext.", the device continues to operate despite the earth fault.
By pressing the Reset button briefly (< 1 second), you can simulate an earth fault.
