The FAME 1 system
1. Operating plug for normal operation
2. Test plug for test operation
3. Test disconnect socket for wall and DIN rail mounting
4. Blind plug to cover the test disconnect socket
The switch contact in the test disconnect socket has been designed as an N/O contact. In normal operation, the operating plug closes the contact.
When the operating plug is inserted, the transformer short circuit is automatically overridden. The measuring transducer is operating safely.
If the plug is removed, the integrated switch contact automatically establishes a leading short circuit via the jumper used. Connected measuring transducers are safely protected against damage.
When inserting the test plug, the ammeter connected to the test plug is first of all looped into the circuit. Then the transformer short circuit is automatically overridden.
