1. Function: The digital output function assigned to the terminals. The controller
software activates the function. For example: Breakers > [Breaker] >
Command > [*B] Close.
2. Coil: The controller energises the relay coil when the function is activated.
3. Normally open circuit: The normally open circuit closes when the coil is
energised.
4. Normally closed circuit: The normally closed circuit opens when the coil is
energised.
