The BTB controller has three running modes. To configure the running mode push the Shortcut button and select Running Modes.
| Mode | Description |
|---|---|
| AUTO | The controller automatically joins and splits the busbar. The operator cannot start a sequence manually. The controllers use the power management configuration to automatically select the power management action. |
| MANUAL | The controller cannot automatically join and split the busbar. The operator or an external signal can start these sequences. The controller automatically synchronises before closing a breaker, and automatically de-loads before opening a breaker. |
| BLOCK | The controller cannot start sequences. Select the block mode when you do maintenance work. |
