| |
|
| Mode to by Internal Clock, you must also configure the schedule. Set the time when |
| |
|
|
| each tariff period starts, using the 24 hour clock format (00:00 to 23:59). The start |
|
|
|
| time of the next tariff is the end time of the current tariff. For example, T2 start |

|
|
| Select how the digital input functions: |
|
|
| Input Status | • Input status: the digital input records the status of the input, for example, OF, SD of |

|
| |
Digital Input | DI Function | Tariff Control | • Input Metering: the digital input is associated with input metering. The meter counts |
