*CLEMAP Load Management* supports external control signals, e.g. from the utility company.

·      via digital input (24VDC)

·      via the cloud via RestAPI interface

Supported modes are Normal, Reduced and Locked.

# Configuration 

The remote control signal is configured according to the image in the local user interface under *Device Config --> External Input Mapping* of the CLEMAP load management system.

**Remote control signal configured as normally closed** (default configuration in the CLEMAP Load Management system): The normal state is open, meaning that 0 VDC are present at the input. Once a signal comes from the energy provider, the relay closes, and 24 VDC are then present at the input.

| Limited to minimum           | The charging stations deliver the minimum permitted power                                              |
| Relative reduced limit (50%) | The charging stations deliver no more than 50% of their individual allocation                          |
| Reduced main limit (10–90%)  | The load management’s main current limit is reduced to the selected percentage of the configured limit |

# Display of Active Control Signal

Once the time tariff control signal is active and recognized by CLEMAP Load Management, it is displayed on the CLEMAP Floem platform.
