Configuring Time of Use and Digital Inputs

If needed, the configuration of time of use allows you to reduce the power capacity per zone at set periods of time to fit in with tariff policies.

To assign one or more periods to a zone:

1. Select ADMIN > Time of use.

2. Select the + sign to create a time-of-use period.

   

3. Enter a Period Name.

4. Define Timeslots:

   • Enter a Start Time.

   • Enter an End Time.

   • Select Add Timeslot to add another timeslot for this reduction.

5. Select the days when the timeslots apply.

6. Define a percentage for Maximum Setpoint.

7. Select Create.

8. Select ADMIN > Digital Input.

   NOTE: EcoStruxure EV Charging Expert digital inputs are accessible through GPIO connections located on the rear side of the EcoStruxure EV Charging Expert device. Activation of a digital input reduces maximum zone current according to its configuration.
   

   Electrical connection: only digital inputs 1, 2 and 3 are driven by GPIO channels 1, 2 and 3. To activate a digital input, it must be powered to 3.3 Vdc TTL.

   WARNING
   hazard of equipment damage Follow the wiring indications and the voltage of a maximum of 3.3 Vdc. Failure to follow these instructions can result in death, serious injury, or equipment damage.

9. Enable or disable digital inputs.

   NOTE: Each digital input can be enabled or disabled separately.

10. For each digital input, fill in the following fields:

    • Name

    • Maximum Setpoint: reduction in percentage applied to EcoStruxure EV Charging Expert zones

    

    For example, if you select 70, and if your actual setpoint for the charger is 32 A, the resulting setpoint applied to the charger is 32 A*70% = 22,4 A.
