Setup
▪ Demand PCB (option EKRP1AHTA) needed.
▪ Maximum four digital inputs are used to activate the corresponding power
limitation level:
- DI1 = strongest limitation (lowest energy consumption)
- DI4 = weakest limitation (highest energy consumption)
▪ Specification of the digital inputs:
- DI1: S9S (limit 1)
- DI2: S8S (limit 2)
- DI3: S7S (limit 3)
- DI4: S6S (limit 4)
▪ Refer to the wiring diagram for more information.
Configuration
▪ Set the power consumption control settings in [9.9] via the user interface (for the
description of all settings, see
"Power consumption control" [
4
195]):
- Select limitation by digital inputs.
- Select the type of limitation (power in kW or current in A).
- Set the desired power limitation level corresponding to each digital input.
INFORMATION
In case more than 1 digital input is closed (at the same time), the digital input priority
is fixed: DI4 priority>…>DI1.
