6.12.3 Analog Setpoint Signal
6.12.3.1 Connecting a Signal Source to an Analog Input for Active
Power Limitation
Analog signals for active power limitation are transmitted to the pin group Analog current input 2
in terminal X8 on the Cluster Controller. A remote terminal unit can be used as an analog signal
source, for example.
Additionally required material (not included in the scope of delivery):
☐ 1 analog signal source
☐ Connection cable (see Section 6.3 "Cable Requirements", page 30)
Requirements:
☐ The signal source must be technically suitable for connection to the analog inputs (see
Section 9, page 84).
☐ The connection cable must be prepared for connection to the multipole plug (see Section 6.5,
page 33).
