RO-3 X - Relay Outputs and Supervision Contact
The Relay Outputs are potential-free contacts. In the Assignment/Relay Outputs section, the assignment of the Relay
Outputs is specified. The changeable signals are listed in the Assignment List section.
Make sure that the tightening torque is 5-7 In-lb [0.56-0.79 Nm].
Please carefully consider the current carrying capacity of the Relay Outputs.
Please refer to the Technical Data.
The
System-OK contact (SC relay)
cannot be configured. The system contact is a Form “C” contact that picks up when
the device is free from internal faults. While the device is booting up, the
System OK relay (SC)
remains dropped-off
(unenergized). As soon as the system is properly started (and protection is active), the System Contact picks up and
the assigned LED is activated accordingly (please refer to the Self Supervision chapter).
