Connecting terminals
You can connect limit switches, for example, via the terminals on the AS-i mounting module.
The following options are available to you:
●
3RA6970-3B: When the contacts open, the limit switch function immediately shuts down
the compact starter. The direct starter is shut down via terminals Y1 - Y2. In the case of
the reversing starter, direction of rotation 1 is shut down via terminals Y1 - Y2, and
direction of rotation 2 is shut down via terminals Y3 - Y4.
The safety function implemented by the shutdown must be tested by the plant operator at
suitable intervals in accordance with risk analysis. The installation environment must
meet the requirements of an IP54 environment. Suitable cabling and a suitable NC
contact must be used.
●
3RA6970-3C, -3D, -3E: The inputs and/or outputs can be switched as follows:
–
Inputs: floating switches (IN4, IN2)
–
Outputs: resistive loads (OUT2, OUT3)
●
3RA6970-3F: The local inputs Y1 - Y2 and Y3 - Y4 are used for switching from automatic
to manual mode and for manual control of the compact starter.
