A three-level terminal for a photoelectric sensor must represent three separate connection floors: two floors for the bridged positive and negative potentials and one unbridged floor for the signal. In EPLAN, define the floor for each terminal connection under the connection point designation properties. The available evidence does not prescribe which physical floor carries each function, so match the floor assignments to the selected terminal hardware and project wiring plan.
Define the Three Connection Floors
Insert the terminal connection, open its properties, and locate the Floor field under Connection point designation. Assign the appropriate floor to each of the three connection points so EPLAN can distinguish the stacked levels.
| Required circuit function | Floor assignment | Bridging requirement |
|---|---|---|
| Positive potential | Assign one hardware-matched floor | Bridged across the required terminals |
| Negative potential | Assign a different hardware-matched floor | Bridged across the required terminals |
| Sensor signal | Assign the remaining floor | Keep independent |
Configure Each Terminal Connection
- Insert the terminal connections required for the three-level device.
- Open the properties of each connection and navigate to Connection point designation.
- Set the Floor field so every connection corresponds to its physical level.
- Associate the positive, negative, and signal conductors with their intended floors according to the terminal manufacturer's arrangement.
- Represent bridging only on the positive and negative floors; do not bridge the signal floor.
Verify the Terminal Representation
Confirm that the three connections have distinct floor assignments and that the schematic agrees with the physical terminal. Check that the positive and negative potentials continue through their respective bridges while each sensor signal remains electrically separate. If the floor order is unavailable, obtain it from the selected terminal's product data before finalizing the assignment; the evidence does not establish a universal floor-to-function order.
Terminal Library Considerations
A manufacturer terminal library may contain a prepared three-level terminal article, which can reduce manual device-data entry. Library availability and exact article identifiers are not established by the evidence, so verify that any selected article matches the installed terminal and exposes the required connection floors.
FAQ
Where do I set the terminal floor in EPLAN?
Open the terminal connection properties and use the Floor field under Connection point designation.
How should a three-level photoelectric sensor terminal be represented?
Assign separate floors to positive, negative, and signal connections. Bridge the positive and negative floors as required, while keeping the signal floor independent.
Which terminal floor should carry positive, negative, and signal?
The evidence does not define a fixed floor order. Match each floor to the physical arrangement documented for the selected three-level terminal.
