Wiring guide: Beninca HEADY

This guide shows where each wire from the Nimbio terminal strip lands on the Beninca HEADY control unit. Gate Status: wired. Sense 1 and SC connect across the SCA contact (terminals 16-17), and Nimbio maps the relay’s two states to the labels shown in the app.

Before you start

Power the operator down at its supply before touching any terminal.
The Nimbio terminal strip has eight terminals: PWR+, PWR-, Sense 2, SC, Sense 1, NC, C and NO. This guide wires Sense 1 and SC; Sense 2 is not used (see “Connections”).
Power: PWR+ and PWR- land on terminals 14 and 15 (24 VAC accessory power, 500 mA maximum). The Nimbio board draws 40 to 70 mA.
You need a small screwdriver for the terminal screws.

Nimbio terminal strip (left) to the HEADY control unit (right). Wire tags name the destination terminal. On a phone, scroll the diagram sideways or pinch to zoom; the Connections list below has every wire.

When the wiring is done, restore power at the supply. A Nimbio support team member then calls to test the gate before you close the panel.

Settings on the operator

No operator setting is changed by this guide.

Gate Status

Gate Status: wired. Sense 1 (terminal 16) and SC (terminal 17) connect across the SCA contact. The contact is closed while the gate is open, pulses during movement, and is open while the gate is closed; Nimbio maps its states to the labels shown in the app. Sense-line polarity does not depend on the wiring. Nimbio maps each sense line’s triggered and untriggered state to an Open or Closed label after installation. If Gate Status shows the opposite of the physical gate, contact Nimbio support to have the labels switched; no rewiring is needed.

No suitable output on your operator? A magnetic gate switch can report the gate’s position instead: wire its two leads to Sense 1 and SC for fully closed, or to Sense 2 and SC for fully open. The switch must be a dry contact that puts out no power of its own; if yours puts out power, add a relay that turns it into a dry contact.
