Wiring guide: HySecurity SlideSmart DC

This guide shows where each wire from the Nimbio terminal strip lands on the HySecurity SlideSmart DC’s Smart DC Controller, and which relay function to program. Gate Status: wired. Sense 2 and SC connect to the controller’s USER RELAY 1, programmed to report the gate’s open limit, 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 2 and SC; Sense 1 is not used (see “Connections”).
Power: PWR+ lands on the Smart DC Controller’s 24VDC peripheral-power terminal (rated 1 A across four terminals) and PWR- lands on a COM terminal on the same strip. The Nimbio board draws 40 to 70 mA, well inside the 1 A budget.
You need a small screwdriver for the terminal screws.

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

USER RELAY 1 is programmed in the Installer Menu (RL 1) to function 3, “Open limit output,” so it closes when the gate reaches the open limit. Confirm the setting for your site with Nimbio support during installation.

Gate Status

Gate Status: wired. Sense 2 and SC connect to USER RELAY 1, an onboard relay set to report the gate’s open limit. The relay closes when the gate reaches the open limit, and Nimbio maps its two 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.

Frequently asked questions

Does the HySecurity SlideSmart DC need an expansion board for Gate Status? +

No. Sense 2 and SC land on the Smart DC Controller’s onboard USER RELAY 1.

Which Nimbio terminals open the gate on the HySecurity SlideSmart DC? +

NO and C, wired to RADIO OPEN and a COM terminal on the Smart DC Controller. The Nimbio relay closes NO to C, which the SlideSmart DC reads as a radio/remote open command.

Why is Sense 1 not used on the HySecurity SlideSmart DC? +

USER RELAY 1 is one relay with one state. Sense 2 and SC across it is the complete connection; a second sense line on the same relay would only mirror the first.

Is the Nimbio NC terminal used on the HySecurity SlideSmart DC? +

No. The operator input takes the NO and C pair, so NC stays empty.
