Toggle/Local Override/Channel Control Buttons

On output units (e.g., DIN-rail Dimmers and Relays), these buttons operate a unit’s

output channels and LEDs, as long as the unit is connected to line voltage. Use

them to verify that the power lines are installed correctly and that each channel

switches the correct load(s). These buttons are multi-functional.

Override Button Functions

The Toggle’s Status Indicator LED shows the status (ON or OFF) of each channel on

that output unit.

Light ON/lit, the channel is ON; light OFF/unlit, the channel is OFF.1.

A press on a Toggle/Local Override/Channel Control button manually overrides 2.

the current state of that channel.

Local Override/Channel Control buttons can be used to start Learn Mode and 3.

Override Button Operations

When one or more channels or units are in Local Override mode, different button

presses have different effects.

Short press: “Toggles” that channel/unit, e.g., from OFF to ON.•

Double press: Returns control of that channel/unit to the C-Bus network.•

Long press: All channels or units in Local Override mode are returned to control •

by the C-Bus network.

VERIFYING NETWORK POWER

The amount of current required for a C-Bus network depends on the current drawn

by its C-Bus units. Typical C-Bus units draw 18–40 mA, and many networks require

less than 2 A. See a unit’s illustration or installation bulletin to determine its current

requirements. The steps below summarize how to calculate a network’s power

requirements and verify that only 2 A will be supplied to the network. (The C-Bus

Toolkit software will also calculate this for you.)

STEP 1: Add up the current consumed by all the input, system support, and output

units that draw power from the C-Bus network. Remember that the combined

current consumed by all these units must not exceed 2 A.

Unit Type No.
