Control Requirements

EchoConnect

Echo interface devices require an ESD ground connection and EchoConnect,

which supporting control signal between the device and the connected Echo

control system. This connection is provided on a three-position terminal,

labeled EchoConnect, and accepts 0.2-4 mm2(24-12 AWG) wires.

EchoConnect is a bidirectional protocol that uses one pair of wires (data+

and data-) for both data and power. ETC recommends using Belden 8471 (or

approved equal) Class 2 wire. The total combined length of an EchoConnect

wire run (using Belden 8471, or equal) may not exceed 500m (1,640ft).

Electrical Requirements

Echo interface devices require 24 VDC (Class 2) external power in addition to

EchoConnect requirements. This auxiliary power is provided to the input

connector by an external supply. The unit draws a maximum of 40 mA during

normal operation. This connection is provided on a two position terminal,

labeled 24 VDC, and accepts 0.2-4 mm2(24-12 AWG) wires (typically black

and red wire pair).

Note:

NEC Class 2 product are to be wired in accordance with NEC

Article 725 and local jurisdiction requirements. All power and control

wiring should be installed and terminated by a qualified installer and

should follow standard wiring installation practices.

Contact and Demand Response Interfaces

Input and Demand Response Interface Wire Terminations

The Contact Input and Demand Response Interfaces provide four sets of

terminals (“In” and “V out”) for connection to a momentary (Input Interface

only) or maintained contact input. Terminals accept 0.2 mm2-4 mm2(24-12

AWG) wire. Each input supports wet or dry contact closures and includes a

related on board LED to indicate contact status.

Note:

Input terminals accept 3 - 24 VDC and support 610 m

(2,000ft) of 1mm2(18 AWG) wire (round trip wire to the device)

when using 24VDC.

Output Interface Wire Terminations

The Contact Output Interface provides four sets of terminals (normally open

“N.O.”, normally closed “N.C.”, and common “COM”) for connection of

output relays. Terminals accept 0.2 mm2-4 mm2(24-12 AWG) wire. Each

output includes a corresponding on board LED to indicate the normally open

status of the relay.

Set Configuration Mode

The configuration mode switch allows selection between Basic and Custom

configurations of the interface. Basic is the factory default setting.

Basic

Basic configuration mode applies the following default behaviors:

Input Interface:

Inputs control Presets 1-4 respectively, using momentary input mode where

the closure behaves similar to an Echo Inspire station.

•

close / open event (push) executes a preset toggle

•

holding the contact closed (hold) performs a space raise

•

closing the closure twice (in rapid succession) performs a preset toggle

with 1/2 second override timing

Note:

Use EchoAccess to assign a different Preset for the contact.

Note:

Particularly when considering machine driven applications,

ETC recommends a minimum of 500ms between any input changes

to ensure transitions are reliably applied.

Demand Response Interface:

Activates Demand Response, affecting up four consecutive Echo Spaces,

starting with the interface Space rotary switch setting.

Example: Example: Setting the Space switch to 3 results in control

of Spaces 3, 4, 5, and6. A value higher than 13 will result in control

of only Spaces 14, 15, and16.

Note:

Each Echo space can only have one assigned demand response

input.

Functionality:

•

a closed contact means the designated space is in active Demand

Response state

•

an open contact means Demand Response is inactive

Output Interface:

Relay outputs are controlled by Zones 1-4 respectively (when the Zone dial is

set to its default setting of 1). Changing the Zone dial will alter the starting

Zone. Reference the related note on

page 7

regarding zone ranges.

Contact and Demand Response Interfaces Page 5 of 8 ETC

ETC Installation Guide

Contact and Demand Response Interfaces

Note:

Functionality varies depending on whether the normally open

or normally closed contact terminal is utilized. The default behaviors

listed below are assuming a normally open installation. The normally

closed contact provides inverted behavior, its status always the

opposite of the normally open contact.

•

When the intensity of an assigned zone is non-zero the corresponding

relay output will be closed.

•

When the intensity of an assigned zone is equal to zero the

corresponding relay will be open.

•

By default, all odd numbered presets, when activated, will close all

relay outputs and all even numbered presets, when activated, will open

all relay outputs. This is true until the preset is recorded with the new

values.

Custom

Custom configuration mode applies the following default behaviors until

changed using the EchoAccess App:

Input Interface

Inputs control Presets 1-4 respectively, using maintained input mode where:

•

closing the contact activates the preset

•

opening the contact deactivates the preset

Demand Response Interface

Inputs control in spaces determined by settings applied in the EchoAccess

App.

Note:

Each Echo space can only have one assigned demand response

input.

Output Interface

Relay outputs are controlled by the status of Presets 1-4 respectively.

•

When the status of an assigned preset is active, the corresponding

relay output will be closed.

•

When the status of an assigned preset is inactive, the corresponding

relay will be open.

Aside from the default behaviors when the configuration mode switch set to

Custom, complete configuration of the Output Interface is supported by the

EchoAccess App. For detailed information about custom configuration

options available, reference the EchoAccess App integrated help system.

Contact and Demand Response Interfaces

Set Space and Address / Zone Start

Interface devices participate in an Echo control system using the configured

Space and Address / Zone which are selectable using the rotary switches on

the front of the unit. By default, these switches are set to Space 1, Address /

Zone 1.

1. Set the Space for this device (1 through 16 available). All control inputs

from the connected stations, sensors, and other controls are shared by

all devices within the selected space. This setting applies regardless of

the selected configuration mode (Basic or Custom).

Note:

For the Demand Response Interface, setting the Space address

determines the four consecutive spaces that will be controlled. A value

higher than 13 will result in control of only Spaces 14, 15, and 16.

2. Set the Address / Zone:

•

For a Contact Input Interface, set the Address (1 through 16

available) which identifies the device in the selected space. This

setting always applies.

Note:

Do not duplicate a device address within the same space.

•

For a Contact Output Interface, set the Zone number (1 through

16 available) for the first output on the interface. The remaining

outputs will be assigned consecutive zone numbers. The zone

number does not apply while in Custom configuration mode.

Note:

When setting the first zone number, be careful to allow

enough in the range for all outputs in the interface. For example, if

you set the first zone to address 15, the remaining output contacts on

the controller will be assigned to and respond as Zone 16.

Using a ball point pen, press the [Reset] button to reset the interface, cycling

power and restoring the device to normal operation.

Reset to Factory Defaults

Using a ball point pen, press the [Reset] button for ten seconds to reset the

interface to factory defaults. The power LED will flash when the device has

been restored to its factory defaults.

Remove the Interface from DIN rail

If for any reason you need to remove the unit from the DIN rail, follow these

instructions.

1. Shut power off from the unit and station power supplies on connected

EchoConnect segments.

2. Label, and then disconnect all wiring and cap off as necessary.

3. Insert a flatblade screwdriver into the clip on top of the enclosure, slide

it straight up, and then pivot the top of the unit off of the DIN rail.
