Prepare for Installation

Inspect the Shipment
Before you begin installation, check your shipment and confirm that it arrived complete and undamaged.

1. Check the shipping box for physical damage.
   •  If you find damage, document it to help with a claim against your shipper.
2. Inspect the order for completeness.
   • Check the box contents received against the packing list to ensure your order received is complete.
   • If you discover a problem with the contents of the shipment, contact Echoflex Technical Services. See Help from Technical Services on page 4.

Main Circuit Breaker Protection

• Before beginning installation of your Room Controller–Gen 2, make sure you have installed a main circuit breaker cabinet or other readily accessible input power disconnect device.
• When more than one power source is supplying the Room Controller–Gen 2, a voltage barrier may be required by local code. This voltage divider is an accessory option, sold separately, and available for use when local code requires. Order Echoflex part number 7187K1000.

WARNING: RISK OF ELECTRIC SHOCK! Circuits that are installed without an accessible power disconnect device cannot be serviced or operated safely.

Installation Environment
Follow these guidelines for the installation environment:

• Intended for surface wall mounting or flush mounting (see Flush Mounting on the next page). The installation location and the mounting hardware must support at least 9 kg (20 lb).
• Install the enclosure in a location where it will not be subject to tampering or vandalism.
• For indoor use only! Operates at ambient temperature between 0°C–40°C (32°F–104°F), dry room 5%–90% non-condensing relative humidity.

Note: Always follow applicable building and local electrical code requirements when installing this equipment.

Flush Mounting

• Plan the mounting location such that the front edge of the back box will be coincident with the front of the drywall surface.
• Securely mount the Room Controller–Gen 2 to studs.
• Protect the Room Controller–Gen 2 appropriately during drywall mud application.

Tools and Supplies
The following tools and supplies are required for installation but are not included with the Room Controller.

Mounting hardware: four mounting bolts or screws
Note: Both the installation location and the mounting hardware must support a fully installed unit (including conduit and cable), which weighs approximately 9 kg (20 lb).

• Set of screwdrivers, including both flat-blade and Phillips-head types
• Conduit and supporting hardware
• Insulation stripping tool
• Appropriately sized wire nuts or WAGO® style installation connectors.
• Small 10–15 cm (4–6 in) cable ties

Conduit Access
Take care to separate high-voltage power from low-voltage (Class 2) control wiring. Use the knockouts on the top and bottom of the enclosure for conduit access into the unit. You can create additional conduit access using a knockout punch as needed.

• High-voltage wires : Left side (top or bottom) of the enclosure
• Low-voltage wires : Right side (top or bottom) of the enclosure
• Note: All low-voltage (Class 2) control cables must run in separate conduit from
• high-voltage power wires. To maintain the integrity of the voltage separation, use the provided voltage barrier inside the enclosure to separate all low-voltage components from the high-voltage power.

Electrical Input Wiring Requirements
Remove the main cover and the high-voltage cover to access the high-voltage electrical inputs, including input power and relay outputs, which are located on the left side of the enclosure. Note: Always follow applicable US National Electrical Code (NEC) and local electrical code requirements when installing and powering this equipment.

CAUTION: For your own safety, do not supply power to the enclosure until all installation is complete, connected circuits have been tested and found free of electrical shorts, and covers have been replaced. Follow appropriate Lockout/Tagout procedures as described in National Fire Protection Association (NFPA) Standard 70E.

Installation

Mount the Controller

1. Determine where your controller will be installed using the details outlined in Prepare for Installation on page 5.
2. Remove the front cover from the controller.
   • Surface mount : Loosen, but do not remove, the four screws securing the front cover. Slide the cover sideways, aligning the keyholes with screws, and then lift the cover off the enclosure.
   • Flush mount: Remove the four screws securing the front cover and set aside. Lift the cover off the enclosure.
3. Remove the two screws securing the high-voltage cover.
4. Lift the high-voltage cover off the enclosure using the provided lift pin.
5. Align the enclosure in the installation location and mark the mounting holes.
6. Remove the enclosure from the installation location and pre-drill the mounting holes.
7. Remove conduit knockouts or use knockout punch as required to accommodate control wiring. See Conduit Access on page 6.
8. Re-align the enclosure in the mounting location and install the mounting hardware. Tighten the mounting hardware securely.
9. Attach and tighten the conduit fittings to the enclosure.

Rough-In and Terminate Cable
All terminations are accessible from the front of the enclosure with the covers removed. The left side of the enclosure provides conduit entry for high-voltage wires and the right side provides conduit entry for low-voltage wires.

Note: Low-voltage control cables must run in separate conduit from input power wires. To maintain the integrity of the voltage separation inside the enclosure, a cover over the high-voltage terminations serves as a mechanical voltage barrier, separating the low-voltage power wiring from the high-voltage power inside the enclosure.

WARNING: RISK OF DEATH BY ELECTRIC SHOCK! Before installing input power, make sure the upstream source of power is off or isolated. Follow appropriate Lockout/Tagout procedures as described in NFPA Standard 70E.

CAUTION: Connecting to and configuring the Room Controller–Gen 2 requires contact with the printed circuit board inside the enclosure, which has electrostatic discharge (ESD) sensitive components on it. To avoid risk of damage to the equipment, ensure body static is discharged first by touching a grounded surface or wearing suitable ESD grounding equipment while terminating cables.

High-Voltage Wiring
High-voltage wire terminations are located on the left side of the enclosure, separated from the low-voltage terminations with a high-voltage cover. An additional voltage barrier (part number 7187K1000) is available for use to separate normal power and emergency power circuits or varying power inputs within the high-voltage wiring in the enclosure (as needed). The recommended cable for each termination is limited to the termination connectors provided in the Room Controller–Gen 2. See Electrical Input Wiring Requirements on page 7.

Sample Power Input and Relay Output Terminations
The following are sample termination scenarios for Room Controller–Gen 2 installations. Use these scenarios only as a reference, and refer to your electrician and wiring plans for your specific installation requirements.

Note: The In and Thru terminals are electrically connected on the circuit board.

Discrete Power for each Relay Output
In this typical installation scenario, power input would be provided from an upstream breaker panel, with one breaker for each relay plus one for the control power feed.

Bridging a Single Input Power Connection Across Relay Outputs

• In this installation scenario, a single input power connection (line, neutral, and ground) is bridged between the power input and all relays. Partial bridging, where multiple input power connections feed multiple output relays, is also acceptable.
• When bridging the input power, the total load is limited to 20 A across all connected relays.
• The control power feed is also bridged off of the input power connection (see dotted circle at left).

Bridging Relays with Normal/Emergency Power and Discrete Fed Breakers

• In this installation scenario, a single Normal/Emergency input power connection (line, neutral, and ground) is bridged between the control input (L) and one or more relay inputs (IN1 and IN2, using THRU1 and THRU2). Additional relays can be discretely fed from circuit breakers that are fed by other panels (IN3 and IN4).
• Because the input power is Normal/Emergency, a Normal sense circuit has been added to drive the Room Controller–Gen 2 to its emergency control configuration on loss of normal power (N_SENSE and L_SENSE). This circuit does not feed a load from the Room Controller–Gen 2, nor does it provide power to the controller.
• Voltage barriers (part number 7187K1000) are available and sold separately for separating between mixed voltage or normal and emergency loads.
• When bridging the input power, the total load is limited to 20 A across all connected relays.

Note: If any emergency circuits are fed or controlled from this panel, the panel must be located electrically where fed from a UPS, generator, or other guaranteed source of power during emergency and power outage situations.

Note: Voltage barriers between normal circuits with different voltage inputs are only required if the wiring used for 120 V circuits is not rated for 277 V.

Terminate Input Power and Relay Outputs

1. Terminate control input power (as shown in Discrete Power for each Relay Output on page 11) or control input power and sense circuit, if used (as shown in Bridging Relays with Normal/Emergency Power and Discrete Fed Breakers on the previous page).
2. Pull input power (2 wires plus ground) to the left side of the enclosure.
3. Strip 12 mm (1/2 in) of insulation from each wire.
4. Insert the ground wire into the ground terminal (labeled with a ground symbol), and torque the terminal to 1.76 N·m (1.3 foot-pounds).
5. Insert the line (hot) wire into the L terminal and torque the terminal to 1.76 N·m (1.3 foot-pounds).
6. Insert the neutral wire into the N terminal and torque the terminal to 1.76 N·m (1.3 foot-pounds).
7. Insert the optional sense circuit line and neutral wires into the N_SENSE and L_SENSE terminals, and torque the terminals to 1.76 N·m (1.3 foot-pounds).
8. If bridging control input power to a relay, insert a wire between the L terminal and the IN* (IN1, IN2, etc.) of the desired relay. See step 2d (below) to bridge subsequent relays to control input power.
9. Terminate relay outputs (4 or 8 relays).
10. Pull relay output wires (2 to 3 wires for each relay depending on the installation requirements) to the left side of the enclosure.
11. Strip 12 mm (1/2 in) of insulation from each wire.
12. Insert the line (hot) wire to the terminal marked IN* (IN2, IN3, etc.) and torque the terminal to 1.76 N·m (1.3 foot-pounds).
13. When bridging relay outputs, insert a wire between the THRU terminal and the next relay IN terminal. If you are not bridging outputs, do not terminate to the THRU terminal.
14. Connect the load wire to the terminal marked OUT* (OUT2, OUT3, etc.) and torque the terminal to 1.76 N·m (1.3 foot-pounds).
15. Install a relay voltage barrier between any normal power relays and emergency power relays in the enclosure, or between relays with different voltage inputs. Relay voltage barriers are available for purchase from Echoflex. Order part number 7187K1000.

Low-Voltage Wiring
Low-voltage wire terminations are located on the right side of the enclosure, visible with the front cover removed.

About Contact Inputs
Contact inputs are available for:

• Demand Response Input : Accepts a remote trigger that allows the controller to reduce lighting levels, thereby reducing power consumption.
• UL 924 Input : Used to trigger emergency lighting control bypass from a system such as a fire alarm.
• Contact Input: Used to trigger a preset, sequence, or other event from an external system, such as an AV control system.

The contact inputs can be configured as follows:

• Demand Response input requires a normally open dry contact closure.
• UL 924 input is configurable to be a normally open or normally closed contact, and requires a maintained dry contact closure.
• Contact Input is configurable to be a momentary (default) or maintained contact, and requires a normally open dry contact closure.

Configuration switches are available for the Emergency (UL 924) Input and Contact Input to further define normally closed (maintained) configuration as needed. Demand Response contacts are always normally open and are not provided with additional configuration options.

Note: Each Elaho Space can have only one assigned Demand Response input.

Terminate Contact Inputs
Dry contact input terminations are the same regardless of function.

1. Pull 2 wires to the right side of the enclosure.
2. Strip 6 mm (1/4 in) of insulation from each wire.
3. Insert one wire into each terminal for the contact input, and torque the terminal to 0.5 N·m (4.4 inch-pounds).

Terminate 0–10 V Outputs

WARNING: RISK OF DEATH OR INJURY BY ELECTRIC SHOCK! 0–10 V wiring may not be fully isolated from high-voltage AC power. Do not assume that 0–10 V wiring is safe to touch, even when run as an NEC Class 2 signal. Test for AC voltage to ground before terminating any 0–10 V control wiring to the device.

CAUTION: Only ballasts and drivers with isolating transformers are recommended for use with the Room Controller–Gen 2.

The Room Controller–Gen 2 offers fully isolated 0–10 V output control for each zone, allowing direct connection to dimming ballasts and LED drivers. The 0–10 V outputs are capable of sinking a current of up to 100 mA.

1. Pull 0–10 V wiring, typically a gray and violet wire pair, to the right side of the enclosure.

• Strip 6 mm (1/4 in) of insulation from each wire.
• Insert the positive wire (typically violet) into the terminal labeled “+” and torque the terminal to 0.5 N·m (4.4 inch-pounds).
• Insert the negative wire (typically gray) into the terminal labeled “-” and torque the terminal to 0.5 N·m (4.4 inch-pounds).

Terminate the EchoConnect Bus

• The Room Controller–Gen 2 connects to the EchoConnect station communication bus, and provides data and power for up to six Elaho control products (stations and sensors) and up to five additional Elaho output products when the related Station Power Supply Switch is enabled.
• EchoConnect is a bidirectional protocol that uses one pair of wires (station + and station -) for both data and power. Because EchoConnect is topology free, you can install the wires in any combination of bus, star, loop, or home-run.
• Use Belden 8471 (or equivalent) Class 2 wire to terminate the EchoConnect bus. Termination for EchoConnect and the 24 VDC output power (for Elaho TimeClock) is a shared connector on the low-voltage side of the enclosure.
• For Room Controller–Gen 2 models that include a built-in Elaho TimeClock, a pigtail wire harness is installed to the EchoConnect bus connector, and provides pluggable connectors to the TimeClock interface for both EchoConnect and 24 VDC.

Note: By factory default, the Station Power Supply switch is disabled. Only one power supply per EchoConnect station bus should be enabled. If more than one power supply is enabled, Elaho devices will not function correctly.

Note: All control wiring should be installed and terminated by a qualified installer and should follow standard wiring installation practices. Leave approximately 25.4 cm (10 in) of wiring in the back box for connection and to allow slack for future service needs.

Note: Echoflex requires that all stations and devices be grounded for ESD protection. Pull an additional 2.5 mm2 (14 AWG) wire for grounding when control wires are not installed in grounded metal conduit.

1. Pull the required wiring (station +, station -, and ESD ground wire) to the right side of the enclosure.
2.  Terminate the incoming ground wire to the terminal labeled with a ground symbol ( ) and torque the terminal to 0.5 N·m (4.4 inch-pounds).
3. Terminate the station + wire (typically white) to the terminal labeled STN+ and torque the terminal to 0.5 N·m (4.4 inch-pounds).
4. Terminate the station – wire (typically black) to the terminal labeled STN- and torque the terminal to 0.5 N·m (4.4 inch-pounds).

Terminate 24 VDC Power
The Room Controller–Gen 2 provides 24 VDC power out for an Elaho TimeClock (optional). This termination point is shared with the EchoConnect bus connector, located on the low-voltage side of the enclosure (see image on page 16).

Note: The Room Controller–Gen 2 provides 24 VDC auxiliary power only for an Elaho TimeClock. For Elaho products other than the Elaho TimeClock, order an external Elaho Power Supply with 24 VDC auxiliary power. Request part number 8186A1212.

• For Room Controller–Gen 2 models that include a built-in Elaho TimeClock, a pigtail wire harness is installed to the EchoConnect bus connector and provides pluggable connectors to the TimeClock interface for both EchoConnect and 24 VDC.
• If you are using an Elaho TimeClock as an external device, Echoflex recommends the use of 16 AWG (1.5 mm2) wires, typically black-and-red wire pair, to terminate between the TimeClock and the Room Controller–Gen 2 24 VDC terminals.

1. Pull the required wiring (+ and -) to the right side of the enclosure.
2. Terminate the negative (typically black) wire to the terminal labeled COM and torque the terminal to 0.5 N·m (4.4 inch-pounds).
3. Terminate the positive (typically red) wire to the terminal labeled 24 V and torque the terminal to 0.5 N·m (4.4 inch-pounds).

Configure the Room Controller–Gen 2

Set the Space and Zone Switches

• Assign Space and Zone addresses using the two rotary switches, which are located on the low-voltage side of the controller. By default, these switches are set to Space 1, Zone 1.
• When you select the Space, all control inputs from the connected stations, sensors, and other controls are shared by all devices within the selected space.
• The Zone switch sets the zone for the first output in the controller, and automatically assigns the next consecutive zone numbers to the remaining outputs in the controller. For example, if you set the Zone switch to 12 on a 4-relay controller, the controlled zones are 12, 13, 14, and 15.

Note: When setting the first Zone address, be careful to allow sufficient range for all outputs in the controller. For example, if you set the first Zone address in an 8-relay controller to 10, the last two outputs in the controller will be assigned to and controlled by 16.

1. Set the Space rotary switch to the desired Space for this controller.
2. Set the Zone rotary switch to the desired Zone for this controller.

Set the Contact Input Configuration Switch
The Contact Input configuration switch provides selection of the contact input configuration, either Momentary (default) or Maintained, for the contact input.

• In Momentary mode, closure of the contact toggles the configured Preset.
  • If the Preset is inactive and the contact is closed, it activates the Preset.
  •  If the Preset is active and the contact is closed, it deactivates the Preset.
• In Maintained mode, closure of the contact activates the Preset or plays the Off action configured for contact closure. Opening of the closure activates the Preset or Off action configured for the contact opening.

Note: Default settings for Contact Input configuration:

• Maintained mode: Play Preset 1 (opened), Preset 4 (closed)
• Momentary mode: Toggle Preset 4 on and off

Set the Station Power Switch

• A system of Elaho products can consist of up to 16 Elaho power controllers and 16 Elaho devices (stations and sensors). The Room Controller–Gen 2 is considered a power controller. A Room Controller–Gen 2 with a built-in Elaho TimeClock is considered both a power controller and a station.
• The Room Controller–Gen 2 can provide EchoConnect bus power supporting an Elaho system with up to 6 Elaho devices (stations and sensors), and up to 6 power controllers when the Station Power switch is enabled (set to On). By factory default, the Station Power switch is disabled. An external power supply is required to support a full system maximum of 16 Elaho devices.
• To enable the EchoConnect bus power supply from the Room Controller–Gen 2, slide the Station Power switch to the “On” position.

Note: Enable only one EchoConnect power supply per station bus. If more than one power supply is present, Elaho devices will not function correctly.

Set the Sense Enable Switch

• Set the Sense Enable switch to On if your installation uses the optional sense circuit (see image above). The default setting is Off.
• When Sense Enable is set to On, the Room Controller–Gen 2 will trigger the UL 924 emergency lighting control bypass when power to the normal sense is absent. See Electrical
• Input Wiring Requirements on page 7 and Bridging Relays with Normal/Emergency Power and Discrete Fed Breakers on page 12.

Set the Emergency UL 924 Configuration Switch
To configure the UL 924 contact input, set the Emergency UL 924 Configuration switch to one of the following options:

• NO (normally open [default])
• NC (normally closed)
• Off (disabled)

Set the Emergency UL 924 Load Shed Switch

• The Emergency UL 924 Load Shed switch provides configuration to enable or disable load shedding when an emergency contact input is activated (opened or closed depending on the state of the Emergency UL 924 Configuration switch). By factory default, this switch is set to On (enabled).
• Load shedding functions in conjunction with the Emergency UL 924 Inclusion switch for each output (see Set the
• Emergency UL 924 Inclusion Switches below). The table below describes what occurs when the emergency contact input is activated.

UL 924 Load Shedding

maximum output level.
No| On| Load and its connected 0–10 V output will be turned off.
No| Off| Load remains at its current level.

Set the Emergency UL 924 Inclusion Switches
Each output in the Room Controller–Gen 2 has an Emergency UL 924 Inclusion Switch that configures the circuit to be included or excluded from the Emergency UL 924 configuration. By factory default, all outputs are set to On (included) in Emergency.

• An output that is included in Emergency (switch is set to On) will turn the load on to full when the Emergency contact input is activated.
• An output that is excluded from Emergency (switch is set to Off) will behave according to the UL 924 Load Shed configuration switch. See Set the Emergency UL 924 Load Shed Switch above.

Set the Demand Response Levels

• When closed, the Demand Response contact input limits the maximum 0–10 V level of each zone (output) to the configured level that was set using the Demand Response rotary fader corresponding to each zone.
• Use a precision screwdriver to change the rotary fader level to any value between 0%–100%. A Demand
• Response rotary fader setting of 0 turns the relay off when Demand Response is triggered. The Demand Response rotary faders are set to 50% as a default.

Power Up and Configure

Before Applying Power to the Room Controller–Gen 2

WARNING: RISK OF ELECTRIC SHOCK! Power must be off when you perform this procedure.

CAUTION: Checking the Room Controller–Gen 2 installation requires contact with the printed circuit board inside the enclosure, which has electrostatic discharge (ESD) sensitive components on it. To avoid risk of damage to the equipment, ensure that body static is discharged first by touching a grounded surface or wearing suitable ESD grounding equipment while terminating cables.

1. Clean out dust, metal scraps, or other debris from the enclosure.

2. Check for loose connections, bare wires, or damaged insulation on both the low-voltage and high-voltage sides of the enclosure.

3. Replace the high-voltage cover to the unit and secure with screws.

4. Check that all configuration switches are set according to the installation requirement. See Configure the Room Controller–Gen 2 on page 17.

Use a voltage meter to check power between the STN- and STN+ terminals on the EchoConnect station connector. If any voltage is present, disable or leave the Station Power Supply Switch in the Off position. See Set the Station Power Switch on page 18.

Note: Only one power supply per EchoConnect station bus should be enabled. If more than one power supply is enabled, Elaho devices will not function correctly.

Power Up and Check Features

1. Apply power at the breaker that supplies power to the electronics.
   WARNING: RISK OF ELECTRIC SHOCK! Mains voltage is present inside the high-voltage compartment of the enclosure. Do not remove the high-voltage cover when power is applied.

2. Locate the status LEDs on the low-voltage side of the enclosure.

   • POWER: Indicates blue when power is present.
   • DMND RESP: Indicates green when the Demand Response input is closed.
   • EMERG: Indicates red when the UL 924 contact input is closed or when the normal sense loses power.
   • CONTACT IN: Indicates green when contact input contact is closed.
   • STATION POWER: Indicates green when EchoConnect bus power is present and blinks with activity on the EchoConnect station bus.

3.  Test each contact input to ensure that it functions as expected. With contact activity, the configured relays should respond and the status LEDs should indicate. See Configure the Room Controller–Gen 2 on page 17 as needed for further configuration.

4. For a Room Controller–Gen 2 that includes a built-in TimeClock, install the connectors from the pigtail wire harness to the rear of the TimeClock. See Terminate the
   EchoConnect Bus on page 16.

5. Replace the main cover on the unit and secure the screws firmly.

Emergency Circuits Label
The Elaho Room Controller–Gen 2 ships with an “EMERGENCY CIRCUITS” label for application only to equipment connected to circuits designated for emergency power, in accordance with NEC Article 700 or an equivalent applicable installation code.

• If the Room Controller–Gen 2 will be connected to circuits designated for emergency power, apply the “EMERGENCY CIRCUITS” label to the main product label as shown at right.
• The “EMERGENCY CIRCUITS” label must be applied to the equipment in a location that will be visible after installation.

Preset and Zone Configuration
The Room Controller–Gen 2 supports either 4 or 8 zones, depending on the model, and up to 16 built-in presets.

Preset Defaults
Preset levels for all controllable outputs default to the following values:

Fade time defaults are 2 seconds for 0–10 V outputs and switched relay outputs. You can configure the fade time using the ElahoAccess Mobile App. See the ElahoAccess integrated help system for details about available configurable device parameters and actions.

Contact Input Preset
The Contact Input is configurable to be a momentary or maintained contact closure and requires a normally-open dry contact closure.

Note: Default settings for Contact Input configuration:

• Maintained mode: Play Preset 1 (opened), Preset 4 (closed)
• Momentary mode: Toggle Preset 4 on and off

Custom Configuration Options

• By default the configuration switch is set to Custom which allows custom configuration options for the controller using the ElahoAccess Mobile App. For more information about the custom configuration options see the ElahoAccess integrated help system.
• Alternatively, set the switch to Basic for default functionality.

TimeClock Configuration
See the Elaho Astronomical TimeClock Configuration Manual for instructions on configuring the Elaho TimeClock.

Demand Response

• When Demand Response is active, check that the outputs are at the expected level.
• If the observed output level is different than expected, check the Demand Response LED for indication of activation. See Power Up and Check Features on page 23 for LED indications.
• The outputs generated with an active Demand Response will not exceed the level set by each of the corresponding Demand Response rotary faders. See Set the Demand Response Levels on page 21.

Troubleshooting

Reboot the Room Controller–Gen 2
As a first step in troubleshooting, you may want to reboot the Room Controller–Gen 2. Press and release the [Reset] button to reboot the Room Controller–Gen 2.

Restore Factory Defaults

1. With power applied to the unit, set both the Space and Zone rotary switches to 16.
2. Press and hold the [Reset] button for approximately 10 seconds:
   • The Room Controller–Gen 2 erases all customer stored Preset data and restores to factory default values.
   • The DMND RESP, EMERG, CONTACT IN, and STATION POWER LEDs blink slowly to indicate that the defaults have been restored.
   • The Room Controller–Gen 2 reboots.
3. To continue the configuration of your Room Controller–Gen 2, reset the Space and Zone rotary switches to the correct values before proceeding.

Update Firmware
If updated firmware is required, you can update the firmware on the Room Controller–Gen 2 by using ETC UpdaterAtor software and a microSD card. You can download UpdaterAtor from the ETC website at etcconnect.com.

Note: Plan to update firmware when troubleshooting any issues with the Room Controller–Gen 2.

1. Get the firmware update file using UpdaterAtor.

2. Save the firmware update file to the root directory of a microSD card.

3. Insert the microSD card in the SD slot on the low-voltage side of the enclosure (see image at right).

4. Press the [Reset] button at the top of the low-voltage side of the enclosure.
   The POWER LED at the bottom of the enclosure will illuminate blue in a three- blink pattern while the firmware is updating, and then will return to its previous state when the update is complete. If the EMERG LED illuminates red in a two-blink pattern, an error has occurred. Ensure that the firmware file has not been renamed and is located at the root directory on the microSD card, and then attempt the firmware update again. If the LED continues the two-blink pattern, contact Echoflex Technical Services (see Help from Technical Services on page 4).

5. When the LED returns to its previous state, remove the microSD card.
