The Gavita Master controller EL2 is compatible with all Gavita e-series

ballasts and fixtures.

3. Safety guidelines and measures

Warning! Keep the controller away from fire, excessive heat, water, dust and

contamination.

Warning! The Gavita Master controller EL2 may only be used to control

compatible Gavita e-series ballasts. Do not connect the controller to other

products as this may be dangerous and may cause malfunctions in the

connected equipment. Doing so will void the warranty.

Warning! The ECM channels of the Gavita Master controller EL2 may only be

connected to Gavita ECMs. Do not connect the controller to other products as

this may lead to malfunctions or damage and can be dangerous. Doing so will

void the warranty.

Warning! Do not open or disassemble the controller, it contains no

serviceable parts. Opening the controller will void its warranty.

Warning! Make sure the signal wires do not touch the reflectors. The

reflectors get very hot.

4. Installing the controller

4.1. Preparations

1. Mount the fixtures or ballasts as per your lighting plan. Interconnect them as

described in the manual of the fixture or ballast. Make sure the rotary knob

on all ballasts is set to “EXT” (external control). Connect the ballasts or

fixtures to the mains.

EXT

Each of the controller’s two channels can control up to 40 (250*) Gavita e-series

fixtures or ballasts. It is possible to use those channels to control fixtures in two

separate rooms, or to control up to 80 (500*) fixtures in one room. Channel 2 then

operates in “follow” mode.

* When using a repeater bus fixture or ballast. Check the specifications of your

fixture for more information.

Warning! The controller may only be connected to compatible Gavita e-series

remote ballasts and complete fixtures.

2. Find a suitable place for the temperature sensor and the controller. Hang the

sensor between the plants on average canopy height and preferably not

against the wall. Do not position it in direct airflow.

Average canopy height

Wall

Sensor

If you are using another climate control system, hang it close to the sensor of

that system. If necessary, the sensor cable may be lengthened an extra 5

meter with a standard 3.5 mm jack extension cable. A sensor with a cable

length of 30 meter is also available.

3. Cover the temperature sensor from the light. Use the hood supplied with the

controller and fold it around the sensor. Direct light cast upon the sensor will

disrupt temperature measurements.

4. Take the controller and remove the mounting plate from the body carefully.

Affix the mounting plate to a wall using the countersunk screws. Remount the

controller on the mounting plate.

5. If necessary, shorten the RJ cables. You’ll need an RJ crimp tool. Cut the

cables to the desired length. Strip 8mm of the outer insulation, but leave the

inner insulation intact. Push the four wires into the middle four openings of

the RJ plug. Crimp the plug on the wire with an RJ crimp tool.

6. Connect the lamp control cables to the controller. Connect the 4P4C end to

the controller, and the 6P6C end to the fixture. The lamps will not ignite yet.

7. Connect the power input and the temperature probes. The display will light

up, and you can continue to set up the controller.

4.2. Setting up the controller

1. The display lights up when the controller is connected to power. It will ask you

4.3. Connecting a temperature shutdown-, sensor failure- or

power-off alarm

Temperature shutdowns and power outages will always be logged. Access the log

by opening the menu and selecting logs.

The controller will remember its settings after a power outage. Time and date are

kept for approximately 40 hours. After this period, you’ll need to set this again.

The controller has two pairs of cage clamps marked A-NC (normally closed)

and A-NO (normally open). When a temperature shutdown, sensor failure

or power failure occurs the “A-NC” contact opens and the “A-NO” contact

closes. Both pairs of clamps may be connected to a third party alarm

installation or text messaging module.

Warning! The alarm contacts are rated for a maximum of 13,5V/50mA.

4.4. Connecting auxiliary equipment using the External

Contactor Module (ECM)

If you want to use the controller to control for example a CO source, a light

or watering unit, or a heater, you’ll need an External Contactor Module or

ECM. You can control up to two ECMs. ECM1 follows channel 1, ECM2 follows

channel 2.

ECM2 is inverse to ECM1 if channel 2 is set to follow or inverse mode.

Warning! Never connect more than one ECM to one set of cage clamps.

Warning! ECMs can handle equipment with a resistive load (AC1) of up to

16A. The maximum allowable current can be limited by the local situation.

Warning! To prevent over-current, always determine the maximum allowable

current for your cabling before connecting a load to the ECM.

1. Strip the endings of the signal cable 8mm. Finish them with cable end

sleeves. A cable of up to 20 meters may be used.

2. Press the spring pins above the contact openings of the cage clamps to open

them.

3. Insert the endings of the signal cable into the desired cage clamp set of the

controller.

4. Release the spring pins to lock the wires in place.

5. Connect the cable to the cage clamps of the ECM.

Consult the ECM manual to learn how to connect the ECM to auxiliary equipment.

4.5. Controlling auxiliary equipment

Auxiliary equipment can be activated either during lights-on period (day) or

lights-off (night).

1. Set the ECM for channel 1. Press enter to open the menu and select channel

2. Select ecm config.

5.6. Error messages and solutions

5.6.1. Sensor disconnected

The message “Sensor removed” appears when one or two temperature

sensors are not plugged in. All devices connected to the controller are

deactivated. Plug in the missing sensor to resolve.

5.6.2. Sensor failure

If the message “sensor failure” appears, the sensor is defect. All devices

connected to the controller are deactivated. The controller must be reset.

• Replace the temperature sensor

• Hold the back button for 3 seconds to reset the message.

5.6.3. Controller Overload

If the message “controller overload” appears, one of the channels of the

controller has been overloaded. The blue led indicator behind the overloaded

channel will also start flashing. An overload may occur when the wiring

of one of the channels has short circuited. All devices connected to the

controller will be deactivated.

• Check which channel indicates the overload.

• Search for faulty wiring or contacts and replace it.

• Hold the back button for 3 seconds to reset the message.

5.6.4. Auto-dim

When the auto-dim temperature has been exceeded, the message “auto dim”

will appear on the display next to the corresponding channel. The red light

will also flash. The flashing will continue until the temperature drops half a

degree Celsius/ 0.9 degrees Fahrenheit below the auto-dim temperature for

at least 30 seconds.

A burning red light indicates the auto-dim temperature has been exceeded

in the past.

• To resolve a burning red light, hold the back button for three seconds

to reset the warning.

5.6.5. Temp Alarm

When the shutdown temperature has been exceeded, the message “Temp

alarm” will appear on the display and the red light will flash rapidly. All
