4 Using the RLED 2.0

The following sections detail how to use the RLED 2.0. After setting the parameters, RLED 2.0 automatically backs them up. In cases when the power shuts down and goes back on, the controller continues operating as in its last saved state.

• Preliminary Setup Options
• Bright Mode
• Manual Dim Mode
• Auto Mode
• Performing a Cold Start

Preliminary Setup Options

Press Options of either channel for three seconds to enter the system parameters menu. The first parameter is “bu”. To navigate to the other parameters, press the Options button. The sequence order of parameters to appear is as follows: bu > Ch > Pu > br > Cn.
NOTE The “Options” button is also used to exit from this menu.

• System Parameter 1 – Minimum Light Calibration (bu)
• system Parameter 2 – Line Channel (ch)
• System Parameter 3 – Ignition Pulse (Pu)
• System Parameter 4 – Brightness Restriction (Br)
• System Parameter 5 – Curve (Cn)

SYSTEM PARAMETER 1 – MINIMUM LIGHT CALIBRATION (BU)

To use the RLED 2.0 with a light bulb, the user needs to configure the RLED 2.0 to work with that specific bulb. RLED 2.0 enables working with most light bulbs because the user is able to define that bulb’s minimum lighting level. The bu parameter defines this parameter. RLED 2.0 defines the level chosen as being 1% of the maximum light level. Any function based on the light level uses this parameter as the basis for any calculation.
RLED 2.0 must be installed and connected to the LEDs.
To calibrate the 1% level:

1. Press Options for three seconds. Bu and a number (the pulse width in microseconds) appear.
2. Begin pressing the Up/Down arrow.
   • Pressing the Up arrow causes the number to change by five points.
   • Pressing and holding down the Down arrow causes the number to change by five points.
   • Pressing and quickly releasing the Down arrow causes the number to change by one point.
3. Keep pressing until the light reaches the approximate minimum brightness that you require.
4. Press the Down arrow to fine tune the brightness.

NOTE Munters recommends calibrating the light level every time you install bulbs, in particular if you install LED lights from a different manufacturer.

SYSTEM PARAMETER 2 – ADDRESS (AD)

The “Ad” (address) parameter sets the connection address. The parameter is used to accurately configure communication between the RLED 2.0 and the controllers.

• 0 represents connection via voltage-controlled mode using 0-10 VDC analog input
• 1-8 represents connection channels via the controller’s communication feature.

1. Press Options for three seconds.
2. Go to ch.
3. Select the connection mode.
   • Connecting via the controller’s communication feature: Set the parameter from 1 – 8. Refer to Configuring the Channel Levels, page 14 for further details regarding numbering.
     NOTE The unit must be set to Auto Mode when working with a controller (refer to Auto Mode, page 10).

SYSTEM PARAMETER 3 – IGNITION PULSE (PU)

This parameter defines a short burst of electricity sent to the lights when the lights go from off to 1%. The lights will shine briefly and then return to the minimum light level.

1. Press Options for three seconds.
2. Go to Pu.
3. Chose the brightness level:
   • Level 0: No pulse ignition
   • Levels 1 (lowest) to 9 (highest)

SYSTEM PARAMETER 4 – BRIGHTNESS RESTRICTION (BR)

This parameter restricts the maximal value of brightness according to the user’s setting. The default value is “On” (100%). Adjust the desired limit through use of the “UP” and “DOWN” buttons. This feature is useful when there is no need for the maximal brightness and helps to save power.

1. Press Options for three seconds.
2. Go to br.
3. Using the arrow keys, define the restriction level.

SYSTEM PARAMETER 5 – CURVE (CN)

NOTE Munters recommends leaving this parameter at the default setting. Change the setting only if the lights flicker.
To define the curve:

1. Press Options for three seconds.
2. Go to Cn.
3. Choose (2) (default setting) or (1).
   NOTE After changing the curve, recalibrate the Minimum Light Calibration.

Bright Mode

The Bright mode raises the light intensity to the maximum value set in the “br” parameter. The light remains at this level for 20 minutes. The feature is useful, for example, when a farmer needs to have the light on for a specific period of time in the poultry house. After that time period, the light dims gradually down to the previous value.
After turning on the lights, press the arrow buttons to increase or decrease the time that the lights remain on.
NOTE The system returns to the previous mode, at the point where it left off. To keep the brightness at this level, set the unit to Manual Dim Mode.

Manual Dim Mode

Pressing “Manual Dim” enters the device into “Manual Dim” mode. The display changes and indicates the voltage percentage value for that channel. Manual Dim is used to override the Auto Mode settings.
In manual mode the user changes the light brightness by pressing the UP and DOWN arrow keys.

Auto Mode

Pressing the “Auto” button enables connecting the RLED 2.0 to a controller. There are two ways to connect the RLED 2.0 to a controller:

• Via an analog output card 0-10 VDC (All Munters Controllers)

• Via a communication card (Platinum Pro Controllers only)
  CAUTION Connect the RLED 2.0 to a controller using one option only! Connecting the RLED 2.0 using both methods together results in faulty light levels.

• Refer to System Parameter 2 – Address (Ad), page 9 to define the controller connection.

• Refer to Configuring the Channel Levels, page 14 for information of connecting the unit to a controller.

Performing a Cold Start
Run a Cold Start to return the RLED 2.0 to its default parameters:

1. Press the Channel A arrow buttons and the internal reset button (located on the CPU card).
2. Release the reset button.
   Cold appears on the screen.
   NOTE To check the software version, press the RESET button.

Configuring the Channel Levels

The following sections detail how to configure the channel levels.

• Using an Analog Output Card
• Using a Communication Card

USING AN ANALOG OUTPUT CARD

NOTE Verify that parameter “Ad” is set to “0” (refer to System Parameter 2 – Address (Ad), page 9).

1. Connect the 0 – 10 VDC (+) and COM (–) wires from the external device to terminal ports “0 10V A”, “0-10V B” and COM (Figure 6).
2. To control both channels simultaneously, short “0-10V A” and “0-10V B”.
3. To configure the channel levels go to the:
   • Analog output table (Farm Premium, Platinum Pro and Super Guard)
   • System parameters (AC-2000)

USING A COMMUNICATION CARD

1. Lift the top board.

2. On the board are four dipswitches. Set the dipswitches to the required setting.

3. Connect the RLED 2.0 to a Platinum Pro communication card.NOTE Verify that parameter “ch” is set to “1 – 8” (refer to System Parameter 2 – Address (Ad), page 9).

4. Configure the channels. There are two numbering options:

   • Different numbers to each channel, with up to eight different channels (when using multiple RLED 2.0 units).

   • Same number for more than one channel if you require the same behaviors from these channels.
     For example, two RLED 2.0 units can control four channels using the communication line:

   • 1st channel (A1) #1: 20%

   • 2nd channel (A2) #2: 10%

   • 3rd channel (B1) #2: 10% (same as A2)

   • 4th channel (B2) #3: 90%
