Abbreviations and Terms

status of various functions on the front panel.
Default| A value permanently stored in memory and is used to define the parameter in the absence of a user-defined value.
Restart| The procedure that aimed to renew the device state.
Cold Start| The procedure that restores default (factory) values of the parameters
“bu”| Bulb : This parameter defines the bulb type (Incandescent, LED, fluorescent, cold cathode)
“ch”| Channel : This parameter can receive values between 0 – 8 since it can be connected to eight matching lines of the Platinum / AC-2000 controller.
“Lo”| Low : This parameter prevents lamps from burning out through defining a minimum brightness limit. This value cannot be higher
“br”| Brightness Restriction : By this parameter one can restrict the upper limit of the output voltage. It’s values can be within “On” (100) and “0” (0%)

User interface

The following section details the keypad.

Figure 1: Front Panel

Note that the keypad is divided into two channels (‘A’ and ‘B’), press the appropriate channel buttons. The relevant LED indicates the current active mode

1. Cursor keys : These keys change values of output voltage (in percentage)

2. Channels : This specifies which channel is being dealt with. Note that the buttons are duplicated since each one is dedicated to each channel separately.

3. Display : Both values of voltage and parameters are displayed here.

4. Manual Dim : Pressing this button sets the RLD channel to manual mode. In manual mode you can set the light percentage using the arrow keys. Verify that you are changing the required channel.

5. Bright : Pressing this button gradually increases the channel to full  brightness for a period of 20 minutes. Adjust the time period by pressing the up/down cursor keys. The display shows the remaining amount of time before the light begins to turn off. When this period ends, the decrease in light is gradual.

6. Auto: Pressing this button utilizes the analog input card 0-10 V output or communication card and is controlled via a lighting table program.

7. Off: Pressing this button gradually reduces the channel to 0% light intensity.
   NOTE The lights go off at the Lo setting.

8. Options: Press this button to view the RLD system parameters menu.

Using the RLD

The following sections detail how to use the RLD.
After setting the parameters, RLD 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

Press Options of either channel for three seconds to enter the system parameters menu. The first parameter is “bu.” To navigate to the other three parameters, press the “Options” button. The sequence order of parameters to appear is as follows:

NOTE The “Options” button is also used to exit from this menu.

System parameter 1 – bulb type

The “bu” parameter defines the bulb type. It is important to define the type of bulb since each type has different electrical properties. The options are:

• Lb: Incandescent (Tungsten)
• CC: Cold Cathode
• FL: Fluorescent

CAUTION To ensure proper operation, cold cathode and and fluorescent lamp infrastructures require the installation of one incandescent lamp in line with these lamps.

NOTE If you change the bulb type, the Low Limit and Ignition Pulse parameters return to their default settings.

System parameter 2 – channel

The “ch” (Channel) parameter sets the connection mode. 0 represents connection via voltage-controlled mode using 0-10 VDC Analog input and 1-8 represents connection via the controller’s communication feature.

• Connecting via 0 – 10 VDC analog input: Set the parameter to 0. Refer to Using an analog output, page 17 for wiring information.
• Connecting via the controller’s communication feature: Set the parameter from 1 – 8. Each channel must be set to a different number (for example 01 and 02). Refer to Using a communication card, page 19 for further details regarding numbering.

NOTE The unit must be set to Auto Mode when working with a controller

System parameter 3 – low limit

The “Lo” parameter defines the minimum brightness limit (0%-99%). This parameter prevents lights burning out; the light only begins to operate when the brightness level reaches and exceeds this value. The light ceases to operate once the intensity level is 10% below the value in this parameter (for example: when set to 20% the light turns off at 18%). Default: 20%

NOTE The Lo setting cannot be higher than the br setting. The br setting cannot be lower than the Lo setting.

System parameter 4 – brightness restriction

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.

System parameter 5 – ignition pulse

When going from 0% brightness to any other brightness level, some cold cathode and fluorescent bulbs require full power for a brief period of time (milliseconds). This option supplies the required power. Since there are a large number of models on the market, each model having its own specifications, each user must test his model to verify if an ignition pulse is required and how long the pulse needs to run

• Default: None
• 1 – 5: Pulse length. 1 is the shortest and 5 is the longest.

NOTE Software versions 4.01 and higher support this option.

Bright mode

The Bright mode gradually increases the light intensity to the maximum value set in the “br” parameter. By default this process takes 20 minutes, but it can be adjusted through the “UP”  and “DOWN” cursor keys during Bright Mode operation. 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.

NOTE The system returns to the previous mode, at the point where it left off. For continuous operation, 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 RLD to a controller. There are two ways to connect the RLD to a controller:

• Via an analog output card 0-10 VDC (All Munters Controllers)
• Via a communication card (Platinum Controller only)

CAUTION Connect the RLD to a controller using one option only! Connecting the RLD using both methods together results in faulty light levels.
Refer to Configuring the channel levels, page 17 for information of connecting the unit to a controller.

Performing a Cold Star

Perform Cold Start to return the RLD to its default state:

1. Unplug the unit.
2. Reapply power; simultaneously press both arrow buttons.

The unit has been reset.

NOTE To check the software version, press the RESET button.

   Figure 7: RLD (Board Version 1.3.1) to RAOC-8 (Analog Output) Wiring Diagram

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 (Platinum and Super Guard/Pig Guard)
   • System parameters (AC-2000)

Using a communication card

1. . Connect the RLD to an RCLP card.

NOTE Verify that parameter “ch” is set to “1 – 8” (refer to System parameter 2 – channel,

2. Configure the channels. There are two numbering options:
   • Different numbers to each channel, with up to 8 different channels (when using multiple RLD units).
   • Same number for more than one channel if you require the same behaviors from these  channels.

For example, two RLD 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%

NOTE To control both channels simultaneously, short the terminals “0-10V A” and “0-10V B”.

Troubleshooting

CAUTION To ensure proper RLD operation, do not connect any inductive devices to the output (for example transformers, reactors, chokes).

• Check the power.
• Check the main fuse F3 and F1 (when working with 230 VAC).
• Check +5V.
• Check flat cable connection.

2| Power is ON, but there is no Output when working in “AUTO” mode with:

“0-10V” control voltage RX, TX communication lines

|

• Make sure the “+” and “COM” of “0- 10V” cable is connected correctly. Set 5V from controller and measure this value at the RLD terminal.
• Make sure the RX, TX are connected correctly (interchange RX and TX).

3| A blinking is observed when working at low voltage levels.| Make sure there are no inductive devices (for example transformers and power coils) load.
