3.3 Abbreviations and Terms
Abbreviations/Terms Meaning Description
LED Light Emitting Diode: An electronic device used to indicate the
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 renews 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 8 matching lines of the Platinum Plus
/ AC-2000 controller.
"Lo" Low: This parameter prevents lamps from burning out through defining a minimum brightness limit. This value cannot be higher
than the Brightness Restriction.
"br" Brightness Restriction: By this parameter one can restrict the upper limit of the output voltage. Its values can be within "On"
(100) and "0" (0%), but it must be higher than the “Lo” parameter.
3.4 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.

9 RLD |3.0/4.01
1. Arrow 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.
8. Options: Press this button to view the RLD system parameters menu.

4 USING THE RLD DIGITAL
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
•Bright Mode
•Manual Dim Mode
•Auto Mode
•Performing a Cold Start
4.1 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: bu Ch Lo br Ig.
NOTE: The "Options" button is also used to exit from this menu.
•System Parameter 1 – Bulb Type
•System Parameter 2 – Channel
•System Parameter 3 – Low Limit
•System Parameter 4 – Brightness Restriction
•System Parameter 5 – Ignition Pulse
4.1.1 System Parameter 1 – Bulb Type
The "bu" parameter defines the bulb type. It is important to correctly 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.
4.1.2 System Parameter 2 – Channel
The "ch" (Channel) parameter sets the connection mode. 0represents 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 18 for wiring information.
•Connecting via the controller’s communication feature: Set the parameter from 1 – 8. .
Refer to Using a Communication Card, page 20 for further details regarding numbering.

11 RLD |3.0/4.01
NOTE: The unit must be set to Auto Mode when working with a controller (refer to Auto Mode, page 12).
CAUTION Platinum Controllers only suppport channels 1 – 4.
4.1.3 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.
4.1.4 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.
4.1.5 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.
4.2 Bright Mode
The Bright mode gradually increases the light intensity to the maximum value set in the "br" parameter.
This process takes 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.
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.
4.3 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.

RLD |3.0/4.01 12
4.4 Auto Mode
Pressing the "Auto" button enables connecting the RLD-14 to a controller. There are two ways to connect
the RLD-14 to a controller:
•Via an analog output card 0-10 VDC (All Rotem 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 18 for information of connecting the unit to a controller.
4.5 Performing a Cold Start
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.
