1.3How to Adjust Display Brilliance
To adjust the display brilliance, press T, S, or DAY/NT key. The setting range is 0 to 9. "0" is off
and "9" is the brightest.
Operation with main RD-20
The main RD-20 simultaneously controls the display brilliance of the main RD-20 and the sub
RD-20s.
• Controls with T key: Decrease the display brilliance.
• Controls with S key: Increase the display brilliance.
Operation with sub RD-20
When you want to individually adjust the display brilliance for each sub RD-20, do as follows:
• Controls with T key: Decrease the display brilliance. (The variation is smaller than that of the
main RD-20 and RD-502 connected to the main RD-20.)
• Controls with S key: Increase the display brilliance. (The variation is smaller than that of the
main RD-20 and RD-502 connected to the main RD-20.)
Operation with RD-502
The RD-502 simultaneously controls the display brilliance of the main RD-20 and the sub RD-20s.
• Controls with T key: Decrease the display brilliance.
• Controls with S key: Increase the display brilliance.
• Controls with the DAY/NT key: The display brilliance changes as shown in the table below with
every press of the key.

2.MAINTENANCE, TROUBLESHOOTING
NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating
or plastic parts of the equipment.
Those items contain organic solvents
that can damage coating and plastic
parts, especially plastic connectors.
2.1Maintenance
Check the following points regularly to maintain performance:
• Check that connections on the rear panel are firmly tightened and free of dust.
• Check that the ground system is free of rust and the ground wire is tightly fastened.
• Remove dust or dirt from the cabinet with a soft, dry cloth. For stubborn dirt, you can use water-
diluted mild detergent. Clean the cabinet with a dry cloth after you use detergent. Do not use
solvents like thinner, acetone or benzene to clean the unit. They can remove paint and indications.

2.2Life of the Parts
Fuse replacement
The fuse in the remote display protects the equipment from overcurrent and equipment fault. If the
fuse blows, find the cause before you replace the fuse. Use the correct fuse. A wrong fuse can
damage the equipment. See the outline drawings about the location of the fuse.
WARNING
Use the correct fuse.
A wrong fuse can damage the equipment
and cause fire.

LED life
The life of the LED is approximately 46,000 hours. The actual number of hours depends on ambient temperature and humidity. The consumption current depends on the number of lighting
LEDs and the LED brilliance.

2.4Diagnostic Test
The diagnostic test checks the system for correct operation. There are two types of diagnostic
tests; automatic test and key test.
Automatic test
1.While you hold down the UNIT key, press the PWR key to turn on the power.
2.Press the MODE key. The automatic test starts. To stop the test, press the PWR key.
Note: You can extend the display time for a screen by three seconds. Momentarily press any
key (except the PWR key) at the desired screen during the test. You can do this procedure up
to 10 times, that is you can extend the display time to a maximum of 30 seconds.

The remote display can be installed on a desktop, on the overhead, or flush mounted in a panel.
When you select a mounting location, keep in mind the following points:
• The nominal viewing distance for the display unit is 2.0 m. Select a suitable mounting location
considering that distance.
• Locate the unit away from exhaust pipes and vents.
• Locate the unit out of direct sunlight.
• Select an installation location that is well ventilated.
• Mount the unit where shock and vibration are minimal.
• Locate the unit away from equipment which generates the electromagnetic fields like a motor
or generator.
• Allow enough maintenance space at the sides and rear of the unit. Leave enough slack in cables to facilitate maintenance and servicing.
• Observe the compass safe distances (see page ii) to prevent interference to a magnetic compass.

Flush mounting
1.Make a cutout in the mounting location (132 mm (width) x 120 mm (height)).
2.Make four pilot holes for self-tapping screws (diameter: 3 mm) in the location indicated in the
illustration below.
3.Insert the sponge to the remote display from the rear side.
4.Set the remote display to the cutout and fasten the remote display with four self-tapping
screws (M3x15).
5.Set a cosmetic cap to each fixing screw on the front panel. (See “How to set the cosmetic cap”
on page 20.)

Note: If it is more convenient to connect cables before you install the remote display, first connect the cables referring to the section 3.4.
Desktop or overhead mounting
You can mount the remote display on a desktop or on the overhead using the optional hanger
(Type: OP26-1, Code No.: 000-016-195-00).
1.Insert the hanger mounting plate to the remote display from the rear and fasten the hanger
mounting plate from the front of the remote display with four binding head screws (M3x12).
2.Fix the bottom of the hanger to the mounting location with four self-tapping screws (4x16).
3.Insert a washer to each knob (right and left) and fix the knobs to the remote display loosely.
4.Slip the screw parts of the knobs to the slit of the hanger and set the remote display to the
hanger.
5.Tighten the knobs to fasten the hanger to the remote display.
6.Set a cosmetic cap to each fixing screw on the front panel. (See “How to set the cosmetic cap”
on page 20.)

How to set the cosmetic cap
Set a cosmetic cap to each fixing screw on the front panel as shown below.
Set cosmetic cap to hole so cap is flush with panel.
3.3Installation of Remote Controller and Dimmer
Controller
The optional remote controller RD-501 and dimmer controller RD-502 can be flush mounted in a
panel. The size and the mounting procedure are shared by RD-501 and RD-502. For the mounting
location, refer to the mounting considerations for the remote display in section 3.2.
Flush mounting
1.Make a cutout in the mounting location (88 mm (width) x 76 mm (height)).
2.Make four holes of φ4 in the location indicated in the illustration below.
3.Set the remote controller or dimmer controller to the cutout. Insert four binding head screws
(M3x12) from the front side then fasten the unit with four sets of flat washers, spring washers
and hexagonal nuts from the rear side.

3.6JIS Cable Guide
Cables listed in the manual are usually shown as Japanese Industrial Standard (JIS). Use the following guide to locate an
equivalent cable locally.
JIS cable names may have up to 6 alphabetical characters, followed by a dash and a numerical value (example: DPYC-2.5).
For core types D and T, the numerical designation indicates the cross-sectional Area (mm
For core types M and TT, the numerical designation indicates the number of core wires in the cable.
