RC-300W Remote Controller

The panel of the instrument can be removed for wireless remote controller RC-300W.
To remove the RC-300W, first push it up then pull it straight away from the instrument.

Operating the RC-300W

The RC-300W will always operate the RT-5SW while attached to
the unit. It will also operate the RT-5SW remotely when detached
from the instrument.
The RC-300W both sends and receives information from the RT­5SW when it is used within 300 m (984ft) of the instrument.
When attached to the RT-5SW, the RC-300W receives its power
from the instrument. In remote operation, the RC-300W must have
batteries installed. See “Maintaining Power Sources” sect ion.
When entering information in the RC-300W, you must always press
the [ENT] key to send the information to the RT-5SW.
The [OK] indicator is displayed on the RC-300W LCD to confirm
communication with the RT-5SW. If communication fails, [NG] is
displayed.
The remote control will automatically turn off about 60 seconds after
the last time any key is pressed or after leveling is completed (auto
cut off function). To reactivate the RC-300W, press the power
switch once.

When using the remote controller, raise the remote controller antenna.

• 1) The working range of the remote controller is up to a distance of about 300 m from
the instrument.

• 2) It is necessary to install batteries when using the remote controller. Install the
batteries by referring to “Maintaining Power Sources” on page 39. The power supply
of the remote controller is drawn from the instrument when attached.

• 3) The power of the remote controller shuts off automatically after about 60 seconds
when key or leveling operations have been completed (Auto Shutoff Function). Press
the power switch once to restore power to the remote controller after the auto shutoff
function has been activated.

Common use of RC-300W remote controller

RC-300W remote controller is available for number of RT-5SW. When you are using plural RT­5SW at your job site, you can use your RC-300W for the other RT-5SW unit. Change the
channel to receive the internal data of each RT-5SW to the RC-300W by operating the RC­300W.
This function enables to operate RC-300W without re-attach to every RT-5SW which you are
using. The data of each unit can be transmitted to the RC-300W before operating.

Automatic Alignment

Automatic Alignment makes precise grade axis alignment very easy.
To prepare the instrument for Automatic a lignment, X and Y axes must be roughly aligned to
within 10 degrees of the true axis desired. This can be done by using the molded sights of top of
the instrument housing.
The RT-5SW alignment target is then positioned directly on the grade axis desired up to 150
meters (492 ft) away from the instrument.

• 1)The maximum distance the target can be away from the RT-5SW is 150m (492ft).

• 2)The target must be positioned so it is centered on the grade axis desired and UP
arrow is facing up.

• 3)The reflective side of the target must face the RT-5SW.

RT-5SW LED display

(visible when RC-300W is removed)

When the RC-300W is detached from the unit, a LED is visible. It provides a quick status check
on the RT-5SW as follows:

Yellow flashing:

Auto-leveling or grade setting is in process.
The rotary head is not rotating.

Yellow ON solid:

Auto-leveling grade setting is complete.
The rotary head is active and emits the laser beam.

Red quick flashing:

1) The instrument is positioned beyond auto-leveling range (±5°).
Reposition the instrument into range and LED should begin normal flashing.

2) Error has occurred. If Height Alert function is active, unit may have been
disturbed (see previous section). RC-300W will also indicate error code.
See “Error Display” section.

Red flashing:

Indicates the current channel on the remote control for the instrument. The
channel on the instrument can be identified from the number of blinking times
after long illumination.

You can stop the auto-levelling function. Refer to “Function Mode” on page 33 to stop
the function.

30

Masking (Laser beam shutter)

The RT-5SW features electronic beam “masking” to prevent the beam from transmitting on one
or multiple sides of the instrument. Due to the long beam range of the RT -5SW , this can be useful
to eliminate duplicate laser beams on large job sites where more than one laser may be in use.
The use of masking has no effect on power usage.

1 Press the Mask key on the RC-300W.

With no masking active the display will
be as shown.

2 Select one or more directions to mask

by pressing the arrow keys (Y+, X-, Y-,

Function Mode

The RT-5SW has seven function modes the user can set.

1) Laser Output Power (POWER)

Two levels of laser output are possible:

HIGH (4.5mW) LO (2.5mW)
The high power mode should be used when necessary due to long range requirement,
otherwise the low power mode will provide longer battery life.

2) Sensitivity Level (LEVEL)

The sensitivity mode allows the user to select the vi bration level that is necessary
to cause the unit to re-activate auto-leveling. This function is valuable when the RT ­5SW in windy or other conditions that cause unnecessary auto-leveling activity.
Two sensitivity levels can be set, plus manual operation.

Level One [1]: Least sensitive. Auto-leveling will not activate with moderate vibration.
Level Two [2]: Most sensitive. Smallest vibration will cause auto-leveling activity.
M(Manual): Auto-leveling function, Auto-a lignment and Setting grade are turned off.

1) Laser Output Power (POWER) 2) Sensitivity Level (LEVEL) 3) Height Alert (ALERT)

4) Alarm Signal (COM) 5) Changing Masking Mode 6) Setting the target

7) Channel Setting

Do not use manual level [M] except for special circumstances. If manual [M] is
selected, the Automatic alignment, Automatic grade setting and X,Y - grade setting
function will not operate and leveling and grade setting precision cannot be
assured.

34

3) Height Alert Function (ALERT)

When active, the Height Alert function will not allow the RT-5SW to continue operating if the
unit is disturbed after it has auto-leveled. This reminds the user that to insure accurate
control. (When COM is ON)

ON: Height Alert active OFF: Height Alert inactive

4) Alarm Signal (COM)

When used with the Topcon LS-70A laser sensor, the RT-5SW can communicate alarm
signals directly to the sensor. This helps enable the user to be completely aware of potential
problems before they can become serious.

ON: Alarm Signal is active OFF: Alarm Signal is inactive

Check and Adjusting

There are three areas of performance the user should check periodically.

Horizontal Calibration
Horizontal Rotation Cone

Grade Setting
The Horizontal Calibration can be easily checked and, in most cases, adjustments made by the
user. Both Horizontal Rotation Cone and Grade Setting can be checked by the user, but should an
error be found, adjustments must be made by a Topcon service facility.

Horizontal Calibration

(1) Checking Calibration

1 Set up a tripod 50m(164ft) from a staff or wall. Mount

the instrument on the tripod, facing the “X-” axis toward
the staff/wall.

2 Remove the RC-300W from the instrument.
3 While pressing the Function [F] key of the RC-300W

press the power switch to turn on the instrument. This
activates the calibration mode.

Always be sure the RC-300W is within two-way
communication while checking and adjusting the
instrument. If the RC-300W displays error code [COM
ERR TURN OFF / TURN ON] any time during the
procedure, turn the instrument OFF and ON again and
repeat the procedure from the beginning.

4 Select the axis you wish to check (X or Y) by press

the [X] or [Y] key. Press the [ENT] key. (These
instructions will assume the X axis was chosen.)

After communication between the RT-5SW and the
RC-300W is complete, the unit will automatically
adjust to the position selected and auto-leveling will
start. The yellow LED on the instrument will flash.
When auto-leveling is complete, the rotary head will
rotate and emit the laser. The RC-300W will display
“X:1”.

5 Turn on the LS-70A laser sensor, and select fine

detection mode.

6 Use the LS-70A to detect the laser beam on the

staff/wall. Move the sensor up or down until the LCD
indicator and audio signal identifies the center of the
laser beam. Fix the LS-70A in that position on the
staff or wall.

The RT-5SW will automatically rotate internally to
orient the axis selected to the staff/wall. It is not
necessary to manually rotate the instrument any
time during the procedure. Therefore calibration
checking and adjusting is much faster and easier
than the user may have experienced with other
instruments.

Select an axis and press [ENT].

7 Press the [ENT] key on the RC-300W. The unit will

rotate 180 degrees internally and start auto­leveling. The RC-300W will now display “X:2”.

8 When the rotary head starts rotating, do not move

the LS-70A laser sensor to locate the beam center.
Instead, note the beam location as shown on the
laser sensor display. If one of the three center LCD
indicators is lit (center bar, Down arrow-point, Up
arrow-point) calibration is OK and no adjustment is
needed. Repeat steps 4-8 for the remaining axis (Y
in this example).

If adjustment is necessary proceed to the
“Adjusting” instructions below before checking the
remaining axis.

X:2

Press [ENT]

The unit turns to 180° and starts auto­leveling.

Note the position of the X2 laser
beam on the LS-70A display. If
one of the three center indicators
is lit, no calibration adjustment is
necessary.

46

(2) Adjusting Calibration

1 By pressing the UP or DOWN arrow keys on the

RC-300W, move the rotating laser beam up or down
as necessary until the center bar on the LS-70A
display is lit. (This will be the same position as
center of “X:1” and “X:2”.)

While the beam is moving, RC-300W displays
“ADJUSTING”.

2 When the center bar lit on the LS-70A, press the

[ENT] key on the RC-300W.
The correction value will be calculated by the RT­5SW and transmitted to the RC-300W. When the
transmission is completed, the display shows
“PUSH (ent) KEY”.

X:2

Move the X2 rotating laser until the center bar of the
LS-70A display is lit.

When the center bar is lit, press [ENT].

3 Press the [ENT] key to complete the calibration.

The RC-300W display will return to the axis
selection screen.
If an axis remains to be checked, begin at step 4 of
“Checking Calibration”.

4 To complete the calibration procedure, press the

power switch to turn the instrument off.

In order to perform the Automatic grade setting more accurately, it is recommended that
the error be adjusted within ±2 mm.

If the correction value calculated exceeds the allowable range, the RC-300W will display
error code [CAL LIMIT]. Check the procedure again and perform any inspections and
adjustments.

X: Y:

Turn the instrument OFF to finish the
calibration.

48

Horizontal Rotation Cone Error

Perform the following check after completing “Horizontal Calibration” on the previous
page.

1 Set up the laser centered between two walls approximately 40m (131 ft) apart. Orient the

instrument so one axis, either X or Y, is facing the walls. Grade should be set to 0.00% in both
axes.

2 Locate and mark the position of the rotating laser beam on both walls using the LS-70A laser

sensor.

3 Turn off the instrument and move the instrument closer to wall A (1m to 2m /3 ft to 6 ft).

Do not change the axis orientation of the instrument. Turn the instrument on.

4 Again locate and mark the position of the rotating laser beam on both walls using the LS-70A

laser sensor.

5 Measure the distance between the first and second marks on each wall.
6 If the difference between each set of marks is less than ±4mm (±5/32 of an inch), no error

exists.

If the difference between [wall A]-side and [wall B]-side exceeds ±4mm (±5/32 of an
inch), contact your dealer or Topcon.

Grade Setting Error

Perform the following check only after completing “Horizontal Calibration” and
“Horizontal Rotation Cone Error”.

(1) Checking

1 Securely position two nails or stakes exactly 30m (93 ft) apart. These positions will be called

Nail 1 and Nail 2.

2 Set up the instrument on a tripod approximately 1m to 2m (3 ft to 6 ft) in front of Nail 1 on the

line created by Nail 1 and Nail 2. Position the instrument so the “X-” axis is directly on the line
created by Nail 1 and Nail 2.

3 Turn on the instrument and verify the grade setting is 0.00% in both axes. T urn on the LS-70A

laser sensor and set it to high precision detection. Using the staff, read the elevation of the
laser beam in millimeters at Nail 1 and Nail 2. Designate the elevation at Nail 1 as “h1”, at Nail
2 as “h2”.

Due to the accuracy required to perform this check, the staff used in this procedure must
be graduated in millimeters.

Level

4 Set X axis grade to 1.00%. Align read the elevation of the laser beam in millimeters at Nail 1

and Nail 2. Designate these elevations as “h3” at Nail 1, and “h4” at Nail 2.

5 Using the elevation readings for h1, h2, h3 and h4, complete the equation below.

If the calculated result is the range of 0.990% - 1.010%, the instrument is normal.
Repeat the procedure aligning the “Y-” axis on the line created by Nail 1 and Nail 2.

Example; h1 = 1370; h2 = 1390; h3 = 1362; h4 = 1080

X%=(1390-1080)-(1370-1362)

X 100 = 0.010066 X 100 = 1.006%

30000

The X axis of instrument is normal because 1.006 is within the range 0.990 to 1.010.

If the calculated result for either axis is out of the range, contact your dealer or Topcon.
