d) Plumb Indicators
Blink rapidly to show the vertical position of the machine’s arm. (See below.)
e) Low Battery Indicators
Become lit when the battery pack has less than 6 hours of operating charge.
f) Cable Connector
Provides a connection to a control panel or to a 12 or 24 Volt DC battery. Use
sensorbatterycable toconnecttoabattery:theblackwire to negative; the white
wire to positive.
Shake-to-Wake:
After 5 minutes of no movement, the laser sensor goes into “stand-by” to
conserve power. Move the laser sensor to activate it (after 90 minutes of no
movement, it shuts completely off).

Description of the System
g) Mounting Clamps
Allow you to easily attach the laser sensor to square and round mounting poles
without having to lift the laser sensor over the top of the pole. The laser sensor
includes shock isolators to absorb and dampen vibrations from the machine.
Magnetic Mount:
Allows the sensor to be attached to the arm of the machine.
Remove by pulling sharply from a lower corner of the magnet.

h) Battery Pack
The rechargeable batteries provide power to the laser sensor for over 48 hours
on a single charge.
Recharge the battery pack by connecting a 778855 Charger, 100-240 VAC to
the charger connector.
Plug the DC power cable into the battery pack before plugging it into the mains
socket.
i) Narrow/Wide Switch
Remove the battery pack before activating the wide/narrow switch. The wide
channel is for wide band operation and the narrow channel is for narrow band
operation.

Operation MC200 3-2
3.1 Battery
First-time use/charging
• The battery must be charged prior to using it for the first time because it is deliv-
ered with an energy content as low as possible.
• For new batteries or batteries that have been stored for a long time (> three
months), it is effectual to make 3-5 charge/discharge cycles.
• The permissible temperature range for charging is between 0°C to +35°C/+32°F
to +95°F. For optimal charging we recommend charging the batteries at a low
ambient temperature of +10°C to +20°C/+50°F to +68°F if possible.
• It is normal for the battery to become warm during charging. Using the chargers
recommended by Leica Geosystems, it is not possible to charge the battery if
the temperature is too high.
Operation/Discharging
• The batteries can be operated from -20°C to +55°C/-4°F to +131°F.
• Low operating temperatures reduce the capacity that can be drawn; very high
operating temperatures reduce the service life of the battery.

Operation MC200 3-4
Procedure 1. Set up and level the Rotating Laser in a convenient location.
Make sure there will be a clear path between the rotating laser and laser sensor
at all times and that the laser signal will be within the 200° range of the laser
sensor.
2. Activate the laser sensor.
• Ifin“stand-by,”movethearmtoshake the lasersensorandstartit.Otherwise,
press the Power Button for the side(s) you will be viewing.
• If connected to the machine’s battery, it is on.
• If connected to a Control Panel, put the Control Panel’s Power Switch to
ON.
3. Begin digging and stop when the excavation is at the required depth.
Position the bucket and set it down at the finished elevation.
The bucket can be in any position, but it must be in the same position each time
you make a grade check.
4. Plumb the laser sensor.
Adjust the machine’s arm so the center Plumb Indicator is blinking.
5. Loosen the laser sensor’s Mounting Clamps and slide it up or down until
the “On-Grade” Grade Position Indicator is blinking.
When using the Laser sensor with magnetic mounts, place the laser sensor in
the bracket and set it at the correct height on the arm of the machine before

attachingit.When using mounting clamps, tightenthe lasersensoratthecorrect
height.
6. Continue digging until a grade check is normally required and take a grade
check.
• Move the bucket to the same position as it was in Step 3 and lower it almost
to the cut.
• Plumb the laser sensor by moving the machine’s arm in or out until a center
Plumb Indicator is blinking.
• Set the bucket on the cut and read the elevation next to the blinking Grade
Position Indicator.

Operation
Procedure 1. Set up and level the Rotating Laser in a convenient location.
Make sure there is a clear path between the Rotating Laser and the MC 200
Depthmaster laser sensor.
2. Move the machine to the area to be graded and set the blade to a position
that is at finished grade, such as a Hub Stake or a “Blue Top.”
3. Set the Control Panel’s Auto/Manual Switch to "MANUAL" and set the
Power Switch to "ON".
4. Loosen the laser sensor’s Mounting Clamps and slide it up or down until
the “On-Grade” Grade Position Indicator is blinking
(It may be necessary to raise or lower the Rotating Laser). Tighten the Mounting
Clamps.
5. Operate the machine:
• Manual Mode. Begin moving the machine forward while observing the Grade
Position Indicators on the laser sensor or Control Panel.
Use the machine’s controls to keep the “On-Grade” Grade Position Indicator
blinking.

3.4 Optional Functions
Switching to
Machine Control
Mode
The MC 200 Depthmaster can be made to operate as an excavator sensor or as a
machine control sensor. To switch between these modes - turn on the sensor, then
press the marked switch left of the Leica Logo.
In machine control mode, only the top three lights will function and the sensor will be
in narrow band.
Disabling Sleep
Mode The MC 200 Depthmaster will go into a “sleep mode” if no movement is seen in the
plumb indicator lights after five minutes. In certain applications (ie: dozers,
trenchers) it is desirable to disable this function.
3-9MC200
Operation
To disable the
sleep mode - Turn
off the sensor.
Press and hold the marked switch left of the Leica Logo, then turn on the sensor.
The sensor will go through it’s normal power-up sequence, then the two outer plumb
lights will flash to indicate the sleep mode has been disabled. Now let go of the
"hidden switch" and sleep-mode is disabled, the laser sensor is set to permanent
operations. The sleep mode must be disabled each time the sensor is turned on.
