Atlas Copco Blasthole Drills RCS for the Pit Viper series Rig Control System In its fifth generation, RCS continues to be more productive than ever. The latest RCS technology has advanced safety capabilities, serviceability and drilling accuracy. With CAN-bus technology providing the backbone, ease of system upgrades and add-ons without major machine rebuilds are testaments to RCS’s flexibility and agility.
Rig Control System A History of Excellence In 1998, Atlas Copco introduced its Rig Control System (RCS) technology that has revolutionized the mining industry. Now in its fifth generation, RCS continues to keep Atlas Copco in the forefront of blasthole drilling technology development. The ingenuity of RCS provides direct impact to your safety, efficiency, and productivity through a computerized control system. 2

RCS is based off time proven CAN-bus technology.
As an integrated control system, the rig is gover
ned, monitored, and all required information is
conveyed to the operator as well as orders ex-
ecuted. This flexible and agile technology contin-
ues to power RCS and tackle automation goals.

Straightforward
Engine Control Module
While not directly part of RCS, the ECM plays a
pivotal role. Providing valuable engine data for
the display, RCS will alert the operator when
conditions exist outside the normal parameters
by allowing possible equipment saving deci-
sions to be made.
Sensors, actuators, and control devices
Integral components provide the moving,
measuring, or sensing in RCS. Depending on
the usage, these components either send mes-
sages back to the computer or initiate actuation
commands.
Features:
• “Eyes and ears” of RCS to maintain full
awareness, while providing safety interlocks.
• Provides the operator the ability to
“fly by wire” for actuating devices.
• Most equipped with LED’s for quick trouble-
shooting.
MC2
The MC2 Controller monitors the flow and pres-
sure inputs, operator inputs and engine data. It
controls the butterfly valve and vent valve actua-
tors to achieve the required flow and pressure.

Operator Environment
Left and Right Operator Panels
Built into the armrests of the chair, the left and
right operator panels literally put the controls of
the drill at the operator’s fingertips, using multi-
function joysticks and push-buttons.
Display/Computer
The 12.1” infrared display acts in two capacities
for RCS: the rear houses the heartbeat of RCS
(the central computer) and the front provides
the operator direct awareness of what actions
the drill and its systems are performing.
Features:
• Ergonomically built into chair armrests
• Operator retains control of the drill while
actively aware of surroundings.
• Backlit buttons for ease of use in nighttime
operations
• Identical operator panels across the RCS Pit
Viper fleet; means operator learning curve
dramatically reduced
• Joysticks have friction lock for ease of placing
them in neutral and rocker switch for safety
• Identical operator stations across the RCS Pit
Viper fleet; operator learning curve dramati-
cally reduced
• Display in a non-obtrusive location; operator
will continually have focus on operations with
complete awareness of the drill

Add-on Features
RCS is more than it shows
at first glance.
As a modular control system, field and factory installed add-on
features are all possible as your mining requirements grow.
