16000 SERVICE/MAINTENANCE MANUAL INTRODUCTION
EPIC
®
Programmable Controller
The operating system is an EPIC
(Electrical Processed
Independent Control) with CAN-bus (Controller Area
Network) technology. The CAN-bus system uses multiple
nodes that contain remote controllers. The remote node
controllers communicate with the Node-1 (master) controller
by sending information data packets over a two-wire bus line.
The data packets are tagged with addresses that identify
each system component.
With the CAN-bus system, independently powered pumps,
motors, and cylinders provide controller driven control logic,
pump control, motor control, on-board diagnostics, and
service information. The MAX-ER data is shown on the
information screen in the operator cab (see Main Display
topic in Section 3 of the MAX-ER Operator Manual).
MAX-ER Wireless Remote Controls
To operate the MAX-ER wireless remote control see the
Operating Controls and Procedure in Section 3 of the MAX-
ER Operator Manual. Also, the MAX-ER Function mode
screen must be selected on the main display.
Power is available to the hand-held wireless remote control
when the engine is running, the MAX-ER function mode is
selected, and the power button is pressed. When a MAX-ER
wireless remote control is enabled, an input signal from the
wireless transmitter is sent to a receiver on the crane. The
receiver sends the input signal to the Node-1 controller. The
Node-1 controller sends an output signal to enable the MAX-
ER component in the direction or position selected.
Electrical System
Electrical cables WNE56 from the Node-4 controller and
WN56 from Node-0 on the crane provide input/out
connections to Node-7 on the wheeled counterweight
assembly.
