MH3037 Material Handler Caterpillar

Note: For additional information regarding the monitoring system, refer to System Operation, Troubleshooting, UENR5821, "MH3037 Material Handler IQAN Electronic Control System".

General Information

The Master Controller and Monitor (MD3) were designed to aid in operation of the machine.

The monitor provides many useful functions for the operator for increased work productivity and safety. Some of the features include:

• Gauge panel and operational indicators

• Operational machine output data

• Work tool and hydraulic controls

• Performance enhancement controls

• Operational event warnings

• Maintenance intervals and diagnostics

Master Controller and Monitor (MD3)

The machine control system consists of the following:

• Master Controller and Monitor (MD3)

• Master Controller (MC2)

• Electronic Control Modules (XA2)

Master Controller and Monitor (MD3) - Master Controller and Monitor (MD3) is the operator interface unit in the machine's multi-master control system. Master Controller and Monitor (MD3) masters three CAN (Controller Area Network) busses for connection to other units. The busses support ICP (IQAN CAN Protocol) and are able to communicate with other IQAN units in this system and the Master Controller (MC2). SAE J1939 is also supported on the CAN busses and gives the ability to interface with Caterpillar ECMs and machine control panels. Four function buttons and five navigation buttons combined with a graphical display makes system feedback with user interaction possible.
The display has a high optical performance across a wide operating temperature range and over a wide range of ambient light. Master Controller and Monitor (MD3) has voltage and digital inputs and low-power digital outputs. All inputs and outputs are EMI filtered and protected against short circuit to -BAT and +BAT.

Master Controller (MC2) - The Master Controller (MC2) has inputs and outputs for control, and can communicate with IQAN masters, expansion modules or other CAN devices. In this multi-master application, the Master Controller (MC2) module is used to expand system memory and control. The IQAN Project, machine control program, resides in both the Master Controller and Monitor (MD3) and Master Controller (MC2) modules. The Master Controller (MC2) communicates with the Master Controller and Monitor (MD3) on a dedicated CAN bus MD3 CAN-A. It masters another CAN bus MC2 CAN-B for Electronic Control Module (XA2) and joystick communications.

Electronic Control Module (XA2) - The Electronic Control Module (XA2) has voltage, digital, and frequency inputs. The outputs are proportional PWM and digital. The Electronic Control Module (XA2) module communicates with the Master Control (MC2) master controller over a CAN bus MC2 CAN-B. The MH3027 is equipped with three Electronic Control Modules (XA2).

(11) Hydraulic Temperature Gauge - Indicates the temperature of the hydraulic oil. The indicator will remain gray when the temperature is in the normal operating range. The indicator will flash red and an audible alarm will sound when the temperature is too high. Stop the machine and investigate the cause of the problem.

(12) Engine Coolant Temperature Gauge - Indicates the temperature of the engine coolant. The indicator will remain gray when the temperature is in the normal operating range. The indicator will flash red and an audible alarm will sound when the temperature is too high. Stop the machine and investigate the cause of the problem.

(13) Diesel Exhaust Fluid (DEF) Level Gauge - This gauge indicates the amount of DEF that is remaining in the DEF tank. When the DEF gauge indicates that the DEF level is in the red range, add DEF, immediately.

(14) Fuel Level Gauge - Indicates the amount of fuel that is remaining in the fuel tank. The indicator will start flashing and an audible alarm will sound when the fuel level is below 10%.

(15) Engine Oil Pressure Gauge - Indicates the pressure of the engine oil. The indicator will remain gray when the oil pressure is in the normal operating range. If the indicator blinks red, and an audible alarm sounds, the oil pressure is too low. Stop the machine immediately. Stop the engine and investigate the cause of the problem. Do not operate the machine until the cause of the problem has been corrected.

(16) Generator Current - When the magnet is enabled, a gauge will appear to indicate the generator current.

(17) Engine Speed Gauge - This gauge indicates the engine speed. The engine speed at low idle is 800 rpm. High idle engine speed is 1850 rpm.

(18) Travel Mode Indicator - Indicates the current mode of travel speed available. Creeper Mode – When this indicator is shown, the creeper mode is active. The percentage of maximum creeper mode speed available will be displayed below the indicator. Fast Mode – When this indicator is shown, the fast mode is active. The percentage of maximum fast mode travel speed available will be displayed below the indicator.

(19) Oscillating Axle Lock Control Mode - Alerts the operator to the control mode selected for the oscillating axle lock cylinders. "AXLE LOCK: SET" axle will not oscillate. "AXLE LOCK: RELEASED" axle will oscillate. "AXLE LOCK: AUTO" axle will oscillate during travel, and not oscillate 5 seconds after travel stops. Check machine icon for current oscillating axle lock cylinder status.

(20) Machine Indicator - This icon illustrates the position of the machine and indicates the operational status or functionality of machine components. Refer to "General Information" for additional information.

(21) Operator Memory - Operator memory is a set of parameters and preferences that are saved in the memory of the monitor as an operator name. Four operator names are saved in the memory and can be recalled for different operators or different work conditions. Default operator names that may appear on the monitor are "Operator (1-3, and Fine Control)". An operator can select which operator name to use on the Operator Selection Screen, accessible from the Machine Status Display Screen (F2).

• "Generator Fault Log" - Records of magnet controller codes from J1939 Data Link

The system and MC2 logs will have many records. All logs can be cleared using IQANrun on a computer connected to the USB diagnostic port below the monitor. Dealer login or higher security is required to clear log records. Contact your Cat dealer. A log cleared will be recorded during the process and the record count will display "1". Cleared logs do not return to 0 records, because one record is retained as, "Log cleared" with IQAN license identification.
