Hitachi ZAXIS ZX160-3 to ZX850-3 Excavator Dr.ZX Diagnostic Operation Manual

Description

The Hitachi ZAXIS ZX160-3 to ZX850-3 Excavator Dr.ZX Diagnostic Operation Manual is the authoritative technical reference for running Dr.ZX — Hitachi Construction Machinery’s electronic diagnostic and service software — on ZAXIS ZX-3 series hydraulic excavators. It is written for the experienced technician and walks through every step of connecting the tool, pulling self-diagnostic results from each controller, reading real-time sensor and switch data with the machine running, editing machine parameters and attachment settings, and decoding the complete fault code library for the MC, ECM, ICF, monitor unit, and satellite terminal. Sections are provided separately for the Palm-based Dr.ZX workflow and the Personal Computer (Windows) workflow, so the manual stays useful whichever platform a workshop is running.

Chapters and Contents Covered

• Section 1 — Outline: What Dr.ZX is, what controllers it connects to (MC, ECM, ICF, monitor unit), the difference between Self-Diagnostic Result and Controller Diagnosis modes, and how performance standards and test data are evaluated.
• Section 2 — Operation (Palm): Dr.ZX Palm setup, communication check, password setup, service software selection (ZX-3 Mid for ZX160-3 to ZX330-3; ZX-3 Large for ZX450-3 to ZX850-3), Self-Diagnostic Result, Select Controller, Main Controller (Monitor Display, Special Function, Setup, Recorded Data Display, Password Change), Engine Controller (Monitor Display, Data Upload From ECM, Data Download To ECM, Write Injector ID Code, ECM Data Display, Actuator Test, Record Data Display, Password Change), ICF Controller (Information C/U Various Setup, Data Download, Save Data Check, Password Change), and Monitor Controller (Monitoring, Various Settings, Optional Function Allocation, Overload Alarm Enable/Disable, Back Monitor Setting, Operating Condition Enable/Disable, Time Setting Function, Maintenance Setting, Notification Function, Maintenance Display Item selection, Fuel Consumption Gauge Display, Password Change).
• Section 2 — Operation (Personal Computer): Dr.ZX PC start-up, communication port confirmation (Windows 2000 and Windows XP), Data Download and Download History Confirmation, Trouble Shooting per controller, Monitoring across Main C/U, Engine C/U and Monitor Unit, Machine Setting (Parameter Change, ATT Parameter Change, Special Function), and Attachment Setting on the Monitor Unit.
• Section 3 — Adjustment Data (Palm and PC): Per-class adjustment tables listing the minimum adjustment value, adjustable range, standard adjustment, and units for Li Speed, WU Speed, AI Speed, E/P/HP Speed, PQ torque, pump torque, ATT proportional valve, ATT torque reducing, ECO / HP / theft-prevention toggles, boom cylinder bottom-pressure over balance, lubrication interval, pump minimum displacement, pump cutoff pressure, and P1 / P2 regulator offsets.
• Section 3 — Attachment Adjustment Data: Attachment-by-attachment tables for ATT1 through ATT5 covering ATT Type (BR / PU / CR / VI / Un / Non), ATT Number, P1 and P2 Max Swash Angle, Engine Speed Increase/Decrease, Secondary Pilot Relief, Selector Valve, Accumulator, and 2-Speed selection.
• Section 4 — Fault Code (ZX160-3 to ZX330-3 class): Full fault-code lists for MC (controller hardware, engine, pump, pilot, proportional solenoid, CAN data reception, other), ECM, ICF, satellite terminal, and monitor unit, each with trouble, cause, influenced control, symptoms in machine operation, and Remedy for Dr.ZX.
• Section 4 — Fault Code (ZX450-3 to ZX850-3 class): The matching fault-code library for the larger ZX-3 machines across MC, ECM, ICF, satellite terminal, and monitor unit, including the ZX850-3 hydraulic-oil overheat alarm.

Together these sections give a technician the full Dr.ZX workflow for the ZAXIS ZX-3 range: what to plug in, how to configure the software, how to read live machine signals, how to safely change working parameters, how to load and store ECM data, how to write injector ID codes when a cylinder injector is replaced, and how to interpret the fault codes that Dr.ZX returns across every controller on the machine.

What Dr.ZX Diagnoses on a ZAXIS ZX-3

Dr.ZX is used for diagnosis of the electrical system including MC, ECM, ICF, and monitor unit. This manual opens by explaining exactly what the tool does: it connects to ICF, displays the failure of each controller and each sensor as a fault code (Self-Diagnostic Result), and simultaneously shows the input status of sensors and switches as well as the output status to actuators including solenoid valves, with the machine running in real time (Controller Diagnosis). Because the manual lists the monitored items on the same pages as the display screens, it doubles as a map of the machine’s electrical signals — every pilot pressure sensor, pump delivery and control pressure sensor, EC dial angle, hydraulic oil temperature, work mode switch, travel mode switch, and solenoid-valve feedback channel is named and unit-labelled.

Fault Code Library and Controller Coverage

The Section 4 fault-code tables are where this manual earns its place in a workshop. Each entry pairs a numeric fault code (for example 11000-2, 11101-3, 11200-4, 11301-3, 11400-2, 14000-2, 14100-2, 13308-2 and many more) with its trouble description, the cause, the control functions affected, the symptoms the operator will notice, and the Dr.ZX remedy — typically Retry B, a harness check, or a component replacement. Codes are grouped by controller (MC, ECM, ICF, satellite terminal, monitor unit) and split into two distinct ranges so the ZX160-3 to ZX330-3 class and the ZX450-3 to ZX850-3 class each get their own coverage.

Adjustment Data and Attachment Configuration

The adjustment-data chapters give the actual numbers to enter through Dr.ZX, per excavator class — minimum adjustment step, adjustable range, standard adjustment, and unit for engine-speed offsets, pump PQ torque, solenoid-valve output pressures, boom cylinder bottom pressure over balance, and the ATT speed-increase down waiting time. Attachment parameter tables then cover ATT1 through ATT5 with ATT Type, ATT Number, P1 and P2 max swash angle, engine speed increase/decrease, secondary pilot relief, selector valve, accumulator, and 2-speed selection — the exact settings required to configure a breaker, pulverizer, crusher, or vibrating hammer through the monitor unit’s Work Mode screen.

IMAGES PREVIEW

With this Hitachi ZAXIS ZX160-3 to ZX850-3 Excavator Dr.ZX Diagnostic Operation Manual on hand, a technician can safely navigate the Dr.ZX menus, run Self-Diagnostic Results and Controller Diagnosis on the correct machine class, adjust engine speed and pump delivery to the standard values listed in the tables, program attachment parameters, upload and download ECM data, write injector ID codes when a cylinder injector is swapped, and clear the fault codes that only Dr.ZX can read. Getting the correct procedure and the correct values matters — a wrong adjustment entry or a missed harness check can leave the machine in a derated state or cause a repeat failure. The manual is delivered as an instant PDF download: no shipping, no waiting, viewable on any device, and printable so a working copy can stay in the cab or on the bench.
