Electronic Testing & Diagnostics

Fault diagnosis and recorded functional checks, with workshop testing clearly separated from tests that need your machine.

Overview

Service introduction

Before deciding to repair or replace, you need to know what has failed. Every job starts with inspection and fault assessment.

We diagnose power rails, input/output stages, driver circuits and cooling components, record the checks performed, and are clear about what can be verified in the workshop and what requires the customer's machine, program or production setup.

Technical capabilities

  • Inspection and fault assessment of boards and modules
  • Power-rail, input/output stage and driver-circuit diagnosis
  • Cooling-component checks
  • Power, output, display or functional checks applicable to the unit
  • Repair records and technical handover

Units from our testing and diagnostics records

Seven units from our records ride an indexing conveyor. Under the gantry each one runs its record: the reading or finding first, then the repair, then only the checks that were actually done, shown on a readout card. The plate names the unit and the result.

Industrial control board

Components, copper traces and signal paths: the level at which we diagnose and repair boards.

Models drawn in code from the units in our test records and published dimensions, without logos or name plates; the touch monitor, stepping motor driver and relay board follow our own photos; the temperature controller is representative. Not photographs. Readings and checks shown are only those in each record.

Engineering process

Our workflow for this service

Start an inquiry
  1. STEP 01

    Understand

    Model, symptoms and required outcome.

  2. STEP 02

    Diagnose

    Inspect and assess the fault.

  3. STEP 03

    Agree

    Confirm scope and quotation.

  4. STEP 04

    Repair

    Carry out the approved work.

  5. STEP 05
