Heidelberg printing presses, including Speedmaster, Printmaster and GTO machines, carry many machine-specific control, drive and interface boards. Spares for older presses are often hard to source, which makes board repair the practical option.
Common faults
What usually fails on a unit like the CD-74
Industrial PCs, panel PCs and machine networking hardware fail mostly in power supplies, storage, fans and displays. Repairing the original unit keeps the operating system, licences and machine software as they were.
Won't power up
A failed internal power supply or DC-DC converter, or a motherboard power fault.
Storage and boot failures
Worn-out hard disks, SSDs or CF cards. The data can sometimes be recovered and the system cloned to new storage.
Overheating and fan failure
Clogged filters and failed fans cause shutdowns and slow, unstable operation.
Display and touch faults on panel PCs
Backlight, LCD or touch screen failures, as on operator panels.
Network and interface faults
Dead Ethernet ports, fieldbus cards or serial interfaces, and failed industrial switches.
Communication
Communication faults can be in the module, the cable or the network configuration. The module is tested on a live link after repair; the cabling and terminations at site are worth checking too.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Note any BIOS beeps, error messages or LED codes.
- Check fans and filters.
- Back up data and licences if the unit still boots.
Leave to a specialist
- Motherboard and power-supply repair.
- Cloning or recovering the system disk.
- Moving software licences to new hardware.
