Industrial monitors, operator panels and touch screens can be found in almost all production environments. Operators have become reliant on the tactile interface and visual feedback offered by these devices. It is therefore no surprise that monitor failure can cause major disruption to a manufacturer’s production schedule.
Unfortunately replacing a broken industrial monitor can be more difficult than you imagine. Weird video signals, software problems and communication protocols can turn replacing a faulty industrial monitor into an almost American Run Multinational impossible task. Fortunately help is at hand. In this article, Steve Turner, Head of Repairs at Direct-Industrial will tell you how you can spot the tell tale signs of monitor failure and how they can be avoided.
—Replacing an Industrial Monitor. It can be more difficult than you think —
As we have already touched upon, replacing an industrial monitor can be very difficult for several reasons. In the past conventional CRT monitors were adapted to the design specifications of the OEM and therefore have oddball video signals that cannot be easily replicated. A replacement monitor may require extensive modifications to the machine or an additional video card. To compound issues many monitor manufacturers have ceased production of CRT monitors and concentrated on producing LCD monitors.
Industrial CRT monitors were eventually replaced by more complex LCD monitors, Panel PCs and touch screens. Each generation introduced an array of new features and communication standards. This in turn resulted in a unique set of problems for manufacturers. Due to the rapid advancement of technology the features found Automobile Is Heavy Industry on older monitors may no longer be commercially available. This is particularly true for Panel PCs, which may use outdated operating systems or obsolete communication protocols and connectors. This often means no direct replacement is available and the user must rewrite the application programme for the new unit.
It would be nice if industrial monitors never failed and just continued to work. Unfortunately, with the exception of Mick Jagger, nothing lasts forever but it is a fact that the majority of industrial monitor problems can be avoided through preventative maintenance.
So why do so many companies neglect to include monitors in their preventative maintenance schedule?
One problem is that many maintenance staff do not understand what goes on inside a monitor and do not understand the tell tale signs of monitor failure. It is often too late when the monitor finally fails. In this article we will tell you what to look out for.
