Malfunctions in technical systems are always unpleasant. It becomes even more frustrating when the cause of the malfunction is not immediately found, leading to extended downtime. In such cases, quick action is needed, but an experienced electrician is not always available to promptly narrow down the fault through targeted measurements.
To assist you in these situations, we have developed a range of support tools to help you identify the cause of a malfunction more quickly.
Informative error messages directly on the display
Older industrial systems often show only an error code in the event of a malfunction, which can be difficult to interpret without the appropriate documentation. In many cases, the support of an electrician is required, who may have to troubleshoot without a wiring diagram in the worst-case scenario.
Our PLC controls solve this problem with an integrated display. Instead of a cryptic error code, you receive a clear description of the issue directly on the screen, enabling faster fault diagnosis.
Would you like to learn more about the different messages that can be displayed? Read our article No more cryptic error codes: Clear messages, quick solutions.
Smart sensors for efficient troubleshooting
In addition to informative error messages, using intelligent sensors can be a crucial step in speeding up the resolution of malfunctions. This is especially advantageous for larger dock lift tables equipped with plug-in guardrails.
Imagine your dock lift table has eight plug-in guardrails. An error message on the display indicates that the lift cannot be moved because one of the guardrail segments is not properly inserted. To avoid manually checking all eight guardrails, we use RFID sensors instead of simple roller lever switches. The RFID sensors identify the faulty guardrail directly on the PLC control display.
Alternatively, the affected sensor can be read via an NFC interface in the control area using a smartphone or tablet. This technology saves time and enables more precise fault diagnosis.
For a detailed guide on reading the NFC interface, read our article Quick guide to SRF diagnostics.
Convenient overview of all sensors and actuators
All larger, internally installed controls – such as in our goods lifts, dock lift tables or industrial work platforms – are now equipped with a WLAN router as standard.
In the event of a fault, you can securely (password-protected and encrypted) connect to the control system of our plant with any smartphone, tablet or laptop. The web interface displays all sensor states and the currently activated outputs of the programmable logic controller (PLC). This allows you to quickly determine which PLC input is not active, even though it should be. For a detailed guide on establishing the WLAN connection, refer to our article Establishing a WLAN connection.
An additional advantage: If our technician has access to the relevant laptop (e.g., via MS Teams), they can quickly assess the current system status and provide targeted support for troubleshooting – without the need for a time-consuming trip.
What you need to do to access the advanced features
You might be wondering what you need to do to benefit from our support features. The good news: In most cases, you don't need to do anything. As mentioned earlier, these functions are already standard in larger, internally installed control systems, allowing us to provide you with quick and effective support in case of a malfunction.
If you wish to use these advantages for a simpler scissor lift table, just give us a quick heads-up during the quotation phase. We will gladly plan the appropriate control system for you.
As always, if you have any questions, feel free to reach out to us.
