Maintenance
Notice | |
Use of incorrect spare parts The use of spare parts not ordered from Beckhoff Service can lead to unsafe and faulty operation.
|
Beckhoff devices are manufactured from components of the highest quality and robustness. They are selected and tested for best interoperability, long-term availability and reliable function under the specified environmental conditions.
Nevertheless, some components of the devices may be subject to a limited service life if they are operated under certain conditions, such as at increased ambient temperatures during operation or during storage or during long periods of storage out of operation.
Beckhoff therefore recommends replacing some of the components of the devices after the time after which predictions of the remaining service life of such components can no longer be reliably calculated.
These are the following components:
- Storage medium
- Battery
The following table provides recommendations for the regular, precautionary replacement of the device components:
Component | Recommendation for replacement intervals (years) |
|---|---|
UPS battery pack | 5 years |
2.5-inch hard disk | 5 years or after 20,000 operating hours at more than 40 °C or after 30,000 operating hours at less than 40 °C |
3.5-inch hard disk | 5 years, irrespective of the operating hours |
Fan | 7 years |
Compact Flash, CFast or SSD | 10 years |
Motherboard battery | 5 years |
Beckhoff is excluded from liability in the event of possible damage occurring during maintenance work. In order to avoid damage caused by electrostatic discharge when replacing device components, protective measures are recommended. Below are some suggestions.
ESD protection
Notice | |
Electrostatic discharge The replacement of device components without ESD protection can lead to functional impairment and destruction of the device.
|
When working on electronic devices, there is a risk of damage due to ESD (electrostatic discharge), which can impair the function or destroy the device.
Protect the device and create an ESD-protected environment in which existing electrostatic charges are safely discharged to ground and charging is prevented.
An ESD-protected environment can best be created by setting up ESD protection zones. The following measures serve this purpose:
- ESD-compliant floors with sufficient conductivity to the reference potential PE;
- ESD-compatible work surfaces such as tables and shelves;
- Wrist grounding strap, especially for sedentary activities;
- grounded and electrostatically dissipating equipment and operating materials (e.g. tools) within the ESD protection zone.
If it is not possible to create an ESD protection zone, you can still protect the device against ESD damage. For example, the following measures can be used:
- Use conductive mats connected to the ground potential as underlays.
- Dissipate possible charges from your own body by touching grounded metal (e.g. control cabinet door).
- Wear a wrist grounding strap.
- Only remove new electronic components from the ESD packaging (tinted plastic bag) after putting on the wrist grounding strap.
- Do not walk around with electronic components in your hand if they are not in ESD packaging.
Access to exchangeable device components
Access is gained to the battery (1) and storage medium (2) from the back of the panel PC. The components are located behind a cover. To gain access to the device components, loosen the four M3x8 screws and remove the cover (see Fig. 12).
