5.2 Maintenance intervals and wearing parts
All devices are designed for 24/7 use. The resulting load places the highest demands on the com-
ponents and materials used.
To ensure reliable operation under these demanding operating conditions in the long term, pre-
ventive replacement of the following components is recommended:
Component replacement after Notes
Mass storage 30,000 operating hours
*1
data backup before replacement is recommended
Panel 30,000 operating hours No pretreatment required
*1
The lifetime of flash memory depends on numerous external factors. High ambient temperatures, a high
utilization of the memory capacity as well as numerous write operations, especially of many smaller files,
puts additional stress on the memory. Depending on your device environment and the relevance of your
locally stored data, other intervals may therefore make sense.
The device does not require any consumables for operation.
5.3 Malfunctions and alarm signals
If any mechanical damage to the housing, display and connection cables is detected, the device
must be taken out of operation. In this case, the device must be checked by service personnel.
Operation with damaged components can lead to further defects as well as data loss.
In the following cases, restart the device and check the device environment for strong sources of
EMC interference and for non-compliance with the specified minimum distances from sources of
interference provided in Section 3.3 :
• Interference signals in the image
• Sporadic, brief intermittent image display
• Keypad triggers without user input
In the following cases, disconnect the device from the mains immediately and contact the manu-
facturer or authorized service technicians:
• Unusual emission of odor or smoke
• Strong heating of the device
• Damage to the power cable or plug
• Malfunctions of the device, although the operating instructions were followed
• Clear changes in the behavior of the device indicating the need for maintenance
• Mechanical damage to the device or the front pane (e.g. due to falling).
• Unusual noises emanating from the device during operation
There is no alarm system integrated in the device.
