7 Maintenance
7.1 General
In principle, the ILR system is maintenance-free. When correctly installed it operates for many years
without any problems.
7.2 Precautionary Maintenance
Regular checking of all ports and cables belonging to the system is recommended. Unstable
connections could lead to damage and malfunctions of the system and therefore should be repaired
as soon as possible.
A Brief Checklist
• Are all casing intact?
• Are all cables intact?
• Are all connectors intact?
• Are all connectors securely fastened?
• Are all screws still tight?
• Is there suddenly a malfunction at a specific unit?
7.3 Exchanging an i-PORT within the i-BUS daisy chain
• Exchange only one unit after another, not several in one step.
• Exchange the reader with one of the same type.
• The i-PORT automatically scans the i-BUS every 10 seconds, so it will automatically recognize the
exchanged device.
7.4 Firmware Update
The firmware is stored in a FLASH memory and can be updated if needed.
