4.10 Scheduled maintenance
The CAN architecture of the DIAM3200 CCR controller of the OCEM Airfield Technology is designed to minimise
the number and variety of spare parts and to allow wide configurability of the options. OCEM Airfield Technology
offers software tools to perform quick parameter settings or diagnostics, without having to remove any parts.
Before carrying out any intervention on the device, cut off all external power sources and
place appropriate work-in-progress warnings on the systems.
Wait for the discharging time (at least 5 min) and check using appropriate instruments that
there are no residual energies before accessing the electrical equipment.
If present, use the CUT-OUT disconnector to secure the device during maintenance operations.
See the relevant technical documentation for more information.
In accordance with the suggestions contained in the document ICAO Airport Service Manual - Part 9: Airport
Maintenance Practices, or on the basis of what reported in the document FAA AC 150 5340-30, the devices
DIAM3200 must be subjected to regular maintenance.
In order to assure the proper functioning and the maximum duration of the operating lifetime of the device all the
checks and periodical audits must be carried out and, if necessary, the necessary corrective procedures must be
activated to restore and ensure operative safety levels foreseen by the standards.
Do not let running devices not properly maintained or fixtures presenting signs of damage
