5.2.2 Visual Inspection
Inspect the Advant Controller and the I/O cabinets at regular intervals determined by
environmental factors such as vibration, high ambient temperatures, and so on.
5.2.3 Safety
Check that all screwed joints and connections within the cabinets are tightened effectively.
Ensure that wiring, circuit boards and other electrical components are undamaged.
Pay particular attention to overheating, damaged insulation or signs of wear.
5.2.4 Cleanliness
Remove dust and any other soil from the cabinet with a vacuum cleaner. Use a lint-free cloth,
dampened with methylated spirits to remove stubborn dirt.
5.2.5 Air Filter
The fan unit located beneath the controller subrack (Advant Controller 450) always includes an
air filter.
Wash the air filter included with the equipment in warm water with a mild detergent at regular
intervals determined by environmental conditions. Replace the filter after three such washings.
The new filter must be an approved spare part.
5.2.6 Backup Batteries
Replace the rechargeable battery package mounted inside the controller cabinet on the right-
hand side after every three years of service.
Also replace it after each complete discharge (the memory contents are lost), which introduces
the risk of battery cell damage. See
Section 5.5.10.7, Battery Exchange
.
5.2.7 Forced Cooling
The fan unit incorporates transducers which are activated by failure of the cooling system.
This condition is indicated in the data base (Station Element) and the system status display in
the central operator station.
5.3 Hardware Indicators
Most of the replaceable hardware modules are equipped with LED indicators.
•
A green LED indicating running.
•
A red LED indicating fault.
Some modules provide additional yellow LEDs for increased maintainability, for example send
and receive information on communication modules. The general meaning of the LED
indicators can be found in the module descriptions,
. The fault
finding instructions included in this
give further advice how to interpret
combinations of LED indications in different system configurations.
