3. MAINTENANCE
This section provides the information required for the proper maintenance of your EDSS. We
strongly recommend that you keep written records of every fault and repair. Note, on each
occasion, the serial number of the defective assembly (ID plate on back of each assembly).
Your written records will be a good fault finding tool for future troubleshooting.
3.1. TEST EQUIPMENT
With the exception of the database transfers to a PTU or USB key requiring a PC, no special
test equipment is needed to perform maintenance on the system other than the tools usually
found at a technician’s bench.
3.2. CLEANING
3.2.1. CLEANING
The different components of the EDSS can be cleaned with a moist towel. We recommend
the use of a mild soap for the casing and a domestic glass cleaner for the acrylic window of
the outside Rear Sign. Do not use highly concentrated solvents that would damage the
acrylic window.
3.2.2. FUSE REPLACEMENT
● Turn off sign power supply.
● Open the Back Plate of the Front Destination Sign.
● Locate the faulty fuse and replace it with a new one of the same specifications.
(See Figure 18: Fuse Definition).
