2.6 Fault Isolating Flow Charts (Console Assembly)
Flowcharts for the isolation of faults on the console assembly (Monitor, PCIO
unit and Processor unit) are shown on page 20 to page 29.
Flowcharts 2, 3 and 4 cover the monitor picture faults. Flowcharts 5 to 10
cover the error messages that may appear which are relevant to the Console
assembly hardware.
The Flowcharts should be read in conjunction with the following notes.
Note: Before using the following fault finding flow charts visually check the
console modules to make sure there are no loose plugs or
connections.
Note: After checking the module connection status always check that the
configuration of all components on the system is correct by
accessing the Configuration tool, see Chapter 4, ‘Configuration’.
If faults cannot be rectified after reference to the console assembly fault
finding flowcharts you may need to contact the VisionMaster FT service
department to resolve the problem.
Prior to contacting the service department use Table 4 to help specify the
problem you may have with the console assembly.
