Chapter 3: Operation
Selftest (BITE) |
|
|
The selftest checks: | all operating voltages, | |
| host processor, | |
| memory, | |
| DSP processor. |
In case of an error the determined functional unit will be indicated with a "FAIL". If the internal operating voltages totally fail or if they deviate extraordinary from the tolerances a selftest cannot be carried out.
Error:
In case of an error the unit generally should be switched off and after a few seconds it schould be switched on again. If the error message is displayed again it is recommended to send the unit to the service, corresponding to Chapter 5 (Service).
Battery operation
The battery operation of the VOR/ILS Analyzer EVS200 is an optional component. It is always pos- sible to retrofit the unit with this mode.
The unit automatically goes into battery operation when the external power supply (DC/AC) is switched or cut off. The battery operation is indicated on the display by the battery symbol (
) in each mode.
The operation time is >100 minutes (max. brightness) or >150 minutes (at average brightness) with a completely charged battery.
The charging state can be seen from the battery symbol on the display:
100% battery power
approx. 75 to 25% battery power
flashing symbol, approx. only 5 minutes operation is ensured. Battery must be charged.
The battery will be charged on AC operation (as well during operation as on "STANDBY") and should take at least 12 hours (charging time).
After 4 to 5 years or when defect the battery must be
changed according to Chapter 5 "Service".
