8 Diagnostic functions
With the error case "sensor-band gap exceeded" occurring, the RS422
driver's output will be switched high-impedance (signals A, /A, B, /B)
(only with LD version)!
Various diagnostic functions have been integrated into MSAC501.
A two-colour LED signals the actual error states. The states are differenti-
ated via the LED's colour and blinking rates. The signal is repeated after a
600 ms pause.
Error state LED Blinking rate
1. Sensor-band gap red 1x
2. Plausibility absolute value red 2x
3. Speed check (v >5 m/s) red 4x
4. Sensor-tape alignment green 1x
5. Verify error EEPROM green 2x
6. Checksum error EEPROM green 4x
7. Read/write error EEPROM green 8x
If several error states occur at the same time, the relevant blinking sig-
nals will be added to form a sequence (e. g., red LED blinks 5x -> error sta-
tes 1 + 3).
