Action/Troubleshooting
+5V H AMP GAS
SUPPLY XDUCERS
Reboot system. If problem continues:
1. With system in Standby, disconnect all gas supply pressure transducers from ABS Filter board.
2. Reboot system.
• If problem continues, replace the ACB.
• If error is no longer present, set system to Standby and reconnect one pressure transducer at a time.
3. Reboot system and check for error with each transducer connected. Replace the transducer that
causes the error to appear.
12 HR TEST
At next available time, move the system switch from the On position to the Off position, then back to the
On position.
ACB 4.096V ADC REF
Reboot System. If problem continues, replace the ACB.
ACB ADC FAIL
Reboot System. If problem continues, replace the ACB.
