Fault Finding
| Operational Fault Symptom |
Fault Description |
Fault Code(s) Reported and Logged at the Router |
Suggested Action |
| Loss of functionality of a single ANS |
Remote I/O unit analogue channel fault (open or short) |
REMXX/AINYY ANALOGUE I/P XX=Remote I/O Unit Address YY=Analogue Input Channel |
- Check wiring of the ANS on the specified analogue input channel.
- Check the ANS on the specified analogue input channel, and replace it if necessary. The ANS external and internal LEDs provide additional indication.
- Replace the BMB02 Remote I/O Unit.

ANS Front Panel LEDs’ Fault Reporting
HIGH and LOW LED Indication
| Operational Fault Symptom |
External LED Indication |
Suggested Action |
| Total loss of functionality of an ANS Sensor |
- HIGH: OFF (ANS Range N/A)
- LOW: OFF (ANS Range N/A)
|
- Check power supply to the ANS.
- Check wiring between the ANS and the BMB02 analogue input
- Check connection of sense resistor at BMB02
- Check BMB01 unit. If faulty, replace BMB02
|
| Incorrect ANS operation (too loud or too quiet). |
- High: ON (High Range 65dBA - 95dBA)
- Low: OFF (High Range 65dBA - 95dBA)
- High: OFF (Low Range 55dBA - 85dBA)
- Low: ON (Low Range 55dBA - 85dBA)
|
- Confirm that the LEDs indicate the expected ANS range set-up.
- Check the brightness of the LED that is turned on. If the LED brightness decreases with increase in the ambient noise, then the ANS sensor is operating correctly. You may need to re-configure the ANS sensor to the required ANS range.
- Check the ANS range set at the Router/VIPA unit. If both the Router and the ANS Sensor have not been set to the same ANS range, then set either the Router/VIPA unit to the required ANS range.

ANS Internal LED's Fault Finding
| Operational Fault Symptom |
Internal LED Indication |
Suggested Action |
| Total loss of functionality of an ANS Sensor |
- PWR LED (green) is OFF: Power is not present
|
- Check power supply to the ANS.
- Check wiring between the ANS and the BMB02 analogue input.
- Check connection of sense resistor at BMB02.
- Check BMB02 unit. If faulty, replace BMB02.
|
| Total loss of functionality of an ANS Sensor, though the ANS Sensor still appears to be functional |
- MIC FAULT LED (amber) is ON: Microphone capsule open or short circuit fault.
|
- Check continuity of microphone capsule and associated wiring. If faulty, replace ANS sensor.

You can also monitor the Router input thresholds using a multimeter:

ANS power supply comes from the Vipedia-12's "Onboard GPIO" or from a BMB01/BMB02.
