Bubbler Air Monitoring System (BAMS)
BAMS
Product Status: CLASSIC / LIMITED RELEASE
Bubbler Air Monitoring Systems
Product Overview
The BAMS is a solid-state controller that monitors and alternates two air supplies to keep bubbler airflow continuous. It displays airflow, indicates the status of each supply and the flow switch, and runs a self-test on demand. All adjustments and electrical and pneumatic connections are on the front panel.
The following control switches and status indicators are provided on the front panel:
- Air Supply Run (Green LED): on steady when air supply terminals are powered
- Air Supply Fail (Yellow LED): on flashing when no airflow is detected
- Air Flow (Green LED): on steady when airflow is detected
- No Air Flow (Red LED): on steady when no airflow is detected
- Flow Switch Failed (Red LED): on steady when the internal differential pressure switch does not respond to changes in airflow
- Alternate Push Button Force air supply alternation
- Reset / Test Push Button Push to reset alarm or initiate system self test sequence
- Manual / Automatic Mode Selector (Four Position Dip Switch)
- Dip Switch No. 1 selects air supply no.1 to run continuously when in the right position.
- Dip Switch No. 2 selects air supply no.2 to run continuously when in the right position.
- Note: Automatic alternation will occur when dip switch nos.1 and 2 are in the same position.
- Dip Switch No. 3 selects automatic alternation time, unbalanced (left), balanced (right). Unbalanced alternation time calls for air supply no.1 to run for four hours and air supply no. 2 to run for one hour. Balanced alternation time calls for each air supply to run for four hours when called to run. A flowmeter is provided for visual indication of the monitored system airflow.
The Bubbler Air Monitoring System provides three form A dry contacts for remote monitoring:
- Air Supply Warning: closes to indicate that one air supply has failed
- Air Supply Failed: closes to indicate that both air supplies have failed
- Flow Switch Failed: closes to indicate that the flow switch failed to open or close when required
