1. Power On - Lights when supply voltage is applied.This light flashes during self diagnostics start up.
2. Battery - Lights when the BX116 is powered by the standby battery.When flashing the standby battery has low charge.
3. Fault - Indicates a short circuit, sensor fault, loss of signal or incorrect connection of the sensor.
4. Test/Reset - When pressed checks the sequence and function of the BX116 / Press this to reset the detector after an
alarm or sensor fault condition
5. Zone 1 Indication - These L.E.D.'s represent the Zone 1 sensors and flash when a sensor is connected.
6. PPM L.E.D. - This lights when the jumper switch for display data is set to read in parts per million (PPM).
7. Display - Shows the current reading of gas concentration for the current sensor displayed.
8. Pre-Alarm (Zone 1) - 8% L.E.L. concentration of gas detected in Zone 1. Pre-alarm relay actuated.
9. Main Alarm (Zone 1) - 20% L.E.L. concentration of gas detected in Zone 1. Main alarm relay actuated.
10. Pre-Alarm (Zone 2) - 8% L.E.L. concentration of gas detected in Zone 2. Pre-alarm relay actuated.
11. Main Alarm (Zone 2) - 20% L.E.L. concentration of gas detected in Zone 2. Main alarm relay actuated.
12. % LEL L.E.D. - This lights when the jumper switch for display data is set to read in lower explosive limit (LEL).
13. Zone 2 Indication - These L.E.D.'s represent the Zone 2 sensors and flash when a sensor is connected.
14. No. of Sensors Switches - DIP switches allowing you to select how many sensors can be attached to the BX116.
15. Display Data Jumper - Allows you to select (via a jumper) whether the display reads in PPM or LEL.
16. Alarm Threshold Selector - Allows you to change the threshold at which the unit goes into alarm.
17. Sensor Selector Switches - Determines which sensors are currently working. MUST BE OFF TO ACTIVATE SENSOR.
18. Memory Switches - Determines whether or not the unit automatically resets after the gas concentration levels drop.
19. Sensor Connection Plug - Connection for the incoming return cable from the sensor.
20. Sensor Power Supply - Connections to power the sensors.
21. Relays - Connections for the relay outputs and fault relay.
22. Power Supply - Incoming power supply.
