Sensor Configuration
3. Click the Save to Device button located at the bottom of the
window.
4. The detector LCD automatically updates. The gas type and
sensor readings no longer display on the LCD for the applicable
sensor.
5. Enable the sensor as soon as possible. If the sensor is
damaged, replace it immediately. Refer to Replacing a Sensor or
Sensor Filter.
Calibration Gas Concentration
a Caution
The gas concentration value entered in Fleet Manager II must
match the gas concentration value on the gas cylinder.
1. Refer to the following list of recommended gas mixtures:
• CO: 100 ppm balance N
2
•H
2
S: 25 ppm balance N
2
• LEL: 50% LEL or 2.5% by vol. methane balance air
•O
2
: 20.9% balanced with N
2
2. Select/enter the gas concentration value in the Calibration Gas
field of the applicable sensor.
Calibration Interval
a Caution
BW recommends that the sensors be calibrated once every
180 days (6 months).
Define how often a sensor should be calibrated in the Calibration
Interval field. A different calibration interval can be defined for each
sensor.
1. Enter the value (0-365 days) for each sensor.
2. Enter 0 to disable the calibration interval option. Entering zero
automatically deactivates the Force Calibration When Overdue
user option.
The detector is shipped with the factory default set to 180 days.
Bump Interval
Define how often a bump check should be performed for each sensor in
the Bump Interval field. A different bump interval can be defined for
each sensor.
1. Enter the value (0-365 days) for each sensor.
2. Enter 0 to disable the Bump Interval option. Entering 0
automatically disables the Force Bump When Overdue option.
The detector is shipped with the factory default set to 0 days.
Note
BW recommends to bump test the sensors before each day’s
use to confirm their ability to respond to gas by exposing the
detector to a gas concentration that exceeds the alarm setpoints.
Verify that the audible and visual alarms activate. Calibrate if the
readings are not within the specified limits.
