When performing a bump test or calibration, gas must be applied in a specific order to prevent gas conflicts that can damage the detector's sensor(s).

Note

Ensure that the gas inlets are configured correctly. Refer to Inlet Select.

The gas conflicts screen automatically displays if a gas conflict occurs when a bump check or calibration is initiated.

There are two types of gas conflicts:

• Conflicts: More than one inlet is configured for a specific gas type.

Example: Inlet 2 is configured for SO2 and inlet 3 is configured for the 3-gas SO2 mix.

• Not Found: The base station is unable to locate the required gas type for a specific sensor on the detector.

The base station displays additional information regarding the

• number of gas conflicts,
• number of gases not found,
• docking module (e.g., Bay 1),
• detector gas type(s),
• inlet, and
• inlet gas type(s).

If a gas conflict is detected by the base station, the gas conflicts screen automatically displays.

Refer to the following sections, Conflicts and Not Found. Before proceeding to resolve gas conflicts, refer to the following section Abort Option.

Abort Option

The Abort option is located in the gas conflicts screen. Selecting Abort exits the gas conflict function and the base station returns to normal operation. A bump test or calibration will not be performed.

Proceed to the user options menu and select the Inlet Setup option.
To abort a gas conflict, complete the following:

1. From the gas conflicts screen, press more.

2. The conflicts/not found screen displays.

3. Press or to scroll to the Abort Test option.

4. When displays beside Abort Test, press sel or press OK. The base station automatically exits the gas conflict and returns to the normal operation.

Conflicts

If a conflict occurs, it must be resolved to continue the bump test or calibration. The user may select the gas inlet or accept the gas inlet suggested by the base station.
Press cancel to exit the gas conflict screen and return to normal operation. A bump test or calibration will not be performed.

Base Station Selects the Gas Inlet

To resolve a conflict automatically, complete the following steps.

1. Press more in the gas conflicts screen to access the gas type/inlet screen to view which gas is configured for more than one inlet.

The gases display.

displays on the far right side on the row of the gas that is setup for more than one inlet. The also indicates the inlet that the base station has selected as the optimum inlet.

2. Press OK to accept the inlet that is selected and automatically resume the bump test or calibration.

Note

If sel is not pressed within 30 seconds, the base station automatically defaults to the inlet it has selected.

User Selects Gas Inlet

1. Press more in the gas conflicts screen to access the gas type/inlet screen to view which gas is configured for more than one inlet.

The gases display.

2. Press or to move to the gas that is in conflict.

3. Press sel to access the inlet field. The automatically displays on the left side of the inlet.

4. Press or to scroll to the desired inlet (1-5).

5. When the required inlet value displays, press sel to confirm the selection and exit the field. The no longer displays to the right of the inlet indicating the conflict has been resolved.

Note

If sel is not pressed within 30 seconds, the base station automatically defaults to the inlet it has selected.

Unsuccessful Conflict Resolution: If the conflict is not resolved by selecting a different inlet, refer to the following:

• Ensure that the selected inlet is correct.
• Ensure the gas cylinder that is attached to the selected inlet is correct.
• Press OK to accept the base station's default selection

Not Found

If a value of 1 or more displays before Not Found, the base station is unable to locate the required gas type for a specific sensor on the detector.

Press cancel to exit the gas conflict screen and return to normal operation. A bump test or calibration will not be performed.

To define the gas inlets, complete the following.
1. Press more in the gas conflicts screen to access the gas type/inlet screen to view which gas type(s) cannot be found.

The gases display.

displays on the far right side of the gas that cannot be found. The base station automatically defaults to the Purge inlet.

2. Press OK to accept the default Purge inlet.
or
Press sel to select a different inlet.

Note

For gases not found: If sel is not pressed within 30 seconds, the base station automatically defaults to the Purge inlet.

3. If required, repeat steps #1-2 for any additional gases not found and confirm the following:

• Ensure that the selected inlet is correct.
• Ensure that the gas cylinder attached to the selected inlet is correct.
• Press OK to accept the base station's default selection.
