Alarm A, B and C Menus
The screens for viewing alarm thresholds are combined in this manual. There will be either two or three levels, depending on transmitter type.
If present, separate “MIN” and “MAX”levels permit manual control of the hysteresis of each alarm. Normally, the “MAX” level is set greater than “MIN.” However, alarms can be made to trigger on falling concentration (as with oxygen) by setting the “MAX” threshold smaller than the “MIN” threshold.
With certain transmitters, only one threshold will be displayed.
Additionally, with certain transmitters, the alarm thresholds are read- only at the controller. These thresholds can be set only at the transmitter.
These are typical screens:
Typical screen for viewing alarms A or B on XCD and XNX transmitters
Typical screen for viewing or changing alarm A, B, or C thresholds on other transmitters.
