mA output
percentage output for VFDs
Channel:
Choose the channel number that the analog output will
monitor.
Fault:
Output this value if the channel goes into fault.
Press SAVE to save the changes.
• AVERAGE is the average gas concentration reading that is calculated by looking at all
the channels assigned to each chosen priority level. All channels in the first priority
level are averaged, then all the channels in the next priority level are averaged, etc.
The priority level that has the highest average is the value that is used to drive the
analog output.
mA output
percentage output for VFDs
Priority:
Add, change or remove the priority levels this analog output will
look at
Fault:
Output this value if any of the channels in the priorities selected
go into fault.
Digital:
Output this value if one or more of the channels in the selected
priorities has a time of day priority engaged.
Normal:
Output this value if the channels in the selected priorites are
reporting everything is normal but you want the the analog output to
remain on.
Press SAVE to save the changes.
NOTE:
The AVERAGE and the PEAK are based on the value of the channel relative to its
range. Meaning be aware for example, that an Oxygen sensor has a range of 0 - 25% vol and
a normal reading is 20.9%, which is 83% of the sensor’s range. CO has a range of 0 - 200 ppm
and the low alarm is set at 30 ppm, which is 15% of the sensor’s range. If you were to group
