Figure 20 : Configuration - System menu
1)
Analog output
Two modes are available. The
Hold
mode maintains the 4-20 mA outputs
even if a new cycle is started. The
Track
mode ensures analogue outputs
always track input gas values.
2)
mA Failure Mode
In the case of a system status alarm, this control sets all the 4-20 mA outputs
below 4mA if
LOW
is selected and higher than 20 mA if
HIGH
is selected.
Selecting
OFF
will disable this function and the 4-20 mA outputs reflect
signal values as in normal operation.
