Abb. 44: Jumper settings
The connector J1 is for selecting different options for the induction generator
control. By default, one jumper is set in the factory at the position “current control”
connecting the pins B1-B2 and a second jumper is set to connect B3-B4 for “On
board power adjustment”.
The connector J3 is for selecting options for the oxygen flow. The factory setting of
the jumper is for “External flow enable”, by connecting the pins A1-A2. In this case,
the microcontroller board can start and stop the flow enabling gas saving mode.
When moving the jumper to B1-B2 for “On board flow enable”, the flow will start
and stop with the analysis begin and the analysis end, in other words, there is flow
only during analysis. This can be interesting for older analyzers without gas saving
function in their software, when they are used in automations running analyses
only once in a while with long and regular idling period between analyses, for
example 15 minutes.
At position “Continuous flow” when the jumper connects B3-B4, there is continuous
flow as long as the mains power switch is set to position 2. The continuous flow
position is useful in case of looking to solve flow problems, because the flow is
always enabled.
