Technical Information
Protect
The protect function is useful to avoid damages in the ion pump due to the
overcurrent.
If this function is enabled, the controller waits 10 seconds from the HV ON, then it
begins to check the current provided. If the current exceeds the threshold in the
following table, the HV channel turns off and the controller gives the "Protect Error".
This kind of error is not a controller error but it is only a warning, informing that the
HV channel is turned off because the protect current threshold was exceeded.
