Looking at the inspection lines noticed that all the EXL signals were inverted (negative) and we were coding only the pole zero part of the signals.
Looking into the manual find out how to change polarity of the signals. Did that and now the signals look normal with normal gain change after polarity change.
EXL polarity is negative so Mesytech modules have to be set to use negative input signals.

PPT HV = 650 V
This is happening when the pre-amplifiers for EXL are not alimented.. When they are alimented the EXL sigal polarity is positive.. The gains and thresholds for Mesytech modules are below |
