Related to WP 7881, modified and recompiled the PSL ISS model, to change the name of a filter bank from PSL-ISS_SECONDLOOP_REFERENCE_DIFFRACTION_CAL to PSL-ISS_SECONDLOOP_REFERENCE_DFR_CAL
Modified accordingly the MEDM screen in /opt/rtcds/userapps/trunk/psl/common/medm/ISS/PSL_CUST_SECONDLOOP_SLOWOFFSET.adl
After today's maintenance and restart of the ISS model, the second loop is no more working at powers above ~10 W. It's fine to engage the second loop at 2 W, and to increase the power to 10 W. Above that, the loop drives the diffracted power very high.
It's not clear if the problem is to be traced to some configuration parameter in the ISS model, or to the fact that the diffracted power is now larger (2.4% instead of 1.4%).
More dedicated time is needed to investigate the problem.
