Screen Security Levels

The following table lists all screen and their base security
levels, see Table 11-1. Most screens have more than
one security level. The base security level gives the user
access to the setpoints that can change the performance
of the compressor. The secondary security level is
typically level 3 and is reserved for those setpoints that
require a high level of care and knowledge of the system
to make changes safely without damaging the system.
