Front-Panel Access Levels
The relay front panel typically operates at Access Level 1 and allows any user to
view relay measurements and settings. Some activities such as editing settings and
controlling output contacts are restricted to those relay operators who know the relay
Access Level 2 password or can assert the ACCESS2 input (factory programmed to
input IN4). In the figures that follow, restricted activities are marked with the padlock
symbol shown in Figure 5.5.
