Introduction
The SIMPRO-100 Relay front panel gives you
access to most of the information that the relay
measures and stores. You can also use
front-panel controls to start or stop the motor,
pulse output contacts, and view or modify relay
settings.
All of the front-panel functions are accessible
using the six-button keypad and vacuum
fluorescent display. Use the keypad, shown in
Figure 5.4, to maneuver within the front-panel
menu structure, described in detail throughout the
remainder of this section. Table 5.2 describes the
function of each front-panel button.

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.
