The STS has a front touchscreen display that can display the following information:
• A dynamic one-line mimic display, showing the active source-to-output path, bypass, and measurements
(See
Figure 41 ).
• Setup and configuration settings
• Administrative and operational controls
• Alarm Log and Event Log
• AC wave form capture for transfer events or displaying the current wave structure
• Digital and Analog Points (Modbus registers)
• Voltage and current measurements for input sources and output load
• Harmonics for both voltage and current
• Load trending

• The Voice Unit annunciates alarms ("Static switch, new alarm") and cleared alarms at the unit and provides
operator cautions ("You are not authorized for this function").
• The Help function provides both text and voice-over instructions to guide operators through transfer tasks
for going to Bypass Mode and returning from Bypass to Normal Mode. The instructions are context-
specific, providing information for transfers appropriate to the current STS source-to-output connections.

The TFA STS is designed for mission-critical environments and has security features appropriate to that
environment:
• The administrator assigns each user a unique Personal Identification Number (PIN) associated with an
access level, such as administrator or operator, determining what actions the user can perform.
• A PIN and password are required to login.
• No changes to system parameters or STS operation can be made through the touchscreen Monitor
without a valid user login, and no changes at all can be made remotely via web access.
• Only one user can be logged in at a time. The Event Log records and time-stamps the user’s login,
changes to parameters or actions while the user is logged in, and the user’s logout.
• A key is required to open doors, controlling access to the MCSWs and components. Key access is also
required for the ROI.
• When an STS front door is opened, the unit alarms and the alarm is logged into the Event Log.
