Communication Features and Methods
The GT100 provides three types of information to the user:
•
system status and/or fault information,
•
data logging information, and
•
oscillography.
System status and fault information can be accessed using the Universal Front Panel
Control Unit (UFCU), via an RS232 connection to a PC or via an RS485/Modbus
connection to a remote monitoring system. Data logging and oscillography is available
via the RS232 or the RS485/Modbus connection.
The GT100 communicates system status information to the user using the following
methods.
•
The Front Panel Control Unit (UFCU) Display
•
PC Connection (Remote) - GT View Graphic User Interface (GUI) Software
required (may require additional hardware)
•
External Monitoring - (Optional) via an RS485/Modbus connection for remote plant
monitoring.
System Status and Fault Reporting
Basic system status and all fault conditions rising from within the GT100
are reported to
the UFCU. The 4-line VFD will display a hexadecimal value and a brief text description
of the fault. Additionally, the CCU2 stores the time and details of all faults in non-
volatile memory for later retrieval.
The fault value is also made available to the GT View Graphic User Interface (GUI) via
the RS485/Modbus protocol and will include a more extensive description of the fault.
The UFCU keypad is located on the left door to manipulate and view system operation
and status. The keypad is comprised of 20 membrane switch keys that provide a means
to navigate through the menus and alter user-settable settings.
See the GT100 Grid-Tied Photovoltaic Inverter Operation and Maintenance Manual
