Operator Interface
153378
2–9
Standard Display
The Standard Display provides the following information:
•
First Line - System Status (ID 1)
•
Second Line - Inverter Status (ID 4)
•
Third Line - PV Status (ID 13)
•
Fourth Line - Goal State (ID 2)
Menu Structure
The operator interface consists of three levels:
•
R
EAD
Menu
- operation information provided
to
the user
from
the GT100.
The Read Menu consists of all operational values, the date and time. These
can be viewed any time the GT100 has control power.
•
W
RITE
Menu
- operational parameters provided
to
the GT100
from
the user.
The Write Menu consists of a goal state sub-menu, and all system
configurable parameters. The Write Menu can be viewed any time the GT100
has control power. However, modifying the parameters requires a password
that may only be altered by trained service technicians. Specifically,
parameters relating to utility protection setpoints should not be modified.
•
Data Logging
- the collection of specific parameters values over a period of
time. The data logging feature is only available if using the GT View GUI.
See the list of stored parameters on page 1–19.
Information reported back to the user (R
EAD
Menu) occurs at the VFD above the
Universal Front Panel Control Unit (UFCU) and (if used) at the computer running
the GT View GUI monitoring program. Making changes to the parameters within
the Write Menu is done with the UFCU keypad or the GUI software program and
requires a password.
Upon system powerup, the operator interface VFD will display the system
operating state on the first line. The inverter’s state of operation will be reported
on the second line. The PV Array’s state of operation will be reported on the third
line. The Goal target will be reported on the fourth line.
Important:
Specific grid-interface parameters within the W
RITE
Menu have been set in
the factory to the limits mandated by the UL 1741. Any changes to these setpoints should
be agreed upon by the local utility and the equipment owner.
Important:
While in the W
RITE
Menu, the operator interface display will reset itself to
the standard display if there is no input for more than 2 minutes.
