GX9 ASD Installation and Operation Manual 31
Electronic Operator Interface
The GX9 ASD Electronic Operator Interface (EOI) is comprised of an LED screen, an LCD screen, two
LEDs, a rotary encoder, and five keys. These items are shown and described on pg. 33 .
EOI Operation
The EOI is the primary input/output device for the user. The EOI may be used to monitor system
functions, input data into the system, perform diagnostics, and view performance data (e.g., motor
frequency, bus voltage, torque, etc.).
The software used with the GX9 ASD is menu driven; thus, making it a select and click environment. The
operating parameters of a motor may be selected and viewed or changed using the
EOI (or via
communications).
Battery Backup
The EOI is equipped with a battery backup system. The function of the backup system is to retain the EOI
SRAM programming in the event of a power outage, or if an EOI removal and installation from one
system to another is required without the loss of programming.
Listed below are the items retained by the battery backup system:
Trip History ,
EOI Contrast ,
Real-Time Clock Information,
Monitored Items ,
Password and Lockouts Information,
Alarm Information,
Main Monitor Items,
Prohibited Items, and
Save User Settings Information (Parameter settings may be saved by the user).
The battery backup system must be activated by the installer or maintenance personnel to use the backup
function.
To activate the battery backup system, remove the Phillips screw from the front of the LED/LCD display
unit (see
Figure 20. on pg. 33 ). Remove the LED/LCD display unit from the ASD. From the circuit side of
the display unit, remove the jumper at J1 , pins 2 and 3 . Place the jumper at J1 , pins 1 and 2 . The battery
backup system is now configured for use.
The expected battery life cycle is four and a half years.
Note: The Battery backup system provides for memory retention only — it does not supply
power to the LED/LCD display or any other subsystems.
LED/LCD Screen Installation Note
When installing the LED/LCD display unit of the EOI, ensure that the left side of the display is inserted
first with the top and bottom catches (see Phillips screws at underside of display) securely in place. This
ensures the proper alignment and electrical connection of the CNX connector of the LED/LCD display
unit board. Gently hold the display in place while securing the Phillips mounting screw.
If improperly seated, the periphery of the LED/LCD display unit will not be flush with the EOI surface
and the unit will not function properly.
