WX9 ASD Installation and Operation Manual 31
Electronic Operator Interface
The WX9 ASD Electronic Operator Interface (EOI) is comprised of an LED screen, an LCD screen, a
rotary encoder, and five keys. These items are shown on pg. 32 .
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 WX9 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).
The EOI may be mounted remotely using the optional ASD-MTG-KITQ9 . The kit contains all of the
hardware required to mount the EOI of the 9-Series ASD remotely. See the section titled EOI Remote
Mounting on pg. 35 for more information on this feature.
System operation and EOI operation while using the remotely-mounted EOI are the same as with the
ASD-mounted configuration.
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 Lockout 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 21 on pg. 32 ). 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.
