SECTION 3: OPERATION
CONTROLS
EXTERNAL CONTROLS
AC Power
Apply AC power to the unit connecting the line cord supplied to the unit and then to an approved AC power source. Upon
Power-up a one-second beep sounds and the LCD backlight will be lit when power is on.
Fuse
The fuse is accessible from the rear panel of the unit, in the corner where the AC input is located. The fuse value is
T1.25A.
FRONT PANEL OPERATIONS
A Liquid Crystal Display (LCD) and Light Emitting Diode (LED) indicators have been organized such that important
information is available at a glance. The keypad has been arranged to allow an operator to easily change any parameter
from the front panel. See Figure 1-1 for the physical layout of the front panel.
INDICATOR BUTTONS
The “STATUS” indicator button LED will light red to indicate an active fault in the Frequency Converter. The indicator
button LED will light amber when there are no active faults but fault events have been stored in the log and the log has not
been cleared. Pressing the “STATUS” button will provide instant access to the Status screen information. Pressing the
“STATUS” button repeatedly will toggle the context of the display between the Fault Status screen and the Main screen.
The green “REMOTE” indicator button LED is lit when the unit is in remote control mode. When the “REMOTE” indicator
button is not lit, the unit is in local control mode. Operating parameters can be monitored from the front panel and from
the remote port at all times. When the unit is in remote control mode operating parameters can only be changed from
the remote ports. When the unit is under local control, operation parameters can be changed from the front panel only.
The unit will always power up in remote control mode. Also, after thirty minutes of inactivity at the front panel, the unit will
revert to remote control mode. The unit will always power up in remote control mode.
The “RF ON” indicator button LED will light green when the unit is carrying communications traffic. The “RF ON” indicator
button LED is not lit when the output is mute, interrupting communications traffic. While in local mode the operator can
press the “RF ON” indicator button to toggle the output between Mute and “RF ON” (provided that there are no active
faults). When a fault is active the output is forced to mute and the “RF ON” LED cannot be switched. After the fault
extinguishes and is no longer active the user-programmed state will be restored.
SCREEN NAVIGATION AND DATA ENTRY
The keypad includes four directional arrow keys for navigation and data entry. An “ENT” key is used for confirming data
entries. A beeper will sound to acknowledge each key press. An error tone will sound for illegal entries. While in Remote
mode, local data entry is prohibited. However, all system parameters can be examined.
The cursor will appear as either two vertical arrows, an up arrow “↑” on the top line and down arrow, “↓” on the bottom line,
or as a single right arrow “→”. This indicates the direction of navigation. While the cursor appears as two vertical arrows
use the up and down arrow keys to navigate between screens. Press the left or right arrow key and the cursor will appear
as a right arrow “→”. When the cursor is a right arrow “→” the data field to the right of the cursor is selected and the up
and down arrow keys are used to change the data in the selected field. Use the left and right arrow keys to navigate
between fields within a screen.
Pressing the “STATUS” indicator button will exit the data entry mode and resume the screen navigation mode with the
cursor returning to the two vertical (”↑” and “↓”) arrows at the left of the screen. Repeated presses of the “STATUS”
indicator button will toggle the display between the Fault Status screen and the Main screen.
