Functions 

2.1 GENERAL FUNCTIONS 
2.1.1 FRONT PANEL CONTROLS 

Two high-reliability sealed front panel toggle switches for each channel are used to select 

operational and display settings.  One switch is designated “MENU (Back/Select)” and is 

used to accept the setting displayed and to move to the next menu item or go back to the 

previously displayed screen.  The second switch is designated “SCROLL (Up/Down)” and 

allows you to move through each selected menu. 

   

   

 

2.1.1.1 ORACLE 4H DISPLAY SELECT CONTROL 

The ORACLE 4H half width model provides four channel operation, but the LCD will display 

information for only two selected channels simultaneously. The top half of the display can 

be programmed to display information for either Channel 1 or Channel 3. The bottom half of 

the display can be programmed to display information for either Channel 2 or Channel 4. 

The selected physical channel number is always displayed in the upper right corner of the 

display in white text on a black field. 
To change the channel selected for display, press the MENU switch up to the 

Back / CH

 

position 

while in the main display mode 

(top level of the menu).  This will toggle the 

selected channel from 1 to 3 on the top display, and from 2 to 4 on the bottom display. For 

all other menu levels the up position of the MENU switch provides the 

Back

 function. 

The LEDs for the Detect (DET) and Fault (FLT) indicators are provided for all four channels 

and are always enabled regardless of the channel selected for the LCD display.  See 

section 2.2.3.
