6. Operating Procedures 

 

6.1. Front Panel Controls 

6.1.1. Displays 

In addition to providing current and voltage meters the displays can display other supply 
information.  The displays can show numeric parameter values or text messages. 

6.1.1.1.

 

Run Screens 

Run screens are shown during normal supply operation.  An example of a run screen is the 
meters run screen which displays the output current and output voltage and allows for display and 
edit of the current and voltage settings.  Other examples of run screens include totalizer time, 
cycle time, and diagnostics.  The ‘SET’ lamp is off when a run screen is displayed. 

6.1.1.2.

 

Menus 

Menus can be displayed to configure the power supply.  The unit configuration menu contains 
items that are generally only set when a power supply is initially installed.  The setup menu 
contains general cycle configuration such as selecting RTC or ATC control and setting current or 
voltage tolerances.  The display select menu provides a method to select which run screen is 
displayed.  The ‘SET lamp is on steady when a menu is displayed.  The ‘SET’ lamp blinks on and 
off when a parameter is displayed.   

 

6.1.2. Encoder Functionality 

The encoders can be turned clockwise or counter-clockwise.  Each encoder also functions as a 
momentary switch when it is pushed in.
