"Override" Test Function

Upon selecting an "OVERRIDE" test function, current operation will be represented as a percentage of its full range, this value will be displayed on ECC control panel. Display will alternate between "--" and what it normally should be. Alternating display is a reminder that function is not currently being overridden. Pressing "WARMER" or "COOLER" buttons begins override at which time display will no longer alternate. Pressing "WARMER" button increases value while pressing "COOLER" button decreases value. In this way it is possible to see what effect changing this value will have, and thereby suspect systems can be checked. Normal system control can be achieved in the following 3 ways:

• Selection of another override test will cancel current override.
• Selection of another system will cancel current override.
• Overriding value beyond either extreme (zero or 99) will display "--" momentarily, and then jump to opposite extreme. If button is released while "--" is displayed, normal program control will resume.

After selecting an override test, pressing "OFF" button will allow selection of another test type, data "INPUTS", or data "OUTPUTS". The following are a summary of each override display:

• BS00 - TEST DISPLAY
  
  This test will display "NONE" as no overrides are active at this point.
• BS06 - GENERATOR DISABLE
  
  Generator disable override will control to zero (generator ON) or 99 (generator disabled), as long as button is held. Normal control will resume upon release of buttons.
