COVER 2W5285 - Caterpillar

The MX100 controller is equipped with a built-in seven day exerciser. Pressing the "initiate" switch will start a timer that will continue for 167 hours and 40 minutes. An LED will illuminate in order to indicate that the timer has started. After 167 hours and 40 minutes, a load test or a no-load test occurs. The test is determined by the location of the jumper on the PC board of the controller.TSL - loadTSNL - no loadThe test lasts for 20 minutes. The LED for the "CDT" exerciser will flash when the test is in progress. This test does not include the delay to normal timer, or the engine cooldown timer. The test can be disabled by pressing the "disable/enable" switch. When the "disable/enable" switch is pressed, the NEXT test will not occur, but the timer will not be affected. After one week, the following test will start normally. The LED for the "CDT" exerciser will turn off when the "disable/enable" switch is pressed for the first time after initiating the timer. Pressing the "disable/enable" switch will re-enable the event. The LED for the "CDT" exerciser will turn on. The time of the event can be changed by initiating the event again. When the switch is pressed, the timer begins. The timer runs for 167 hours and 40 minutes. When you press the switch, the time is set. The next test will now start at 20 minutes before this time in one week (167 hours 40 minutes).Note: In order to avoid inadvertent initiating of the test, the button should be held down for three seconds when the button is pressed. In order to avoid inadvertent disabling of the test, the button should be held down for three seconds when the button is pressed. Note: A nine volt battery is supplied with the ATS in order to prevent the exercise timer from losing the "set exercise time" in the event of an outage of power. The battery can provide backup power to the processor for eight hours. If the battery has supplied power to the microprocessor for an extended amount of time, the battery should be replaced.Note: The nine volt battery cannot be plugged into a PC board that is de-energized. The PC board includes large capacitors that cannot be charged by the battery. If the capacitors are charged, the battery will discharge eventually due to the load of the PC board. Therefore, do not install a battery until the PC board is energized. The battery will be able to maintain the "CDT "set exercise time"" in the event of an outage.
