Tattletale Mode is a tool for management and maintenance. The history of the machine can be recorded by this mode. The main display module records the extreme value for each condition of the machine that is monitored. The values come from sensor inputs, switch inputs and the Cat Data Link. The values in tattletale mode are updated whenever a value occurs with more importance than the previous value. These values are ignored for a short period of time after each start-up. This allows the machine systems to stabilize before the recording of information. Gauges (5) show the highest reading or lowest reading that has been attained by the corresponding machine system. The gauges show the highest reading for systems with increasing abnormal values. The gauges also show the lowest reading for systems with decreasing abnormal values. The gauge alternates between the highest reading and lowest reading. This will occur for the gauges that are double ended. Tachometer (6) and speed readout (7) show the highest reading that has been obtained. Alert indicators (4) turn on when an abnormal condition has existed. Information from the tattletale is retained until the information is cleared. Grounding the clear input erases the information. After clearing, all information is reset to a nominal value and the recording of new extreme values begins. Note: The date, time or duration of the extreme value that has occurred is not recorded.Example This example explains the information that is shown in the illustration for the Tattletale Mode.
Gauge (5) for the engine coolant temperature has a pointer that indicates a value above the normal temperature range. Therefore, a high abnormal value has existed in this system.
Gauge (5) for the brake air pressure has a pointer that indicates a value below the normal pressure range. Therefore, a low abnormal value has existed in this system.
Gauge (5) for the brake oil temperature has a pointer that indicates a value in the normal range. Therefore, no abnormal value has existed in these systems.
Gauge (5) for the fuel level has a pointer that indicates a level of 50%. Therefore, the lowest amount of fuel that has existed is 50%.
The pointer on tachometer (6) indicates a maximum value (2100 RPM). Therefore, an engine speed of 2100 rpm has existed.
Speed readout (7) shows "13 MPH". Therefore, 13 MPH is the highest ground speed that has been attained.
Alert indicator (4) is ON. Therefore, an abnormal condition has existed in this system.
All other alert indicators (4) are OFF. Therefore, no abnormal values have existed in these systems.Note: No information from the tattletale mode is stored for the highest transmission gear or lowest transmission gear that has been selected.
