Table 1
Alarms and Default Conditions for Arming of the Alarms    
Alarm     Condition    
"CYL DEV"     The circuit for the input for engine rotation is open.
The temperature for arming of the parameters is achieved.
The start-up timer has expired.    
"CYL HI 1"    
"CYL HI 2"    
"TO HI 1"     The circuit for the input for engine rotation is open.    
"TO HI 2"    
"TI HI"    Note: Any alarm can be configured to be armed by the input for engine rotation only. Any alarm can also be configured to be armed by all of the conditions. However, custom wiring, a computer, and the proper software are required. For more information, consult the appropriate Caterpillar Engine Customer Service.Input for Engine Rotation - It is important for the circuit of this input to be open during normal engine operation. When the circuit is open, the scanner can activate alarms.When the circuit is grounded, all the alarms are deactivated and the engine is not protected against problems with exhaust temperatures.It is not necessary to connect the circuit for input of engine rotation. The circuit is left open by the factory.Note: The arming temperature and the start-up timer are adjusted with the "SETPTS" menu. Refer to Systems Operation, "System Configuration Parameters".Arming Temperature - To arm the alarms, the average cylinder temperature must rise above the arming temperature. This temperature can be reprogrammed with the keypad.The average cylinder temperature must stay above the arming temperature during normal operation. If the average cylinder temperature becomes less than the arming temperature, the alarms that depend on the arming temperature are deactivated.Start-up Timer - The start-up timer starts when the arming temperature is achieved. When the start-up timer is running, the display shows the time in minutes and in seconds until the timer expires. The display shows "TIMER", "xxm", and "xxs".If no alarms are configured to use the timer, the screen for the start-up timer is not displayed during start-up of the scanner.For arming of the selected alarms, the average cylinder temperature must stay above the arming temperature until the timer expires. Otherwise, the timer restarts.
"ENTER/ACK" key To cancel the start-up timer, press the "ENTER/ACK" key.
"RESET" key To reset the timer to the full amount of programmed time, press the "RESET" key.
