ADAPTER-CROSS 2501427 - Caterpillar

Manual Mode
When the switch is in the manual position the system will operate in the manual mode. This mode is enabled after the loss of the cranking signal. The use of this mode is to help the engine run smoothly when cold, and to reduce or eliminate white smoke.1. Power is supplied when jacket water temperature is less than 13°C (55°F) and crank terminate has been reached.2. The solenoid is supplied with full battery voltage to open the valve.3. The control group cuts the voltage by energizing the resistor assembly to protect the solenoid.4. Ether is injected until jacket water temperature is 21°C (70°F) or the operator releases the switch.
To protect the engine from damage due to cold starts below 13°C (55°F), the toggle switch must be pressed and held in the manual position until the engine can operate smoothly without ether. Failure to do this will result in piston and ring damage.
Locomotive Engines
The locomotive engines use a slightly different arrangement. Locomotives operate on a 64 volt system. This requires a different valve assembly that does not need the controller/resistor combination.Operation
Auto Mode
When the switch is in the auto position it will operate in the auto mode. The auto mode receives power only during cranking. Ether is injected until the cranking signal is lost, or the jacket water temperature requirement is met.1. Power is supplied when the jacket water temperature is less than 13°C (55°F) and the engine is cranking.2. The solenoid is supplied with full battery voltage to open the valve.3. Ether is injected until the cranking signal is terminated, or the jacket water temperature is 21°C (70°F).Manual Mode
The difference between the manual mode operation above, and the locomotive manual mode, is how the power is supplied. The power comes from the non-essential locomotive power. The output power from the battery charger is available only when the engine is turning.Starting Procedure
Operator In Sight Of The Exhaust
1. Initiate start sequence with the system in the auto mode. This will inject a metered amount of ether for the duration of the cranking cycle.2. Switch to manual mode after engine starts, and inject ether to clear up visual white smoke.Remote Operation (Cannot See Exhaust)
Install a timer on the manual side of the switch to inject ether. It will be necessary to bypass the switch due to the momentary nature of the manual side.1. Remove the wire to the manual side of the switch and use it as input to the timer. Install the output from the timer to the manual side of the switch. Timer is customer supplied. Timer is normally closed for time indicated on chart.2. Set the timer by performing tests to see how much ether is needed to clear the white smoke. Since this will be a function of ambient temperature, inlet and exhaust restriction, tests at different conditions would be ideal. If testing cannot be performed, use the following chart as an approximation. Plumbing Components
