13872A 1 Force LUBRICANT-SPECIAL (8 OZ.)

Personal injury can result from improper engine operation.Deviation from these installation instructions can result in improper engine operation which could cause personal injury.Follow the installation instructions before engine operation.
Ignition Module Timing Switch, LED Indicators, And Computer Serial Port
A rotary switch with 16 positions is installed inside the CIS Ignition. This switch is used in the "Mag-Cal" mode of the Caterpillar TCM in order to adjust the retarding effect from the Cam Position (Hall Effect's) signal. This is done in order to stimulate the timing that was formerly provided by the Altronic III at low engine rpm. Adjustment of this switch simulates rotating the Altronic III mechanical position. The timing range is from 0 degrees to 15 degrees with a 1 degree resolution.
Five LED indicators are provided inside the Ignition Module for troubleshooting purposes.
The red "Power LED" is continuously illuminated when the unit is powered and the microprocessor is running.
The red "Power LED" flashes when the "Power LED" is not operating correctly and the unit has power.
The red "Power LED" is off when the unit has no power.
The red "TX LED" flashes when the unit is transmitting on the RS-485 serial link.
The red "RX LED" flashes when the unit has received a transmission on the RS-485 serial link.
The red "ALARM LED" illuminates in order to indicate a warning or a fault is present.
The green "H.E. PICKUP LED" illuminates when a magnet turns on the Hall Effect sensor.
One RS-485 serial communications port is provided within the Ignition Module. This port is normally used for communication to the optional Display Module .The Display Module
The Display Module serves as the customer interface module for the CIS system. A RS-485 serial communications port is used in order to connect the Display Module to the Ignition Module .
An alphanumeric LCD display is used in order to provide an output to the user. A keypad with a sealed membrane is used in order to input the user's data. The LCD display and the keypad function together in order to provide an interactive customer interface module. The interface prompts the user as different functions are selected.
All actions and adjustments are immediate. The actions and adjustments are performed on an incremental basis by using the up arrow and the down arrow. All of the entries from the keypad are performed in the Electronically Erasable Programmable Read Only Memory (EEPROM). This EEPROM retains previous settings even after an engine shutdown or an ignition power shutdown.
Large letters are used on the display screen in order to designate an active selection. Small letters are used in order to indicate other possible options.Understanding The Home Screen
A series of home screens are used in order to describe the current status of the ignition system. The LCD always reverts to one of the home screens after an operation is completed. The LCD will also revert to one of the home screens if an operation takes too much time. The home screen is designed in order to display the most critical operating parameters on one screen.
All of the home screens show the status of the ignition in the upper left hand corner. The engine speed is displayed in the upper right corner. The status of the TCM is displayed on the lower portion of the screen.

The "READY" message is displayed in the upper left hand corner when the ignition is ready to begin cranking the engine. The TCM would normally be in the Manual Mode.
Illustration 2 g00329096
Once the engine begins turning, the "SYNCING" message is displayed while the engine verifies signals from the engine pickups. The proper signals can be identified in as few as two engine revolutions.
Illustration 3 g00329097
The "FIRING" message is displayed when the ignition begins firing. Additional data is provided on this screen in order to describe the selected mode of operation for the ignition. The level of energy (E1, E2, E3 ) is in the middle of the upper screen in small characters. The type of striking is positioned next to the level of energy. The TCM is displayed in the AUTO Mode.
