Voltage is measured at the later terminal. For example, the red test pin + is connected to terminal "A" and the black test pin - is connected to terminal "B".

3. Meaning of Symbols

a. The following list describes the meaning of specific symbols:  "C-ground" : Ground terminal for the chassis

 "P-ground" : Ground terminal for the platform  "R-ground" : Ground terminal for the relay panel  "Cab-ground" : Ground terminal for the cab 4. Preliminary Check

a. Connector

Check the connection of the connector before a troubleshooting procedure is performed. Inspect the connector for moisture. Moisture in a connector can cause a poor connection. Ensure that the connectors are mating correctly. Ensure that the pins in the connector are secure.

b. Continuity

Ensure that continuity is present between the following items:  "C-ground" - "P-ground"

 "C-ground" - "R-ground"  "P-ground" - "Cab-ground"

(32)

Turn the disconnect switch to the OFF position before you perform the continuity checks. The power is OFF in order to prevent damage to the tester and the circuit.

5. Preparation

a. Turn the key start switch to the OFF position.

b. The hydraulic control lever is in the LOCKED position.

c. Ensure that the controller, the harnesses and the connectors are connected.

Note: Ensure that disconnected wires do not contact the machine in order to avoid damage to electrical components when power is applied.

Replacement For Machines Only With Accelerator Cable

1. Install the actuator.

2. Insert the joint of the accelerator cable through the hole in the lever. Install the nut in order to hold the cable in position.

3. Turn the nut and the locknut of the accelerator cable in the counterclockwise direction until the nuts are separated.

4. Turn the lever by hand in the counterclockwise direction to the position of high idle. 5. Insert the other threaded portion of the accelerator cable into the notch of the support.

6. Secure the screw cap and the boot so that the screw cap and the boot will not turn. Then turn the nut until the governor lever touches the high idle stop.

(38)

8. Tighten the locknut (27 ± 3 N·m (20 ± 2 lb ft)) against the support. Ensure that the nut remains in position while the locknut is tightened against the support.

9. (If applicable) Reinstall the two clamps to the accelerator cable. Do not allow the cable to twist. Note: Ensure that the governor lever is in contact with the high idle stop. Also, ensure that the nut is correctly tightened in order to ensure that the accelerator cable has the correct tension. The setting of the engine speed or an overload condition of the governor actuator could result if the cable is not tightened correctly.

Note: The minimum allowable bending radius for the cable assembly is 150 mm (6 inch).

Replacement For Machines With Accelerator Cable and Decelerator Cable

1. Repeat step 1 through step 9 in "For Machines Only With Accelerator Cable".

2. Insert the joint of the decelerator cable through the hole in the lever. Install the nut in order to hold the cable in position.

3. Loosen the nut and the locknut on decelerator cable.

4. Insert the other threaded portion of the accelerator cable into the notch of the support.

5. Tighten the nut until the sag in the bellows is no longer present. Loosen the nut by five turns. Note: The minimum allowable bending radius for the cable assembly is 150 mm (6 inch).

Adjustment

1. Loosen the nut and the locknut of the accelerator cable. The nuts should be separated as far as possible. 2. Install the accelerator cable and the decelerator cable to the lever.

3. Insert the threaded section of the accelerator cable into the support.

4. Turn the lever clockwise toward the engine until the lever hits the stop for the high idle.

5. Tighten the nut until the sag in the bellows is no longer present. The nut should be tightened two additional turns.

6. Secure the accelerator cable to the support by tightening the locknut.

7. Insert the threaded section of the decelerator cable into the notch of the support.

8. Tighten the nut until the sag in the bellows is no longer present. Loosen the nut by two turns.

9. Secure the decelerator cable to the support with the locknut. Then, tighten the locknut against the nut. Ensure that the nut does not turn as the locknut is tightened.

(39)

Note: For more information, see the topic Testing And Adjusting, "Governor Actuator - Calibrate". 1. Start the engine. Perform the calibration procedure for the governor actuator.

2. After the calibration procedure has been performed correctly, the error log is cleared. Note: For more information, see Testing And Adjusting, "Logged Error Mode".

Governor Actuator -

Calibrate

SMCS - 1716-524

Note: The 325C, M325C MH, and 330C series does not have a governor actuator.

This function can memorize the rotation angle of the governor actuator and the no-load engine speed. This information is saved into the controller after the accelerator cable of the governor actuator has been replaced, installed and/or adjusted. The controller will use the information that was saved in order to determine the target position for the actuation of the governor actuator.

Note: Ensure that the calibration procedure for the governor actuator is performed when the governor actuator, the accelerator cable or the controller has been replaced or installed. The temperature of the hydraulic oil should be 50 °C (122 °F) prior to the calibration.

Warnings

If the fourth line of the display shows any of the following warnings a failure is present. See the following table 2 for a detailed description of the warning displays.

Table 2 Warning Codes

Display Warning Corrective Action

Wire Pitch X (X is a number from 0 to 9)

Wire nut is installed too loose by X pitch. X can be a

positive or negative number. Turn clockwise.

Tighten the accelerator cable by the displayed pitch. Perform the calibration again.

Wire Pitch X (X is number from -9 to 0)

Wire nut is installed too tight by X pitch. X can be a positive or negative number. Turn clockwise.

Loosen the accelerator cable by the displayed pitch. Perform the calibration again.

WARNING 01 Insufficient high idle

High idle is less than the specified value due to malfunction of the engine, incorrect installation of the governor cable, poor fuel, etc. After the engine has been inspected for a malfunction, reinstall the cable and perform the calibration again.

WARNING 02 Incorrect installation of

cable Reinstall the cable and perform the calibration again.

WARNING 03 Excessive low idle

Low idle is more than the value specified due to a malfunction in the engine, an incorrectly installed governor cable, etc. After the engine has been inspected, reinstall the cable and perform the calibration again. WARNING 04 Excessive hysteresis Ensure that the cable is adjusted correctly. Reinstall the

(44)

cable and perform the calibration again.

WARNING 05 Unstable high idle

High idle is unstable due to a malfunction in the engine, an incorrect installation of the governor cable, etc. After the engine has been inspected, reinstall the cable and perform the calibration again.

WARNING 06 Unstable dial speed

The speed for the dial setting is unstable due to a

malfunction in the engine, an incorrectly installed cable, etc. After the engine has been inspected, reinstall the cable and perform the calibration again.

Errors

If the fourth line of the display shows any of the following errors a failure is present. See the following table for a detailed description of the error displays.
