Error Message

1. Display of Error Message

◆The language (English or Japanese) of error message is selected at the [ Language] menu in the adjustment mode.

2. How to Read the Error Message

1. Error code in the error message is represented by four-digit codes.

Error code: E1 E2 E3 E4 lndividual code

Group code

0:Alarm

1:Abnormal communication

2:Abnormal detector

3:Abnormality inside AML

2. The highest rank (E1 in the above figure) indicates error groups. The each next three digit figure (E2 through E4 above) indicates individual error code under error groups.

1. If AML system detects the trouble in ordinary use (user mode), it makes beep sound as well as displays error message on the moment display. Display example: [Error:2001]

Shows that an error of error code 2001 has occurred.

2. This error message display continues till the cause is eliminated.

3. While the adjustment or maintenance mode is being used, only beep sound informs the operator of the occurrence of trouble. The display on the moment display, however, does not change to the error message display automatically. Current message keeps displayed.

4. To confirm the error message in the adjustment or maintenance mode, press the lift height limit key. While you are pressing the key, the error message is shown on the moment display. (It may take some seconds for the display to change.)

5. If trouble remains even when you return to the user mode after exiting adjustment or maintenance mode, corresponding error message appears on the moment display.

3. Since group code “0” indicates a warning condition, it does not always mean that there is a problem in the system when an error message is displayed.

4. For this reason, warning-related error messages are not registered in the system’s error history memory. Warning-related error messages are shown in the moment display in the same way as message for other group codes.

3. How to Read the Error History

1. Error history records 50 errors, maximum, of the group code, in order of occurrence. Those beyond 50 will be made to disappear in the order of occurrence.

2. See the “Error Data Display” in the “Functions of and How to Use Maintenance Mode” section for reading the error history.

Message Description

Warning : 0093 Enabling angle for jib set

＊This error code is displayed with jibs of a type having rollers that engage with guides on the boom during extension and stowing without using any assist. rope (like the jib on TR-200EXC).

Situation: Crane operation is automatically stopped when the elevation angle has reached the specified angle suitable for jib extention/stowing.

Cause: The setting of AML is made “jib set “, the boom is raised and its elevation angle has reached the specified angle sutable for jib extension/stowing.

Angles suitable for jib extension/stowing are defined as follows:

Extension

A boom angle at which the jib will not either shake widely or interfere with the swing table in the motion that the rollers on the jib come off the guides on the boom when the boom is extended.

Stowing

A boom angle at which the rollers on the jib to engage with the guides on the boom so that the jib can be stowed, when the boom is retracted.

Action: During jib extension

During jib stowing

During other operation

: : :

Extend the boom to extend the jib. Retract the boom to stow the jib. Stop the boom if it is being raised. Change the setting of AML to any other mode from “Jib set”.

Input status from the detector can be confirmed by “Ai” check of “Maintenance” menu and “Elevating cylinder pressure monitor”.

(“Ai” check related items: [Boom L], [Boom A], [MMT V], [DRC EXT], [DRC RTR] etc.)

Raise the boom. (error code: In case of 0113)

Message Description

Warning : 0115 Approximation to the elevation stop angle

Situation: The crane will stop if boom elevation is continued. (Precautional warning)

Cause: The boom angle becomes close to the position where the crane automatically stops due to the elevating cylinder stroke end or boom angle limit restriction functions (boom upper/lower limit, lifting height limit).

Action: Stop boom operation.

Move the boom to the non-critical side.

Cause: AML’s CPU board and/or analog board are defected.

Action: Replace the AML’s CPU board and/or analog board.

Disassembly of AML Main Unit

1. Removing Front Panel/Display Board

[NOTE]

◆Do not touch each front and rear face of the boards by hand when removing the boards.

1. Take off the front panel and display board as an assembly from the unit case by unscrewing screw(a).

2. Removing Rear Panel/Connector Board/Current Output Board

[NOTE]

◆Do not touch each front and rear face of the boards by hand when removing the boards.

1. Take off the rear panel, connector board and current output board as an assembly from the unit case by unscrewing screw(c).

3. Removing CPU Board/Analog Board/Power Board

[NOTE]

◆Do not touch each front and rear face of the boards by hand when removing the boards.

1. Take off the front panel and display board as an assembly from the unit case by unscrewing screw(a). Then take off the rear panel, connector board and current output board as an assembly from the unit case by unscrewing screw(c).

3.1 Notes on ROM/EEPROM Replacement

[NOTE]

◆EEPROM stores the adjustment values for each specification number. When replacing the CPU board, reuse the EEPROM after removing it from the broken CPU board.

When replacing ROM and EEPROM, make sure that the concavities of IC and socket meet each other.

2. Take off the CPU board by unscrewing screw(f). Then remove the spacer(h) and take off the analog board and power board as an assembly from the unit case. Next, separate the analog board by removing nut(g).

Multiplex Data Transmitter (MDT) Input/Output Nos. and Corresponding Signals

1. Boom Length Detector

1. Retract the boom fully, set the boom angle to 0 degree and turn off the PTO switch

2. Pull out the connector of the detector and measure resistance of the potentiometer. The specified resistance values are as follows:

C-D:833 ±167Ω

B-D:458±92Ω

3. Swing Angle Detector

1. Swing the boom to over-left and turn OFF the PTO switch.

2. Pull out the connector of the detector and measure resistance of the potentiometer. The specified resistance values are as follows:

R-B:500±75Ω

W-B:0 15Ω

4. Outrigger Extension Width Detector

1. Stow the outriggers and turn the starter switch to OFF.

2. Boom Angle Detector

1. Retract the boom fully, set the boom angle to 0 degree and turn off the PTO switch.

2. Pull out the connector of the detector and measure resistance of the potentiometer. The specified resistance values are as follows:

C-D:833 ±167Ω A-D:146±29Ω

2. Remove the wire for the detector from the outrigger and hold the wire, letting it protruding by 3.1 in (80mm) from the guide hold of the detector.

3. Pull out the connector of the detector and measure resistance of the potentiometer. The specified resistance values are as follows:

R-B:2000± 100 Ω W-B:200±30 Ω

Checkin g the Detectors

5. Pressure Sensor for Moment Detection

1. Turn ON the PTO switch. (5-V DC will be applied between R and B of the pressure sensor connector.)

2. Measure the output voltage between W and B of the pressure sensor connector.
