1. GENERAL INFORMATION The PAT Load Moment Indicator (LMI) DS 160 has been designed to provide the crane operator with the essen- tial information required to operate the machine within its design parameters. Using different sensing devices, the Load Moment Indicator monitors various crane functions and provides the operator with a continuous reading of the crane’s capacity.
4. GENERAL TROUBLESHOOTING INFORMATION This section explains how to handle a problem that may arise with the PAT DS 160 System. The procedures are given in flowchart format for the following sections. Start with the general flowchart below that will guide you to one of the noted detailed sections.

6. FUNCTION LOCKOUT PROBLEM: The lever lockout system of the crane is activated. Crane movements “hoist up” and (optional) “boom down” are stopped. Only if the crane is not in overload or two-block condition continue with flow chart. WARNING: If overload or A2B condition exists, use extreme caution and move the crane out of the condition.
7. NO DISPLAY PROBLEM: Blank console display with no warning light shown. All crane moments have been stopped. START Check fuses in central unit. Corrected Replace fuses. Measure voltage on the main board terminal strip between X1:1 (10-30V) and X1:3 (ground).
Page 16
PREVIOUS PAGE Measure voltage in the console between X1:1 (+12/24V) and X1:2 (ground). Refer to system wiring diagram. Check connections of the cable between Correct? console and central unit. Replace cable if necessary. Refer to system wiring diagram. Console/Display is defective. Replace the console. Refer to system wiring diagram.
8. ANTI-TWO BLOCK PROBLEM PROBLEM: Function of Anti-Two-Block System is faulty. START Check to see whether or not crane is in two-block condition. Correct? Lower hook down into safe position Check Bypass plug installed, if necessary Refer to system wiring diagram. Plug appropriate bypass plug into socket of Correct? junction box.

PREVIOUS PAGE Ensure the A2B switch is closed (weight or flag installed) and, if necessary, the byass plug is plugged into the boom nose box. Measure the A2B signal in the cable reel between X1:Brown and X2:Red wires on the slip ring with an ohmmeter. Switch closed =4700 ±500Ohms Switch open =>...
Page 19
PREVIOUS PAGE Connect the boom base connector. Connect wire #5 back to the terminal X1:9 on the connection board. Refer to system wiring diagram. Turn system power off. Check Anti-Two-Block signal in central unit with ohmmeter measure between X1:31 and X1:32. Anti-Two-Block switch closed = 4700 Ohms ±50 0Ohms Anti-Two-Block switch open =>...
9. LENGTH READING PROBLEM PROBLEM: Length displayed incorrect. Crane is not in “out of load chart” condition. START Check mechanical adjustment of length potentiometer in cable reel. With boom fully retracted, reset potentiometer by turning it slowly counter-clockwise until it reaches a soft stop. Refer to system wiring diagram and sensor adjustment procedure.
Page 21
PREVIOUS PAGE Measure supply to length transducer in cable reel between terminal 1 (ground) and 3 (+UB) Refer to system wiring diagram. Correct? Faulty wiring between central unit and length transducer. Check wiring Measure signal from length transducer in cable reel. The return signal is a current output and must be measured in series.
10. ANGLE READING PROBLEM PROBLEM: Angle displayed incorrect. Crane is not in “out of load chart” condition. START Check the cable reel for damages or movement of mounting bracket. Refer to system wiring diagram and sensor adjustment procedure. Repair or replace cable reel, if damaged or Correct? adjustments can not be made.
Page 23
PREVIOUS PAGE Measure signal from angle transducer in cable reel. The return signal is a current output and must be measured in series. Set Voltmeter to measure amps. Remove Wire #4 from X1:4 in the cable reel and connect one voltmeter lead to wire #4 and the other lead to X1:4.
11. LOAD READING PROBLEM PROBLEM: Load reading incorrect. START Check boom length reading on display. Reset length potentiometer. With fully retracted boom, turn potentiometer axle Correct? counter-clockwise until it stops . Refer to system wiring diagram and sensor adjustment procedure. Measure radius and check with the displayed radius.

PREVIOUS PAGE Measure signal from pressure transducers in central unit. The return signal is a current output and must be measured in series. Set Voltmeter to measure amps. Piston Side, remove Wire #2 from X1:32 in the central unit and connect one ammeter lead to wire #2 and the other lead to X1:32.
12. DATA TRANSFER CENTRAL UNIT <--> CONSOLE PROBLEM: Error Code “E93/E94" No data transfer to and from console, interference from crane electric, or console display frozen . START Check the H1 (TxD) LED on the main board ON/OFF. Refer to main board drawing. Make sure that the EPROM's are correct and plugged into the EPROM Module on the main board.

PREVIOUS PAGE Check if additional ground link between main board MP1 and central unit box mounting bracket is in place. Refer to Drawing 4. Install ground line - single cable minimum of AWG14 (2.0mm) Correct? between terminal MP1 and central unit box mounting bracket. Refer to Drawing 2 and 4.
Main Board Replacement Procedure 13.2 Refer to Drawing 4, central unit parts list for board location. 1. Turn system power off. 2. Remove the central unit lid. NOTE: Take care not to damage the boards with the screwdriver, when removing and inserting screws.
Calibration of Sensors Procedure 13.3 To access the calibration sensors screen use the following procedure. 1. From the operating screen, press and held both the ⇑- button and the “OK”-button for 5 sec- onds to display the maintenance screen. 2. The screen show the following selections: CALIBRATE SENSORS SENSOR OUTPUTS EXIT...
Length Sensor Calibration Procedure 13.3.2 After selecting ‘LEN’ in steps 1 through 4 at the beginning of this section complete the following pro- cedure. Fully retract the main boom. Displayed length indication FULLY RETRACT MAINBOOM XX.X ft Note: the displayed length indication is noted by XX.X in following steps.
Angle Sensor Calibration Procedure 13.3.3 After completing steps 1 through 4 at the beginning of this section, boom down to a flat angle and mechanically adjust the angle sensor. The angle should be set to be +/-0.0 of the measured angle. Material –...
Cable Reel Length Cable Replacement Procedure 13.5 Replace length cable using the following procedure: Refer to system electrical wiring diagram and cable reel - parts list Cut old cable at cable drum. Disconnect damaged length cable from junction box at the boom nose. Open cable reel cover and disconnect wiring from terminal block.
1) Spray Cleaning The enclosures used for the PAT DS 160 system are water protected to IP 65. This means protec- tion against the environment, such as rain. However, through the use of spray cleaner at short dis- tances, it is possible to force water through the gasket or strain relieves.
4) Defective Gasket The gasket underneath the lid seals the unit. The gasket needs to be in good condition in order to seal correctly. If the gasket is torn, brittle or severely bent, it needs to be replaced. Order a new gasket through your Link-Belt or PAT representative.
