INT_CT121 (Intermittent Tester)

Posted on by

Intermittent Tester (INT_CT121)

Intermittent faults are difficult to locate in any cable. These are found mostly in crimped flat cables and can be located only after failure in the field. INT_CT121_32 tester tests a cable for correct continuity and then for intermittent faults. Any asynchronous occurrence of intermittent fault is captured and indicated. Testing can be continued or can be aborted.

Futura has launched a One-to-one tester with intermittent checking.
•It is an enhanced version of CT121.
•Models are INT_CT_121_32 and INT_CT_121_64 for upto 32 circuits and upto 64 circuits.(32 way cable and 64 way cable).
•This tester will not check cables with mid-joints.
•Relay output on Passing a cable
•Futura can provide test boards for FRC cables.

What is intermittent fault?

• ‘Intermittent’ is occurrence of momentary disconnection in a cable.
• Generally it is observed in IDC cables like FRC.
• For example, FRC cable; normally shows continuity. But, because of movement, disconnection occurs for a very short period of time (microseconds or milliseconds)
• In other words, cable is generally ‘short’ , but ‘opens’ sometimes for a short time.
• It is a pain area, as it is most likely that the product works OK before dispatch and develops fault after installation because of ‘intermittent’

Why regular testers cannot locate intermittent faults?

Regular continuity testers, scan inputs i.e. points or circuits, at a regular time interval.
• For example a 64 points tester will check points 1 to 64, after every 1 millisecond.
• Hence each ‘point’ will be scanned after 64 milliseconds.
• Tester will find open only if ‘disconnection’ is at the moment of scanning.
• ‘Intermittent’ is an asynchronous event. Meaning it can occur anytime.
• Hence, if disconnection in a cable, occurs, when tester is checking other points, tester cannot locate disconnection.

Technique used by Futura:

Futura has developed an intermittent finding technic for the first time in India.
• An additional ‘hardware circuit’ in each point or circuit, ‘memorises’ the asynchronous occurrence of disconnection.
• Hence when tester scans a point, it is checking if disconnection occurred earlier.
• Intermittent to occur; cable has to be ‘moved’ or ‘pulled’ or ‘rotated’.

Our test process:

• Test system consists of a tester and a test board or rig to mount the Cable / Harness Under Test.
• Testing is done in two steps. First is to check correct ‘continuity’. If OK then to check ‘intermittent’.
• Tester keeps checking for intermittent continuously and displays result as Pass.
• Cable under test is moved to generate intermittent fault.
• If a momentary disconnection occurs, tester displays intermittent fault with the circuit number.
• Intermittent test can be started again by pressing a key and test process repeated.
• Testing can be stopped by pressing a key.
• Even after moving Cable under test, intermittent does not occur, test can be stopped by pressing a key.

Features:
  • Intermittent checking option along with continuity
  • Fast testing.
  • Locating precise intermittent faults.
  • Compact.
  • Available in two models for 32 way and 64 way cables.
Advantages:
  • State of the art, reliable technology.
  • Easy and quick installation.
  • Relay output on passing a harness to drive marker or pneumatics.
  • Printed and video manual helps easy installation.
Benefits:
  • High speed operation, fast and reliable testing.
  • Durable and reliable tester.
  • Adaptable to any board for Futura testers.

  • Futura MSPHTM

Function :

  • Tester will check continuity by passing a low current in a few milliamperes and at low voltage i.e. 5V DC.
    Maximum number of stages i.e switch positions can be 32 nos. Maximum number of points i.e. terminals of switch connections can be 64.
  • It is an extension of ‘Cable Harness Tester’ in terms of number of stages.
  • Program for each stage is written in any text editor like notepad.
  • It will mention a netlist meaning list of points connected in this stage and for maximum 32 such stages.
  • User interface is through 16*1 alphanumeric LCD and 6 keys keyboard.
  • Apart from standard harness tester facilities, following will be additional.
    • Number of stages increased to 32 nos.
    • Display of multiple faults. Stage-n has passed.
    • And display shows an error because operator has not switched to the next position.
    • In OK condition, whenever operator switches to the next position, stage-n+1 will be passed and result displayed.
    • When Not OK, fault are displayed even if switch is at correct position.
    • After confirmation of fault or error by operator, to save this fault, ‘down’ key is pressed.
    • Tester proceeds to next test. Maximum 10 such faults will be saved i.e. recorded in the memory.
    • At the end of the test, fail will be indicated. These recorded faults can be uploaded to PC through RS232.
    • Faults are then erased from memory. If a PC is connected to RS232 port and appropriate software is running, PC receives the fault.
    • Faults can be printed by connecting any parallel port printer.

Auto manual mode.

  • In auto and manual mode, recording of fault is available as above.
  • In auto mode tester will automatically test each stage and then each unit.
  • In manual mode, after each stage test, operator will have to press ‘up’ key to start testing of next stage.

Operation:

Regular Testing.

• Switch on tester.
• Select appropriate program using keyboard.
• Cross check setings such as auto/manual, connection of PC, printer etc., number of stages and number of points.
• Start testing.
• For correct continuity of a stage, small buzzer will sound.
For a correct complete unit under test, long buzzer will sound.
• For incorrect or faulty unit, press a key to save fault and to move on to next stage, until 10 faults are displayed or testing of unit is complete.

Programming a new unit:

• Select appropriate program using keyboard.
• Select data transfer mode using keyboard.
• Prepare a text file of program.
• Use software provided to download program to tester.
• Cross check number of stages and number of points received in each stage.
• Set up tester to test unit.
• Start testing.
