Check the units and the maximum (full scale) of the transducer
(NOTE: TC50A will automatically check and set the ZERO and
MAX values of the transducer connected.)
Enter the TgTq (Target Torque) of the application. (Dynamic
torque setting)
After setting the above values, there are five steps to setting up
an application.
LEARN TGTQ - RUN TOOL
Run the tool on the application, holding the trigger until the
system stops the tool.
NOTE: THIS STEP MAY TAKE UP TO (15) SECONDS. WAIT
UNTIL THE CONTROLLER SHUTS OFF THE TOOL AND THE
DISPLAY SHOWS "CYCLE COMPLETE."
The LEARN TGTQ process will dynamically adjust the airflow to
the tool and monitor the transducer torque signal during the
sample run. The controller will stop the tool when the torque
signal reaches the target value programmed into the selected
parameter set. This process is a Closed-Loop control cycle.
LEARN REHIT - RUN TOOL
Cycle the tool on the previously tightened bolt.
LEARN FREERUN - RUN TOOL
Operate the tool in free air until the controller stops it.
LEARN PREVAIL - RUN TOOL
Run the tool on the application to allow the controller to "Learn"
the joint characteristics during fastener rundown.
LEARN CURVE - RUN TOOL
In this final step (with the transducer still on the tool), run the
tool on the actual application. The controller will learn the
signature of the application using closed loop control based
upon the transducer measurement.
After the tool shuts off, the Pset is programmed.
NOTE: The TC50A control system will monitor the transducer
during this step and will run the tool until the TgTq is achieved
through closed-loop control. IF THE JOINT IS VERY SOFT,
THIS MAY TAKE UP TO (5) OR MORE SECONDS. When this
cycle time is too long, the selection of a higher torque capacity
tool is recommended.
The - TEST SETTINGS - screen will appear and is used to test
the set-up while allowing the operator to use the back-up key to
go back and adjust any settings if the results obtained in the
TEST SETTINGS mode are not correct. Use this screen to
check for proper error detection.
ONCE YOU PRESS THE ENTER KEY, NO FURTHER AD-
JUSTMENTS ARE ALLOWED. IF CHANGES ARE REQUIRED,
YOU MUST GO BACK TO THE PARAMETER SETUP SCREEN
IN THE MAIN MENU AND START OVER.
The Pset is now programmed and ready for
production use.
UNDER THE ePro logo:
By lightly pressed on the ePro logo, the following options will be
displayed:
• CHANGE DISPLAY
• This allows selection of displaying either the TQ from a
transducer (if one is plugged in) or to display the TgTg
(target torque) as programmed.
• CAL CORRECT
• Provides an easy calibration adjustment to an inde-
pendent system or torque wrench.
• REHIT STATUS
• The controller defaults to include the use of REHIT as
an error. By turning this feature off, the controller will
ignore any rehit condition.
• CYCLE DELAY
• This setting will determine the "off" time between the
end of one run-down and the resetting of the tool for
the next cycle. A default value of 02500 will keep the
tool off for about one (1) second prior to allowing the
operator to press the trigger for the next fastener. If
this is too slow, adjust (by using the UP/DWN buttons)
the value down to approximately 1000-1200. Any lower
may be too quick and may not allow the operator
enough time to release the trigger. A higher value will
cause the tool to reset slower.
• LOCK OUT
• Activating this option will lock out the program keys
from the operator allowing only Pset selection and
Reverse Override.
PARAMETER SETUP - MAN(ual)
The MANUAL mode is used whenever:
• No transducer is available
• RESIDUAL (static) torque setting is desired
• The application has wide joint rate variations
• The application has high prevailing torque
• When setting up a direct drive tool using the standard pulse
tool software.
NOTE: It is best to install the correct software program to suit
the type of tool being used.
Follow the steps below to program a Pset using the MANUAL
method:
1.
Select the Pset desired
2.
Set Count (number of fastenings per Batch/Cycle)
3.
CAL TRANSDUCER
NOTE: If a transducer is used, the display will show the
monitored reading on the MANUAL TEACH screen next to TQ.
If no transducer is connected, press the "NO" option to advance
to the — MANUAL TEACH — screen.
In the MANUAL TEACH mode, the SIG value is defaulted to 075
and may be adjusted EITHER UP OR DOWN. This will adjust
the airflow/pressure ratio to allow you to adjust torque level.
However, a setting of 110-115 will most likely be the maximum
unless your air supply is in excess of 90 psi and 50 scfm.
There are five steps to setting up an application in MANUAL
mode.
— MANUAL SET-UP —
Run the tool on a sample fastener, holding the trigger until the
socket stops turning.
NOTE: THIS STEP MAY TAKE UP TO (5) SECONDS. In
MANUAL mode, the control of the tool shut off is left to the
operator. After manually stopping the tool, measure the
torque applied using the standard method as approved by
your company. If the torque measured is not correct, adjust
the SIG value using the UP/DWN keys and retry until the
torque desired is achieved.
Once the torque level is correct, press the enter key. Input the
value measured to the SET PARAMETER TgTq screen.
LEARN FREERUN - RUN TOOL
Operate the tool in free air until the controller stops it.
LEARN PREVAIL - RUN TOOL
Run the tool on the application to allow the controller to "Learn"
the system characteristics during fastener rundown.
LEARN REHIT - RUN TOOL
Rerun the tool on the fastener that was just run down under the
LEARN TGTQ step. Hold the trigger until the system shuts off
the tool.
