- Page 6 CALIBRATION AND ZERO A calibration process must be performed before your amplifier is ready to indicate tension. Select an appropriate calibration weight. The weight determines the value of web tension that will produce full output of the TA1. For example: A 15 lb weight will result in full output at 150 lbs of tension if the 10% calibration is performed.
- Page 7 CALIBRATION AND ZERO continued... 1. ZERO: Ensure nothing is hanging on or pressing on the transducer roll (including the calibration rope). Press the ZERO pushbutton on the unit front panel for at least 1 second. The unit will automatically adjust and store the tension-zero value one second after the button is pressed.
- Page 8 CALIBRATION AND ZERO continued... Remove the weight and observe the output. It should read 0 VDC or 4 mA with nothing touching the tension sensing roller. Calibration weight percentage is 25% of full scale. The TA1 is running normally when the status LED is showing a solid green. If it is not staying on and is blinking, refer to the list of blink sequences indicating errors.
- Page 9 TROUBLESHOOTING Normal Operation = Solid Green 1 BLINK = No Calibration Performed Action Required: Perform Calibration. TA1 is not factory calibrated. A calibration must be performed at the customers site. Each calibration is specific to the installation configuration. If using CAL B – a separate calibration must be performed. 2 BLINKS = Outside Cal Range Once calibrated the TA1 will indicate an over range or under range condition by setting the error code to ‘Outside Cal Range’...
