General Operation
Three phases of operation are repeated for each joint:
1.
Idle: showing the measurement mode and target; waiting for torque.
2.
Torque Applied: showing the Measurement Screen.
3.
Torque Released: showing the Measurement Screen and waiting to clear.
Idle Screen
As shown below, the Idle Screen is somewhat different for each mode. Residual mode doesn
’t show target values. The
target angle, not torque, is shown for T2A mode. Angle values are shown white-on-black.
Measurement Screen
•
When torque is applied, the Measurement Screen replaces the Idle Screen.
•
The large digits show the current peak torque or angle depending on the mode.
•
The current angle of rotation is shown white-on-black.
•
Status is shown for torque and for angle
–
OK, HI, or LO. (The target icon disappears.)
•
Direction of measured torque is shown (clockwise or counterclockwise arrow).
•
When torque is released, the digits show the final torque and angle measured. At the auto-clear timeout, the Idle
Screen is shown again
or “TOOL DISABLED” will be displayed if the batch is complete and lock on batch is active
.
MODES
Settings Per Mode
The meaning of some settings may change depending on mode.
Peak Mode
Peak mode shows the current peak torque on the tool until torque is released. Torque display begins at 4% of full scale
torque capacity. Yellow LEDs light up in sequence as minimum torque is approached.
•
Target Torque
–
Apply torque to this value to get a green LED.
•
Minimum Torque
–
This is the minimum acceptable torque for the joint. The light band will be yellow and status
OK when this value is met. If torque is between the minimum and maximum settings, it will turn green when
torque is released and the dwell timer has expired.
•
Maximum Torque
–
The light band will turn red and status HI if the peak value exceeds this setting.
Residual Mode
Residual mode shows zero torque on the tool until residual torque is detected, then it shows the residual torque until
torque is released, with an OK status.
•
Target Angle
–
The default is 3°. To look for the torque dip only, set the target angle to 0°.
Two methods may be applied to detect residual torque.
•
On a soft joint, apply torque through a small prescribed angle that denotes residual torque has been reached. The
value at that exact angle represents the residual torque that was in the joint. A minimum of 3° is recommended
but may be adjusted to reflect joint behavior.
•
On a hard joint, a dip in torque may be detected when the applied torque breaks the joint loose momentarily. The
value at the bottom of the dip represents the residual torque that was in the joint.
Torque To Angle (T2A) Mode
In T2A mode, a joint is tightened to a prescribed target torque. Then the fastener is turned through an additional angle,
intended to stretch the fastener and thus apply clamp load by an amount proportional to the angle.
