Frame Motion Delays: Delays are sometimes needed between the control input and the resulting action
in order to protect the hardware. In most cases, the unload value is not used and the box is left clear.
The unload time at the end of the test is the amount of time that the drawhead will run to remove the
load at the end of the test. The time must be long enough to fully remove the load; however, the time
must not be excessive or damage can result to the tester, load train, extensometer, or furnace.
On frames with motorized drawheads or elevators, a manual control delay is essential. If the motor has
not stopped before the reverse motion command is given, the motor may continue to run in the original
direction. If both commands are given simultaneously, the motor may be drawing excessive current and
will be damaged. This can also cause protective devices to open. To avoid these issues, a three-second
delay is normally used. When a reverse direction is specified, the frame motion controls on the system
console will be inactive for three seconds, allowing the motor time to stop and reverse safely.
NOTE: A casual operator may be unaware that this delay is a safety measure rather than a sign of
equipment malfunction. It is essential for operators to understand this safety feature.
