5.4 Basic mode
The crosshead moves upward when UP is pressed, and downward when DOWN is pressed. When the
crosshead is in motion, an LED indicator on the button pushed will be illuminated. The KEYS setting
controls how crosshead movement responds to the push of either of the directional buttons. The three
settings are:
1. Maintained
The crosshead will move continuously once the button has been pressed. Subsequently
pressing STOP will stop crosshead motion.
2. Momentary
The crosshead will move only if the button is pressed and held. Releasing the button will
stop movement immediately.
3. Auto (default)
Holding down the button for more than 0.5 seconds will enter Momentary mode, at which
time an audible indicator will sound and the LED indicator on the button pushed will be
illuminated. A short tap on the button will operate the test stand in Maintained mode.
Pressing STOP during Maintained mode will stop crosshead motion. To resume the test,
press UP or DOWN again.
Pressing EMERGENCY STOP will immediately stop crosshead motion in any mode. To release, twist the
button clockwise until it assumes its original position. To resume the test, press either directional button
for two seconds.
Crosshead movement will take place until a limit has been reached. If the crosshead has stopped at a
soft limit, the limit condition may be overridden by pressing and holding either directional button for two
seconds.
5.4.1 Travel indication
If installed, the position is displayed in the upper left corner of the display. The unit of measurement is
dictated by the UNITS function. To zero the value, press the Zero Travel key. The position will be
retained during power cycles.
5.4.2 Limit switch operation
Limit switches allow the operator to set a location along the column at which point the crosshead will stop
moving. Adjust their positions by loosening the thumb screws, repositioning, and re-tightening the thumb
