loosening, repositioning, and re-tightening the thumb screws.
Note: the distance between limit switches must be at least 0.2 in [5 mm].
6.3.3 Overload Protection
The 09-1143 cable is required for overload protection of a Mark-10 gauge. If
overload protection is enabled, the test stand will stop when the programmed
percentage of full scale of the gauge has been reached.
When overload protection is enabled, if the 09-1143 cable is disconnected, and/
or if the force gauge is turned off, the error message GAUGE ERROR will
appear. Plug in the cable and/or turn on the force gauge to clear the message.
Note: For force test stands, when the crosshead is moving in the UP direction,
only the tension overload setting applies. When the crosshead is moving in the
DOWN direction, only the compression overload setting applies. The same
concept applies to the CW and CCW directions for torque test stands.
6.4 Auto Return Mode
With this setting, the test stand moves to a limit switch, load set point, or travel
distance (TSTM / TSTMH only), whichever occurs first, and stops. Then, the
test stand returns at maximum speed to the other limit, whichever occurs first,
and stops. The speed at which the test stand travels is dictated by the
independent speed settings.
The test stand can be stopped at any time during an Auto Return sequence by
pressing STOP. To resume the test, press UP or DOWN.
If the test stand has stopped at a load set point or travel distance set point, the
limit condition may be overridden by pressing and holding UP or DOWN for two
seconds.
Travel indication and limit switch operation is the same as in Basic Mode
.
6.4 Cycling Mode
This mode cycles the test stand between limit switches, load set points, or
travel distance set points (TSTM / TSTMH only), whichever occurs first. One
cycle consists of the following steps:
1. Test stand moves to a limit at the specified speed.
2. Test stand stops for the specified amount of dwell time.
3. Test stand reverses direction, returns to the other limit at the
specified speed, and stops.
A cycling sequence can be initiated from any position and can start in either
direction. If the test stand is at a limit, however, cycling can only be started in
the direction of the other limit. To initiate a cycle sequence, press UP or DOWN.
During a cycle sequence, a counter will be displayed, indicating the number of
cycles remaining, as shown below:
