The torque plate will rotate until a limit has been reached. If the test stand has stopped at a soft limit, the
limit condition may be overridden by pressing and holding either directional button for two seconds.
5.3.1 Travel indication
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 and hold the
STOP
key. The position will not be retained
during power cycles.
5.3.2 Overload protection
The available interface cable is required for overload protection of a Mark-10 torque sensor. If overload
protection is enabled, the test stand will stop when the programmed percentage of full scale of the
instrument has been reached.
When overload protection is enabled, if the cable is disconnected, and/or if the instrument is powered off,
an error message will appear. Plug in the cable and/or turn on the instrument to clear the message.
Note:
When the torque plate is rotating in the clockwise direction, only the clockwise overload setting is
active. When rotating in the counter-clockwise direction, only the counter-clockwise overload setting is
active.
5.4 Auto return mode
In this mode the torque plate rotates at the set speed to whichever limit it encounters first and stops.
Then, it returns at maximum speed to the opposite limit, whichever occurs first, and stops. Press either
directional button to initiate an Auto Return sequence.
The test stand can be stopped at any time during an Auto Return sequence by pressing
STOP
. To
resume the test, press either directional button.
Note:
If the test stand has stopped at a soft limit, the limit condition may be overridden by pressing and
holding either directional button for two seconds.
5.5 Cycling mode
This mode cycles the torque plate between limits, whichever occurs first. One cycle consists of the
following steps:
1. Torque plate rotates to a limit at the specified speed.
2. Torque plate stops for the specified amount of dwell time.
3. Torque plate reverses direction, returns to the other limit at the specified speed, and stops for
the specified amount of dwell time.
A cycling sequence can be initiated from any position and can start in either direction. To initiate a cycle
sequence, press either directional button. During a cycle sequence, a counter will be displayed, indicating
the number of cycles remaining, as shown below:
As in Basic Mode, the
min
,
max
, and
set
soft keys are active during test stand movement.
When the cycling sequence and the test stand has stopped at a
soft limit
, the limit condition may be
overridden by pressing and holding either directional button.
