Operation
There are five modes of operation: MANU (Manual),
JOG (Jog), SING (Single). CONT (Continuous) or
PROG (Program). The user can select one of these
modes by pressing the “MODE” button until the desired
mode of operation is illuminated.
It is possible to restrict the range of travel with manual
limits. To manually adjust distance limits, loosen each of
the two set screws holding the limit switch brackets; these
set screws/brackets prevent the force gauge or load cell
platform from traveling by activating internal limit
switches. Adjust the top set screw/bracket to set the
upper distance limit and the bottom set screw/bracket
to set the lower distance limit.
Setting a Force Limit
It is possible to set one force limit when using a Shimpo
DFS, DRI or FGV force gauge with the appropriate cable
and operating the test stand in the manual, jog, single,
and program mode. To program a force limit (when in
one of these modes), press the “SET” button on the front
panel display. Note that the display “No” box shows
“Fv”. The “F” and the two arrows inform the user that
he will be programming a force limit. Use the “TIME/#”
to change digit position and “RST/!” to increment each
digit until the desired limit force is displayed. Press the
“TIME/#” button until no digits are blinking. This allows
the user to select a negative sign by pressing the “RST/!”
button. With no negative sign displayed, the test stand
force limit is programmed as a compression force limit;
with the negative sign displayed, the test stand force
limit is programmed as a tension force limit. Press “SET”
to store the force limit in memory.
The manual, jog, and single modes share the same
programmed force limit.
Two force limits can be set when operating in the
continuous mode. The instructions for programming
two force limits are located in the Operation section under
CONT (Continuous) on page 7.
MANU (Manual)
Press “MODE” button until “MANU” LED is illuminated.
This mode of operation is ideal for manually recording
force measurements. The test stand will only operate
between the limits that are set by the test stand user.
These limits can be either manually adjusted (distance
limits) or programmed with force limits when a Shimpo
force gauge is used (see the “Setting a Force Limit” section
above for force limit programming details).
The test stand will move in the downward or upward
direction when the respective “PUSH” or “PULL” button
is selected. The stand will continue to move in the
selected direction until one of the following occurs: the
“STOP” button is pushed, one of the manual limit switches
is tripped, the emergency reset button is pushed or the
force limit is reached.
In this mode of operation the user can display length or
speed. Display length by pressing the “LENGTH/SPEED”
button until the LED adjacent “LENGTH” is illuminated.
To display speed, push the “LENGTH/SPEED” button until
the LED adjacent “SPEED” is illuminated.
NOTE: In this mode of operation, no RS232C output is
produced.
JOG (Jog)
Press MODE button until “JOG” LED is illuminated.
This mode of operation is identical to “MANU”, except
that the movement in any direction will only occur while
either the “PUSH” or “PULL” button is depressed.
See the “Setting a Force Limit” section (left) for force
limit programming details.
NOTE: In this mode of operation, no RS232C output is
produced.
SING (Single)
Press MODE button until “SING” LED is illuminated.
This mode of operation is ideal for completing one cycle
between manual distance limits and/or force limit. The
initial starting direction can be either in the tension or
compression direction depending on whether the “PULL”
or “PUSH” buttons are pressed.
See the “Setting a Force Limit” section (left) for force
limit programming details.
The test stand will move downward or upward after
automatically zeroing the force value of the Shimpo gauge
when the respective “PUSH” or “PULL” button is selected.
The stand will continue to move until one of the following
events occurs: the “STOP” button is pushed, one of the
manual limit switches is tripped, the emergency reset
button is pushed or the force limit is reached. If the stand
is stopped for any of these reasons, the gauge’s value will
be reset to zero once either the “PUSH” or “PULL” button
is pushed again to resume movement.
In this mode of operation, the user can display length,
speed or cycle count. Display length by pressing the
“LENGTH/SPEED/CYCLE” button until the LED adjacent
“LENGTH” is illuminated. To display speed, push the
“LENGTH/SPEED/CYCLE” button until the LED adjacent
“SPEED” is illuminated. Finally, to display cycle count,
press the “LENGTH/SPEED/CYCLE” button until there are
no LED’s illuminated. When the stand platform is moving
in the “down” direction, the LED next to “SPEED B” is
active; when the stand is moving in the “up” direction,
the LED next to “SPEED A” is active.
NOTE: An RS232C output is produced when using this
mode of operation; refer to “RS232C Output Format” on
page 9 for details.
