CONT (Continuous)
Press “MODE” button until “CONT” LED is illuminated.
This mode of operation is ideal if the user wants the test
stand to repeatedly cycle up and down continuously or
for a user-programmed number of times. The stand will
start in either direction depending on whether “PUSH”
or “PULL” is selected.
To begin programming the test stand, press the “SET”
key; the display will indicate a “C” in the “No” box. The
“C” designates that the digits programmed into the
adjacent LED’s will determine the number of cycles (number
of times) a program will run. Using the “TIME/#” and
the “RST/!” buttons, select the number of cycles you
want the program to complete (0001-9999) or select four
“0’s” if you want the program to run continuously; press
“SET” to store the number of cycles.
The letter “Ft“ appears in the LED’s in the “No” box; this
informs the user that the upper force limit should be
programmed. Use the “TIME/#” and “RST/!” buttons to
select the desired force limit. Use “TIME/#” to change
digit position and “RST/!” to increment each digit until
the desired limit force is displayed. NOTE: Pressing the
“TIME/#” button until no digits are blinking allows the
user to select a negative sign by pressing the “RST/!”
button. With no negative sign displayed, the test stand
platform is programmed to move downward (this denotes
compression). With the negative sign displayed, the test
stand platform will move upward (this (-) denotes tension).
Press “SET” to store the upper force limit in memory. The
down arrow LED (Fu) will light indicating that the test
stand is ready to have its lower force limit programmed.
Program the force limit using the “TIME/#” and “RST/!”
buttons. Use “TIME/#” to change digit position and
“RST/!” to increment each digit until the desired limit
force is displayed. NOTE: The upper limit must be greater
than the lower limit (F
upper
>F
lower
; -5>-20). Again press
“SET” to store the lower force limit into memory.
You may delay the time between upward and downward
movements by selecting 0, 1, 2, 3, 4 or 5 seconds using
the “TIME/#” button. You may view distance traveled
by pressing “LENGTH/SPEED/CYCLE” until the LED
adjacent “LENGTH” is lit. Speed can be displayed by
pressing “LENGTH/SPEED/CYCLE” until the LED adjacent
“SPEED” is lit. Finally, the number of cycles completed
can be displayed by pressing “LENGTH/SPEED/CYCLE” until
no LED’s are lit.
The test stand will move downward or upward after
automatically zeroing the force value of a 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.
Length, speed or cycle count can be displayed as
described in the “SING (Single)” section on page 6.
NOTE: An RS232C output is produced when using this mode
of operation, refer to “RS232C Output Format” on page
8 for details.
PROG (Program Operation)
Press the “MODE” key until the LED adjacent to “PROG”
is lit.
NOTE: An RS232C output is produced when using this
mode of operation, see “RS232C Output” section on
page 9 for details.
Before programming the stand, it is best to get the two
speed levels set appropriately. One should be set for the
speed the user wants their test performed at and the
other should be set at the highest acceptable level to have
the stand moving when not performing the actual force
test (this is usually at the maximum the stand will allow).
To begin programming the test stand, press the “SET”
key; the display will indicate a “C” in the “No” box. The
“C” designates that the digits programmed into the
adjacent LED’s will determine the number of cycles
(number of times) a program will run. Using the “TIME/#”
and the “RST/!” buttons, select the number of cycles
you want the program to complete (0001-9999) or select
four “0’s” if you want the program to run continuously.
Press “SET” to go to the next step.
See the “Setting a Force Limit” section on page 6 for
force limit programming details.
The display in “No” box now shows “H”; the “H”
designates the home position. Select the “PUSH” or
“PULL” button to set the HOME position; press “SET”.
The test stand platform will automatically move to the
appropriate (manually set) distance limit position.
The display in “No” box now shows “F”; the “F” designates
the auto zero function. This function is only available
when using the FGV or DRI Shimpo force gauges. Use
the “TIME/#” and “RST/!” buttons to program the “zero”
force.
NOTE: The recommended minimum zero force that the
user should program into the test stand is 0.2% of the
full scale (rating of the force gauge), i.e. if the
programmer is using an FGV-200H force gauge, the
programmed “zero” force should be 0.4 lb (0.002 X 200
= 0.4). If no force is programmed in this step and the
display reads all zeros, the test stand will not zero the
distance and this feature is inoperative. Press the “SET”
button to move on to the next step. This very useful
function allows the operator to reset the distance display
and RS232 output data to zero once the force gauge
senses a force measurement.
