7. If using a data acquisition system, start the program.
8. Confirm the controller is idle and in manual (MAN) mode by performing the steps below.
a. Press and hold the RUN/HOLD button for three seconds or longer. This will reset
and idle the controller. The RUN and HOLD indicators will extinguish.
b. Press the AUTO/MAN button to switch from automatic (AUTO) mode to manual
(MAN) mode. The MAN indicator will illuminate.
9. Select the proper ramp time in segment three (Seg.n 3) of the controller program to match
the rate desired. Additionally, select the target pounds-force value in segment three
(Seg.n 3), if the desired value is different than 48000 Lbf. DO NOT change any other
segment values.
To change the Seg.n 3 values;
a. Press the Page button until the Prog menu appears.
b. Press the Scroll button until the Segment number 3 is displayed (Seg.n 3).
c. Press the Scroll button.
d. Enter the segment type (tYPE). Use the Up/Down buttons to enter a ramp time
(rmP.t) type.
e. Press the Scroll button twice.
f. Enter the target setpoint (tGt). This is the 48000 at 4800 of the ramp, expressed in
units of Lbf/10. (For example, 48000 Lbf = 4800)
g. Press the Scroll button to display duration parameter (dur).
h. Enter the dur time (min) using the up button.
i. Press the Page button 4 times to exit.
Note: For low compressive strength samples 8.0-12.0 min is the recommended
duration. For high compressive strength samples 2.0-3.0 min is the
recommended duration.
10. Place the press direction control switch in the UP position.
11. Increase the controller output to 1.0% by pressing the UP arrow button. The press will
rise, contact the upper platen and stop. The press will then hold in an idle position for
20-30 seconds.
12. While the press is in idle decrease the controller output to 0.0% by press the DOWN
arrow button.
