INVALID DATA ENTRY

"BAD STEP INPUT"

** RE-ENTER **

Figure IV-16

The

ENTER

key is used to step from the start step entry to the end step entry. Repeated pressing

of the

ENTER

key will allow the user to move back-and-forth between the start and end entries and

change them as required until the correct start and end step values have been entered. The selected

speed set, and the start and end steps values entered, will be retained in EEProm memory for use

the next time the viscometer is powered up in the stand-alone mode. Pressing the

OPTION/TAB

key

at this point results in the following screen display:

LOCKOUT OPTIONS

1 = Enable Lockout
3 = Disable Lockout

Figure IV-17

S

LOCKOUT OPTIONS

Pressing the “1” key locks out any use of the NUMERIC keys, and the PROGRAM, SELECT

SPINDLE and OPTIONS/TAB keys. Pressing the “3” key would disable an existing lockout

condition only when in the LOCKOUT OPTIONS screen, Figure IV-17. After pressing the “1” or

“3” keys the user would be returned to the display of Figure IV-15. From Figure IV-15 the user

runs the program by pressing the PROGRAM RUN key which signifies that the user is satisfied

with his start and stop step values, and wishes to start running with the selected speed set. Or, he

can return to the default screen of Figure II-3 by pressing the MOTOR ON/OFF/ESCAPE key.

(Note: the OPTIONS/TAB key is re-enabled at this point only to allow the user to return to the

LOCKOUT OPTIONS screen). In either case, if the user has enabled the lockout mode, the top

line of the default display will change as shown in Figure IV-18 below:

RPM: 0.0 LK SPDL:31
TEMP: 72.1°F PRTO
SPEED SET 2 SELECTED
TORQUE = 00.0 %

Figure IV-18

The “LOCKOUT” condition will remain in effect until the user re-starts the program mode by

pressing the

PROGRAM RUN

key re-initiating the steps of Figures IV-15 through IV-18 above.

Once the start and end steps have been selected, the program is started by pressing the PROG

RUN key. However, if the viscometer motor was not turned on, the following message would be

displayed:

MOTOR MUST BE TURNED

ON PRIOR TO RUNNING

PROGRAMMED SPEEDS.

Figure IV-19

At this point, the user would turn the viscometer motor on by pressing the MOTOR ON/OFF/ESCAPE

key. This will cause the viscometer to start running at the first selected program speed.
