CODE 63 - SAMPLE TIME
The Gemini offers six different lengths of sample times. They are 1 second; 2
seconds;5seconds;10seconds;20seconds; and 50 seconds.Sample Timeisdefined
as the time period allowed for input pulses to accumulate. At the conclusion of this
time period, the number of pulses which occur during the sample time, is multiplied
by the programmed scale factor value and then displayed.
(For an explanation of
how to determine the proper sample time, refer to Appendix “E”)
.
[63 1]
SAMPLE TIME OF 1 SECOND
[63 2]
SAMPLE TIME OF 2 SECONDS
[63 3]
SAMPLE TIME OF 5 SECONDS
[63 4]
SAMPLE TIME OF 10 SECONDS
[63 5]
SAMPLE TIME OF 20 SECONDS
[63 6]
SAMPLE TIME OF 50 SECONDS
CODE 66 - “OPERATOR ACCESSIBLE FUNCTIONS” MODES
(PGM. DIS. Connected to “COMMON”)
The Gemini has four basic levels of
“Operator Accessible Functions”
.
However each of these levels can be modified to enable or disable manual reset.
When the
“PGM. DIS.” (program disable)
terminal is connected to
“COMMON”
, access to all functions is disabled except for those listed below
which will remain enabled. All of the function codes and parameters can be
interrogated, regardless of the
“Operator Accessible Functions”
mode selected.
A
“-”
sign in front of the mode identifier will disable reset and the absence of a
“-”
sign will enable the reset terminal and front panel reset button.
(Note: Front panel reset can be independently “Disabled” by using the disable
reset DIP switch.)
[66 1]
NO FUNCTIONS ENABLED EXCEPT RESET - In this mode, manual
reset is enabled, but none of the programming functions can be changed.
[66 2]
PRESET PROGRAMMING AND RESET ENABLED - In this mode,
manual reset and the programming of the Preset Values are enabled.
[66 3]
SCALE FACTOR PROGRAMMING AND RESET ENABLED - In this
mode, manual reset and the programming of the Preset values are enabled.
[66 4]
SCALE FACTOR, PRESET PROGRAMMING AND RESET
ENABLED - In this mode, manual reset and the programming of the Scale
Factor and Preset Values are enabled.
[66 -1]
[66 -2]
These Modes are the same as above with the
[66 -3]
exception that manual reset is disabled.
[66 -4]
PRESET VALUES
Whenever the count value equals the preset value, an output action will occur.
(This action depends on the previously programmed modes)
. The Preset Value may
vary from -999,999 to 999,999. Refer to
“Programming The Presets, Scale Factors,
And Timed Output Values”
section for instructions on entering the Preset Value.
The Scale Factor value will have a direct effect on the preset being entered. For
Scale Factors greater than one, the preset value should be an integer multiple of
the scale factor. If it is not, the Gemini will automatically adjust the preset value
up or down to force it to be evenly divisible by the scale factor.
“P”(1) - PRESET 1 VALUE
“P”(2) - PRESET 2 VALUE (GEMINI 2000 ONLY)
SCALE FACTOR
“SF”(3) SCALE FACTOR
- The internal count value is multiplied by the scale
factor value, which changes the displayed value accordingly. Scale factor is used
primarily for conversion from existing pulses per unit of measure to the required
displayed units. This includes conversion from different units of measure
(i.e.
feet to meters, etc.)
. The scale factor value may range from -5.9999 to 5.9999.
(Refer to “Programming The Presets, Scale Factor & Output Time Delays”
section for entering instructions.)
It is important to note that the precision of an application cannot be improved
by using a scale factor greater than one. To accomplish greater precision, more
pulse information must be generated per measuring unit. For example, if 5 pulses
are being received per foot of material, the precision of 10th of feet cannot be
attained by simply programming a 2.000 scale factor, even though the display is
reading in tenths. In this case, the display will increment by two for each count
input. Thus, if an odd preset value was entered, such as 6.7 ft., the Gemini will
alter the preset to read in even tenths of feet.
