FRONT PANEL FUNCTION DESCRIPTION
These units employ six front panel buttons for control and data entering. The
button functions are described below.
RESET “R” - This button resets the counter to either zero or preset, depending
on the mode of operation selected. For this button to operate, the
enable/disable reset button switch, at the rear of the unit, must be set to the
enable
(EN) position. This button is also used in conjunction with the two
preset buttons (one button on the single preset unit) to view and change the
timed output value. (When reset is activated, all processes are stopped or
interrupted. I.E. outputs turn off, count stops, display is halted, etc.) This is
the case under any mode of operation, in any data entry mode.
PRESET “P1” (“P2”) - The preset buttons are labeled and are the two left-
hand buttons of the top row, located on the front of the unit. (For the single
preset unit, the left-most button is the preset button.) When the “P1” button
is pressed, preset 1 is displayed. When the “P2” (if available) button is
pressed, preset 2 is displayed. These values will remain displayed for
approximately 10 sec. after release of the button. Also, the preset buttons are
used in conjunction with the reset button, to view and change the timed
output values.
(See “To Enter A New Timed Output Value” section.)
ENTER “E” - This button is used in the “Preset Enter” mode and in the “Timed
Output Enter” mode. After the desired value is obtained on the display, this
button is pressed which then enters the value into the internal processor. This
new value, at that instant, is used in the processing of preset or timed output
values.
“E” is also used at the end of self-test to exit self-test.
TO ENTER A NEW PRESET VALUE
FIRST : Press “P1” (or “P2”, if a two preset unit) . This will display the
respective preset value and it will remain displayed for approximately 10 sec.
after release of the last button pushed.
(At this time, preset display mode can
be exited without change, by pressing the “E” button.)
SECOND: Once the preset value is displayed, changing the digit value can be
done by pressing the button directly beneath the digit position to be changed.
(This value cannot be changed when “PGM. DIS.” is activated.) Each time
the button is pressed, the digit will increment by one. Also, pressing and
holding the button will continuously scroll the digit from 0 through 9, then
back to 0 again. When the desired value for that digit is reached, release the
button. Do this for all the digits to be changed.
THIRD: Press the “E” (Enter) button to enter the value into the unit’s memory.
As soon as the “E” button is pressed, this new value is used as the operating
data. This means, if the preset value is entered, and the old or new value has
not been reached, the new value will be used without process disruption
(Preset on the fly). If the “E” button is not pressed within 10 sec. after the
last digit has been changed, the value will disappear (go back to normal
display mode) and the unit will continue to operate on the previous value.
During the displaying, changing, and entering of a new preset value, all
functions of the unit are operational, such as, counting, resetting, outputs
firing, etc.
Note: For RTP modes of operation, “P1” (“P2” for dual preset
units) will determine the “Start Count” value of each cycle.
TO ENTER A NEW TIMED OUTPUT VALUE
FIRST: Press and hold the “P1” (or “P2”, for two preset units) button and then
press the “R” (Reset) button. At this time, the respective timed output value
will be displayed and will remain displayed for approximately 10 sec. after
release of the last button pushed.
(At this time, the timed output display mode
can be exited without change, by pressing the “E” button.)
SECOND: Once the timed output is displayed, changing the digit value can be
done by pressing the button directly beneath the digit position to be changed.
(This value cannot be changed when “PGM. DIS.” is activated.) Each time
the button is pressed, the digit will increment by one. Also, pressing and
holding the button will continuously scroll the digit from 0 through 9, then
back to 0 again. When the desired value for that digit is reached, release the
button. Do this for all the digits to be changed.
(This value can be set between
0.01 sec and 99.99 sec.)
THIRD: Press the “E” (Enter) button to enter the value into the unit’s
memory. As soon as the “E” button is pressed, this new value is used as the
operating data. If the “E” button is not pressed within 10 sec. after the last
digit has been changed, the value will disappear (go back to normal display
mode) and the unit will continue to operate on the previous value. During
the displaying, changing, and entering of a new timed output value, all
functions of the unit can be done, such as counting, resetting, output firing
etc. without any interruption.
INITIAL POWER-UP & FACTORY SETTINGS
When the unit is shipped from the factory, the values and the following
modes are set as shown.
Preset 1 = 500
Preset 2 = 1,000 (if a dual preset version)
Count value = 0
Timed output value (s) = 0.1 second
DIP SWITCH SETTINGS
All switches are in the “UP” position except for the reset enable switch,
which is “DOWN” . With the switches set in these positions, the unit is
operating in mode zero (latch-on at preset, manual reset to zero) . The input is
set for sinking type inputs, high frequency, and high bias operation.
TROUBLESHOOTING
For further technical assistance, contact technical support at the appropriate
company numbers listed.
SELF-TEST
This unit has a built-in, self-test feature, which can be activated without losing
counts, preset values, missing preset points, timed output durations, or interfering
with control functions. With this test, all digits are cycled through, then the mode
select switch settings are displayed. At this point, the outputs can also be tested.
To enter self-test, press the two upper right-hand digit buttons (located on the
front panel) , simultaneously. At this time, whatever count value was displayed
will disappear and be replaced by a string of four zeros. This will be shown for
about half a second, then a string of ones will appear for the same time duration.
Following these, a string of twos and so on, up to nine will be displayed. After the
nines are shown, three decimal points will appear. After this portion, an interlace
pattern of the same numbers will be shown. First, a combination of 1, 0, 1, 0 then
1, 2, 1, 2 and so on, until all digits from zero to nine have been displayed.
The next portion of self-test will display a group of ones and zeros. These
ones and zeros are the settings of the mode select switches (the four right-hand
DIP switches only) . This pattern directly corresponds to the number
representing the mode of operation. If the switches are changed while at this
point in the self-test, the settings can be seen to change. These changes will not
affect counter operation immediately, but any changes will take effect when
self-test is exited. When the switch is
“DOWN” , the display will show a one.
When the switch is “UP” , the display will show a zero. If no testing of the
outputs is required, press the “E” button until the unit exits self-test (the unit
will go back to the count display mode) . Also, if no activity occurs on the
switches or the front panel buttons within 18 sec. after the unit pauses at the
mode switch display, the unit will automatically exit the self-test.
During the time the mode switch settings are displayed, the outputs can be
tested. To activate the outputs, press the “P1” button (for dual preset version,
“P1” or “P2” is pressed) .
Note: The “PGM. DIS.” terminal must be at a high level for the outputs to be
activated. Also, caution should be used when testing the outputs, so as not to
cause any undesirable or hazardous conditions in the system. (To turn off the
outputs, release the button.)
If the outputs are not tested, the state of the outputs will remain the same as
it was prior to self-test. If the outputs are tested in self-test, the outputs will be
turned off after exiting self-test.
Rapid advance of the self-test routine can be done by pressing and releasing
any of the front panel buttons except for the “R” button. (Pressing “R” at any
time, except when entering the timed output mode, will reset the unit.)
