MODES OF OPERATION
Mode settings of the switches are shown to the right of the text below.
The mode number corresponds to a binary code, represented by the DIP
switch positions. When a switch is "UP", it is equivalent to a zero. When
the switch is
'DOWN",
it is equivalent to a one. The mode switch settings
can be easily observed from the front panel by using the self-test. At the
end of the self-test, the state of these mode switches is displayed. The
mode selection DIP switches are located along the side of the unit's case.
NOTES:
1. For all the following modes of operation, when the unit is set for a Reset
to Zero mode, the UP/DN terminal
(count direction)
is normally deacti-
vated (open or at +5VDC maximum). When the unit is set for a Reset
to Preset mode, the UP/DN terminal is normally tied to common.
However, even though these are the usual conditions for the UP/DN
terminal, it does not have to operate in this fashion. (i.e.,
The unit can
count down in a Reset to Zero mode, or count up in a Reset to Preset
mode, and still maintain normal operating functions.)
2. The timed output must be less than the time required to count from the
reset condition to the preset point. Otherwise, the output will appear to
be latched-on.
MODES
OF
OPERATION FOR SINGLE PRESET LYNX COUNTER
MODE 0 LATCH OUTPUT AT PRESET, MANUAL RESET TO ZERO
In this mode, as the unit counts from zero, the output will
5 6 7 8
latch on when the preset is reached. When a manual reset*
occurs, the unit will Reset to Zero and the output, if latched
on, will unlatch. Counts will continue to accumulate after the output has
turned on.
MODE 1 TIMED OUTPUT AT PRESET, MANUAL RESET TO ZERO
In this mode, as the unit counts from zero, the output will
5 6 7
8
turn on when the preset is reached. The output will turn off
after its programmed time value has occurred. When a man-
ual reset occurs, the unit will Reset to Zero. Manual reset* will termi-
nate the timed output, if the output is still activated. Counts will con-
tinue to accumulate after the preset level has been reached.
MODE 2 & 3 - * *
MODE 4 TIMED OUTPUT AT PRESET, AUTOMATIC RESET TO ZERO AT PRESET
In this mode, as the unit counts from zero, the output will
turn on when the preset is reached. At the same time, th
unit will automatically Reset to Zero and start the cycle over
again. The output will turn off after its programmed time va as
occurred. Manual reset* will turn off the output, if turned on, and reset
the count to zero. During automatic reset, no counts will be lost if the
count rate does not exceed the maximum count rate specified.
MODE 5 - *
1=1-
MODE
6
TIMED OUTPUT AT PRESET, AUTOMATIC RESET TO ZERO AFTER THE
TIMED OUTPUT
In this mode, as the unit counts from zero, the output will
5 6 7 8
turn on when the preset is reached. The output will turn off
after its programmed time value has occurred. At the end of
the timed output, the unit will automatically Reset to Zero and start the
cycle over again. During automatic reset, no counts will be lost if the
count rate does not exceed the maximum count rate specified. Manual
reset* will turn off the output, if turned on, and reset the count to zero.
MODE 7 - *
-
Manual reset, either by front panel reset
(if
enabled) or remote reset, is
always active, and will override any condition or state the counter is
presently in.
MODE 6 LATCH OUTPUT AT ZERO, MANUAL RESET TO PRESET t
In this mode, as the unit counts from preset, the output will
latch on when zero is reached. When a manual reset* occurs,
the unit will Reset to Preset and the output, if latched on, will
unlatch. Counts will continue to register after the outputs turn on.
MODE 9 TIMED OUTPUT AT ZERO, MANUAL RESET TO PRESET t
In this mode, as the unit counts from preset, the output will
5 8 7 8
turn on when zero is reached. The output will turn off after
its programmed time value has occurred. When a manual re-
set* occurs, the unit will Reset to Preset. Manual reset will terminate
the timed output, if the output is still activated. Counts will continue to
accumulate after the output has activated.
MODE 10
& 11- **
MODE 12 TIMED OUTPUT AT ZERO, AUTOMATIC RESET TO PRESET AT ZERO t
In this mode, as the unit counts from preset, the output will â
7
turn on when zero is reached. At this time, the unit will
automatically Reset to Preset. The output will turn off after
î
its programmed time value has occurred. Manual reset* will turn off
the output, if turned on, and reset the count to preset. During automat-
ic reset, no counts will be lost if the count rate does not exceed 2,500cps.
MODE 13 - * *
MODE 14 TIMED OUTPUT AT ZERO, AUTOMATIC RESET TO PRESET AFTER THE
TIMED OUTPUT
t
In this mode, as the unit counts from preset, the output will
turn on when zero is reached. The output will turn off after
its programmed time value has occurred. At the end of the
timed output, the unit will automatically Reset to Preset and start the
cycle over. During automatic reset, no counts will be lost if the count
rate does not exceed the maximum count rate specified. Manual reset*
will turn off the output, if turned on, and reset the count to preset.
MODE 15 - *
* * - These modes are not applicable to the single preset Lynx counter
(they are used only for the two preset counter unit).
t -
When down count is desired, (such as reset to preset modes
of
oper-
ation) the "UP/DN" terminal must be tied to the "COMM." terminal.

MODES OF OPERATION FOR DUAL PRESET LYNX COUNTER
MODE 0 LATCH OUTPUTS AT PRESET, MANUAL RESET TO ZERO
In this mode, as the unit counts from zero, output 1 will
latch on when preset 1 is reached, and output 2 will latch on
when preset 2 is reached. When a manual reset* occurs, the
unit will Reset to Zero and the outputs, if latched on, will unlatch.
Counts will continue to accumulate after outputs have turned on.
* -
Manual reset, either by front panel reset
(if
enabled) or remote reset, is
always active, and will override any condition or state the counter is
presently in.
MODE 1 TIMED OUTPUT AT PRESET, MANUAL RESET TO ZERO
In this mode, as the unit counts from zero, output 1 will
5 6 7 8 9
turn on when preset 1 is reached, and output 2 will turn on
when preset 2 is reached. The outputs will turn off after their
respective programmed time values have occurred. When a manual
reset occurs, the unit will Reset to Zero. Manual reset* will terminate
the timed outputs, if the outputs are still turned on. Counts will con-
tinue to accumulate after the preset levels have been reached.
