MODE 8 LATCH OUTPUT AT PRESET 1 AND ZERO, MANUAL RESET TO PRESET 2
✝
The unit counts from preset 2, when preset 1 is reached,
output 1 turns on, and when zero is reached, output 2 turns
on. Counts continue to register after the outputs have
turned on. When a manual reset is performed, the count
resets to preset 2 and the outputs turn off.
MODE 9 TIMED OUTPUT AT PRESET 1 AND ZERO, MANUAL RESET TO PRESET 2
✝
The unit counts from preset 2, when preset 1 is reached,
output 1 turns on, and when zero is reached, output 2 turns
on. The outputs turn off at the end of their respective
programmed time values. Counts continue to accumulate after the outputs
have activated. When a manual reset is performed, the count resets to preset
2 and the cycle starts over.
MODE 10 OUTPUT 1 TURN OFF AT ZERO, LATCH OUTPUT 2 AT ZERO, MANUAL
RESET TO PRESET 2
✝
The unit counts from preset 2, when preset 1 is reached,
output 1 turns on. When zero is reached, output 2 turns on
and output 1 turns off. Output 2 remains on until a manual
reset is performed. Counts continue to accumulate after preset levels have
been reached. Manual reset turns off all outputs, if activated, and the count
resets to preset 2.
MODE 11 OUTPUT 1 TURN OFF AT ZERO, TIMED OUTPUT 2 AT ZERO, MANUAL
RESET TO PRESET 2
✝
The unit counts from preset 2, when preset 1 is reached,
output 1 turns on. When zero is reached, output 2 turns on
for the amount of time programmed and output 1 turns off.
Counts continue to accumulate after the preset levels have been reached.
When a manual reset is performed, the unit resets to preset 2.

- Prescale EN./DIS. Switch.
MODE 12 OUTPUT 1 TURN OFF AT ZERO, TIMED OUTPUT 2 AT ZERO, AUTOMATIC
RESET TO PRESET 2 AT ZERO
✝
The unit counts from preset 2, when preset 1 is reached,
output 1 turns on. When zero is reached, output 2 turns on
for the amount of time programmed, output 1 turns off, and
the unit automatically resets to preset 2.
MODE 13 TIMED OUTPUTS AT PRESET 1 AND ZERO, AUTOMATIC RESET TO
PRESET 2 AT ZERO
✝
✝
The unit counts from preset 2, when preset 1 is reached,
output 1 turns on. When zero is reached, output 2 turns on
and the count automatically resets to preset 2 and the cycle
starts over. The outputs turn off at the end of their respective programmed
time values.
MODE 14 OUTPUT 1 TURN OFF AT ZERO, TIMED OUTPUT 2 AT ZERO, AUTOMATIC
RESET TO PRESET 2 AFTER TIMED OUTPUT 2
✝
✝
The unit counts from preset 2, when preset 1 is reached,
output 1 turns on. When zero is reached, output 2 turns on
for the amount of time programmed and output 1 turns off.
At the end of timed output 2, the count automatically resets to preset 2 and the
cycle starts over.
MODE 15 TIMED OUTPUTS AT PRESET 1 AND ZERO, AUTOMATIC RESET TO
PRESET 2 AFTER TIMED OUTPUT 2
✝
The unit counts from preset 2, when preset 1 is reached,
output 1 turns on, and when zero is reached, output 2 turns
on. The outputs turn off at the end of their respective
programmed time values. At the end of timed output 2, the count
automatically resets to preset 2 and the cycle starts over.
✝
- When down count is desired, (such as reset to preset modes of operation)
the “UP/DN” terminal must be tied to the “COMM.” terminal.
MODES OF OPERATION FOR DUAL PRESET LYNX COUNTER (Cont’d)
SELF-TEST
The self-test feature can be activated without affecting the count, missing a
preset point, affecting the timed output durations, or interfering with control
functions. This test verifies that all digits operate. Also, the DIP switch settings
and the relay outputs can be tested.
If the outputs are not tested, the state(s) of the output(s) remain the same as
they were prior to self-test. If the outputs are tested in self-test, the outputs will
be 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, resets the unit.)
To enter self-test, press the two left-hand digit buttons (on the front panel)
simultaneously. At this time, the display will cycle all the digits on the display
each for about half a second and in the sequence shown below.

The next portion of self-test displays a group of four ones and zeros. The two
left-most digits always appear as zeros. The third digit represents the prescale
enable/disable DIP switch setting. With prescale enabled, the digit shows a
zero, and with it disabled the digit shows a one. The fourth digit represents
program disable (PGM.DIS). A zero represents a high at this terminal and a one
represents a low. A second set of digits are the settings of the mode select
switches (the four DIP switches located along the side of the unit). 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 do not affect counter operation immediately, but any
changes will take effect when self-test is exited. When the switch is “DOWN”,
the digit shows a one. When the switch is “UP”, the digit shows a zero.
During the time the mode switch settings are displayed, the outputs can be
tested. To activate the output(s), press “P1” for output 1 or “P2” for output 2. If
no testing of the output(s) is required, press the “E” button until the unit exits
self-test (the unit returns to normal display mode). Also, if no activity occurs on
the switches or the front panel button within 18 seconds after the unit pauses at
the mode switch display, the unit automatically exits self-test.
Note: The “PGM.DIS.” terminal must not be connected to common for the
outputs to be activated.
Caution
: The operator should use care when testing the outputs, so as not to
cause any undesirable or hazardous conditions in the system.
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)
Prescale Value
=
1.00000 (if a dual preset version)
Count Value
=
0
Timed Output Value(s)
=
0.10 second
DIP SWITCH SETTINGS
All switches are moved to the “UP” position except for the reset enable
switch, which is moved “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.
