POWER REQUIREMENTS:
Available in 4 voltage ranges. 115VAC
( + /10%), 230VAC (
+ /-10%),
50/60Hz, 6VA; 11-14VDC; or 21.5-
30VDC.
3.
SENSOR POWER:
+ 12VDC (
+ /-25%) @
100mA.
4.
COUNT INPUT: Switch selectable to accept count pulses from a variety
of sources, including switch contacts, outputs from CMOS or TTL cir-
cuits, and all standard RLC sensors.
Current Sourcing: Unit provides 3.9K pull-down load for sensors with
current sourcing outputs.
(Max. input voltage, 28VDC @ 7mA.)
Current Sinking: Unit provides 7.8K pull-up load for sensors with cur-
rent sinking outputs.
(Max. sensor current, 1.6mA.)
Debounce: Damping capacitor provided for switch contact debounce.
Limits count speed to 100cps max. and input pulse widths to 5msec.

PRESCALE VALUE RANGE: 0 to 9.99999
(two preset unit only).
6.
MAXIMUM COUNT RATES:
High Frequency: For the single preset unit only - 2500cps maximum
square wave input for all electronic sensors, under all modes of oper-
ation.
For dual preset units, the following chart lists the count rates for all the
possible prescale values.

Low Frequency:
both single and dual preset units - 100cps for switch
contact closures.
NOTE: These units will operate with VCM (E-H)
modules.
7.
CONTROL INPUTS:
Remote Reset:
Activate low
(
V
IL
= .
5V max.), internally pulled up to
5VDC through a 10Kohm resistor (Ism
(
= .5mA). Response time =
10msec. A low will reset the unit and deactivate outputs.
Program Disable:
Active low
(
V
IL
= .
5V max.), internally pulled up to
5VDC through a 10Kohm resistor (Ism
(
= .5mA). A low will inhibit
the changing of presets, prescale, and timed outputs, as well as testing
outputs in self-test.
Up/Down Control: Active low = .5V max.), internally pulled up to
5VDC through a 10Kohm resistor
(ISNK
=
.5mA). Response time =
150usec. This input determines the direction of the count, and is
independent of Reset to Zero or Reset to Preset modes of operation.
When input is low, count is down.
8.
OUTPUTS:
Solid-State: Current sinking NPN Open Collector Transistors.
I
SNK =
100mA max.,
V
OH
=
30VDC max.,
Vo
l
_ = 1V @
100mA. One solid-
state output for each preset level.
Relays: Form C contacts rated 6amps @ 120/260VAC, 28VDC
(resistive
load),
1/8H.P. @ 120VAC
(inductive load).
One relay output for
each preset level. The operate time is 5msec. nominal and the release
time is 3msec. nominal.
Programmable
Timed Output: The timed output can be programmed
from .Olsec. to 99.99sec.,
+ 1-(1% + lOmsec.).
The timed output is set
for .1sec. at the factory.
9.
MEMORY RETENTION:
The Lynx Counters have a "no power
E
2
PROM", which maintains all information when the AC power is
removed. The life expectancy of this device is at least 10,000 power
down cycles, and length of memory retention for a single power down
can be as long as 10 years.
10.
INPUT, POWER, AND OUTPUT CONNECTIONS: There are two
plug-in, compression type, barrier strips located at the rear of the unit.
These strips can be removed from the rear of the unit for ease of wiring.
After wiring is complete, the connector can be plugged back into the
unit.
11.
OPERATING TEMPERATURE RANGE:
0°C to 50°C.
12.
STORAGE TEMPERATURE RANGE:
-40°C to 70°C
13.
CONSTRUCTION: Black plastic front bezel with black plastic insert.
Front panel meets NEMA 4 requirements for wash-down and dusty
environments, when properly installed. (Panel gasket and mounting clip
included with unit.)

WEIGHT: .8 lbs.
SELECTION OF INPUT SET-UP & MODES
OF
OPERATION
The selection of Input Set-up is accomplished by four DIP switches,
located at the rear of the unit, in the upper right-hand corner. DIP
switches 1-3 are used to configure the input, and DIP switch 4 is used to
enable or disable the front panel reset button. The modes of operation are
selected by four DIP switches located along the side of the unit. The input
set-up and reset enable switches will be discussed first. Refer to the block
diagram of the unit for the details of count and control circuitry.
