button enters the value into the unit’s internal memory and takes effect
immediately. Also the “E” button can be used to exit self-test.
PRESCALE “PS”: Available only on a dual preset unit. When the “PS” button
is pressed, the prescale value can be programmed (See Program Prescale
Value). This value remains displayed for approximately 10 seconds after the
button is released.
INPUT CONFIGURATION & FRONT PANEL
RESET, DIP SWITCH SET-UP
The DIP switches are located at the rear of the unit. DIP switches 1 to 3
configure the type of input signal, and DIP switch 4 enables or disables the front
panel reset button. Refer to the block diagram of the unit for the details of count
and control circuitry.
SWITCH SET-UP
S1 - SNK.: Provides a 7.8 K
Ω
pull-up resistor for sensors with sinking outputs.
SRC.: Provides a 3.9 K
Ω
pull-down resistor for sensors with sourcing
outputs.
S2 - HI FRQ.: Removes damping capacitor and allows operation up to the
maximum frequency (See max count rates in specifications).
LO FRQ.: Connects damping capacitor for switch contact de-bounce.
Limits count speed to 100 cps. Minimum count ON/OFF times - 5
msec.
S3 - HI BIAS: Sets input trigger levels at mid-range, to accept outputs from 2-
wire proximity sensors, resistive photo-cells, and logic pulses with
full 0 to +12 V swings. (V
IL
= 5.5 V, V
IH
= 7.5 V).
LO BIAS: Sets input trigger levels to the low range, to accept logic pulses
with 0 to +5 V swings. (V
IL
= 1.5 V, V
IH
= 3.75 V).
S4 - DIS.RST.: Disables front panel reset.
EN. RST.: Enables front panel reset.
POWER-UP DIAGNOSTICS
Upon applying power, the Lynx counters perform an internal self-diagnostic
test of all the stored data. If the tests do not agree, a “P” appears on the right side
of the display. Normal operation of the unit will continue while the “P” is
displayed. Press the “E” button to remove the “P” and check all data set-up
values to be certain they are correct.
EMC INSTALLATION GUIDELINES
Although this unit is designed with a high degree of immunity to
ElectroMagnetic Interference (EMI), proper installation and wiring methods
must be followed to ensure compatibility in each application. The type of the
electrical noise, source or coupling method into the unit may be different for
various installations. The unit becomes more immune to EMI with fewer I/O
connections. Cable length, routing and shield termination are very important
and can mean the difference between a successful installation or a troublesome
installation. Listed below are some EMC guidelines for successful installation
in an industrial environment.
1. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in order
of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the unit and leave the other end of the
shield unconnected and insulated from earth ground.
2. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
3. Signal or Control cables within an enclosure should be routed as far away as
possible from contactors, control relays, transformers, and other noisy
components.
4. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional protection.
Install line filters on the power input cable to the unit to suppress power line
interference. Install them near the power entry point of the enclosure. The
following EMI suppression devices (or equivalent) are recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC #FCOR0000)
TDK # ZCAT3035-1330A
Steward #28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC #LFIL0000)
Schaffner # FN670-1.8/07
Corcom #1VR3
Note: Reference manufacturer’s instructions when installing a line filter.
5. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
6. Switching of inductive loads produces high EMI. Use of snubbers across
inductive loads suppresses EMI.
Snubbers:
RLC #SNUB0000
WIRING CONNECTIONS
All conductors should meet voltage and current ratings for each terminal.
Also cabling should conform to appropriate standards of good installation, local
codes and regulations. It is recommended that power supplied to the unit (AC
or DC) be protected by a fuse or circuit breaker.
When wiring the unit, remove the terminal block and use the numbers on the
label to identify the position number with the proper function. Strip the wire,
leaving approximately 1/4" bare wire exposed
(stranded wires should be tinned
with solder) . Insert the wire into the terminal and tighten down the screw until the
wire is clamped tightly. Each terminal can accept up to one #14 AWG, two #18
AWG or four #20 AWG wire
(s) . After the terminal block is wired, install it into
the proper location on the PC board. Wire each terminal block in this manner.
Caution : Terminal blocks should NOT be removed with power applied to the unit.
INPUT CONNECTIONS
Input connections are made on
terminal block TBA, refer to numbers
on the label to identify the position
number with the proper function.
(The input connections are the same
for single or dual preset counters.)
The use of shielded cable is
recommended. Follow the EMC
Installation Guidelines for shield
connection.
Terminal 1 - “REM.RST.” (remote
reset) When connected to common
a manual reset is performed. The
output(s) turn off
(if activated) and
the count display is reset. As long
as this terminal is low, the unit is
held at reset.
Terminal 2 - “PGM.DIS.” (program disable) When this terminal is not
connected to common, the following values can be programmed using the
front panel buttons:
Preset Value(s)
Prescale Value (if S9 is UP)
Decimal Point Position
Timed Output Value(s)
Outputs can also be tested during self-test under this condition (See Self-Test
description for further details). When connected to common, changing these
values and testing the outputs is no longer possible.
Terminal 3 - “UP/DN” (count direction control) When this terminal is not
connected to common, the count direction is “UP”. When connected to
common, the count direction is “DOWN”.
