CONNECTIONS & CONFIGURATION SWITCH SET-UPS FOR VARIOUS SENSOR OUTPUTS
1. SENSOR SUPPLY VOLTAGE AND CURRENT
The +12 V sensor supply voltage on the “DC OUT” Terminal is nominal
with ±25% variation due to line and internal load variations. All RLC sensors
will accommodate this variation.
2. HI/LO FRQ. SELECTION
The “HI/LO FRQ.” Selection switch must be set on “LO FRQ.” when switch
contacts are used to generate count input signals. The “LO FRQ.” mode also
provides very high immunity against electrical noise pickup. It is
recommended that this mode also be used, whenever possible, with
electronic sensor outputs. The “LO FRQ.” mode can be used with any type
of sensor output, provided count pulse widths never decrease below 5 msec,
and the count rate does not exceed 100 cps.
3. V
IL
and V
IH
levels given are nominal values ±10% when counter voltage on
“DC OUT” Terminal is +12 VDC. These nominal values vary in proportion
to the variations in “DC OUT” Terminal voltage, caused by line voltage and
load changes.
4. When shielded cable is used, the shield should be connected to “COMM.” at
the counter and left unconnected at sensor end.
NOTES:
INSTALLATION ENVIRONMENT
The unit should be installed in a location that does not exceed the
maximum operating temperature and provides good air circulation. Placing
the unit near devices that generate excessive heat should be avoided.
Continuous exposure to direct sunlight may accelerate the aging process of
the bezel. The bezel should be cleaned only with a soft cloth and neutral soap
product. Do NOT use solvents.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate
the keypad of the unit.
INSTALLATION
The Lynx Counters meet NEMA 4X/IP65 requirements for indoor use,
when properly installed. These units are intended to be mounted into an
enclosed panel with a gasket to provide a water-tight seal. One mounting clip
and two screws with tinnerman nuts are provided for easy installation.
Consideration should be given to the thickness of the panel. Too thin of a
panel may distort and not provide a water-tight seal. (Recommended
minimum panel thickness is 0.125" [3.18 mm].)
After the panel cut-out has been completed and deburred, carefully slide
the panel gasket over the rear of the counter body to the back of the bezel.
Insert the unit into the panel. As depicted in the drawing, install the two
tinnerman nuts and two self-tapping screws onto the mounting clip. To install
the mounting clip; hold the mounting clip with both hands so that the top
corners rest on the index finger of each hand and the bottom corners rest on
the middle finger of each hand. While doing this, place the thumb of each
hand over the mounting screws. By pressing on the screws, flex the clip
enough to slide it over the back end of the Lynx case until the clip snaps into
the groove of the bezel. Tighten the two mounting screws.
Caution: Only minimum pressure is required to seal the panel. Do NOT
overtighten mounting screws.
NOTE: IF EXTERNAL SUPPLY IS USED TO POWER

OR GREATER THAN DC OUT VOLTAGE.
