The Model LNXC1 is the manual or on equipment must be observed to ensure personal safety and to single preset version and the Model LNXC2 is the dual preset version. Both prevent damage to either the instrument or equipment connected to it. If units have a solid-state output and a Form C relay output for each preset. These equipment is used in a manner not specified by the manufacturer, the protection units feature selectable input configurations, a full compliment of control provided by the equipment may be impaired. inputs, programmable timed outputs, prescale capability with disable switch Do not use this unit to directly command motors, valves, or other actuators (dual preset only), non-volatile memory, and many other features which will not equipped with safeguards. To do so, can be potentially harmful to persons satisfy most any single or dual preset application. or equipment in the event of a fault to the unit. The Lynx Counters have two main counting actions, Reset to Zero (RTZ) and Reset to Preset (RTP). There are eight modes of operation for the single preset SPECIFICATIONS unit and sixteen for the dual preset unit. 1. DISPLAY: 6-digit, 0.3" (7.6 mm) high LCD display.

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.

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 Caution: Only minimum pressure is required to seal the panel. Do NOT the groove of the bezel. Tighten the two mounting screws. overtighten mounting screws. 7 CALCULATING THE PRESCALER (Dual Preset Only) The LYNX is factory set to provide 1 count on the display for each pulse that WHERE: is input to the unit. In many applications, there will not be a one to one DISPLAY UNITS - The number of units (revolutions, feet, 10ths of feet, correspondence between input pulses and display units. In these applications it meters, etc.) that would be acquired after the “Number of Pulses” has will be necessary for the LYNX to scale or multiply the input pulses by a occurred. prescaler to achieve the proper display units (feet, meters, gallons, widgets, NUMBER OF PULSES - The number of pulses required to achieve the etc.). number of “Display Units”. The “Prescale”, denoted as “K”, is simply the total amount of scaling required. It is obtained by dividing the “Display Units” by the “Number of Pulses” as shown in the Formula below. K = Display Units/Number of Pulses APPLICATION FOR DUAL LEVEL PRESET LYNX COUNTER CARPET ROLL MEASURING & CUTTING OPERATION This application requires the control of a motor which winds carpet onto a After programming is complete, activating the key switch connects roll. An early warning signal is required to slow the motor 10 yards before it Program Disable, “PGM.DIS.” to “COMM.” and prevents accidental changes is to be stopped. The roll length setting should be protected against to programmed values. “REMOTE RESET” is accomplished by connecting unauthorized changes and the system must be restarted from a remote location. the contacts of a pushbutton switch to the “REM.RST.” and “COMM.” A dual preset LYNX counter is used to satisfy all of the above requirements. terminals of the LYNX. The measurement of the carpet is done by using a double wheeled version of the LSC sensor. The LSCDY20F was chosen for its 10 pulses per yard output and its durable polyurethane wheels. As the carpet is wound onto the roll, the LYNX starts counting down from its preset value of 300 yards. With a prescale value of 0.10000, the counter decrements once for every 10 pulses and indicates the number of whole yards remaining. Relay 1 turns on when the counter reaches 10, signaling the motor controller to start the slowdown process. Relay 2 turns on when the counter reaches “0”, stopping the motor completely. The operator manually cuts the carpet and removes the full roll, replacing it with an empty one. The “REMOTE RESET” button and the “MOTOR START” button are pushed to start the sequence over again. Any roll length can be programmed into Preset 2 without changing Preset 1. Preset 1 will always turn on 10 yards from the end of the roll.
