CALCULATING THE PRESCALER (Dual Preset Only)
The LYNX is factory set to provide 1 count on the display for each pulse that
is input to the unit. In many applications, there will not be a one to one
correspondence between input pulses and display units. In these applications it
will be necessary for the LYNX to scale or multiply the input pulses by a
prescaler to achieve the proper display units (feet, meters, gallons, widgets,
etc.).
WHERE:
DISPLAY UNITS - The number of units (revolutions, feet, 10ths of feet,
meters, etc.) that would be acquired after the “Number of Pulses” has
occurred.
NUMBER OF PULSES - The number of pulses required to achieve the
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
roll. An early warning signal is required to slow the motor 10 yards before it
is to be stopped. The roll length setting should be protected against
unauthorized changes and the system must be restarted from a remote location.
A dual preset LYNX counter is used to satisfy all of the above requirements.
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.
The following is a list of the DIP switch settings and terminal connections
to meet the process requirements.
After programming is complete, activating the key switch connects
Program Disable, “PGM.DIS.” to “COMM.” and prevents accidental changes
to programmed values. “REMOTE RESET” is accomplished by connecting
the contacts of a pushbutton switch to the “REM.RST.” and “COMM.”
