1 Single/Dual Preset for and Electronic KCN-S/W KCN-A KCV Maximum counting speed: cps, 1kcps, kcps or kcps (selected by digit keys) With the DIN standard size of only 8 mm by 8 mm, the full featured counter incorporates an easy to read LCD display. Integrating the latest technologies, the counter can be used for many purposes as measuring quantities, length and time. Other options include single preset for general purpose models, and dual preset setting for multifunction counters. Merits Small body and easy to see display With its body of only 8 mm by 8 mm, the counter provides full screen display of either four-digit or six-digit numbers with the height of 1 mm or 1 mm. Easy operation Countup values can be set or modified independently from initial settings. Changes can be made easily and quickly on site. Count display 1mm 1mm The currently selected digit flashes. Preset value Stores a preset value. Backlit LCD integrated in al models Displayed values are backlit to facilitate reading in darkness. Keypad protection cover A keypad cover is attached to prevent erroneous operation. DC power as thin as mm With minimum space requirement, the control board can be installed anywhere. mm AC power is 9 mm thick Increments the value of a selected digit by one. Select a digit to be preset. Switches between first preset mode or second preset mode. A series of models to meet all your needs All 1 models include advanced functions such as prescaling and decimal display. These models can be combined appropriate to satisfy your requirements. Multifunction A complete series of models provide advanced functions such as dual preset nine output modes, count disable, large capacity sensor power (DC V, ma) and AC 1 to V user-selectable power source. Timer option The KCN-S general purpose -digit counter can be used also as a precise digital timer.,subtraction or both operations are available. Twelve error codes quickly report error status. EEPROM to avoid cell replacement The counter uses an EEPROM to eliminate the use of cells. The memory can store all counts, preset values and mode settings. 1mm Water proofed front panel The keypad on the front panel is completely coated (IP) to insulate dust and water. B-

2 Mode options, subtraction and concurrent mode and mode mode In the mode, the count increments by one for each pulse input. When the value has reached a preset value, the counter generates a signal. mode In the mode, the count decrements by one for each pulse input. When the value has reached zero, the counter generates a signal. Count Count Preset value Pulse input Preset value Pulse input Sensor Sensor RST RST Incremented to 99 Decremented to 1 KCN-S/W KCN-A KCN-A Electronic and Counting operation is not affected by any deviation of roller movement. Roller for length measurement pulse and subtraction pulse can be entered separately or simultaneously. Subtration Deviation RST Rotary encoder Two-phase signal RST Prescaling Converting the number of pulses to quantity or dimension Quantity Sensor RST Multiplied by Prescaled at Four workpieces per pulse Roller for length measurement Cutter Cut length (in mm) Can be set to a rounded integer. You need not consider the roller's diameter when setting the counter value Setting in inches Rotary encoder.8 mm per pulse Either unit is selectable with the prescaling function Setting in meters Change in the mechanism are not required RST Prescaled at.8 B-

3 Electronic Displaying a decimal point A decimal point can be displayed at a desired location. KCN-S/W KCN-A KCV Switching the input logic between positive and negative Device choices are expanded by two input logics available for positive (voltage) input and negative (no voltage) input. Relay RST Decimal point Proximity switch Photoelectric sensor Relay output KCN- R DC output KCN- T Rotary encoder Nine operation modes The multifunction counter has nine operation modes, including Compare, Hold, Auto and One shot Output. Ex. Count of the number of workpieces (Compare mode) Photoelectic sensor at entry Photoelectic sensor at exit Subtration RST (Mode ) C P1 Conveyor The counter counts and displays the number of workpieces on the conveyor. The count is added to by input pulse generated by the photoelectric sensor at the entry, and subtracted from by pulse generated by another sensor at the exit. and subtraction can occur at the same time.

SET SET1 Mode Mode Mode 9 are available only on dual preset mode. Single preset mode operate as described under SET,. In One Shot mode, output duration ranges from 1 to 999 ms. One Shot output turns off when reset signal is entered. In One Shot mode, another countup causes signal output for a set duration. In Mode Mode, counting at k cps is interrupted for. to. ms between countup and next pulse input. In both modes, counting at k cps is not affected by countup. Signal output is controlled as follows regardless of the magnitudes and the signs of SET1 and SET: In Hold mode, it generates and hold signal when the count equals preset value. In One Shot mode, it generates signal momentarily when the count equals preset value. In Compare mode, it generates signal when the count is equal to or larger (or smaller) than the preset value.

For any other errors, press the key to clear the error code then make the current settings. Possible cause Count has exceeded upper limit. Count has decreased below lower limit. Preset value divided by prescale exceeds count range. The error code is followed by 1 or to indicate SET1 or SET error. A memory data error occurs when the current settings do not produce a meaningful result. Notes: The counter continues counting even after an overflow or underflow has occurred. This is performed in the range of to 18.. The counter is self-checked for errors when its power is turned on. When an error occurs, counting and display are disabled except for overflow and underflow.

The KCN-W counters integrate a switching source circuit. ing the counter causes a surge current to flow into the circuit and may prevent counter operation. Use a power source with a sufficient capacity to prevent the surge current. Keep the source voltage in the to V range for DC -wire proximity switch. After changing initial settings, always press the RST key to reset the counter. To use the counter as timer, connect the common input (sensor power) terminal to the Counter-Timer switch terminal then turn the power on. After you change the timer range from " S" to " M:S" or " H:M", check that the second digit of the preset value is set to a number less than. If necessary, correct the value to prevent a preset error. When you switch the function from timer to counter, re-enter the initial settings and preset value. Any changed preset value during counting is enabled by pressing the key. For maintenance purposes, keep records of the initial settings and preset values. During counting, any change to a preset value become. Avoid using the counter in the environments where: (1)Ambient temperature is above or below 1. ()Ambient humidity exceeds 8, or abrupt temperature changes may cause dewing. ()The operation may be affected by dust, metal chips, corrosive gases or other harmful objects. ()The machine is exposed to direct sunlight. ()You anticipate vibration or shock. Keep the following in mind when wiring: (1)The wiring to the counter should be separated from power line.
