Precautions
!WARNING
touch terminals while power being supplied. Doing result electric shock.
Correct
Long-term
products within specified ranges. When using inside control panel, ensure that temperature around product, rather than temperature around control panel, does exceed specified temperature range. Electronic products, such this product, have lifetime that dependent lifetime internal electronic components, opposed lifetime related number relay switching operations. lifetime these components varies with temperature; higher temperature, shorter lifetime. Therefore, product lifetime extended lowering internal temperature product. When several Frequency/Rate Meters mounted close together (either horizontally vertically), internal temperature Frequency/Rate Meters rise, leading reduction lifetime. this case, take measures cool Frequency/Rate Meters, such installing fans. Ensure, however, that terminals cooled this lead incorrect measurement.
!Caution
allow metal objects conductive wire cuttings enter product. Doing result electric shock, fire, malfunction.
!Caution
attempt take product apart touch internal parts while power being supplied. Doing result electric shock.
!Caution
product locations subject flammable explosive gases. Doing result explosion.
!Caution
lifetime output relays varies greatly with switching capacity conditions. Consider actual operating conditions, relays within rated load without exceeding number operations specified rated electrical life. Using relays beyond their rated electrical life result contact deposit burning.
Operating Environment
product locations subject temperatures humidity levels above specified ranges, locations subject condensation. product locations subject severe shocks vibrations. Separate product from machines that generate high-frequency noise, such high-frequency welding machines high-frequency sewing machines. product locations subject dust corrosive gases. product outdoors locations subject direct sunlight.
!Caution
loads exceeding rated value. Doing result damage burning.
!Caution
power supply voltage within specified range. doing result damage burning.
!Caution
settings that appropriate control system. Discrepancies between settings actual control conditions result unexpected operation leading damage accidents.
Operation
When using models with comparative outputs, error occurs Frequency/Rate Meter, comparative output operate correctly. therefore recommend that consider providing alarm system separately countermeasure. Parameter settings that allow functions operate properly made, using setting menu, factory prior delivery. When using product, change settings required application.
!Caution
sure tighten terminal screws specified torque. Specified torque M3.5 screws: 0.74 0.90 Loose screws result burning malfunction.
Application Precautions
power supply voltage within specified range. doing result damage burning. sure perform wiring correctly, verifying terminal names. Incorrect wiring result burning. sure tighten screws terminal block properly. connect anything unused terminals.

Operating Modes
K3NR provides operating modes converting input pulses display values. mode selected operations front panel. Basically, operating modes divided into following groups.
Operating Modes
Rotational speed other displays based calculations continuous pulses (frequency).
Operating Mode
number pulses measured. Each pulse counted count maximum 99,999 counts. Decrementing count possible. Although limits display enables displaying only 99,999 counts, prescaling used count gigacounts. Operating mode Pulse counting

Mode Display calculations rotational speeds Mode
Basic Principles Rotational Speed Displays ON/OFF time sensor input other input measured with internal system clock automatically calculate frequency. This frequency multiplied displayed rotational speed.
Input sensor pulse ON/OFF time Frequency
Rotational speed (rpm) Circumferential speed Circumference Rotational speed Passing time Processing length/Circumferential speed Automatic measuring K3NR enabled simply providing input pulse.
Operating Mode Rotational/Circumferential Speed
frequency input calculated displayed rotational circumferential speed. Units: rpm; rps; rph; kHz; mm/s; m/s; m/min; km/h; l/min; l/h; etc.
