E60 Series

* When set to 0, counter will count down from displayed value to 0, when output signal occurs.

• Product Counting

  Counters can be used for counting, sorting and packaging various products.

• Cut-to-length operation

  Counters and CT1/CS pulse generator can be used for cut-to-length operation for textile, paper, plastic film and so on.

  

• Length Measuring

  Counters and rotary encoders can be used for measuring the length of textile, paper, plastic film and so on.

  

• Is it possible for an electronic counter to count pulses while receiving a reset signal?
• No, the existing models cannot count pulses while receiving a reset signal.


• The electronic counter displays a value that is larger than the correct value. What is the possible cause?
• Please check whether "Count Speed" of the counter is set properly.
  If you are using a dry contact like a switch or relay at a high Count Speed setting (ex. 1 kHz) , there is a possibility that the electronic counter is affected by chattering. In this case, please select lower Count Speed setting (ex. 30 Hz).


• The electronic counter erroneously makes counts. What is the possible cause?
• Please consider changing the layout of cables and/or relocating the electronic counter. There is a possibility that the electronic counter is affected by external noises.
  In some cases, the situation improves by installing a capacitor (0.01 to 0.1 ��F) between an input terminal and a GND terminal of the counter. Appropriate capacitance depends on Count Speed, operating environment, etc. Please select a capacitor with an appropriate withstand voltage based on input voltage.


• Is it possible to connect a voltage-output sensor to an electronic counter that accepts open-collector input?
  
• As long as it is NPN output, the voltage-output sensor can work with E10 series, or other electronic counters of which Input Mode is selectable: the user is supposed to select open-collector input. Please note that Input Logic can be reverse in some cases.
  If the sensor makes PNP output, it does not work with our electronic counters.


• Is it possible to connect a TTL-output sensor/encoder to an electronic counter?
  **TTL stands for Transistor-Transistor Logic.
• Unfortunately, our electronic counters do not cater to the voltage input of TTL level (low-level voltage <0.8 VDC, high-level voltage >2.0 VDC)


• Is it possible to connect a line-driver-output sensor/encoder to an electronic counter?
  
• Unfortunately, our electronic counters do not accept line-driver input.


• What is line-driver output?
• It is a kind of output that is based on differential signaling method in which a pair of conductors carry signals of opposite polarity.
  It is an output with a high-noise immunity and capable of a long-distance transmission.
  Some models of our rotary encoder CB series can perform line-driver output.


• What is open-collector output?
• It is an output circuit in which collector of a transistor works as an output terminal. In case the open collector is configured as NPN, external sink current flows into collector (output terminal) when internal transistor is ON. Voltage is not applied to the output terminal, therefore, the terminal can be connected regardless of its counterpart's voltage level.


• In response to an input of one pulse, the electronic preset counter displays different values. What is the possible cause?
  
• Possibly, Prescale function is activated. Please enter PROGRAM MODE and check whether Prescale value is set at "1".


• Even though I tried resetting the electronic preset counter, the value is not reset to "0". What is the possible cause?
• Possibly, Writing function is activated. Please enter PROGRAM MODE and check whether Writing value is set at "0".


• What is the setting of Prewarn?
• An electronic preset counter with this feature makes an output in the following way. - When the counter is on its way to a preset value by adding: Before reaching the preset value, the counter makes an output at the value of "(Preset value) - (Prewarn value)". Ex. Preset value = 10, Prewarn value = 2 The counter makes an output at 8 when it is adding to 10. - When the counter is on its way to a preset value by subtracting: Before reaching the preset value, the counter makes an output at the value of "(Preset value) + (Prewarn value)". Ex. Preset value = 10, Prewarn value = 2 The counter makes an output at 12 when it is subtracting to 10.


• What is Overrun?
• When Overrun is activated, the electronic preset counter won't be reset even after reaching its preset value and will keep on counting.


• What is Auto-reset?
• When Auto-reset is activated, the electronic preset counter will be reset after reaching its preset value.


• What is One-Shot output?
• It is one of two settings concerning how long an output will be made by an electronic preset counter.
  When the counter reaches its preset value, an output signal will be made for a predetermined period of time.


• What is Hold output?
• It is one of two settings concerning how long an output will be made by an electronic preset counter.
  When the counter reaches its preset value, an output signal will be made and held until a preselected condition is satisfied.


• What does "Display is frozen during output although counting is available." mean?
• This is related to how the electronic preset counter treats input pulses while making an output.
  If you select an operation mode that includes the said description, the counter will keep on counting input pulses while an output is made.
  On the other hand, the count value on its display will be fixed to the value that is reached when the output is made. The value on the counter will be updated as soon as the counter stops making the output signal.


• What does "Does not count during output." mean?
• This is related to how the electronic preset counter treats input pulses while making an output.
  If you select an operation mode that includes the said description, the counter will stop counting input pulses while an output is made.
  Therefore, the count value on its display will be fixed to the value that is reached when the output is made.


• What is 90°quadrature input?
• It is a kind of input method in which 90-degree phase difference is made between input A and input B, so that the direction of addition and the one of subtraction can be detected by an electronic counter.
  Some models of CT1 series can perform 90° quadrature output. Receiving input from such a model of CT1 series, an electronic counter can count up when the wheels rotate in forward direction and count down when they rotate in reverse direction.


• How is a DC 2-wire sensor wired directly to an electronic counter?
• The power wire of the sensor should be connected to an input terminal of the electronic counter and the ground wire of the sensor should be connected to a GND terminal of the electronic counter.
  Also, please make sure Input Mode of the counter is "open collector".
  Please kindly note that, in some cases, an electronic counter won't work with your DC 2-wire sensor due to the specifications of the sensor: leakage current; residual voltage.
  It is possible to wire a DC 2-wire sensor directly to the following electronic counters: G48, E48, E21, and E60.
  


• What is the tolerance of the thickness of a mounting panel for an electronic counter (GR2, GC2, GH2, GM2, GS2, G48, E48, E60, E10, E21, MD, MDR)?
  
• The thickness should be between 1 to 5 mm. If the counter comes with a gasket, the thickness should be 1 to 5 mm including the gasket.
