GC2 | GH2/GM2/GS2
Q
Is it possible to use GC2 series as a drop-in replacement of GC series?
A
Yes, but if you are using a switch [or a contact] for sending input signals, there is a possibility that the switch will not work normally. This is because of sink current from the GC2 series to the switch: sink current from GC2 series is very small.
In case the switch does not work with GC2 series normally, it is necessary to consider using a switch [or a contact] that is capable of handling micro electric current, or modifying the circuit diagram as shown below so that the sink current from the GC2 series to the switch will increase.
Please choose a resistance value R that will let approximately 1 mA current flow through it with external power-supply voltage applied between 2 VDC to 30 VDC.
GC2 | GH2/GM2/GS2
Q
The electronic counter displays a value that is larger than the correct value. What is the possible cause?
A
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).

Q
The electronic counter erroneously makes counts. What is the possible cause?
A
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 μF) 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.

Q
Is it possible to connect a voltage-output sensor to an electronic counter that accepts open-collector input?
A
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.

Q
What is open-collector output?
A
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.

Q
Even though I tried resetting the electronic preset counter, the value is not reset to "0". What is the possible cause?
Q
What is BCD input?
A
BCD stands for Binary-Coded Decimal, in which decimal numbers are expressed in combination of 4 binary digits: for example, the 4 binary digits of “0110” equals to the decimal of “6”.
BCD input is an input method that is used when G90-303/G95-303 receives an external input of numerical value.

Q
What is the setting of Prewarn?
A
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 Hold output?
Q
What does "Display is frozen during output although counting is available." mean?
A
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.
E60 | E48 | G48-N
Q
What does "Does not count during output." mean?
A
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.
E60 | E48 | G48-N
Q
What is 90°quadrature input?
A
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/Pulleys rotate in forward direction and count down when they rotate in reverse direction.
E21 | E10 | E60 | G90 | G95 | E48 | G48-N
Q
How is a DC 2-wire sensor wired directly to an electronic counter?
A
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.

Length Measuring Counter / Sensor
Q
Errors in length measurement have become larger as the measurement continued.
Q
Soon after the installation of the length counter/sensor, large errors in measurement have been observed. Is this a defective product?
Q
What kind of phenomenon is it that the Wheels/Pulleys are slipping?
A
It is a phenomenon that the Wheels/Pulleys are not rotating normally but are suffering some slips over the object of measurement.
The force of friction between the Wheels/Pulleys and the object of measurement prevents the Wheels/Pulleys from sliding easily over the surface of the object. Therefore, the Wheels/Pulleys slip when this force of friction gets lower, and the real length of object will be larger than the measured length.
RY1 | RY | MWC | Wheels/Pulleys | CR | CT1 | CS
Q
What is the factor that decides the accuracy of measurement by length counters?
