Precautions for Correct Use

1.  Read this manual carefully before using the product.

2. An inrush current of approx. 10 A will flow for a short time when the power supply is turned ON. If the capacity of the power supply is not sufficient, the Counter may not start. Be sure to use a power supply with sufficient capacity.

3.  Make sure the power supply voltage and loads are within the specifications and ratings for the product.

4.  To allow for the startup time of peripheral devices (e.g., sensors), start Counter timing operation 200 ms to 290 ms after turning ON the power. The input signal will not be accepted before 200 to 290 ms has elapsed.

5.  The input signal will not be accepted after 5 to 1005 ms has elapsed from when the power supply is turned OFF.

6.  Inrush current generated by turning ON or OFF the power supply may deteriorate contacts on the power supply circuit. Turn ON or OFF to a device with the rated current of more than 10 A.

7.  The capacity of the external power supply is 100 mA at 12 V. When using a 24 VAC/12 to 48 VDC power supply, reduce the load with the power supply voltage, as shown in the diagram (DC power supplies only) on the right.

8.  If the prescale value setting is incorrect, a counting error will occur. Check that the settings are correct before using this function.

9.  Make sure that all settings are appropriate for the application. Unexpected operation resulting in property damage or accidents may occur if the settings are not appropriate.

10.  Do not leave the Counter for long periods at a high temperature with output current in the ON state. Doing so may result in the premature deterioration of internal components (e.g., electrolytic capacitors). Do not install the product close contact with the heating element.

11.  Non-volatile memory is used as backup memory when the power is interrupted. The write life of the non-volatile memory is 100,000 writes. The non-volatile memory is written when the power is turned OFF or when switching from function setting mode or configuration selection mode to run mode.

12.  Dispose of the product according to local ordinances as they apply.

13.  Attach the front panel when using the Counter. The latches in the middle of each of four sides secure the front panel to the main body. To remove the panel, widen the four latches and pull the panel toward you. To mount the panel, fit all four latches correctly into the slots on the main body.

14.  Do not use because it may be damaged inside the product when the product fall by mistake.
    Confirm the wiring the input and output terminals correctly before power is supplied.

15.  Do not use the product near radio wave receivers. Doing so may cause incoming radio wave interference.

16.  Do not use in a circuit with the waveform is distorted. The error will increase due to the influence of the distorted waveform.

17.  Install product so that the load doesn’t span the product body.

Mounting

Front panel dimensions are the same for all models.

Diagnostic

1. This includes times when the life of the non-volatile memory has expired.
2. This occurs if the present value or total count value falls below –99999.
3. This occurs in the following conditions if the present value (i.e., measurement value) exceeds 999999.
4.  For Output Modes K-2, D, L, or H
5.  Dual counter or tachometer operation is used.
6.  Display flashes. (1-second cycles)
7.  This does not apply when tachometer operation is used.
8.  This is displayed if the alarm set value for either of the two outputs is exceeded if a model with two outputs is used. The total ON count will not be cleared by using the Reset operation.
9.  The normal display and Rplc will appear alternately. When the Reset operation is performed, Rplc will no longer be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the Counter will continue without clearing the total run time and the output ON count.)If the power supply is turned OFF/ON after the Rplc display is turned OFF by Reset operation, Rplc will be displayed again. In order to prevent the display even after the power supply is turned OFF/ON, change the alarm set value to equal to or greater than the count value, or change the alarm set value to 0 to be invalid.
