Precautions Power Supply The capacity of the external power supply is ma at 1 VDC/8 ma at 4 VDC switchable. When using a 4 VAC/1 to 4 VDC power supply type, reduce the load with the power supply voltage, as shown in the following diagram (When supplying external power). oad current (ma) 8 1 1 5 Supply voltage (VDC) 1 VDC 4 VDC Power Supplies When turning the power ON and OFF, signal reception is possible, unstable, or impossible as shown in the diagram below. The unstable period will vary with power supply voltage, and the load conditions on external power supplies. Power supply ON OFF to 5 ms 1 ms to 1. s Input impossible Possible impossible Unstable A switching regulator is used in the internal circuits of counters with 1-to-4-VAC or 1-to-4-VAC specifications, causing an inrush current (approx. 1.5 A) to flow when power is turned on. If the capacity of the power supply to the counter is insufficient, the counter may not start operation. Be sure to provide adequate capacity (recommended supply capacity; 5 W min.) Connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value immediately. DIP Switch Setting Changes Any changes in the DIP switch settings while power is being supplied is invalid. Restart the power supply. Self-diagnostic Function The following displays will appear if an error occurs. The present value and output enter the same status as after pressing the RESET Key. Display Error Output status * ** Present value below min. Present value above max. No change Correction Press RESET Key or reset Function setting No change CPU OFF Press RESET Key Memory Set at the factory *Displayed when the present value has fallen below the min. value in the -C (±range type). **Displayed when the present value has exceeded the max. value in the -C (±range type). Operating Environment When using the Counter in an area with much electronic noise, separate the Timer, wiring, and the equipment which generates the signals as far as possible from the noise sources. It is also recommended to shield the signal wiring to prevent electronic interference. Organic solvents (such as paint thinner), as well as very acidic or basic solutions might damage the outer casing of the Counter. Using the Prescale Function When setting the prescale value, be sure that the set value satisfies this equation: set value max. value - prescale value. (if the prescale value is 1,5, 999.999-1,5 = 998.749 max.) If a higher value is used, the output may be affected, so make sure that the output is produced before starting operation. Changing Set Values When changing the set value while the Counter is operating, the output will be produced if the set value ever equals the present value. To avoid triggering the output, begin by incrementing a higher digit to a large number. ting with a Set Value of When resetting is performed with the set value set to, no output will be given for the safety reasons once the reset is turned OFF (except for the -C). 3
Output Delay The following table shows the delay from when the present value passes the set value until the output is produced. (The delay is the result of output control time, signal transmission time, relay switching time, etc.) Actual measurements in N and K modes. Control output Max. counting speed Output delay* Contact output 1, 3 z {cps} to 4 ms 1 kz {cps} 4.7 to 5.8 ms 5 kz {cps} 4.4 to 5.4 ms 1 kz {cps} 4.3 to 5.3 ms Transistor output 1, 3 z {cps} 13.5 to ms 1 kz {cps}.59 to.81 ms 5 kz {cps}.9 to.44ms 1 kz {cps}.4 to.36ms Batch outputs 3 z {cps} 13.6 to. ms 1 kz {cps}.7 to.94 ms 5 kz {cps}.4 to.57ms 1 kz {cps}.37 to.49ms *The variation in delays is due to different modes and conditions. For systems where the delay is a problem, take actual measurements under operating conditions. Max. Count Speed of Batch Counter The maximum count speed of the batch counter is 1 kz (cps). The batch counter counts the number of count-up times at the last stage (i.e., the number of preset-value counts if the is a one-stage model and the number of SET preset-value counts if the is a two-stage model). An interval of 1 ms or more is required before the batch counter counts up again after it has counted up. Response Delay Time for ting (Transistor Output) Take the following output delays into consideration after the reset signal is turned ON and the output is turned OFF. Minimum reset signal width Output delay time 1 ms.8 to 1. ms ms to 5 ms Other When the Counter is installed in a control box and tests are conducted which may damage the Counter s internal circuitry (for example, a test measuring the maximum voltage difference between the control circuit and metal components), remove the Counter from the control box or short-circuit the terminals.
