Total count value • The counting range of the total counter is −99,999 to 999,999. The total count value 0 returns to 0 when it reaches the full scale limit. Batch Counter Operation The H7BX has a batch counter separate from the 1-stage preset counter for counting the number of times the count has been completed. Reset 1 Reset 2 (batch • The batch counter continues after count counter reset) completion. Set value • Batch output is held until batch counter reset Present value input turns ON. 0 • When the batch counter reset input is turned ON, the batch count value is reset, and OUT2 batch output turns OFF. Batch count set value • If the Reset Key is pressed while the batch (Sub-display) count value is displayed, the batch count 2 Batch count value 1 value is reset and batch output turns OFF. (Main display) 0 The present value is also reset at this time. OUT1 (batch output) Note: The above is for when the output mode is C. Note: 1. The batch count value is held at 0 while the batch counter reset input is on. 2. If the batch count set value is 0, batch count will be performed but there will be no batch output. 3. The batch count value returns to 0 when it reaches 999,999. 4. Once batch input has been turned ON, it will return to the ON state after power interruptions. 5. If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON. 6. After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch count value. Dual Counter Operation Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for which output turns ON when the set value matches the added or subtracted result. (1) Dual Count Calculating Mode = ADD (2) Dual Count Calculating Mode = SUB Dual count value = CP1 PV + CP2 PV Dual count value = CP1 PV - CP2 PV Reset 1 Reset 1 (CP1 reset) (CP1 reset) • The operation after count completion for the dual counter value is determined by the Reset 2 Reset 2 (CP2 reset) (CP2 reset) output mode. Dual count set value • The CP1 present value is reset when reset Dual count set value 1 input is turned ON and the CP2 present Dual count value Dual count value 0 value is reset when reset 2 input is turned ON. 0 CP1 present value • If the Reset Key is pressed while the dual CP1 present value count value, CP1 present value, or CP2 0 present value is displayed, all of the present 0 CP2 present value CP2 present value values are reset and the outputs turn OFF. 0 0 At this time, counting is not possible for CP1 or CP2 inputs. OUT1, 2 OUT1, 2 Note: The above is for when the output mode is N. Note: The above is for when the output mode is K-2. SUB mode can be used only when K-2, D, L, or H is selected as the output mode with 6-digit models. Note: 1. Counting is not possible for CP1 while the reset 1 input is ON. CP2 is not affected. The dual count value will be calculated based on a CP1 present value of 0. 2. Counting is not possible for CP2 while the reset 2 input is ON. CP1 is not affected. The dual count value will be calculated based on a CP2 present value of 0. 3. The counting range for the dual count value is −99,999 to 999,999. The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999. If a present value exceeds 999,999, FFFFFF will be displayed to indicate an overflow, and all counting will stop. 17 H7BX Reset Function List 1-stage/2-stage Function Total and preset counter Batch counter Dual counter counter Batch count Dual count CP1 present Display in run Present value/ Present value/ Total count Present value/ value/batch value/dual value/CP2 mode set value (1, 2) set value value set value count set count set present value value value Present value Reset/reset 1 Present value and output reset.

Do not use it in locations subject to destroy output elements, possibly resulting in short-circuit or oil. • Install the H7BX well away from any sources of excessive static open-circuit faults. • Install a switch or circuit breaker that allows the operator to electricity, such as pipes transporting molding materials, power, or immediately turn OFF the power, and label it to clearly indicate its liquids. • Store the H7BX within the specified ratings.

Periodically inspect and replace parts. • Maintain voltage fluctuations in the power supply within the specified range. • Internal elements may be destroyed if a voltage beyond the rated voltage is applied. • When the power is turned ON, an inrush current will flow for a short time (approx. 10 A for 2 ms). Depending on the power supply capacity, operation may not start. Be sure to use a power supply with a sufficient capacity. 25 H7BX Precautions for Correct Use • Inrush current generated by turning ON or OFF the power supply may deteriorate contacts in the power supply circuit. Turn ON or OFF using a device with a rated current of 10 A or higher. • Input signals may be accepted, not accepted, or unstable for the following time when the power supply is turned ON or OFF. Set the system to allow leeway in the timing of input signals. ON Power supply OFF 200 ms 0 to 90 ms 5 ms 0 to 1 s Un- Impossible Input Impossible Possible Unstable stable • This H7BX always compares the count value with the set value. Thus, if you change the set value during operation, please remember that the output will turn ON when the set value becomes equal to the count value. • With the factory setting, the output will turn ON when power is supplied to the H7BX because the set value and count value are both zero. While resetting, however, the output stays OFF. • EEPROM is used as memory when the power is interrupted. The write life of the EEPROM is 100,000 writes. The EEPROM is written when settings are changed, or the power is tuned OFF. • Water resistance will be lost if the front sheet is peeled off or torn. Do not use the H7BX if the front sheet is missing or torn. • Abide by all local ordinances and regulations when disposing of the H7BX. • External Power Supply Reduce the load current as shown in the diagram on the right according to the power supply voltage if a DC power supply is used for models specified for 24 VAC/12 to 24 VDC. 100 20 15 0 10.8 Power supply voltage (VDC) 26 Load current (mA) Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
