The outputs are ON while the count is equal. OUT1 OUT2 Output mode setting Reset/reset 1 999999 Set value 2 Set value 1 L 0 -99999 The display continues to increase/ decrease until the overflow or underflow value is reached.

OUT1 OUT2 Reset/reset 1 999999 Set value 2 Set value 1 H 0 -99999 OUT1 The display continues to increase/ decrease until the overflow or underflow value is reached. OUT1 is held while the present value is greater than or equal to set value 1. OUT2 is held while the present value is greater than or equal to set value 2. Note: H mode is available only when using a 2- stage counter. OUT2 Note 1. Counting cannot be performed while the reset/reset 1 input is ON. If reset/reset 1 input turns ON while the one-shot output is ON, the one-shot output turns OFF. If there is power failure while the output is ON, the output will turn ON again when the power supply has recovered. For a one-shot output, the output will turn ON again for the duration of the output time setting once the power supply has recovered. Do not use the counter function in applications where the count may be completed (again) while the one-shot output is ON. The set values are between -99999 and 999999. 16 Multifunction Counter H7BX Total and Preset Counter Operation The H7BX has a total counter separate from the 1-stage preset counter for counting the total accumulated value. Reset/reset 1 Total reset/reset 2 Present value 0 999999 Total count value 0 · The total counter continues to count the total accumulated value when the present value is reset using reset/reset 1 input (Reset Key). · The total count value is reset when the total reset/ reset 2 input is turned ON. If the Reset Key is pressed while the total count value is displayed, the total count value is reset. The present value is also reset at this time. · The counting range of the total counter is -99, 999 to 999, 999. The total count value 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 counter reset) Set value Present value 0 OUT2 Batch count set value (Sub-display) Batch count value (Main display) 0 2 1 · The batch counter continues after count completion. · Batch output is held until batch counter reset input turns ON. · When the batch counter reset input is turned ON, the batch count value is reset, and batch output turns OFF. · If the Reset Key is pressed while the batch count value is displayed, the batch count value is reset and batch output turns OFF. 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.
