User manual OMRON H7BX DATASHEET

[. . . ] Multifunction Counter H7BX DIN 72×72 mm Multifunction Counter with a Bright, Easy-to-view, Negative Transmissive LCD. · Highly visible display with backlit transmissive LCD. · Selectable display color (red/green) enables checking output status at a distance. · Provides a total and preset counter, batch counter, dual counter, and tachometer (See note. ). · Wide range of inputs accepted for NPN/PNP inputs (multi-inputs) and 2wire DC sensors. [. . . ] If there is power failure while an 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 0 and 999999. Multifunction Counter H7BX 15 Self-holding Instanta- One-shot output output neous (equals) output (The one-shot output time can be set in the range 0. 01 to 99. 99s. ) Input mode UP/DOWN A, B, C Operation after count completion Reset/reset 1 999999 Set value 2 Set value 1 K-2 0 -99999 The display continues to increase/ decrease until the overflow or underflow value is reached. Only a one-shot output is possible. OUT1 OUT2 Reset/reset 1 999999 Set value 2 Set value 1 D 0 -99999 The display continues to increase/ decrease until the overflow or underflow value is reached. 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 is held while the present value is less than or equal to set value 1. OUT2 is held while the present value is greater than or equal to set value 2. 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. 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 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. [. . . ] 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. 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. [. . . ]
