Vibration Comparator Frequently Asked Questions
Question number FAQ-1395
Comparable output and terminal block (reset, gate input)
For information on the comparison function, please refer to "Measurement Modes and Comparison Function," and for setting instructions, please refer to the "Quick Operation Manual."
To connect to external devices such as a sequencer and control the judgment timing, use AUTO mode. This is controlled using reset and gate signals. Please refer to the instruction manual for details.
■ Reset signal, gate signal input
| Input signal | Rear terminal block No. | specification | Operation during AUTO mode |
|---|---|---|---|
| Reset | No. 7 Reset signal No. 9 COM | The device resets when the terminals are short-circuited or when a low-level signal is input. In the case of voltage signal input LOW: 0.8V or less | (1) Enter the reset command with the gate OFF (comparison stop). (2) Gate ON (Comparison begins) (3) Read the judgment output with the gate OFF. (4) Return to (1) and proceed to the next measurement. |
| gate | No. 8 Gate Signal No. 9 COM |

■ Comparator output (NG signal)
The A BAND, B BAND, and C BAND (optional) each output a NG (Not Good) judgment signal.
| band | Rear output terminal block No. | |
|---|---|---|
| A BAND NG output | No.20 NG Negative Logic Output No. 21 NG Positive Logic Output No.22 Same as above COM terminal | Open collector DC 35 V max, 25 mA max (See the diagram below for the circuit diagram) |
| B BAND NG output | No.23 NG Negative Logic Output No.24 NG Positive Logic Output No.25 Same as above COM terminal | |
| C BAND NG output (option) | No. 26 NG Negative Logic Output No.27 NG Positive Logic Output No.28 Same as above COM terminal |
