| Output mode | F mode (Operation continues even when setting is reached.) | |
| Reset system | External, manual resets | |
| Timer operation | Yes | |
| Input method | Voltage inputs: High and low signal voltages (count, reset, short, counter No. selection, I/O inhibit) | |
| Control output | No-contact outputs: RUN, forecast, machine stoppage | No-contact outputs: RUN, forecast |
| Display | Count, preset value, counter number, and error codes displayed on 7-segment LCD Mode, reset, I/O inhibit, re-monitor modes, and key protection displayed on LCD characters Output indication on LCD characters and LEDs | |
| LCD with backlight | Yes | |
| Built-in counter number | 9 (counters 1 to 9) (See note 1.) | |
| Preset stage | 3-stage (See note 2.) | 1-stage (See note 3.) |
| Digits | Forecast value: 6 digits (999999) Pre-forecast value: - 5 digits (See note 4.) Machine stoppage: +5 digits (See note 5.) | Forecast value: 6 digits (999999) |
| Time ranges | Forecast value: 99999.9 h (0.1 h or longer)/99999.9 s (0.1 s or longer) Pre-forecast value: -9999.9 h/-9999.9 s (See note 4.) Machine stoppage: +9999.9 h/+9999.9 s (See note 5.) | Forecast value: 99999.9 h (0.1 h or longer)/99999.9 s (0.1 s or longer) |
| Memory backup | EEPROM (Data can be written 100,000 times.), Backup time for power interruption: Approx. 10 years | |
Note:
1.Each channel operates on a separate I/O.
2.The 3-stage are pre-forecast, forecast, and machine stoppage.
Pre-forecast: Displayed only on LCD (no external output is provided).
Forecast: Displayed on LCD and LED and output (output for each counter).
Machine stoppage: Displayed on LCD and LED and output (output when the count value of one or more of counters 1 to 9 has reached its machine stoppage value).
3.This Counter operates on the forecast value only.
4.The pre-forecast value is set as a negative offset in respect to the forecast value.
5.The machine stoppage value is set as a positive offset in respect to the forecast value.
