- Input Signals: Connect the PNP or NPN input sensor/signal source to the input terminals. Ensure correct polarity for NPN/PNP types.
- Output Connections: Connect the load devices to the relay outputs (SPDT, SPST) and NPN open collector outputs as required by your application. Observe maximum voltage and current ratings for the outputs.
- Grounding: Ensure the unit is properly grounded to prevent electrical noise and ensure safety.
6. Operating Instructions
The CT6M-2P4 offers various operating modes for counting and timing. Refer to the detailed programming guide in the full product manual for advanced settings.
6.1 Basic Operation Modes
- Counter Mode: The device counts input pulses and activates outputs when a preset value is reached.
- Timer Mode: The device measures time intervals and activates outputs based on preset time values.
6.2 Setting Presets
Use the front panel buttons to navigate through the menu and set the desired preset values for counting or timing. The 6-digit LED display will show the current value and allow for adjustment.
6.3 Prescale Value Setting
The prescale function allows the input pulses to be multiplied or divided by a set value before being displayed or processed. This is useful for converting raw pulse counts into meaningful units (e.g., liters, meters).
6.4 Batch Function
The batch function enables counting or timing of multiple cycles or batches, providing an additional layer of control for repetitive processes.
7. Maintenance
The AUTONICS CT6M-2P4 is designed for long-term, reliable operation with minimal maintenance.
- Cleaning: Use a soft, dry cloth to clean the display and housing. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check wiring connections for tightness and signs of damage.
- No User Serviceable Parts: Do not attempt to open or repair the unit. Refer all servicing to qualified personnel.
8. Troubleshooting
If the device does not operate as expected, perform the following basic checks:
- No Power/Display Off:
- Verify the power supply voltage is within the 100-240 VAC range.
- Check power wiring connections for continuity and proper terminal contact.
- Incorrect Counting/Timing:
- Ensure input sensor/signal is correctly wired and functioning.
- Verify the input type (PNP/NPN) setting matches the sensor.
- Check preset values and prescale settings.
- Confirm the operating mode (counter/timer) is correctly selected.
- Output Not Activating:
- Check output wiring to the load device.
- Verify the load device is functioning correctly.
- Ensure the preset value has been reached and the output condition is met.
If problems persist after performing these checks, contact AUTONICS technical support or your local distributor for assistance.
