- Black Polycarbonate (PC) Housing
- Loud Audible Indicator (92 dB at 1m)
- Voltage: 12-30 VDC
- Environmental Rating: IP65
- Input: Bimodal
- Termination: 5-pin M12 Integral Quick Disconnect
- Mounting: Chassis Mount
4. Setup
4.1 Unpacking
Carefully remove the TL70ALQ Tower Light from its packaging. Verify that the unit is free from damage.
4.2 Mounting
The TL70ALQ is designed for chassis mounting. Secure the threaded base of the unit into a suitable opening on the chassis. Ensure a tight and stable fit to maintain the IP65 environmental rating and prevent vibration.
4.3 Wiring
The device utilizes a 5-pin M12 integral quick disconnect for electrical connection. Follow these guidelines for wiring:
- Power Supply: Connect a 12-30 VDC power supply to the appropriate pins on the M12 connector. Ensure correct polarity.
- Bimodal Input: The TL70ALQ features a bimodal input, meaning it can accept both NPN (sinking) and PNP (sourcing) control signals. Connect your control signal to the designated input pin. The device will activate when the input signal is present.
- Refer to the specific wiring diagram provided with your M12 cable or consult Banner Engineering documentation for pin assignments.
5. Operating
The TL70ALQ functions as an audible indicator. When a valid control signal is applied to the bimodal input, the device will emit a loud audible tone. The audible output is rated at 92 dB at 1 meter.
The bimodal input allows for flexible integration with various industrial control systems, accepting either a sinking (NPN) or sourcing (PNP) signal to activate the audible alarm.
6. Maintenance
6.1 Cleaning
Periodically clean the exterior of the TL70ALQ with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the polycarbonate housing. While the IP65 rating protects against dust and low-pressure water jets, avoid direct high-pressure washing.
6.2 Inspection
Regularly inspect the M12 quick disconnect for a secure connection and any signs of wear or damage. Check the mounting for stability and ensure all connections remain tight.
7. Troubleshooting
7.1 No Audible Output
- Verify that the power supply (12-30 VDC) is connected and active.
- Check the M12 connector for secure and correct wiring, ensuring proper polarity.
- Ensure the control signal is correctly applied to the bimodal input and is within the specified voltage range.
- Confirm that the control system is functioning and sending the appropriate signal to the TL70ALQ.
7.2 Intermittent Audible Output
- Check for loose wiring connections at the M12 quick disconnect or the power source.
- Inspect the control signal for stability and proper voltage levels. Fluctuations in the control signal can cause intermittent operation.
