4. Setup and Installation

Installation must be carried out by a qualified electrician or technician in accordance with all applicable safety standards and wiring regulations.

Installation Steps:

1. Power Disconnection: Ensure all power to the machine or system is completely disconnected and locked out before beginning installation.
2. Mounting Location: Select a suitable, stable mounting surface for the interlock. Ensure it is positioned correctly relative to the guard or door it will secure.
3. Mechanical Mounting: Securely fasten the interlock unit using the provided mounting hardware. Ensure the unit is firmly attached and aligned for proper key insertion and operation.
4. Electrical Wiring: Connect the interlock to the control circuit according to the wiring diagram provided by the machine manufacturer or system integrator. Pay close attention to voltage and current ratings. The unit is rated for U: 400V / AC-15: 6A / 250VAC and 10A 300VAC. Ensure wiring is suitable for 60/75 °C.
5. Testing: After installation, thoroughly test the interlock's function to ensure it operates correctly and provides the intended safety function before re-energizing the machine.

5. Operating Instructions

The Schmersal TZG01.103 interlock functions as a safety gate monitoring device. Its operation is typically integrated into a machine's control system.

Basic Operation:

• Guard Closed/Locked: When the machine guard or door is closed and the key is inserted, the interlock allows the machine to operate. The solenoid may be energized to hold the key captive, preventing the guard from being opened while the machine is running.
• Guard Open/Unlocked: To open the guard, the machine must first be brought to a safe state. The solenoid will then de-energize (or energize, depending on the specific wiring configuration), releasing the key. Once the key is removed, the guard can be opened, and the machine's hazardous functions are prevented from operating.

6. Maintenance

Regular maintenance ensures the longevity and reliable operation of the interlock. Always disconnect power before performing any maintenance.

• Visual Inspection: Periodically inspect the interlock for any signs of physical damage, wear, or corrosion. Check for loose connections or mounting hardware.
• Cleaning: Keep the unit clean and free from dust, debris, or excessive moisture. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Functionality Check: Regularly test the interlock's function to ensure it engages and disengages smoothly and that all associated safety circuits are operating correctly.

7. Troubleshooting

If the interlock is not functioning as expected, consider the following common issues:

• Interlock Not Engaging/Disengaging:
  • Check power supply to the solenoid.
  • Verify correct wiring according to the control circuit diagram.
  • Ensure the key is fully inserted and aligned.
  • Inspect for any mechanical obstructions preventing the key or actuator from moving freely.
• Unexpected Machine Shutdown:
  • Check if the guard is fully closed and the interlock is properly engaged.
  • Inspect for loose wiring connections that might cause intermittent contact.

If issues persist after basic troubleshooting, consult a qualified technician or contact Schmersal technical support.
