3. Package Contents
The package should contain the following item:
- 1x Came 119RIR090 Transformer
4. Setup and Installation
The Came 119RIR090 Transformer is designed for frame mounting within the compatible Came control unit enclosure. Follow these steps for proper installation:
- Power Disconnection: Ensure the main power supply to the gate automation system is completely disconnected at the circuit breaker before beginning any work.
- Access Control Unit: Open the enclosure of your Came control unit (e.g., BX, ZA3, ZA4, ZA5, ZC5, ZF1, ZBX74) to access the internal components.
- Mounting: Securely mount the 119RIR090 transformer to the designated frame mounting points within the control unit enclosure. The transformer's dimensions are approximately 3.07 x 1.4 x 1.4 cm.
- Wiring Connections: Carefully connect the transformer's primary and secondary wires to the corresponding terminals on the control unit's circuit board. Refer to your specific control unit's wiring diagram for exact terminal assignments. The transformer typically provides 12V/24V output.
- Secure Wires: Ensure all wires are securely fastened and routed to prevent pinching or damage.
- Close Enclosure: Once all connections are verified, close the control unit enclosure.
- Restore Power: Restore power to the gate automation system at the circuit breaker.

5. Operation
The Came 119RIR090 Transformer operates passively, converting the incoming AC voltage to the required lower voltage for the gate automation control unit. Once correctly installed and powered, it will continuously supply the necessary voltage to the system.
- After installation, verify that the gate automation system functions correctly according to its own operational manual.
- Listen for any unusual noises or observe any abnormal behavior from the transformer or control unit.
6. Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your transformer and gate automation system.
- Periodic Inspection: Annually inspect the transformer and its connections for any signs of wear, corrosion, or loose wiring.
- Cleanliness: Keep the control unit enclosure clean and free from dust, debris, and insects, which can impede proper ventilation and lead to overheating.
- Professional Check: Consider having a qualified technician perform a comprehensive check of your gate automation system, including the transformer, every few years.
7. Troubleshooting
If you experience issues with your gate automation system, the transformer may be a contributing factor. Here are some common problems and potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to control unit | Loose wiring, faulty transformer, tripped circuit breaker | Check all connections, verify circuit breaker, test transformer output with a multimeter (if qualified). |
| Transformer becomes excessively hot | Overload, poor ventilation, internal fault | Ensure proper ventilation, check for short circuits in the system, replace transformer if faulty. |
| Intermittent system operation | Unstable power supply from transformer, loose connections | Inspect wiring for intermittent contact, test transformer output stability. |
If troubleshooting steps do not resolve the issue, contact a qualified technician or Came customer support.
