Product Overview
The ET9250 module is a compact circuit board designed to integrate seamlessly with compatible Intermatic ET90000 series controllers. It provides additional switching capabilities for your system.
Key components include:
- Four SPDT 30 Amp Relays: These relays (K1-K4) are the primary switching components, capable of handling loads up to 30 amps.
- Terminal Blocks: Screw terminals for connecting external loads, clearly marked NC, NO, and COM for each circuit.
- Wire Harness: A multi-colored wire harness for connecting the module to the main ET90000 series controller.
Installation and Setup
The ET9250 relay module is designed for integration with specific Intermatic ET90000 series controllers, including models such as ET90415CR, ET98015CR, ET91215CR, and ET91615CR. It comes in 4-circuit packs, allowing for system expansion up to a maximum of 16 circuits.
Installation Steps:
- Power Disconnection: Ensure all power to the ET90000 series controller is disconnected at the main circuit breaker before beginning installation.
- Access Controller: Open the ET90000 series controller enclosure to access the internal components.
- Module Placement: Carefully align the ET9250 module with the designated expansion slot or mounting points within the controller.
- Connect Wire Harness: Connect the multi-colored wire harness from the ET9250 module to the corresponding connector on the main controller board. Ensure a secure and correct connection.
- Secure Module: Secure the module in place using any provided fasteners or clips.
- Wiring Loads: Connect the electrical loads to the NC, NO, and COM terminals on the ET9250 module as required by your application. Refer to the specific wiring diagram for your ET90000 series controller for detailed instructions.
- Close Enclosure: Once all connections are made and verified, close the controller enclosure.
- Restore Power: Restore power to the controller at the main circuit breaker.
- System Configuration: Follow the instructions in your ET90000 series controller manual to configure the newly added circuits.
Operation
The ET9250 relay module operates under the control of the main ET90000 series controller. Each of the four SPDT 30 amp relays can be programmed and controlled independently by the timer or automation functions of the primary unit. When the controller sends a signal, the corresponding relay will switch, opening or closing the circuit to which it is connected. This allows for automated control of various electrical devices or systems.
Maintenance
The Intermatic ET9250 relay module is designed for reliable, long-term operation with minimal maintenance. However, periodic inspection can help ensure continued performance.
- Visual Inspection: Annually inspect the module and its connections for any signs of damage, corrosion, or loose wiring.
- Cleanliness: Keep the controller enclosure clean and free of dust and debris, which can impede proper operation and heat dissipation.
- Environmental Protection: Ensure the module remains protected from moisture and extreme temperatures as per its operating specifications.
- Power Disconnection: Always disconnect power before performing any inspection or cleaning.
Troubleshooting
If you experience issues with your ET9250 relay module, consider the following troubleshooting steps:
- No Power to Load: Verify that the main controller is receiving power and is programmed correctly. Check the wiring connections to the ET9250 module and the load for looseness or damage.
- Incorrect Switching: Ensure the programming in the main ET90000 series controller is correct for the desired switching action. Check for any error codes or indicators on the main controller.
- Module Not Recognized: If the main controller does not recognize the newly installed module, ensure the wire harness is securely connected and that the module is properly seated. Refer to the main controller's manual for module detection procedures.
- Overload: If a relay is not switching or appears damaged, check the connected load to ensure it does not exceed the 30 amp rating of the relay.
- Professional Assistance: For persistent issues or if you are unsure about any troubleshooting steps, contact a qualified electrician or Intermatic customer support.
