4. Setup and Installation
Installation of the Blodgett R2506 Time Relay Kit requires electrical expertise. It is strongly recommended that installation be performed by a qualified service technician to ensure proper function and safety.
4.1 General Installation Guidelines
- Disconnect Power: Before beginning any installation, ensure the oven is completely disconnected from its power source.
- Access Panel: Locate and open the access panel on your Blodgett K4, K5, or K7 oven where the existing time relay is situated or where the new relay is to be installed.
- Identify Components: Carefully identify the existing relay (if replacing) and its associated wiring. Take photos for reference if needed.
- Mounting: The relay is designed for panel mounting. Secure the new R2506 relay firmly in the designated mounting location within the oven's control panel.
4.2 Wiring Connections
The R2506 Time Relay uses screw-type connectors for secure electrical connections. Refer to the wiring diagram provided with your specific oven model or the relay kit for precise connection points. Ensure all connections are tight and correct to prevent electrical hazards or malfunction.

4.3 Post-Installation Check
After installation, secure the access panel. Before restoring power, double-check all connections and ensure no tools or loose items are left inside the oven's control area. Restore power and test the oven's timed functions to confirm proper operation of the new relay.
5. Operation
The Blodgett R2506 Time Relay operates automatically, as indicated by its specifications. Its primary function is to control the duration of specific oven cycles or components based on pre-set timing parameters.
5.1 Basic Functionality
Once installed and powered, the relay receives signals from the oven's control system to initiate a timed sequence. It then maintains a circuit connection for the programmed duration before automatically switching off or on, depending on its specific role within the oven's operation.
5.2 Setting the Timer
The R2506 relay features an adjustable dial (visible in Figure 4) that allows for setting the desired time delay or duration. The specific range and increments for timing adjustments will be marked on the dial itself. Consult your oven's main user manual for instructions on how to calibrate or set the timing for specific cooking programs or functions that utilize this relay.
6. Maintenance
The Blodgett R2506 Time Relay Kit is designed for minimal maintenance. However, periodic inspection can help ensure its longevity and reliable performance.
- Visual Inspection: Annually, or as part of routine oven maintenance, visually inspect the relay for any signs of physical damage, discoloration from overheating, or loose connections.
- Cleaning: Ensure the area around the relay is free from dust, grease, and debris. Use a dry, soft cloth or a gentle brush to clean the exterior of the relay. Do not use liquid cleaners directly on the component.
- Professional Servicing: Any internal issues or suspected malfunctions should be addressed by a qualified service technician. Do not attempt to open or repair the relay yourself.
7. Troubleshooting
If the oven's timed functions are not operating correctly, the time relay may be a contributing factor. Always ensure power is disconnected before inspecting components.
| Problem | Possible Cause | Solution |
|---|---|---|
| Timed function does not activate. | No power to relay, faulty wiring, relay failure. | Verify power supply to the oven. Check all wiring connections for tightness and continuity. If connections are good, the relay may need replacement by a qualified technician. |
| Timed function activates but does not turn off. | Relay contacts stuck, internal relay failure. | This indicates an internal fault with the relay. Replacement by a qualified technician is required. |
| Inaccurate timing. | Incorrect dial setting, internal relay calibration issue. | Ensure the dial is set correctly according to oven specifications. If the issue persists, the relay may be faulty and require replacement. |
| Burning smell or visible damage. | Overheating, short circuit, component failure. | Immediately disconnect power. Do not attempt to operate the oven. Contact a qualified service technician for inspection and repair/replacement. |
For issues not listed above, or if troubleshooting steps do not resolve the problem, contact Blodgett customer support or a certified service technician.
