3. Setup and Installation

The GR2001-E/S-277-DUAL relay is designed for wall mount installation. Ensure the mounting location is secure, dry, and provides adequate ventilation. Installation must be performed by qualified personnel in accordance with all applicable electrical codes.

1. Mounting: Securely mount the unit to a wall using appropriate fasteners through the designated mounting holes. Ensure the unit is level and stable.
2. Wiring: This unit operates on 277 Volts and uses wired electric power. All connections should be made using screw-type connectors as indicated on the unit's internal wiring diagram (refer to the diagram inside the unit cover, if applicable).
3. Power Sources: Connect both normal and emergency power sources to the designated terminals. Verify that all connections are tight and secure to prevent loose contacts and potential hazards.
4. Load Connection: Connect the lighting load to the output terminals. Ensure the total connected load does not exceed the relay's output rating to prevent overload.
5. Verification: After all connections are made, double-check wiring against the provided diagrams and ensure all safety precautions have been observed before restoring power.

4. Operating Instructions

The GR2001-E/S-277-DUAL Emergency Shunt/Control Relay operates automatically. Its primary function is to ensure that connected lighting circuits are supplied with full power during an emergency event, overriding normal control.

• Normal Operation: Under normal conditions, the relay allows the lighting circuit to operate as controlled by its regular switch or control system.
• Emergency Operation: In the event of a power failure or activation of an emergency signal, the relay will automatically shunt the lights to full brightness, bypassing any dimming or off states. This ensures emergency illumination is provided when needed.
• Automatic Reset: Once normal power is restored and the emergency condition clears, the relay will automatically return to its normal operating state, allowing the lighting circuit to be controlled as usual.

5. Maintenance

Regular maintenance helps ensure the longevity and reliable operation of your GR2001-E/S-277-DUAL relay. All maintenance should be performed by qualified personnel with power disconnected.

• Periodic Inspection: Annually inspect the unit for any signs of physical damage, loose connections, or overheating.
• Cleaning: Keep the exterior of the unit clean and free from dust and debris. Do not use liquid cleaners directly on the unit.
• Functional Testing: Periodically test the emergency shunt function according to local building codes and safety regulations to ensure it activates correctly.

6. Troubleshooting

If the GR2001-E/S-277-DUAL relay does not operate as expected, consider the following common issues:

• No Emergency Activation:
  • Verify that both normal and emergency power sources are correctly connected and active.
  • Check the emergency signal input for proper operation.
• Lights Not Shunting to Full Brightness:
  • Ensure the total connected load does not exceed the relay's rated capacity.
  • Inspect output wiring for loose connections or damage.
• Unit Not Returning to Normal Operation:
  • Confirm that the emergency condition has cleared and normal power has been fully restored.

For issues not resolved by these steps, or for any internal repairs, contact a qualified electrician or the manufacturer's support.
