Emergency Lighting Transfer System User Manual 19 Automatic function The automatic function tests the ELTS’s ability to switch back and forth from Normal to Emergency when Normal power is interrupted or restored. 1. Make sure the NORMAL OPERATION LED is lit on the ELTS front panel. 2. Turn off the normal power to the dimmer rack connected to the ELTS. The NORMAL OPERATION and NORMAL POWER STABLE LEDs on the ELTS front panel goes out and the ELTS switches to Emergency power (the EMERGENCY OPERATION and EMERGENCY POWER STABLE LEDs light, and the emergency loads go to full brightness.) If Emergency power is provided by an engine/generator, there will be a short delay before switching as the generator turns on and the voltage and frequency stabilize. 3. Turn the Normal power back on. The ELTS switches back to Normal power after the retransfer delay times out (the default setting is one minute). On the front of the ELTS, the EMERGENCY OPERATION and EMERGENCY POWER STABLE LEDs turn off and the NORMAL OPERATION and NORMAL POWER STABLE LEDs light. If used, the Emergency power engine/generator turns off when the cool down time is complete. Options function ELTS systems can also be activated by fire alarm and auxiliary circuits. Both are operated by a normally closed circuit controlled by the fire alarm or auxiliary relays. When the fire alarm or auxiliary circuit activates, the relay opens, causing the ELTS to switch to Emergency power. To test option relay function, either: ▼ Activate the fire alarm or auxiliary relay. The ELTS should switch to Emergency power and the emergency loads should go to full. ▼ If you do not wish to activate the fire alarm or auxiliary circuit, generate an open circuit at the ELTS connection to the fire alarm or auxiliary circuit by disconnecting one of the two wires to the ELTS cabinet. The ELTS will switch to Emergency power and the emergency loads should go to full. Note: The second method tests the ELTS response to an open circuit, but does not confirm the fire alarm or auxiliary relay’s ability to open the circuit to the ELTS. 20 Electronic Theatre Controls, Inc.
