Notice: When planning your installation, make sure to leave space around the cabinet for entry and exit wire conduit. Emergency line and neutral conduit may require extra space due to increased bend radius requirements for larger cables.

Emergency Lighting Transfer System User Manual 9

10

Planning wire entry into the ELTS cabinet

The Emergency power connections must enter the cabinet from the top or side of the cabinet within six inches of the top left corner.

Control, Normal power sensing and options wires connect most easily if they enter above the Remote station terminal or just below the Emergency sensing terminal on the left side of the cabinet.

Note: Do not run the control, normal power sensing and options wiring in the same conduit as Emergency phase or load power wiring.

Load wires in from the dimmer rack and out to the lighting loads connect most easily if they enter through the bottom of the cabinet either between or beside the transfer switch assemblies.

Note: Except for the emergency power supply wires, which must enter near the top left corner of the cabinet, recommended conduit entry locations may be changed based on the requirements of your installation.

Testing

Before you power up for the first time

Checking transfer switch operation manually

By checking transfer switch manual operation before you apply power, you reduce the possibility of failure caused by mechanically frozen, damaged or obstructed switches. Each switch should rotate without catching or binding.

Warning! Normal and Emergency power should be off when you open the ELTS cabinet for to check switch operation. Opening the cabinet with power applied exposes you to death or injury from electrical shock.

1.

Open the ELTS cabinet.

Warning! Rotating the transfer switch assemblies manually with Normal or Emergency power applied may result in the assemblies switching automatically, causing severe hand injuries.

2.

Turn the manual operation handle 90

° clockwise. E (Emergency) should be visible on the assembly about 1.5 inches above the handle.

3.

Rotate the handle 180

° counter-clockwise. N (normal) should be visible.

Note: If you have difficulty operating the switch, check for installation debris that may be blocking switch operation.

4.

Repeat steps 2 and 3 with the remaining transfer switch assemblies.

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.
