Mounting the ELTS cabinetMount the ELTS on a load-bearing wall, in a location where it will not be subject to tampering or vandalism. If possible, install the ELTS where it is most secure from damage by a fire, flood or other incident likely to require its use. Do not install the ELTS inside any other electrical enclosure.

Physical requirements for mountingYou must mount either size ELTS cabinet with sufficient front clearance (30 inches) to allow the door to open completely.

Figure 5: ELTS cabinet mounting dimensions

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.

Planning wire entry into the ELTS cabinetThe 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.

Mounting the cabinetAfter determining where you want to install the cabinet, follow these instructions.

1. Install two 3/8" bolts 24.25 inches apart for the lower two support slots (the installer must supply the mounting hardware).

2. Use the mounting dimensions from Figure 5 : ELTS cabinet mounting dimensions on page 9 to drill the holes for the upper two 3/8" bolts.

3. Place the ELTS cabinet on the wall supported by the two lower bolts.

Notice: ELTS cabinets are very heavy. Make sure you have adequate equipment (or help) to lift the cabinet into place and support it while you secure the top two bolts.

4. Secure the ELTS to the wall with the two upper 3/8" bolts.

Installing Remote stations (optional)1. Install a standard two gang backbox (4" x 4" x 3.5") and run wire conduit

from it to the ELTS cabinet.

2. Pull five conductor, Class 2 (12 Vdc) wiring through from the backbox to the cabinet.

3. Connect the wires to the terminal strip on the back of the remote station. Note which terminal each wire connects to.

4. Install the Remote station onto the backbox with four 6 - 32 x 1/2" oval head machine screws (provided).

5. To install multiple Remote stations, repeat steps 1 – 4, wiring in parallel between Remote station terminal blocks.

TestingBefore 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.

Turn on systemVoltage checkout1. Apply power to the ELTS and connected dimmer rack at the main circuit

breaker. The green Normal LED lights.

2. Apply emergency power. The red Emergency light turns on.

Warning! ELTS voltage tests should only be performed by qualified personnel using EXTREME caution. Opening the cabinet with power applied exposes you to death or injury from electrical shock.


4. Use a digital voltmeter (DVM) to test the feed voltage at the Normal power sensing terminal block (Figure 12 on page 15 for location). Phase A is on terminal 1, phase B on terminal 3 and phase C on terminal 5. Voltage must be within 10 percent of the rated voltage for the ELTS.

5. Use the DVM to test the feed voltage at the Emergency power lugs. Phase lugs are labeled either A, B or C. Voltage values must be within 10percent of the rated voltage for the ELTS.

6. Close the ELTS cabinet.


Functional checkoutAfter verifying the Normal and Emergency voltages, check the ELTS system functions.

Figure 16: Local control operation and LED indications

Switch function1. Insert the key into the keyswitch on the front panel of the ELTS.

2. Turn the key to EMERGENCY POWER. The red light above EMERGENCYOPERATION turns on and the emergency loads go to full brightness. If Emergency power is provided by an engine/generator, there will be a short delay as the generator turns on and the voltage and frequency stabilize.

3. Release the key. The keyswitch returns to AUTO (center) and the EMERGENCY OPERATION light remains on.

4. Turn the key to the NORMAL POWER position. The green light below NORMAL OPERATION turns on if the system is functioning correctly.

5. Release the key. The keyswitch returns to AUTO and the NORMALOPERATION light remains on.

Remote switch functionsAfter confirming correct function of the keyswitch on the front of the ELTS cabinet, repeat the switch function checkout procedure at EVERY remote station installed on your system.

Automatic functionThe 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 NORMALOPERATION and NORMAL POWER STABLE LEDs light. If used, the Emergency power engine/generator turns off when the cool down time is complete.

Options functionELTS 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.


SettingsELTS timing settings

ELTS timing settings for momentary outage override, transfer to Emergency delay, return to Normal delay, and generator cool down are set at the factory. You can adjust settings for specific applications any time after installation.

Caution: Only make changes to ELTS timing settings if you are familiar with the system and know the reason for making the change.

Table 3: ELTS timing settings

Getting access to the ELTS control panel To make adjustments, you must access the ELTS control panel.

1. Disconnect Normal and Emergency power to the ELTS.

Warning! Opening the ELTS cabinet with power on may result in death or injury from electrical shock.


3. Release the two latches on the control panel cover and remove it. See Figure 17, left.

Changing the momentary outage overrideThe momentary outage override is the interval the ELTS will tolerate a Normal power voltage fault without switching to Emergency power. It can be set from 0.5 to 6 seconds using adjustment potentiometer P4.

1. Follow the instructions on page 21 to remove the control panel cover.

2. Locate P4 using Figure 18 : Adjustment potentiometer and DIP switch locations on page 21.

3. Turn P4 clockwise to increase the interval or counterclockwise to decrease it. P4 has a 270 adjustment range.

Note: Potentiometer adjustments change timing as a fractions of the adjustment range. For example, turning the pot half its range changes the timing value by 50%. You will need to use some trial and error and a timing device to achieve exact values.

Figure 19: Changing adjustment potentiometer settings

Changing the Transfer to Emergency delayThe Transfer to Emergency delay sets the time the ELTS waits before switching to Emergency after the Emergency power voltage and frequency stabilize. You can set the delay in two time ranges, from zero to 60 seconds or zero to 8 minutes, using DIP switch SW2 and adjustment potentiometer P2.


2. Locate SW2 using Figure 18 : Adjustment potentiometer and DIP switch locations on page 21.

3. To select the zero to 60 second adjustment range put SW2 up. To select the zero to 8 minute range, put SW2 down.


5. After setting the range, turn P2 clockwise to increase the interval or counterclockwise to decrease it. P2 has a 270 adjustment range.

Changing the Return to Normal delayThe Return to Normal delay sets the time the ELTS waits before switching from Emergency to Normal after Normal power is restored. The delay can be turned off, or set from 0.5 to 30 minutes using DIP switch SW1 and adjustment potentiometer P1.

Note:To disable the delay on a one-time basis (to quickly restart an interrupted performance or for testing purposes) switch the ELTS back to Normal with the front panel Local switch or a Remote keyswitch station.



3. To turn off the delay put SW1 up. To set the range from 0.5 to 30 minutes, put SW1 down.

4. If SW1 is down, locate P2 using Figure 18 : Adjustment potentiometer and DIP switch locations on page 21.

5. Turn P2 clockwise to increase the interval or counterclockwise to decrease it. P2 has a 270 adjustment range.

Changing the Generator cool down intervalThe Generator cool down interval sets the time the ELTS waits before shutting off the Emergency power generator after switching back to Normal power. It can be set from zero to 8 seconds or 0.5 to 30 minutes using DIP switch SW3 and adjustment potentiometer P3.

Caution: Consult your generator user manual for proper cool down times before changing the Generator cool down interval.



3. To make the adjustment range zero to 8 seconds put SW3 up. To make the range 0.5 to 30 minutes, put SW3 down.


5. After setting the range, turn P3 clockwise to increase the interval or counterclockwise to decrease it. P3 has a 270 adjustment range.


ELTS voltage and frequency settingsVoltage and frequency settings are set at the factory and should only be adjusted by an authorized ETC representative.

OperationAutomatic operation

During automatic operation the ELTS system switches back and forth from Normal to Emergency when either power supply is interrupted or restored.

Figure 21: Local control LED indications

Selecting the preferred power source: Normal or EmergencyUsing the local keyswitch on the front of the ELTS cabinet or a Remote keyswitch station installed in your facility, you can select either Normal or Emergency as the preferred power source.

1. Insert the key into the keyswitch and select the desired power source:

▼ To select Normal power, turn the key left. The green NORMALOPERATION LED lights.

▼ To select Emergency power, turn the key right. The red EMERGENCYOPERATION LED lights and the emergency loads go to full. If Emergency power is provided by an engine/generator, there will be a short switching delay as the generator turns on and voltage and frequency stabilize.

2. Release the key. The keyswitch returns to center and the indicator light you selected remains on. The ELTS uses the selected power source. If the selected source’s voltage or frequency drops below the limit, the ELTS will switch to the other source.

3. When the voltage and frequency of the selected source returns to acceptable levels, the ELTS will switch back to it.

Remote StationRemote Keyswitch station operation is identical to the local station. Refer to Selecting the preferred power source: Normal or Emergency for instructions.

Fire alarm or Aux signal switchingIf desired, the ELTS system can be activated by fire alarm or auxiliary circuits. When the ELTS receives the fire alarm or auxiliary circuit activation, it will switch to Emergency power.

Note: If you have selected Emergency as the preferred power with either the Local or Remote keyswitch, the ELTS will not switch power sources after receiving a fire alarm or auxiliary activation.

TroubleshootingIf you have trouble with an installed ELTS system, you can contact ETC Technical Service at 800/775-4382.

Warning! Trouble shooting usually involves opening the ELTS cabinet and metering voltages. Opening the ELTS cabinet with power applied exposes you to death or injury from electrical shock. Use extreme caution during all troubleshooting activities.

Emergency or Normal Power Stable LED does not turn on properlyDuring normal operation, either the Normal Power Stable or Emergency Power Stable LED should be lighted. If one or the other does not light, the problem may be with the LED, Normal or Emergency sensing wiring, or Normal or Emergency power.

1. Switch between Normal and Emergency power on the ELTS control panel keyswitch and observe the results. The ELTS should switch between Normal and Emergency power.

▼ The ELTS switches between Normal and Emergency

1. Check for loose LED wire connections or defective LEDs.

2. Make sure the Control Panel connector is properly seated.

▼ The ELTS does not switch between Normal and Emergency. Go to the next ELTS troubleshooting section.

The ELTS will not switch between Normal and EmergencyIf the system will not switch from Emergency power1. check for tripped Normal power sensing wire circuit breakers.

2. If the circuit breakers are not tripped, meter Normal power using the procedures in Voltage checkout on page 18.

If the system will not switch from Normal power1. Meter Emergency power using the procedures in Voltage checkout on

page 18.

2. If no fire alarm or auxiliary circuits are connected to the ELTS, make sure the terminal jumpers are in place.

3. If fire alarm or auxiliary circuits are connected, meter between the wires to be certain the circuit is closed. An open circuit switches the ELTS to Emergency power.

If the system does not seem to function in either Normal or Emergency power mode1. Make sure the control panel connector is properly seated.

2. Check other wire connections for loose terminals or broken wires.

3. Use the procedures in Checking transfer switch operation manually on page 18 to test the switching mechanism for mechanical problems.


Remote stations cannot switch the ELTS 1. Switch between Normal and Emergency power on the ELTS control panel

keyswitch and observe the results.

If the ELTS does not switch locallyFollow the instructions in The ELTS will not switch between Normal and Emergency on page 28.

If the ELTS switches locallyTry switching the ELTS from other Remote station, if multiple stations have been installed

1. If the other stations function, check the wire terminal connections on the problem station. See Installing Remote stations (optional) on page 11 for station connection requirements.

2. If the other stations do not function, or there is only one Remote station installed.

3. Check the wire connections on the Remote station terminal block.

4. Check the Remote station fuse in the ELTS cabinet

Figure 23: Locating the Remote station fuse5. Inspect the wiring between the ELTS cabinet and the stations for defects.

See Connecting Remote stations to the ELTS on page 16 for ELTS connection requirements.

Some ELTS circuits do not switch when the system changes sourcesPartial switching of ELTS circuits indicates one or more transfer switch assemblies, or the wiring to them, is defective.

1. Use the procedures in Checking transfer switch operation manually on page 18 to locate any transfer switch assemblies that have not switched and to manually test their function.

2. If an assembly cannot be switched manually, check for something that could be physically obstructing it. If you find something, remove it and manually test the switch again. If you cannot find and remove the cause of the switching failure, the assembly is defective and must be replaced.

3. If the assembly switches manually, check for loose wire connections to the assembly and look for damaged wires between the assembly and the control panel. Repair any wire problems you find and test the system.
