DESCRIPTION

The DM-100 is a control module which is used to switch HID (High Intensity Discharge) lamps

from high to low and from low to high. The DM-100 bases its bi-level switching on signals

received from a controlling device (see “Controlling Devices” below).

With the DM-100 and an occupancy sensor, HID lighting will switch to a lower, energy saving

light level (high to low) after a space becomes unoccupied. Then, as soon as the space is

occupied, lighting will return to full brightness (low to high).

Upon initial power up of HID lamps, or after a power failure or phase drop, the DM-100 supplies full

power for a 15 minute lamp warm-up. Then lighting will either remain at full level if the space is

occupied, or go to low level if unoccupied.

The DM-100's bi-level switching avoids the warm-up problem otherwise found when controlling

HID fixtures. The switching is immediate and lights are no longer left on at 100% when lighting is not

needed. This saves energy and adds convenience.

Controlling Devices:

• One or more controlling devices (such as occupancy sensors, time switches, photocells, etc.)

must be used to control a DM-100. The control to this DM-100 can be extended to other

DM-100s by connecting them into control groups (see Control Wiring section).

• A controlling device must:

1. Have its own power supply or be able to be powered by the +24VDC output from a DM-100.

2. Provide a +24VDC control output to a DM-100 in the controlled group.

INSTALLATION AND WIRING

1. IMPORTANT: Verify that the ballast is a CWA (Constant Wattage Autotransformer) and that

the DM-100 model# is correct for the lamp ANSI and original capacitor rating (see Ordering

Information section).

2. Unplug and move the HID light fixture to a stable, secure work area.

3. DANGER: The fixture’s capacitor may contain a stored high voltage charge. Carefully open

the ballast housing so that the ballast and capacitor are easily accessible.

Follow proper safety procedures to discharge the installed capacitor inside the ballast housing.

4. Open a 3/4" knockout hole in the ballast hanger box where the DM-100 will attach (either

directly or by conduit):

If connecting directly to the box:

- Thread the DM-100’s wires into the knockout hole and through the 3/4" lock ring (supplied).

- Secure the DM-100’s threaded nipple on the inside with the lock ring.

- Thread the DM-100’s wires down into the ballast housing.

If connecting with conduit:

- Thread the DM-100’s wires into and out the other end of the conduit.

- Attach the conduit to the DM-100’s threaded nipple.

- Thread the DM-100’s wires into the knockout hole and secure the conduit to the knockout hole.

- Thread the DM-100’s wires down into the ballast housing.

5. Disconnect the wires from the original capacitor. Cut off the end connectors and strip the

wires. NO CONNECTIONS WILL BE MADE TO THE ORIGINAL CAPACITOR.

6. With a supplied wire nut, connect one of the black wires from the DM-100 to one of the

wires that was disconnected from the original capacitor (it doesn’t matter which one).

Connect the other DM-100 wire to the remaining disconnected wire (see the wiring

diagrams on the next page).

7. Reassemble the ballast housing, being careful not to pinch wires.

8. An occupancy sensor can be attached to the reflector bell at this time or after the fixture is

rehung.

9. Replace the fixture with the installed DM-100 and occupancy sensor back to the fixture’s

mounting location. Balance the fixture, if necessary.

10. If the DM-100 is mounted separately, secure it to its location.

11. Reconnect the power cord to the fixture (power should be off).

12. Once the steps above are completed, continue to the Control Wiring section.

DM-100 WIRING

CONTROL WIRING

After the DM-100 is installed and the fixture has been remounted, low voltage control wire

connections can be made to the terminal block, located on the side of the DM-100.

Make connections before the fixture’s power is restored. When all connections are made,

continue to the Testing section.

To insert or remove wires: Use a small flat-blade screwdriver to

push in the plunger, insert wire, then release plunger (see left).

If using stranded wire, make sure all the strands are inserted.

IMPORTANT: Verify that enough insulation is removed (3/8"–1/2") at

the end of wires so that when inserted, a proper connection will be

made.

Occupancy sensors: (typical connections)

1. Connect the sensor’s +24VDC Input lead to

the +24VDC OUT on the DM-100.

2. Connect the Common lead from the sensor

to the COMMON on the DM-100.

3. Connect the Control Output lead from the

sensor to a CONTROL IN on the DM-100.

Large Zone Control:

DM-100s can be connected to control more than 100 lighting fixtures. When one or more

controlling devices are used in large zone control applications, the following recommendations

and wiring diagram should be followed:

• To avoid voltage drop issues:

• Use the heaviest gauge wire possible. We recommend 18-20AWG.

• Wire the DM-100s serially and sequentially to avoid long wire runs.

• If the controlling device is located a long distance away from the controlled zone, test the

installation first with only a few DM-100s to ensure there are no problems.

OCCUPANCY SENSOR BRACKET

The MB-2 occupancy sensor bracket allows sensors to be mounted to the rim of metal HID

reflector bells (with no installed covers).

This bracket secures to the rim with three clamping screws and has an adjustable mounting

plate that allows rotation of the sensor to a desired angle for optimal coverage.

The MB-2 bracket is designed to be used with CX and CI sensors. The bracket comes with an

extension wire to connect the sensor to the DM-100, as well as mounting screws to attach the

sensor to the bracket. A bubble level is attached to the bracket to assist accurate sensor

adjustment. (See separate MB-2 installation instructions).

Small Control Groups:

•A controlling device can be extended to other DM-100s by linking the DM-100s together

into a control group.

•A control group starts from the first DM-100 connected. All other DM-100s connected to this

DM-100 (radially or in a series) are part of this group and controlled by the originating

device(s).

•Groups can overlap. DM-100s can be part of more than one control group.

•When multiple controlling devices are used, only one signal is needed to turn the DM-100s

to high.

TESTING

1. After the installation is complete and checked, turn on the main power to the fixture circuits

and turn on any controlling switches.

Note: The DM-100s will supply full power to the HID lamps for 15 minutes for the lamp

warm-up. After the warm-up time has elapsed, the lamps can go to low.

2. To test occupancy control: Lamps that are controlled by an occupancy sensor will go to

low if no occupancy has been detected and the sensor’s time delay has elapsed. Turn off all

other controlling devices to the sensor controlled lamps. Set the time delay on the sensor to

minimum, then move into the coverage area for the sensor, and remain still until the time

delay elapses. The lights should go to low.

3. To test switch control: Turn the switch off. If occupancy sensors are also controlling the

DM-100s, remain still and allow the time delay to elapse. Turn the switch back on and the

lights should go to high.

4. Verify that other on/off input devices turn the lamps to low, as desired.

TROUBLESHOOTING

General checks:

•Terminal block wires make proper contact.

•Terminal block wires are connected to the correct terminals.

•High voltage DM-100 wires are securely connected.

•Wiring of switch, occupancy sensor or other controllers to the DM-100 terminal block are correct.

•Occupancy sensor adjustments needed: sensitivity and light level (if applicable), alignment.

•Light level detector (photocell), if any, adjustment needed.

Lights do not turn on:

•Check breakers, fuses.

•Check photocells for proper adjustment and orientation (if installed).

•Check occupancy sensor detection.

•Make sure switches and control systems are on.

•Make sure HID fixtures are plugged in.

•Follow proper high voltage safety procedures and check wiring and connections in the ballast

housings.

Some lights in a DM-100 group turn on, but others do not:

•Check the DM-100 connections to a fixture that does not turn on in a connected group.

- Verify that proper wire contact is being made in the terminal block.

- Verify that connections are made to the correct terminals.

•Verify that the bulb has not burned out.

•Make sure you follow the recommendations found in the Control Wiring section.

All lights in a DM-100 group remain full on:

•Something is giving an ON input to the DM-100s.

•Check switching controllers and systems, as well as connections, to the DM-100s.

•Check photocells for proper adjustment and orientation (if installed).

•Check occupancy sensor detection.

Lights remain dimmed:

•The ON input from controllers is not reaching the DM-100 group.

•Check switching controllers and systems, as well as connections, to the DM-100s.

•Check photocells for proper adjustment and orientation (if installed).

•Check occupancy sensor detection.

All lights turn off:

•The main power is being turned off to the lights. The main power should be turned off only when

intending to completely turn off the lights. Remember, there is a restrike/warm-up period before

the lights will return to full brightness.

Occupancy sensor is not detecting motion:

•Refer to the sensor’s installation instructions for proper adjustment and troubleshooting.
