UNIT DESCRIPTION
The DM-105-WP is a control module that is used to switch HID (High Intensity Discharge) lamps
from high to low and from low to high. The DM-105-WP includes a rugged weatherproof housing
for outdoor mounting applications. The DM-105-WP bases its bi-level switching on signals
received from a controlling device (see below).
With the DM-105-WP and a motion sensor, HID lighting will switch to a lower, energy saving light
level (high to low) after a space becomes unoccupied. When the space is again occupied, lighting
returns to full brightness (low to high).
Upon initial power up of HID lamps, or after a power failure or phase drop, the DM-105-WP
supplies full power for a 15 minute lamp warm-up. Then, lighting either remains at full level if the
space is occupied, or goes to the low level if unoccupied.
The DM-105-WP'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
unneeded. This saves energy and adds convenience.
Controlling Devices
One or more controlling devices (such as the EW-105-24, or EW-205-24 motion sensor) must be
used to control a DM-105-WP. A single motion sensor can provide control for up to two
DM-105-WP modules. (See Control Wiring on page 5). One DM-105-WP is required for each
ballast.
A controlling device must:
1. Have its own power supply, or be able to be powered by the +24VDC output from a
DM-105-WP.
2. Provide a +24VDC control output to the DM-105-WP.

easily accessible. Follow proper safety procedures to discharge the installed capacitor inside the
ballast housing.
2. Open a 1/2" knockout hole in the ballast housing where the DM-105-WP will attach.
3. Unscrew the metal conduit lock ring from the DM-105-WP box. The rubber washer might be
removed along with the lock ring; if so, replace the washer around the wires coming out of the
DM-105-WP.

1. Refer to the wiring diagrams on the following page.
Connect WHITE/BLUE wire from the DM-105-WP to the B terminal on the bi-level capacitor.
Connect WHITE wire from the DM-105-WP to the C terminal on the bi-level capacitor;
from the same terminal complete the connection to the ballast with the WHITE wire.
Connect WHITE/ORANGE wire from the DM-105-WP to the A terminal on the bi-level capacitor.
Connect GREEN wire from the DM-105-WP to the fixture ground.
Connect BLACK wire to:

2. Reassemble the ballast housing, being careful not to pinch wires.
3. Motion sensor(s) can be attached to the pole at this time or after the fixture is installed.
4. Mount the fixture with the installed DM-105-WP and motion sensor. Balance the fixture if
needed.
5. Reconnect the power cord to the fixture (power should be off at the circuit breaker).

CONTROL WIRING
After the DM-105-WP is installed and the fixture is mounted, low voltage control wire connections
can be made to the DM-105-WP. All low voltage control wires are in the 10’ black cable
connected to the DM-105-WP.
Make connections before the fixture’s power is restored. When all connections are made,
continue to Testing.

TESTING
1. After the installation is complete and checked, turn on the main power to the fixture circuits and
turn on any controlling switches.
• The DM-105-WPs 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 motion sensor control: Lamps that are controlled by a motion sensor will go to low if no
motion 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. Remain still until the time delay
elapses. The lights should go to low.
3. Verify that other conntrolling devices turn the lamps to low as desired.
TROUBLESHOOTING
General checks:
• Wires make proper contact.
• Wires are connected to correct terminals or connector leads.
• High voltage DM-105-WP wires are securely connected.
• Wiring of switch, motion sensor or other control devices to DM-105-WP is correct.
• Motion sensor adjustments: sensitivity and light level (if applicable), sensor alignment.
Lights do not turn on
• Check breakers, fuses.
• Check light level setting on motion sensor for proper adjustment.
• Check motion sensor detection.
• Check that 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-105-WP group turn on but others do not
• Check the DM-105-WP 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 correct.
• 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-105-WP group remain on high
• Check to see if something is giving an “on” input to the DM-105-WPs.
• Check controlling devices and connections to the DM-105-WPs.
• Check light level setting on motion sensor for proper adjustment.
• Check motion sensor detection.
Lights remain on low
• The “on” input from the controlling device is not reaching the DM-105-WP group.
• Check controlling devices and connections to the DM-105-WPs.
• Check light level setting on motion sensor for proper adjustment.
• Check motion 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.
• Check main power supply.
• Check breakers, fuses and that HID fixtures are plugged in.
• Check for energy management systems or building controls that affect power to the lights.
Motion sensor not detecting
• Refer to sensor’s installation instructions for proper adjustment and troubleshooting.
