WARNING: TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE INSTALLING
THE DEVICE OR POWER/SLAVE PACKS.
LOAD TYPES
Use the DCLV2 for these load types:
• 0 to 10V electronic dimming ballasts (Mark 7 or equivalent)
with maximum of up to 50mA.
• Compatible LED systems (verify compatibility with LED control
manufacturer).
TERMINAL BLOCK
The DCLV2 has a wiring terminal block with 7 positions:
1 24VDC input
2 Common
3 0–10V Violet
4 Sensor input
5 Control Output
6 0–10V Gray
7 Common
DIMMING MODE
The DCLV2 supports low-voltage DC dimming, using Class 2
wires. Multiple circuits can use the same dimming signal without
additional power equipment.
0–10V Dimming curves
To accommodate various types of ballasts, the DCLV2, executes
a straight proportional relationship between the internal level and
the voltage provided, 0.6VDC to 9.5VDC.
0–10V Dimming (with ON/OFF option)
• When the user ramps up, relay 1 output
switches from 0V to 24VDC. This closes
the power pack relay to supply line
voltage to the light fixtures.
• When the user ramps down and the
0–10V output becomes 0V, relay 1
switches to 0V. This opens the power
pack relay to remove power to the
light fixtures. This allows the ballast to
smoothly ramp down and then be turned
OFF.
NOTE: An ON to OFF transition can take
longer than expected (by about 2
seconds) because the DCLV2 is
dimming down. The OFF to ON
transition is immediate.

NOTES
Any BZ series power pack will work with the DCLV2, but the
following should be noted
• The Orange, Brown, and Gray wires on the BZ-150 and
BZ-250 are not used and should be capped
• The Manual/Auto On switch on the BZ-150 and BZ-250
should be left in the Auto-On position. Manual functionality is
handled by the DCLV2.
• The BZ-200 and BZ-250 must be grounded to ensure signal
integrity,not for safety ground.
