This rotary switch sets the low-end cutoff point for all 4
switched hot relays in steps of 1 to 10 percent. Position
"0" selects 10%.

Three rotary switches select the DMX start address for
the card's four channels. The switches are set as hun-
dreds, tens and units. Address 000 and 001 both select
DMX address 1.

S1-S4 CONTROL BYPASS
S5 ANALOG INPUT ENABLE
When in “ON” position, all 4 analog inputs are enabled.
Each switch turns the associated output on full when in
the “ON” position.
S6 SCALED HOLD ENABLE
“ON” selects fluorescent dimming curve. “OFF” selects
linear (standard) curve.
S7 STATUS OUTPUT ENABLE
When “ON” will maintain the last active levels for 5 min.

S8 CONTACT CLOSURE POLARITY
Sets the polarity of the contact closure input. “ON” se-
lects normally open, “OFF” selects normally closed.

Two LEDs are used to indicate processor/power supply
status and data receive detection.
RUN Glowing steadily indicates power supply and
processor OK; off indicates no power, and flash-
ing indicates defective processor hardware.
RxD Glowing steadily indicates data signal received;
off indicates no signal present. Note that an ad-
dress selection out of the DMX signal range will
turn off the LED.
FL1 - FL4 when illuminated indicate a wiring fault on the
"dimmed hot" line(s). The indicated output(s) should be
disconnected, the fault cleared, and then reconnected.
OP1-OP4 indicate ballast control (drive) level. The LEDs
increase in brightness in proportion to the signal level.
EFBC-4L FLUORESCENT DIMMING BALLAST CONTROLLER

>?D5C
GENERAL
The interface is designed to directly control Lutron Hi-
Lume FDB & ECO series electronic fluorescent dimming
ballasts from industry standard low voltage lighting con-
trol signals. Four separate channels of control are pro-
vided on each interface card. NOTE: When using ECO
series ballasts, all circuits controlled by the same
interface card must be connected to the same phase
as the card power
supply.
INPUTS
Each channel of dimming is capable of individual control
from 0-10VDC (analog) and DMX512 (digital) control
sources. Where both sources of control are connected
and enabled, they will function in a highest level takes
precedence (pile on) mode.
OUTPUTS
Each output consists of a ballast control (dimmed hot)
lead and a ballast power (switched hot) lead. Dimmed
hot outputs are internally fused to protect the interface
card against fault currents and miswiring. Each hot out-
put incorporates a relay contact which opens when the
control signal level falls below the level preselected by
"SW1", shutting off power to the ballast(s).
CAPACITY
Each output is capable of controlling up to an average of
25 120V or 50 277V ballasts per channel, depending on
the ballast type.
MOUNTING
The interface should be mounted on minimum 0.5 inch
high #6-32 standoffs.
