FL-4020 FLUORESCENT BALLAST CONTROLLER

Version 1.0 OWNERS MANUAL 10/06/2005

PRODUCT DESCRIPTION

The FL-4020 is a four channel controller add on product for the AR-1202 Architectural dimmer. It provides control
of dimmable fluorescent lighting ballasts. The FL-4020 provides four 2400 Watt channels of fluorescent dimming
which is interfaced to the AR-1202 control circuitry. The AR-1202 uses its four auxillary channels (13 – 16 ) to
control the FL-4020. Dual SCR “zero crossing” switching is used to control the switched hot lines.

The FL-4020 is supplied in two versions:
FL-4020A: Controls ballasts which use a switched 120 VAC “hot” and a dimmed 120 VAC as a control signal.
FL-4020D: Controls ballasts which use a switched 120 VAC “hot” and a 0-10 VDC dimming control signal.

INSTALLATION

MAKE CERTAIN POWER IS REMOVED FROM THE FEED CIRCUITS

BEFORE YOU BEGIN INSTALLATION.

The unit should be wall mounted close to an AR-1202 dimmer. The unit may be "stood off" from the wall (aprox.
1") to assure clear airflow across the rear heat sink surface. A 120VAC 20 Amp power input must be provided for
each dimming channel. Each channel may control multiple ballasts as long as the channel load does not exceed
2400 Watts. The internal low current electronic circuitry is powered, via a 1/2 Amp 250VAC fast blow fuse, by the
H1 input power connection.

REQUIREMENTS FOR THREE PHASE OPERATION:
In order to provide zero crossing switching, the AR-1202 uses a specific phase sequen ce when operated with 3
phase power. The sequence convention must also be adhered to when connecting the FL-4020. The phase

connected to the AR-1202 H1 power input terminal must also be used for channels 1 and 4 of the FL-4020. The
AR-1202 H2 phase must be used for FL-4020 channel 2. The AR-1202 H3 phase must be used for FL-4020
channel 3. The table below summarizes this requirement.

OWNER MAINTENANCE

There is a 1/2 Amp., 250 Volt, fast acting fuse in the unit to protect the internal electronic circuits from an
overvoltage condition. The fuse may be replaced ONLY by a fuse of the same size and type.

The best way to prolong the life of your unit is to keep is cool, clean, and dry. It is important that the cooling
intake and exit vent holes are clean and unobstructed.

Service by other than Lightronics authorized agents may void your warranty.
