The Dimmer, Switch, GRAFIK
Eye Control Unit or Master
Control has been incorrectly
activated.
Master Control was not
programmed properly.
The Master Control may be out of
RF communication range of the
nearest Repeater.
A noise source (such as a motor
or computer) is interfering with
the RF communications.
Poor power line frequency
regulation (RadioRA
GRAFIK
®
Eye Interface).
No power available to Repeater.
Repeater has faulty power
supply.
Switch Closure Input Interface is
out of RF communication range
of nearest system Repeater.
System is not in ACTIVATE CON-
TROLS mode.
Remedy
Replace light bulb.
Turn FASS on (refer to operation guide
included with the Dimmer or Switch).
Check that breaker is on and not tripped.
Refer to wiring instructions supplied with
unit.
Verify that the Dimmer, Switch or GRAFIK
Eye Control Unit is in range of a Repeater
by placing the system in BEEP mode.
Verify that each control has been activated
correctly by placing the system into FLASH
mode.
Reprogram Master Control.
Verify whether the Master Control is in range
of a Repeater by placing the system in
BEEP mode.
Move the noise source away from the affect-
ed control (or vice versa if the control is a
Tabletop Master). If it is not possible to
move the noise source, move a Repeater
closer to the affected control.
Use a 24VAC transformer to power the
GRAFIK Eye Interface.
Ensure that plug on the rear of the unit is
inserted fully and that the unit is plugged
into a live wall
receptacle.
Swap power supplies with another Repeater
or Master Control and check unit for power.
If the repeater still appears to be inoperable
after verifying that it has power, or all LEDs
on the Repeater remain unlit after verifying it
has power, please call the Lutron
Technical Support Center.
Move the Switch Closure Interface closer to
a System Repeater.
Place system in ACTIVATE CONTROLS
mode.
