Dmx Control - ETC IRIDEON AR500 Owner's Manual

Problem: Fixture Does Not Respond to Control Data
Assuming fixture calibrates but does not respond to console control data:
If the luminaire will not respond to control data:
7091M1005
08/28/00
Note: On the AR500 luminaire, control data could consist of Composer or
DMX protocol. Refer to section 2.2.2.2 Electronics Plate for control
card/electronics plate identification.

DMX Control

1.Check incoming data signal.
a. If a DMX diagnostic device is available, test incoming DMX
signal at junction box.
b. If DMX diagnostic device is not available set luminaire to a
known working DMX address.
Note: A DMX diagnostic device could be another luminaire or a standard
diagnostic indicator.
b. At AC/DMX input cable connector pins 2 and 3, check/test
incoming data signal.
c. If DMX is present at junction box, but not in luminaire, replace
DMX/AC input cable assembly (refer to 6.2.20 Replacing the
DMX/AC Input Cable Assembly).
Note: The following tests assume that a valid DMX signal is present. The red
LED on the lamp control PCB flashes more rapidly when DMX is present.
2.Test lamp control PCB.
a. Check the four green 1/16 amp fuses with an ohm-meter and
replace if necessary (refer to 6.2.31 Replacing Lamp Control
PCB 1/16A, 125V, Pico II Fuse).
b. Retest PCB. If there is still no response, replace lamp control
PCB (refer to 6.2.28 Replacing the Lamp Control PCB).
3.Test DMX address switch assembly and cable.
a. Test again, using thumbwheel address 990. If fixture still does
not respond, replace address switch PCB assembly (refer to
6.2.25 Replacing the Address Switch PCB).
b. Set thumbwheel address to 990. This should run color changer
test routine. If fixture does not respond, replace address switch
cable (refer to 6.2.24 Replacing the Address Switch Cable).
