Lamp
The word LAMP can appear on the display in two situations: one is an
error; the other is normal.
•
Normal:
LAMP will be displayed when the fixture attempts to
strike the lamp during fixture reset and homing. This is normal.
•
Not normal:
If the lamp is running, and for some reason—
probably an electrical event—the fixture’s operating code loses
track of the lamp status, the lamp will turn off and the word
“LAMP” will appear in the LED display. Allow the fixture 5 to 10
minutes to cool before trying to turn the lamp on again.
Link Busy
Occurs when the crossloading fixture detects that some other source is
driving data on the link. For crossloads to work properly, you must
remove or bypass all of the following if they are on the same link:
• Serial data distributors
•Optoisolators
• Non-High End Systems fixtures
• Controllers
• AF1000, Emulator or Intellabeam fixtures: Placing all AF1000,
Emulator or Intellabeam fixtures
after
all Technobeam fixtures is a
good way to do this.
After removing the offending device(s) from the data link, attempt the
crossload again.
Link Empty
Occurs when the crossloading fixture fails to find any other
Technobeam fixtures. If there are indeed other fixtures on the link, a
communication failure has occurred.
Possible causes include:
1. A bad data cable between the crossloading fixture and the first fixture
on the data link. Verify cable integrity with cable test equipment or
replace with known good cabling.
2. See “Link Busy” above.
3. One or more fixtures are powered off. Connect all fixtures on the link
to appropriately-rated power outlets and try again.
4. If none of the above solves the problem, the most likely cause is that
an electronics failure has occurred in the data section of one of the
fixtures on the data link. Try powering off one fixture at a time and
attempting the crossload. If you can isolate the crossload problem to
one fixture in particular, remove that fixture from the link and contact
High End Systems Customer Service in one of the ways shown in the
section titled “Contacting High End Systems” on page Intro-4.
