Lamp Hour Meter Mode
The display can be changed to a resetable hour meter that keeps a memory of total
elapsed lamp hours while ignited. This feature is useful in determining when a lamp should
be replaced. Output and performance will dramatically decrease while the possibility of
lamp failure will increase if the lamp is allowed to operate past its maximum rated life.
All
NOCTURN lamps have a maximum rated life of 1,000 hours peak UV-A intensity
.
The HOUR METER mode will
always
display 4 digits, between “0000” and “6535” (
unlike
the DMX ADDRESS mode that will display an “A” character followed by 3 digits
). The timer
can reach a maximum “6535” hours, and will rollover to “0000” when it is exceeded.
1. Plug the power cord into a power source and push the power switch/ circuit breaker to
the ON position.
2. The display will energize and show the HOUR METER mode. The display will show 4
digits total, “0000” to “6535”. The fixtures should arrive from the factory preset at “0000”
when the HOUR METER mode is active.
3. To reset the HOUR METER to “0000”, depress all three NUMERIC SELECTION BUT-
TONS (triangles) together and hold for approximately 5 seconds or until the display
shows “0000”.
The display (when active) will show a moving decimal point when the HOUR METER mode
is active and the lamp is operating. The decimal point will float across the bottom of the
display from the left to right. This indicates the relay within the fixture is closed and the
lamp is ON.
When the HOUR METER mode reaches 1,000 hours (elapsed lamp life), the display (when
active) will move from a steady state to flashing state. This indicates the lamp has reached
its maximum rated life and should be changed. Follow the instructions for resetting the
timer to have the display reset to a steady state.
