Cooling fans
The cooling fans menu (
PERS
→
FANS
) gives three options:
• When set to
REG
(the default setting), fans are thermostatically regulated. Fan speed is a function of the
amount of heat the fixture produces. If light output is reduced at the lighting desk, fans will run more
slowly, giving reduced noise.
• When set to
FULL
, fans run permanently at full speed.
• When set to
SLNT
(silent), fans operate as slowly as possible in order to minimize noise. Light output is
limited to minimize the need for fan cooling.
Dimming curve
The dimming curve (
DIM
) menu provides four dimming options (see Figure 5):
-
LIN
(linear) – the increase in light intensity appears to be linear as DMX value is increased.
-
SQR
(square law) – light intensity control is finer at low levels and coarser at high levels.
-
ISQR
(inverse square law – light intensity control is coarser at low levels and finer at high levels.
-
SCUR
(S-curve) – light intensity control is finer at low levels and high levels and coarser at medium
levels.
Custom settings
The custom settings function
DFSE
→
CUS1
-
CUS3
allows you to save and recall three sets of fixture
settings. The savable settings are DMX mode, pan/tilt speed, pan/tilt inverse and swap, display, DMX reset,
shortcuts, noise reduction mode and effects speed.
All settings can be returned to factory defaults using the
DFSE
→
FACT
→
LOAD
command.
Readouts
Software version
INFO
→
VERS
displays the currently installed fixture software (firmware) version. The firmware version is
also displayed briefly at startup.
Cooling fan speed
INFO
→
FANS
displays the current head and LED PCB cooling fan speed in rpm.
Hours of use
INFO
→
TIME
→
POHR
provides a resettable (
RSET
) and a non-resettable (
TOTL
) counter for hours of
use (i.e. number of hours with power applied to the fixture). To return the resettable counter to zero, display
it and then press [Up] until the counter reads
0
. The non-resettable counter displays total hours of use since
the fixture was manufactured.
Temperature
INFO
→
MTMP
,
INFO
→
HTMP
and
INFO
→
LTMP
provide temperature readouts for the main PCB in
the base, for the head module and for the LED PCB respectively. In each case,
CURR
displays the current
temperature.
MSR
displays the maximum temperature since the log was reset, and
MR
displays the
maximum temperature recorded since manufacture.
MR
is non-resettable.
