SYSTEM OPERATION (CONTINUED)
6
S6
Backlight ON/OFF
The LCD display’s backlight can be toggled ON or OFF from this screen by alternate pressing of
the ENTR key.
S7
Interlock ON/OFF
The IntelliRay has a shutter safety interlock signal which is available on the unit’s rear panel
DSUB connector (see Fig. 6). This signal may be used to force the shutter closed when the door
is opened on the optional UV1080 Rayven Oven, or it may be used in a similar fashion with
customer designed enclosures, fixtures or machinery. The interlock signal can be toggled ON or
OFF from this Setup Menu screen by alternate pressing of the ENTR key. When the interlock
signal is ON and the signal is activated (signal has open connection), the shutter will close if it is
open, and the unit will ignore any command to open the shutter. During this condition, the front
panel Standby light will flash to signal the operator that an interlock opening has occurred, and
the current timer count will be held on the LCD display. Once the interlock is closed, timing from
the last exposure value can be continued by pressing the ENTR key, or cleared to the
previously set starting value by pressing the MENU key.
S8
Temperature Units, Degrees F/C
This menu item will allow the user to select whether the Lamp head and Oven temperatures will
be displayed in units of degrees Fahrenheit or Celsius. At the Temp Unit selection screen, the
timer units can be alternately toggled by pressing the ENTR key.
S9
Oven Over-Temperature Alarm Setting
The value set in this menu item will determine the temperature in the curing chamber at which
an alarm will be triggered to warn the operator that temperature has risen to an unacceptable
level. The alarm will also reduce lamp power to its minimum level to prevent further heating. The
over-temperature setting is adjustable because some applications are more sensitive than
others with respect to chamber temperature rise. Possible reasons for elevated temperature
may be high system room ambient temperature, obstructed cooling air inlets or outlets, or
blocked rear panel air filter. Note that if the IntelliRay is not connected to an oven temperature
sensor (such as is present in the Rayven curing chamber), then an over-temperature alarm
setting equal to zero Celsius (32 Fahrenheit) can be entered to disable this alarm.
S10
Exposure Timer Units, Seconds/Hours
Most curing applications require short exposure times that are best displayed in seconds.
However, some conveyor curing and artificial aging applications require long exposures which
are best displayed with timer units in hours. This menu item will allow the user to select whether
the exposure time will be entered and displayed in units of seconds or hours. At the Timer Unit
selection screen, the timer units can be alternately toggled by pressing the ENTR key.
