pulled low, the shutter will open, and when the signal returns to a high level (non-conduction
state), the shutter will close. If it is desirable for the external signal to only initiate shutter
opening, with the IntelliRay performing exposure timing, then the exposure time setting can be
set to a non-
zero value at the unit’s front panel keypad. In this case when the signal goes low,
the system will open the shutter for the exposure time interval set at the keypad, and then the
shutter will close automatically.
Timing for the control signals is shown below in fig. 7:
The
Shutter Interlock signal
provide
s a way to interrupt the system’s exposure cycle for cases
where a safety switch on a door or access panel is opened on customer equipment, or when the
IntelliRay is used in conjunction with the optional UV1080 Rayven curing oven. This signal only
becomes active once it is enabled in the Setup Menu (see Interlock ON/OFF menu item
S7
in
section 6.6). In order for the shutter to operate normally while the interlock is set to on, the
interlock signal must be shorted to its respective return signal. If the interlock signal transitions
high (no conduction) state during exposure, the shutter will immediately close, the current timer
count will be held on the LCD display, and the Standby light will flash to signal the user that the
interlock has opened. At new exposure attempts
, “Interlock Active” will be displayed on the LCD.
