The
Alarm signal output
can be used to signal an external system, PLC or audible/visible alarm
device if the any IntelliRay fault condition has been detected. The output is an un-isolated open
collector type capable of sinking up to 0.33 amps of current, that will turn off (go high) when a
fault occurs or if the signal connection is broken. The alarm signal can be used in conjunction
with the +24VDC output to activate external loads such as solenoids or relays. The system will
also display an
alarm message on the unit’s LCD display when a fault occurs (refer to Alarm
Troubleshooting in section 9.2).
7.3 Foot Pedal Control
The system’s shutter can also be controlled using an optional foot pedal (Uvitron P/N UV0725),
allowing for hands-
free operation. The foot pedal connects to the IntelliRay’s rear panel DSUB
connector. When the exposure is set to timed mode, a momentary press of the foot pedal will
cause the shutter to open for a duration specified by the exposure time setting. After the
requested time has elapsed, the shutter will automatically close. To prematurely terminate
exposure before the timer has expired, the foot pedal can be pressed a second time, and the
shutter will close.
When the exposure time is set to zero (manual timer mode), the shutter will be held open as
long as the foot pedal is pressed down. As soon as the pedal is released, the shutter will close.
If it is desirable to have manual pedal control of the shutter position without having to
continuously hold down the pedal, the exposure timer can be set to a higher value than what is
desired, and the pedal can be alternately pressed to open and close the shutter.
7.4 Serial Port Control
The system can be controlled remotely via a PC serial port using the optional Microsoft
Windows™ compatible IntelliRay Curing System Control program (Uvitron P/N UV0527). To
connect the curing system to the PC’s serial port, either the RS232 Interface Cable (Uvitron P/N
UV0525) or the RS485 Remote Interface Cable (Uvitron P/N UV0526) may be used. The
IntelliRay software allows for complete monitor and control of all system functions from an easy
to use graphical user interface. The program also allows multiple curing systems to be
networked using the individual addressing capability of the RS485 communications protocol.
(Refer to the IntelliRay Software instruction sheet provided with the program CD for more
information on serial port control.)
The IntelliRay can also be serial port controlled using custom designed application specific
software. Uvitron has documented the IntelliRay serial protocol and command set and will
supply it upon request for customers who would like to write their own software device driver.
