11 SHUTTER CONTROLLER
The OPS power supplies enable users to control a shutter that responds to a TTL signal. Users may
control the shutter using a variety of methods.
Manual mode
A front panel button toggles the shutter open or closed.
Timed mode
The shutter open time, close time, and number of cycles are set
by the user.
Dose mode
The dose, close time and number of cycles are set by the user.
External TTL control
The shutter opens or closes based on an external TTL low or
high signal.
External TTL trigger
The shutter begins a preset time or dose routine when triggered
by a TTL signal going from high to low.
Remote switch trigger
Closing or opening a user-supplied switch, such as a foot pedal
or remote push button, controls the shutter.
WARNING
The use of incorrect TTL shutter settings may cause the shutter to open up at an
unexpected time. This may result in injury to persons and/or damage to property.
Take all necessary precautions against UV light exposure until one is certain the
system is behaving as expected.
