7.2 Logic Signal Descriptions
The
Lamp Ready/Shutter Open signal
is a dual function status output from the curing system.
During the warm-up period, the signal remains in a high (no conduction) state, and will drop low
to signal the warm-up interval is complete. Once the shutter is commanded to open (either by
the keypad or external interface connector signal), the Lamp Ready/Shutter Open signal will
again return to a high (no conduction state) as soon as the shutter has reached its fully open
position. When the shutter is commanded to shut, the signal will drop back low again once the
shutter has reached its fully closed position. The toggling of this signal with shutter position
allows an external PLC or controller to confirm the shutter has reached its newly commanded
position.
The
Shutter Command Input
can be used to externally control exposure time of the curing
system. When controlling the shutter from the shutter command input, the exposure timer
should first be set to manual by entering a value of zero at the front panel keypad (refer to
Exposure Time in section 6.5). This setting will only have to be made once, since it will be
stored in non-volatile memory and recalled after power is cycled. When the shutter input is
