Operator Menu Advanced Information
The operator menu can change significantly based on a user’s settings.
The two text boxes describe the on-time and the intensity settings. The on time
describes how long the UV LED will be lit after pressing the Start button. The
second textbox reads either Current or Intensity, and is used to describe how
much power will be supplied to the LED.
The textbox at the bottom describes the current UV measurement. This will only
appear if the device is in
Intensity Mode
. In intensity mode, the UV output is
maintained using a PID loop. The measured UV output is shown at the bottom of
the screen as a percentage of the maximum output by default. This value can be
shown in watts or watts/cm2 instead based on the user’s settings.
By default, this device operates in Timer Control Mode. In this mode, the output
can be turned on or off by pressing a footswitch or the “Start” button on the
operator menu. The LED stays on for a set amount of time.
The user can instead set the device to External Control Mode. In this mode, the
operator menu is modified, as shown below. Instead of turning on the UV LED for
a set amount of time after a button press, the UV LED stays on as long as the user
is holding down a pedal or a PLC input is received. In this mode, the Start/Stop
button on the touchscreen is removed.
