Setting up LED Modules
Each LED module can be individually confi gured. It can be enabled/disabled. You
can set the output current, determine when (in a period) the LED illuminates and
how much of the period that the LED remains lit. You can also see the combined
output of the all enabled LEDs.
1. Press
the
Module Confi g
button to enter the module confi guration menu. The
menu for Module 0 displays. To confi gure a different module, press the
Module
Confi g
button again until the desired module appears. Note two example
confi gurations are shown in the table below

2. Press
the
Setup
button until the arrow displays next to the parameter you wish
to adjust.
•
Current
–Increasing the current boosts the power and the light output of the
LED module. The current can be adjusted in 1mA increments.
•
Delay
–The delay determines how far into a period before the LED module
turns on. In this example, LED module 0 illuminates after a 1% delay time.
•
Width
–The width is the percentage of the period that the LED module
remains lit. In this example, LED module 0 will remain on for 33% of the
period (Fig. 32).
•
Enable
–Enable allows the module to illuminate during a cycle. Disabled
modules will not illuminate. You can also see the enable/disable status of
an LED module on the main parameters display. (See “Parameters Display”
on page 15.)
NOTE
: OUTPUT is a read-only parameter that shows the active output of all enabled
LED modules.
