PP600F/602F LED lighting controllers - User Manual
9.3.4
Current protection
Current protection can be used to provide the LED from being overdriven.
This is not absolute protection but provides some safety when setting up
the PP600F.
Use Extended Set-Up to set the maximum current rating for each output
channel. The PP600F will then ensure that the current to the LEDs,
averaged over approximately 200ms, does not exceed the rating.
If the rating is exceeded, the output is turned off and the display shows
EC 1
or
EC 2
to show which channel has exceeded its rating. If one of
these messages is displayed press the
SELECT
button to clear it.
Note that after a cold boot (and the factory default) the maximum rating is
set to 4A.
9.3.5
Setting numeric values
When the PP600F displays numeric values for the user to change, the right
hand digit flashes to indicate that the
p
and
q
buttons can be used to
change the lowest digit. Pressing the
RANGE
button selects another digit
which flashes, indicating that it can be changed by pressing the
p
or
q
buttons.

Simple Set-Up
Use Simple Set-Up to set continuous output and pulsed output.
9.4.1

Set-Up. Set up continuous mode as follows:

Pressing and holding
SELECT
at any time will cancel the operation.
Do not set the output current higher than the rating for the LEDs.
The PP600F is ready. Press and hold
SELECT
for one second.
Use the
p
and
q
buttons to select which output
channel to set up -
CH1
or

. Press
