In this video workshop we're going to take a closer look at the groov EPIC I/O
00:09
module status LED. The status LED is located here at the top of the module
00:15
just below the touch-sensitive groov logo. There are five colors and one blink
00:20
code combination for the LED.Off, red blue, flashing blue, violet, and yellow.
00:29
Let's take a look at each of these and look more closely at each color code.
00:35
When you first power up your groov EPIC if one or more status LEDs are not on
00:41
check that the module is seated correctly and that the front retaining
00:46
screw is correctly installed. At first power up the status LEDs will be red as
00:53
a process of boots up and starts communicating with each module. This is
00:58
normal initialization behavior. The status LED will turn solid blue once it
01:04
communicating with the groov EPIC PR1 processor. If you touch and hold for two
01:11
seconds the touch-sensitive cap on a module and thereby select it, it's blue
01:16
status LED will start flashing on and off. This way you know exactly which
01:21
module you are inspecting in groov Manage on the front touch screen of the
01:25
processor. When you do a module firmware update the status LED will turn a violet
01:34
color for the duration of the update. It will in turn red briefly and then back
01:39
to solid blue as it starts communicating with the processor after the update.
01:44
Lastly the yellow status LED color indicates a quality error. This color
01:50
will show if you have one or more channels with an open-circuit or bad
01:53
transducer for example a blown fuse or a bad temperature sensor. For more
