Installation and Use
Revised February-2016
The CPU contains a microprocessor supervisory circuit. This device
monitors the battery voltage, resets the processor, and disables the
SRAM chip if the voltage goes out of tolerance. The CPU has an
internal Analog to Digital Converter (A/D). The A/D monitors the
supply voltage and board temperature. The CPU has two buttons (see
Figure 2-7
):
LED
– Press to turn on the LEDs on the CPU module, I/O modules,
and communication modules when the DL8000 has timed out.
RESET
– Press to reset the DL8000 system to defaults.

As a power-saving feature, you can enable or disable the LEDs on the
DL8000 (with the exception of the LED on the power module). You can
also use the ROCLINK
™
800 software to configure how long the LEDs
remains on after the LED button on the CPU module is pressed. For
instance, with the default setting of five minutes, all LEDs go off after
five minutes. If you press the LED button, LEDs become active again
for five minutes. If you enter a 0 (zero) setting, they always stay active.

Installing and Removing Wire Channel Covers
The DL8000 includes wire channel covers (see
Figure 2-5
) you install
over the wiring channels once you complete wiring the terminal blocks
on the modules.
To install a wire channel cover:
1.
Align the wire channel cover over the wire channel, allowing
unobstructed wire access.
2.
Press the wire channel cover into place until it snaps.
Note
:
The tabs on the top side of the wire channel cover should rest in
the slots on the top edge of the channel.
To remove a wire channel cover:
1.
Grasp the wire channel cover at both the left and right ends.
