LED
V
OK
Green LED on when voltage is in tolerance on BAT+ and BAT–.
V
OFF
Fault – Red LED on when the AUX
SW
+ output are disabled by the CPU control line.
V
OVER
Fault – Red LED on when AUX
SW
+ is disabled due to excess voltage on BAT+.
TEMP
Fault – Red LED on when AUX
SW
+ output are disabled due to the excess temperature of the Power
Input module.
3.2 Input/Output Modules
The I/O modules typically consist of a terminal block for field wiring
and connectors to the backplane. The DL8000 supports up to nine I/O
modules, and can accommodate a wide range of process inputs and
outputs. Each I/O module electrically connects to field wiring by a
removable terminal block. Refer to Figures 3-2 and 3-3.
