Important Notes about Using an External 24V dc Power Supply
ATTENTION
!
Before setting the jumper, all system power must be
turned off. This includes the rack power as well as
any external 24V dc power supply.
IMPORTANT
If the module is configured to use an external 24V dc
power supply, the supply must be turned on for the
module to operate. If the external 24V dc power
supply is turned off, the module’s outputs will be
turned off, and the module’s processor will be reset
until power is restored.
The module’s LEDs will flash the 24V Power Fail
blink code. See the error blink code descriptions in
Chapter 6 for more information.
IMPORTANT
Do not use the 24V dc user power terminal on the
chassis power supply to power the analog output
module.
