Energizing Power Supply System Components
Note
If turned off, the Model 430 Programmer must remain unpowered
for at least 5 seconds before it is powered back on. If not, there may
be an initialization error, in which case the following screen will be
displayed.
If this occurs, turn the Model 430 Programmer off, wait 15 seconds
or more, and power the Model 430 Programmer back on.
When powering the system off, first turn off the power supply controlled by
the Model 430 Programmer followed by the Model 430 Programmer. The
controller will then ensure the load sees no abnormal power transients as
the power supply is turning off.
