Mode Descriptions
The S8AS supports a Run Mode, Setting Mode, and Test Mode.
Run Mode
Used for normal operation.
The measurements for the output voltage, output
current, replacement time, and internal
temperature can be read on the seven-segment
display.
Setting Mode * Used to set or change S8AS parameters.
Test Mode
Used to test operation for devices connected to
the S8AS.
Note: Refer to the S8AS User's Manual (Cat. No. Z269) for details.
* The S8AS-24006N and S8AS-48008N do not have a Setting Mode.

(1) Run Mode (RUN)
(1) In Run Mode, the current for each branch output, the total output
current, the output voltage, the replacement time, the internal
temperature, and other values can be displayed.
Use this mode for operation once initial settings and system
adjustments have been completed.
(2) Setting Mode (SET)
(2) Setting Mode is used to set parameters.
(3) Test Mode (TST)
(3) Test Mode enables forcing branch outputs ON and OFF.
Connections and cutoffs can be manipulated for all outputs for each
branch output. By default, all outputs will be ON (connected).
Use this mode to set unused branch outputs to OFF (not connected).
(4) Protection Level
(PRT)
(4) Protection Level can be used to set restrictions for setting
parameters.
Three levels, levels 0, 1, and 2, are available. The default is level 1.
Refer to the User's Manual for the parameters that are protected in
each level.
(5) Initialize Parameters

(5) Parameters can be initialized to return all parameters to their default
settings.
The Initialize Parameters is not displayed in the default protection
level (level 1).
((1) Switches to
RUN Mode display.)
Go to Setting Mode to change any of the default parameter settings.
Operation may be restricted by the protection level, preventing
changes to some parameters. If necessary, change the protection
level.
Refer to the User's Manual for details on parameters and restrictions
for the protection levels.
