1-2 S8AS Operating Modes

Operating Mode

Keys simultaneously for 3 s. The Mode Selection Menu will be displayed. Use
the Up (SEL) Key to select the desired operating mode and then press the

Note (1) The Protection Level function can restrict parameter read/write access to
one of three levels. For details, refer to 4-3 Changing the Protection Level .
(2) The Initialize Parameters function restores all of the S8AS's parameter
settings to their default values. For details on default values, refer to 4-1
Parameter Table .
(3) Test Mode can be entered only in protection level 0 or 1.
(4) The Setting Mode, Protection Level, or Parameter Initialization options
cannot be accessed with models such as S8AS-24006N/48008N that do
not permit changes in parameter settings.
Run Mode The output voltage, output current, internal temperature, and
run time are monitored while supplying 24 VDC to the branch
outputs. The monitored values can be displayed on the seven-
segment display.
The S8AS automatically starts in Run Mode when the S8AS is
used for the first time.
Setting Mode This mode is used to set parameters. Branch output connec-
tions are the same as in Run Mode.
Test Mode
(See note.) This mode is used to test operation. The factory default setting
for all outputs is ON, so any branch outputs that are not being
used must be turned OFF in Test Mode.
