Setting Functions
Refer to SECTION 4 Parameter Settings for details on parameter settings.
(These parameters cannot be changed for the S8AS-24006N/48008N.)
Branch output
peak current Displays individual branch
output peak currents. 0.0 to 20.0 Lit A
(flashing)
Replacement
time Displays the estimated num-
ber of years left until the
S8AS needs to be replaced.
(Setting: 0.0 to 5.0 years, in
0.5-year increments.) FUL, HLF
0.0 to 5.0
Not lit Yrs
Internal tempera-
ture Displays the S8AS's inter-
nal temperature.

range
Undervoltage
detection thresh-
old The undervoltage detection output (LOW) is output
when the output voltage of the S8AS falls below this
detection threshold. The detection threshold can be
set in 0.1-V increments. Branch outputs will not be
cut off. 18.0 to
26.4 V
Abnormal current
tripping threshold The current tripping threshold can be set for each
branch output in 0.1-A increments. 0.5 to
3.8 A
Abnormal current
tripping type The tripping type can be set for each branch output.
USU: Standard (tripping within 100 ms)
INS: Instantaneous (tripping within 20 ms)
LNG: Extended (tripping within 1,000 ms)

Maintenance
forecast monitor
function Set the expected number of years until the S8AS
needs to be replaced. When the estimated value falls
below the set value, the maintenance forecast moni-
tor output (LFE) will turn ON. (The photoswitch output
will turn OFF.) 0.0 to
5.0 yr
Over-tempera-
ture threshold An excessive temperature rise inside the S8AS will
be detected and the over-temperature output (TMP)
will turn ON. (The photoswitch output will turn OFF.)
This output can be used to control cooling equipment
to reduce the temperature in the control panel.

Startup
sequence The connection of branch outputs may be initiated by
communications or when the power is turned ON,
and a time delay can be set for the connection
sequence. Connecting the branch outputs in
sequence instead of simultaneously can reduce the
inrush current and reduce the load on the Power Sup-
ply. 0.0 to
99.9 s
Shutdown
sequence Branch outputs can be disconnected in sequence ini-
tiated by communications or an external tripping input
(TRP), and a time delay can be set for the sequence. 0.0 to
99.9 s
Tripping trigger
input The external tripping input function (TRG) can be
enabled (ON) or disabled (OFF) for each branch out-
put. OFF, ON
Tripping trigger
type The tripping trigger type can be set for all branches
that have the tripping input function enabled. EGE, LVL
