Branch output Displays individual branch
peak current output peak currents.
Replacement Displays the estimated num-
time ber of years left until the
S8AS needs to be replaced.
(Setting: 0.0 to 5.0 years, in
0.5-year increments.)
Internal tempera- Displays the S8AS's inter-
ture nal temperature.
Refer to SECTION 4 Parameter Settings for details on parameter settings.
(These parameters cannot be changed for the S8AS-24006N/48008N.)
Data name
Undervoltage The undervoltage detection output (LOW) is output
detection thresh- when the output voltage of the S8AS falls below this
old detection threshold. The detection threshold can be
set in 0.1-V increments. Branch outputs will not be
cut off.
Abnormal current The current tripping threshold can be set for each
tripping threshold branch output in 0.1-A increments.
Abnormal current The tripping type can be set for each branch output.
tripping type
USU: Standard (tripping within 100 ms)
INS: Instantaneous (tripping within 20 ms)
LNG: Extended (tripping within 1,000 ms)
Maintenance Set the expected number of years until the S8AS
forecast monitor needs to be replaced. When the estimated value falls
function below the set value, the maintenance forecast moni-
tor output (LFE) will turn ON. (The photoswitch output
will turn OFF.)
Over-tempera- An excessive temperature rise inside the S8AS will
ture threshold 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 The connection of branch outputs may be initiated by
sequence 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.
Shutdown Branch outputs can be disconnected in sequence ini-
sequence tiated by communications or an external tripping input
(TRP), and a time delay can be set for the sequence.
Tripping trigger The external tripping input function (TRG) can be
input enabled (ON) or disabled (OFF) for each branch out-
put.
Tripping trigger The tripping trigger type can be set for all branches
type that have the tripping input function enabled.
