S8AS
Run Mode
Run Mode is used for normal operation. When the power is turned ON
and the mode was Run Mode or Setting Mode the last time the input
power was turned OFF, the S8AS will start in Run Mode and
connecting the branch outputs will be started. Monitoring of voltages,
currents, replacement time, and temperature can be confirmed using
the Up Key and Down Key ( / ).
(1) Output Voltage
1 2 3 4 5 6 V A Yrs °C s
(1) When Run Mode is entered, the parameter
that was displayed the last time Run Mode
was used will be displayed.
The voltage output display is shown at the
left as an example.
(2) Total Output
Current
1 2 3 4 5 6 V A Yrs °C s
(2) The total current for all outputs is displayed.

Down (CH) Key.))
(4) Peak Current for
Branch Output 2

(Select the branch output with the
Flashing
Down (CH) Key.))
(5) Replacement
Time
(3) The output current of the last branch output
that was set will be displayed regardless of
the operating mode.
The current output of the branch output 1 is
shown at the left.
The current output of the branch output 2 is
shown by pressing the Down (CH) Key.
*The branch output number set with the Down
(CH) Key is stored in memory even when the
operating mode or parameters are changed.
The branch output displayed when Test Mode is
entered will not necessarily be branch output 1.
(4) Press the Up (SEL) Key to display the peak
current for the branch output displayed in step 2
(e.g., branch output 2). The “A” unit indicator will
flash while the peak current is being displayed.
The peak current can be cleared by performing
the following procedure while the peak current is
being displayed.
1. Press the ENT Key.
2. Change the “NO” display to the “YES”
display using the Up (SEL) Key.
3. Press the ENT Key again.
(5) Displays the estimated number of years
until the replacement time.
1 2 3 4 5 6 V A Yrs °C s
(6) Internal
Temperature
(6) Displays the internal temperature.
1 2 3 4 5 6 V A Yrs °C s
((1) Switches to output voltage display.)
Press the Up (SEL) Key again to return to the
output voltage display and start the display
cycle again.
Note: 1. The S8AS will start in Run Mode when power is turned ON
for the first time after shipping from the factory.
2. Settings cannot be changed in Run Mode. Use Setting
Mode to change settings. (The setting for the S8AS-24006N
and S8AS-48008N can not be changed.)
3. If a startup sequence has been set, connections will be
started according to the set delays.
4. When moving to Run Mode, the branch output ON/OFF
status from before entering Run Mode will be maintained.
After testing branch output operation in Test Mode, always
turn ON the required branch outputs before moving to Run
Mode.
5. The voltage detection function monitors the voltage at the
power input terminals. Measure the voltage at the branch
output terminals to confirm that the output voltage is correct.
