Digital Multicircuit Protector S8M 13
■ Run Mode
Run Mode is used for normal operation. When the input power is
turned ON and the mode was Run Mode or Setting Mode the last
time the input power was turned OFF, the S8M will start in Run Mode
and connecting the branch outputs will be started. Monitoring of the
voltages, currents, run time, and temperature can be confirmed using
the Up Key and Down Key ( and ).
Note: 1. The S8M will start in Setting 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.
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.
When switching to Run Mode from Test Mode, first turn ON
all of the branch outputs.
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.
Status Indicators
The status indicators light according to the branch output status as
described below.
Clearing the Peak Output Currents
The peak output currents can be cleared. Select the peak output
current to be cleared in Run Mode and then use the following
