1-2 S8M Operations and Operating Modes
The S8M has 3 operating modes: Run Mode, Setting Mode, and Test Mode.
Note When the Support Tool is connected, the S8M can be operated and parame-
ters can be set/changed regardless of the S8M’s operating mode.
Changing the
Operating Mode
The operating mode can be changed from the Mode Selection Menu using
the Up and Down Keys.
Turning the Power ON for
the First Time
• A newly purchased S8M will automatically enter Setting Mode when it is
turned ON for the first time. Refer to SECTION 4 Parameter Settings for
details on setting parameters in Setting Mode.
• When starting operation or setting branch output connections after setting
the parameters, return to the Mode Selection Menu and switch to Test
Mode. Refer to SECTION 5 Trial Operation to Actual Operation for details
on the operations in Test Mode.
• When changing to Run Mode after completing the trial run, return to the
Mode Selection Menu and switch to Run Mode. If the power is turned
OFF while the S8M is in Test Mode, the S8M will enter Test Mode again
the next time that the power is turned ON. In this case, all branch outputs
will be OFF (not connected).
Run Mode Branch outputs are connected while monitoring the input volt-
age, current, internal temperature, and run time. The moni-
tored PV is displayed on the seven-segment display and can
be read with key operations.
Setting Mode This mode is used to set parameters. Branch output connec-
tions are the same as in Run Mode. The S8M automatically
starts in Setting Mode when the S8M is used for the first time.
Test Mode This mode is used to test operation. The factory default set-
ting for all outputs is OFF, so the branch outputs being used
must be turned ON in Test Mode.
