Overview of Features and Functions Section 1-1
Monitoring Temperature
Rise (TMP Output)
The S8M has a built-in temperature sensor and the Over-temperature Output
(TMP) will be turned OFF when the internal temperature exceeds the set
value. This output can also be used to start a cooling fan or air conditioner to
reduce the temperature in the control panel. (For details, refer to 2-4-3 Over-
temperature Output.)
Monitoring the Run Time A Run Time Value can be set and used for periodic maintenance of the equip-
ment. The default setting is 0.0 kh, which disables the alarm output. (For
details, refer to 2-4-4 Run Time Alarm.)
Protecting Parameter
Settings
The Protection Level can be set to restrict access to the parameters. Three
levels, levels 0, 1, and 2, are available. This function can be used to prevent
parameters from being changed or deleted inadvertently. (For details, refer to
4-4 Changing the Protection Level.)
The default setting is protection level 1.
Support Tool
Available
S8M Support Tool is available and can be connected to the S8M-CP04-R and
S8M-CP04-RS. The Support Tool simplifies system startup and maintenance
because it allows the user to set the various parameters, monitor operation,
save settings data, and copy parameters to other S8M Multicircuit Protectors.
The Support Tool can be downloaded from OMRON's home page free of
charge. (For details on the Support Tool, refer to SECTION 6 Support Tool.)
Protection level 0 There are no restrictions on reading and changing the param-
eter settings.
Protection level 1 Permits only reading and changing of the input voltage, cur-
rent, internal temperature, and run time parameters.
Protection level 2 Permits only reading of the input voltage, current, internal
temperature, and run time parameters.
