Curtis Model 3401T – August 2022 Return to TOC
pg. 30
e programmable parameters allow you to congure the 3401T so that it meets your application’s
requirements. Curtis programming devices provide a user-friendly way to read and write to
the parameters. You can also use the 3401T to read and write to parameters; see View and Edit
Parameters.
Restart the device aer you change a parameter marked as [PCF]. If the device is not restarted, a
Parameter Change fault will occur.
e parameters are grouped into menus. is chapter describes the main menu and the menus
contained by the Program menu, and the Monitor Parameters chapter describes the menus contained
by the Monitor menu.
e following columns in the parameter description tables contain multiple types of information:
• Parameter and CAN Index: e parameter name, followed by the CAN index and sub-index.
is column also identies parameters marked as [PCF].
Note: CAN indexes and sub-indexes are delimited by colons. For example, a parameter with
an index of 0x640F and a sub-index of 0x00 would be represented as 0x640F:00.
• Values and Raw Values: e allowed values as displayed in Curtis programming devices,
followed by allowed values in raw units suitable for CAN messages.
• Access Level and Default Value. e parameter’s access level for Curtis programming devices,
followed by the default value.
Note: Table 2-2 describes how the Curtis programming device access levels correspond to the
3401T access levels.
Most of the parameters described in this chapter are read-write. If a parameter is read-only, the last
line of the Description column will consist of “RO”.
