Depending on the I/O modules you select, the circuit monitor can accept
either voltage or current signals through its analog inputs. See Table 5–1on
page 70 for a list of I/O options. The circuit monitor stores a minimum and a
maximum value for each analog input.
For technical specifications and instructions on installing I/O modules, refer
to the instruction bulletin that ships with the I/O (see Table 1–2onpage3for
a list of these publications). To set up analog inputs, you must first set it up
from the display. From the main menu, select Setup > I/O, then select the
appropriate analog input option. For example, if you are using the
IOX0404
option of the I/O Extender, select IOX-0404. For detailed instructions, see
“SettingUpI/Os” on page 23 in Chapter 3—Operation. Then, in
SMS define
the following values for each analog input:
• Name—a 16-character label used to identify the analog input.
• Units—the units of the monitored analog value (for example, “psi”).
• Scale factor—multiplies the units by this value (such as tenths or
hundreths).
• Report Range Lower Limit—the value the circuit monitor reports when
the input reaches a minimum value. When the input current is below the
lowest valid reading, the circuit monitor reports the lower limit.
• Report Range Upper Limit—the value the circuit monitor reports when
the input reaches the maximum value. When the input current is above
highest valid reading, the circuit monitor reports the upper limit.
