Offset
This is the starting point, the Process Variable value at which you get 4 milliamps if the output is set up as
4-20mA (or 0 milliamps if output is set up as 0-20mA). Clicking on this value will display an input box from
which the user can select a new value. The range is –32768 to 32767.
Range
This is a Process Variable value between 4 and 20 milliamps (or 0 and 20 milliamps, depending on setup). .
Clicking on this value will display an input box from which the user can select a new value. The range is –
32768 to 32767.
Note - The range, although not displayed with a decimal point, contains a decimal point that is dependent
on the process variable selected. For example, if the offset is 20 mV for 4 mA, and you want 100 mV to be 20
mA, then your range should be 80. If the process variable is temperature, then the range will be 80, since
temperature PVs do not have a decimal. If the PV is % Carbon, then the range will need to include the two
decimal points for % Carbon. So, a range of 80 will be entered as 8000. See below for more examples .
Current Selection
Provides the option of 4-20 mA or 0-20 mA control. Clicking on this value will display an input box with a
drop-down list from which the user can select either of the two values listed above.
Offset and Range when assigned to a control loop
Inc : 0 = 4mA, 100 = 20mA
Dec : 0 = 4mA, -100 = 20mA
Example: if 4 – 20 mA = 800 mV - 1200 mV
Offset = 800 (starting point)
Range = 400
Passcode and Alarm
There are three levels of menus in the 9205
controller - Operator, Supervisor, and
Administrator
Operator Level
These are functions typically handled by a furnace
operator and do not require a passcode. When an
operator is logged in, the lock on the toolbar will be
blue - .
Supervisor Level
These are functions typically used by a supervisor
and require a level 1 passcode. When a supervisor
is logged in, the lock on the toolbar will be gold -
. To change the level 1 passcode, or the web level 1 passcode, click on the “Level 1 Code” value (range is –
32768 to 32767) or the “Web Level 1 Code” value (range is 0 to 9999) and an input box will be displayed
where the user can select a new value.
Administrator
These are functions typically used by an administrator and require a level 2 passcode. When an
administrator is logged in, the lock on the toolbar will be green - . To change the level 2 passcode or the
web level 2 passcode, click on the “Level 2 Code” value (range is –32768 to 32767) or the “Web Level 2
Code” value (range is 0 to 9999) and an input box will be displayed where the user can select a new value.
