Liquid Controls SP3000 - Manual (Page 58)

The command consists of the word SET HARDWARE, followed by the word FLOW, TEMPERATURE, or
PRESSURE, and then by the input characteristics desired. Key input characteristics are 5V, 10V, 4-20mA, 0-
20mA, RTD, and DIGITAL.
Note that RTD may be used only on temperature input, and DIGITAL may be used only on the flow input.
When configuring the flow channel, the (optional) final word is used to indicate the type of meter being used, and
may be either LINEAR or ORIFICE/PITOT, as required. If this qualifier is omitted, the type is not changed.
EXAMPLES:
SET HARDWARE Pressure 10V (CR)
SET HARDWARE Temperature 4mA (CR)
SET HARDWARE Flow Digital (CR)
SET HARDWARE Flow 4-20 Orifice (CR)
SPECIFIC PARAMETERS SET COMMANDS
Function: The SET command can also be used to set miscellaneous parameters in the instrument. With a
SET command, a numerical argument must follow.
USING THE SET COMMAND:
To set one of the instrument’s preset variables, the instrument will parse the phrase following the word SET to find
the specific preset variable to access.
Certain keywords are required to uniquely identify a variable:
FLOW FACTOR OUTPUT
TEMPERATURE ALARM HIGH
PRESSURE LIMIT LOW
SCALE INPUT FILTER
The phrase must be followed by a decimal number of an appropriate value.
Examples of legitimate SET phrases are as follows:
SET K factor to 1.0123
(CR)
SET flow low input scale to 0 (CR)
SET flow hi input scale to 100 (CR)
SET flow low alarm to 0 (CR)
SET flow hi alarm to 1000.0 (CR)
SET low temperature scale input to –10 (CR)
SET hi scale input of temperature to 100 (CR)
SET output digital scaling at 10 (CR)
NOTE: (CR) indicates the ENTER or RETURN key of the terminal.
After each successfully parsed phrase, the instrument will immediately show the variable that has been changed
and the new value to which it has been set.
If a phrase cannot be understood or is ambiguous, the unit will give an error message.
For example:
SET flow temperature to 12 (CR)
