Example: COMMAND V (Reference Table 3)
Case: 4-20mA #1 = flow, 4-20mA #2 = Temperature, Source Out = Pulse, Sink = Alarm
Pressing [V] [ENTER] will display “Output Mode Selected” followed by:
“4-20mA #1 = Flow” “ 4-20mA #2 = Temp” followed by
“Change? (Y/N)”
Press [ENTER] (no change).
The last saved mode will display at this point. i.e.,
“Source: Pulse” “Sink: Pulse” followed by,
“Change? (Y/N)” Select Y [Enter]. The display reads,
“Source: Pulse” “Sink: Pulse” followed by,
“Enter 1 to make the selction #.” Select [ENTER]. The next display reads,
“Source: Pulse” “Sink: Alarm” followed by,
“Enter 2 to make the selction #.” Select 2 and [ENTER]. The next prompt reads,
“PFactor: 1.000” “Change? (Y/N)>” (this factor can be anywhere from 0.001 to 1000 - A
pulse factor of 1.000 will output 1 pulse per unit of
flow.)
If no change, select N and/or [ENTER] to continue.
The next prompt is, “Sample Period”
“Change? (Y/N)>”
(this value may be set from 0.5 to 5 seconds)
If no change, select N and/or [ENTER] to continue.
The next prompt is, “Source state: ” “High to Low” Change to “Low to High?>” (this selection toggles the pulse
signal normally high or normally
low).
[ENTER] to read display.
“Switchpt1”
“0.0000000” the current set point.
“Change? (Y/N)>” enter Y [ENTER] and enter #______ . Set Point Value , i.e. 50 (value is in same units as the flow and
must be within the calibrated range). [ENTER]. The next prompt is,
“Sink state: ”
“High to Low” Change to “Low to High?>”. Set the output signal to be normally “High” or
normally “Low.” Pressing [Y] [ENTER] toggles the current setting. Pressing [ENTER] resumes normal operation.
NOTE: The display comes up to the last setting saved and stays for 2 seconds. If N or [ENTER] is entered, the menu
proceeds to the Pulse out. If Y is entered, the display moves to the selection options and/or asks for confirmation. If you
miss the option, select [Enter] repeatedly to loop around.
