MEASUREMENT PARAMETERS (P920 to P926)
Use these features to verify HYDRO+ programming.
If HYDRO+ operation has not been verified, disable all associated process
control equipment before accessing the following parameters.
Access the parameter desired and press ; repeat 5 times to overcome Echo Lock
(P711), if applicable. The associated Reading is displayed in the Parameter Value
field, and the mA output and "alarm" relays are set accordingly.
"Pump" and "control" relays are held "off" (however the relay display symbols are
active) unless Lock is set for "Simulation Controls" (P000 = -1).
To start a (P920, P921, P922, or P923) simulation (from level = 0)...
to simulate level rise and fall at 1% of Span / second.
Use the and keys to adjust the simulated rate of rise or fall.
Rise at 4% of Span/second
or
Rise at 1% of Span/second
or
STOP
or
Fall at 1% of Span/second
or
Fall at 4% of Span/second
To verify Reading calculations (P920 to P926)...
1. Key in a material level in Units (P005) or % of Span (P007).
2. , calculated Reading is displayed.
3. Verify the calculated Reading.
To start a simulation from the level entered, or .
(Display the % symbol before entering a % value, see PROGRAMMING Keypad).
