Testing the Configuration
After programming the unit, you must test the device to ensure that it performs to your
specifications. This test can be run in simulation mode or by varying the level in the
application. The latter is preferred as it more accurately represents running conditions.
However, if it is not possible to do a physical test, a simulation will ensure that control
programming is correct.
Simulation
In simulation mode, the LCD display reacts to the simulated level changes. Alarm relays
will also react to the simulation, but any pump or control relays will not react.
To allow pump or control relays to operate on the simulated level, set P000 to –1.
Simulating a Single Measurement
Access the appropriate parameter: (press PROGRAM and then key in the parameter
number). Press TRANSDUCER five times to overcome Echo Lock (P711) if applicable:
the associated Reading is displayed in the Parameter Value field, and any alarm relays
are set accordingly.
To verify Reading calculations (P920 to P926)
1. Key in a material level in Units (P005) or % of Span (P007).
2. Press ENTER to display the calculated Reading.
3. Verify the calculated Reading.
4. To start a simulation from the level entered, press ARROW or .
Simulating a Level Cycle
Starting a (P920, P921, P922, or P923) simulation when level = 0:
1. Press ENTER to simulate level rise and fall. At the start of a simulation, the
default rate is 1% of Span / second.
2. Press the ARROW or to adjust the simulated rate of rise or fall. The
maximum rate is 4% of Span / second.
