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 : the calculated Reading is displayed.

3. Verify the calculated Reading.

4. To start a simulation from the level entered, press ARROW or .

Simulating a Level Cycle

To start a (P920, P921, P922, or P923) simulation when level = 0:

Press ENTER to simulate level rise and fall. At the start of a simulation, the default

rate is 1% of Span / second. Press the ARROW or to adjust the simulated rate of

rise or fall. The maximum rate is 4% of Span / second.
