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. Go to the parameter to be simulated (P920, P921, P922, P923, P924, P925, or P926),
and key in a material level in Units (Units defined in P005), or % of Span (% of Span
defined in P007).
2. Press ENTER to display the calculated Reading. [Regardless of setting for P001,
the parameter value being simulated will display as the primary reading. The
auxiliary reading will always display the level value (P921). See “Display” on page 21
for positions of the primary and auxiliary readings on the LCD.]
3. Verify the calculated Reading. (At this point, the simulation is in Stop state. The
effect of the ARROW key is based on this state. See chart on page 84.)
Simulating a Level Cycle
Starting a (P920, P921, P922, or P923) simulation when level = 0:
1. Go to the parameter to be simulated (P920, P921, P922, or P923).
2. Press ENTER to simulate level rise and fall. At the start of a simulation, the
default rate is 1% of Span / second.
Note:
When you set P001 = 3 (Distance), span (P007) is preset to empty (P006),
therefore the primary and auxiliary readings may display the same value when
Space (P922) is being simulated.
