Siemens 200 instruction manual Checkout, Application Test

5.Change parameters P610 and P611, as required.

6.Repeat steps 2 to 5 until the flow curve is verified.

I/O Checkout

After the unit is installed, test to verify the wiring.

Relays

Use P119 to force a state change and verify that the results are as expected (pump starts, alarm sounds, etc.).

Discrete Inputs

Use P270 to force the input value and verify that the results are as expected.

1.Go to P270 [DI] where DI = the discrete input to be tested

2.Set P270 to 0 (forced OFF)

3.Go to P275 [DI] to verify that the value is forced

4.Check the state of outputs to ensure that they respond as expected

5.Go to P270 [DI]

6.Set P270 to 1 (forced ON)

7.Go to P275 [DI] to verify that the value is forced

8.Check the state of outputs to ensure that they respond as expected

For further information see Discrete Inputs section on page 48.

mA Input [MR 200]

Use P254 to test the mA input value against a true level. Use a trusted external mA source to generate the signal required for testing, and verify the incoming signal with P260. Check that the system responds as expected when the mA level is changed.

mA Output

Use an external device to test the mA output against the measured level. Check that the mA value changes to reflect the changes in the measured level.

Application Test

If you are testing the application by varying the material level (the preferred test method) make sure that none of the control devices is connected (or at least that no power is available to them).

If you are testing the application in simulation mode (and P000 is not –1), then control relays are not energized and the control devices can remain connected.

While the level is being cycled, check the results of the discrete inputs either by closing the circuit externally (preferred) or by using P270 Discrete Input Function to force the input ON or OFF. Try all possible combinations to thoroughly test the setup. For each combination, run a complete cycle to verify that the relays operate as expected.
