11 What Happens If …?
If a easy800 does not behave as expected, the following tips can help you in
rectifying any possible problems. If a program does not function as expected,
in spite of a thorough simulation in easySoft-Pro, the power flow display in
the easy800 display enables you to test the logic operations of the circuit
diagram.
Only qualified persons should test electrical voltages while the easy800 is in
operation.
