18.13Measuringthetimedelay^T0

The time measurements between any parts of the machine cycle can now be obtained,

from the Trace waveforms.

The following procedure describes how the 5-sec time delay of T0, can be checked

from the Trace waveforms.

1. The 5-sec delay of T0 is controlled as follows:

(a) It starts with the closure of X2, i.e. when piston A returns to its A position.

(b) On timing out, output Y1 turns OFF.

2. Using the left-hand mouse button, double click on the rising edge of X2

(seeFigure18.15).

3. Note that timer T0 has
