Test job control mode: PLC
“.
3. Test job or speed measurement (is started by key operation and automatically terminated).
By pressing the button the SND40 outputs the signals to the PLC. The staus message “Waiting for PLC start” is
generated by the SND40. The PLC prepares a tube for detection and gives the signal “start test job” to the SND40.

t1: < 100 ms
t2: Time which the PLC needs to prepare a tube for parameter programming (Putting-on the tube).
t3: < 30 ms
t4: Duration of test procedure / locating of rotation rate is according to tube diameter and tube rotation rate.
t5:
≥
0 ms
t6: At the end of the test procedure / locating of rotation rate the Start signal must be cancelled.
t7: > 30 ms
The duration of parameter optimization (test job / locating of rotation rate) depends on tube diameter, tube rotation rate and
the time required for entering the parameters.
Test job:
Transient time + 3 to 4 tube turns
Speed measurement
approx. 60 s transient time + 5 tube turns
