For 17.7 and 17.8 during the tests have been done manual operation to subtract the number of operating cycles in both trials made in week
If the test procedure from 17.10 to 17.13 in the use of the clutch, it should not start too fast due to the errors. If this
Mistakes or considered easy to mistake the starting speed should be standard. Stop time should be calculated in the cycle, in order to release the normal use
Heat generated.
Addition of provisions. only timer, the end of each cycle to be an appropriate start to begin the next cycle.
If the timer or the timer switch has a different program, you should select the maximum number of cycles Contact operation procedures, unless the manufacturer provides a special
Test Procedure.
If the program does not lead to any action contacts should use different test procedure was repeated on a new sample group or several groups to determine
Ensure that all contacts can be subjected to the test. When the timer is designed so that it can be reasonably predicted from the test results of the first set of samples of these additional test
Sample test results, these samples do not have to carry out additional tests, such as contacts at all the same situation can be done reasonably predicted.
If you are using a dedicated test program timers test should be designed to ensure that by performing this specific test procedures can reasonably
All test results predict timer prescribed procedure.
Belt line, vertical-mounted and stand-alone controller, the test shall be as follows.
