Observe or measure the displacement of the driven member 30.Using the realization method, be conducive to testing staff's comprehensive function power size, position
Shifting amount, the force threshold of setting and displacement threshold value (can be occurrence can also be value range), foreign matter protective device
Action state, determines whether foreign matter protective device can work normally.For example, if displacement reaches threshold value and foreign matter protection dress
It puts and does not trigger staircase protection act or displacement is not up to threshold value and foreign matter protective device triggering staircase protection act or displacement
Amount reach threshold value and foreign matter protective device triggered as normal staircase protection act but foreign matter protective device can not normal reset (foreign matter is protected
Whether normal reset can be based on whether displacement detecting mechanism observation driven member 30 after driving force is laid down returns to just to protection unit
Beginning position confirms that the initial position refers to position when driven member 30 just contacts under driving force effect with fishback), then
Determine foreign matter protective device exception；If displacement reaches threshold value and foreign matter protective device triggering staircase protection act, it is determined that
Foreign matter protective device is normal.
