Mode one: the jog mode, first, selects the mode one switch 351 and rotates to an on position (only the mode one switch 351 is enabled at this time, the other mode switches need to be turned to an off position, otherwise the system will not start if the mode one switch 351 has been selected on the panel 31, then the mode select icon on the touch screen 34 is set to off, or the mode one switch is likewise set to on the touch screen 34). Next, the test start button 361 is continuously pressed, the brake 21 is opened, the test start button 361 is released, and the brake 21 is immediately released, thereby realizing click control. The click mode is used for clicking to open the brake 21 and checking and adjusting the brake shoe clearance in the process of debugging the brake 21.

Meanwhile, the mode three is used for detecting the mechanical feedback switch of the brake, and the type of the switch needs to be set according to the wiring type of the actual mechanical feedback switch. During testing, if it is not desired to detect the mechanical feedback switch, the touch screen 34 may be set to "no detection" to turn off the detection of the mechanical feedback switch of the brake. Second, the mode three switch 353 is selected to be on (only the mode three switch 353 is enabled at this time, the other mode switches need to be turned off, otherwise the system will not be started if the mode three switch 353 has been selected on the panel 31, then the mode select icon on the touch screen 34 is set to off, or the touch screen 34 is likewise set to mode three switch on).

The purpose of this mode is to check, after the adjustment is basically completed, whether the brake 21 opening sound is required to meet the requirements, whether the mechanical feedback switch of the brake is installed in place, whether the action is reliable, and the like.
Mode four: the reliability test mode first sets the number of operations (in tens of thousands) through the touch screen 34, for example, 200 tens of thousands, and also needs to set the type of switch according to the actual mechanical feedback switch wiring type. During testing, if it is not desired to detect the mechanical feedback switch, the touch screen 34 may be set to "no detection" to turn off the detection of the mechanical feedback switch of the brake. Second, the mode four switch 354 is selected to be on (only the mode four switch 354 is enabled at this time, the other mode switches need to be turned off, otherwise the system will not be started if the mode four switch 354 has been selected on the panel 31, then the mode select icon on the touch screen 34 is set to off, or the touch screen 34 is likewise set to mode four switch to on). Finally, the test start button 361 is pressed, the brake 21 is automatically opened and closed in a cycle of a predetermined period (2 seconds for opening and 3 seconds for releasing), feedback of the state of the brake 21 is made by a feedback switch provided in the brake 21, and the system records the number of tests.
If a fault occurs in the testing process of the four modes, the system stops running, and meanwhile, the corresponding fault indicator 372 is reminded in a flashing and lighting mode at intervals of 1 second, and the system records the times of the fault.
When the test faults and the test times need to be reset during the test, all the four mode selection switches are placed in the gear, at the moment, the test reset button 362 is pressed again for more than 3 seconds, and the fault times and the test times are automatically cleared, so that the next test can be performed.
