Please refer to Chapter 2. Turn on the life-cycle tester; do not turn on the load cabinet at this time.

4.1.2 Conectarea compresorului de aer

Connect an air hose with an outer diameter of 8 mm to the endurance testing machine, then turn on the air compressor.

4.1.3 Connecting the Load Cabinet, Endurance Tester, and Specimen

The load cabinet has the following four terminals—two red and two black—as shown in the figure below.

Figura 10

4.1.3.1 Single-Pole Switch

Connect the two red terminals or the two black terminals of the load cabinet to the life tester, and then short-circuit the other two terminals.

The two terminals on the load cabinet are connected to terminals A and B on the life testing machine, and terminals A and C on the life testing machine are connected to the sample switch, as shown in the wiring diagram for workstation 4 of the life testing machine below.

4.1.3.2 Dual-Control Switch

Connect the two terminals on the load panel that are short-circuited directly to one circuit of the double-pole switch, and then connect the other circuit of the double-pole switch as described in section 4.1.3.1.

4.2 Sample Calibration

Open the manual window of the life test machine. Click the button for the corresponding test station to perform a single-cycle operation, then observe the position of the machine’s actuators. If the test specimen is a switch, adjust the machine so that when the upper actuator extends, it just closes the switch, and when the lower actuator extends, it just opens the switch.

After debugging is complete, the switch should be set to the off position.

Figura 12

5. Switch Life Test Procedure

5.1 Configurarea dulapului de încărcare

Turn on the power switch for the load cabinet.

The number of test cycles is factory-set to 9999, and the adhesive holding time is factory-set to 90 seconds. Users can also adjust these settings as needed.

Turn on the load cabinet’s power switch, press the “Start Load Output” button, and turn on all cooling fans.

Slowly rotate the voltage adjustment dial while monitoring the test voltage until the voltage meets the test specifications. Note: When the load voltage exceeds 305 V, the device will automatically disconnect the load.

Turn on the tungsten filament lamp quantity selector switch as needed; with a maximum load of 30 tungsten filament lamps (if switches 1, 2, 3, 4, 10, and 10 are all turned on, the total number of tungsten filament lamps in use is 1 + 2 + 3 + 4 + 10 + 10 = 30). Users may also freely combine switches according to their needs.

Example: According to Clause 18.3 of standard GB/T 16915.1-2024 (IEC 60669-1:2017, Clause 18.3), when testing a 10 A, 250 V switch, the voltage required for a 200 W tungsten filament lamp is 240 V, and 15 such lamps are required.

In the manual window of the life test machine, turn on the switch for the corresponding workstation. See the figure below:

Figura 13

After the switch is turned on, the voltage will drop slightly, requiring you to turn the voltage adjustment knob again. At this point, the test load current is 1.2 times the rated current of the sample switch, or approximately 12 A. Note: When the load current exceeds 22 A, the load cabinet will automatically disconnect the load.

Once the adjustment is complete, go to the manual control panel of the endurance tester and return the specimen to its original state by setting the specimen switch to the “OFF” position.

5.2 Setting Up the Life Test Machine

Parameter Settings Interface. For each workstation, configure the total number of tests, load on time, load off time, number of failed current monitoring attempts, and whether to monitor current.

Note 1: The number of faults refers to the number of times the sample was energized but no current was detected (the test will automatically stop once the actual number of faults during the test reaches the set fault limit; this parameter is invalid when current monitoring is disabled);

Note 2: Current monitoring should only be enabled when a load cabinet is connected to that test station for testing.

Monitoring Interface. Used to view the test status and data for the corresponding workstation. Please click the “Reset” button for the corresponding workstation to clear the previous test data before you can begin testing at that workstation.

5.3.2 Monitorizarea testelor

During the test, you can view real-time data on the monitoring screen.

Figura 15

5.3.3 Sfârșitul testului

If the number of test cycles at a life test machine station reaches the set limit, that station will stop the test and automatically place the specimen in the disconnected state. Important note: The load cabinet is still outputting power; please turn off the load output before proceeding.

If the life tester station is equipped with selective current monitoring and the number of failures during the test reaches the preset limit, the life tester will automatically stop the test at that station and automatically disconnect the test specimen. Important Note: The load cabinet will still be in the output state; please turn off the load output before proceeding with any further operations.

If a sample at a test station on the life tester is damaged during testing and remains in the “always on” state, the load cabinet will trigger an alarm after the load has been continuously applied for 90 seconds and will automatically cut off the output. Please press the alarm reset button on the front panel of the load cabinet and manually end the test for the corresponding station on the life tester.
