1. ZD-715 seat belt overall dynamic load, static load testing machine
1. Non-professional maintenance personnel shall not open the cover and disassemble and change the internal electrical components of the instrument.
2. In case of emergency, please press the emergency stop button quickly and cut off the main power supply. After the fault is removed, turn it on again.
3. The power supply of the instrument is a single-phase AC power supply, and there must be a reliable grounding wire.
4. When the instrument is not used for a long time or encounters rain or snow, you need to remove the dynamic sensor. The removal step is: the person must climb to the corresponding height while wearing the seat belt, remove the plastic parts, remove the sensor with a wrench, and remove the corresponding connecting wires.
5. When the instrument is not used for a long time or encounters rain or snow weather, it is necessary to properly protect the instrument components. For example, the box with the motor is covered with a tarpaulin to prevent rainwater from entering the inside of the box along the top hole, causing damage to the motor. The controller of the electric lifting device needs to be wrapped with a tarpaulin to prevent rainwater from entering and the like.
6. The function of the flat sling in the accessory is the secondary protection of the seat belt. When the test belt is unqualified, the flat sling can only be subjected to three impacts. When testing again, the flat sling must be replaced.
7. During all test procedures, as long as the simulated person leaves the bottom surface, the tester must stay away from the shelf for more than 3 m, whether during lifting or release. Prevent accidental injuries caused by falling objects. One minute after the completion of the test, the person can enter the internal position of the frame to handle the follow-up.
9. In the static load test, because the test force value is relatively large, in order to prevent the personal injury caused by the tester when the sample breaks, the safety protection net is hung on the side of the shelf where the tester operates.
10. Be sure to equip the UPS uninterruptible power supply that matches the instrument (otherwise, in the unstable power supply state, the simulated person has the danger of falling!), in the event of an emergency power outage, quickly turn the selector switch to “keep the pull-in†Status, then turn off the instrument. When the power supply is normal, lower the simulator, then turn the selector switch to the "test state" and restart the test.
Second, ZD-717 seat belt overall slip tester
1. The instrument must be fixed with anchor bolts.
2. The column must be fixed during the test.
3. Adjust the flap during the test so that the column is located in the groove of the flap.
Third, seat belt tension machine
1. The instrument has two display windows. The first window displays the sensor force value in N; the second window displays the countdown time in seconds.
2. Before starting the test, please warm up for 15 minutes.
3. Please keep your head and hands close to the chuck and moving parts when the instrument is running to avoid injury.
4. Non-professional maintenance personnel shall not open the cover and disassemble and change the internal electrical components of the instrument.
5. In case of emergency, please press the emergency stop button quickly and cut off the main power supply. After the fault is removed, turn it on again.
6. The power supply of the instrument is a single-phase AC power supply, and there must be a reliable grounding wire.
7. The dynamic test part of the instrument is equipped with upper (lower) limit stroke protection. When the loading device runs to the upper (lower) limit position, it plays a protective role. At this time, you need to press "reset" ("start") or pass "Dropping" ("Dropping") drops (rises) the loading device a distance.
8. The “Reset†button on the operation panel can only be used after the end of one test, that is, the indicator light flashes and the beep is 10s, and the “clear†button should be used to stop the test.

RJ45 interface can be used to connect RJ-45 connectors. It is suitable for the network constructed by twisted pair. This port is the most common port, which is generally provided by Ethernet hub. The number of hubs we usually talk about is the number of RJ-45 ports.
RJ45 is a type of different connectors (for example: RJ11 is also a type of connector, but it is used on the telephone); there are two different ways to arrange the RJ-45 connector: one is white orange, orange, white green, blue, white blue, green, white brown, brown; the other is white green, green, white orange, blue, white blue, orange, white brown, brown; therefore, there are also wires with RJ45 connector There are two kinds: straight line and interleaved line.
The RJ-45 port of the hub can be directly connected to terminal devices such as computers and network printers, and can also be connected with other hub equipment and routers such as switches and hubs. It should be noted that when connecting to different devices, the jumper method of twisted pair cable used is different.
