2. Precautions For The Protection And Use Of The Trial Table Of Common Rail Injector

1) The operator must operate in accordance with the maintenance safety rules of the oil pump repair industry and related diesel electrical control systems. Pay special attention to environmental factors such as the surrounding acid, alkali, gas, high -pressure heavy objects, and items that are prone to sparks to prevent damage to equipment or personal casualties. Then, then

2) It is strictly forbidden to splash water, diesel and other corrosive liquids into the liquid crystal screen and the interior of the test table and the electrical connection site.

3) There are precision electronic instruments inside this test table, please do not fall.

4) When using wire beams and plugs, please try to use screws as much as possible to prevent faults from connecting. If the display is flickering or the blue screen, the program is interrupted or the flower screen, please turn off the power and check the external power after checking.

5) When the fuel tank is not added in the fuel tank, it is strictly forbidden to turn on the total power switch to prevent damage to the dry burning of the heater!

6) The pressure can reach 2800BAR at the highest pressure when detecting the co -sprayer in this test table, so the operation room safety door must be closed during the detection room! Intersection Intersection

7) The front of the operating room is strictly prohibited when the first operating room is runtime to prevent the danger from high -voltage leakage. The first time after the device is running after the tested injector is completed, the operator is not allowed to stand in the operating room in the operating room. front! Intersection Intersection

8) If the problem is not improved, please call the company's technical staff, we will serve you wholeheartedly.

3. About Security

In order to ensure safety operations, please follow the following rules:

1) Use independent special sockets and perform reliable grounding. The power cord of this device is 380V of three -phase and five -line line, please make sure it is reliable;

2) If the power supply voltage is unstable, please use the power voltage regulator to supply power;

3) Check regularly whether the AC power cord is good, and whether the power plug or the power socket is accumulated in the dust;

4) If the controller is abnormal, or an abnormal sound or smell is emitted, or the controller is hot until it cannot be touched, please stop using it immediately, and unplug the AC power line plug and all other connectors in the power socket.

5) If the controller fails, please contact the after -sales service personnel to get necessary help.

4. Use And Maintain

1) Please do not throw, fall or step on the control system to avoid the control system from being damaged by strong external force impact;

2) Please do not insert the foreign body into the connector part of the controller;

3) Please do not pour water or other liquids into the internal or controller;

4) Do not touch the AC power line terminal with wet hands;

5) Please do not allow dust or foreign bodies to accumulate around the terminal of the AC power supply. Dust and foreign objects accumulated on the AC electrical terminal may cause fire or cause electric shock;

6) Please unplug the power cord when cleaning the controller.

1. Brief Description

The function of the CR777 co -rail injection device detection table is to imitate the working conditions of the diesel engine ECU (Engine Control Unit). The rail sprayer is done; the driver signal parameter user can set it according to their actual situation and save it to facilitate maintenance personnel to judge and repair the working status of the high -voltage common rail system.
