SmartGen | Troubleshooting Methods of Remote Start Paradox

It seems that there is no connection between remote start signal and paradox, so why put them together? Read on, the answer will come out.

Let’s introduce “Fault Symptom” first: customer gives feedback that all three units in three different locations fail to start remotely.


Fault symptom: Customer said that after the first remote auto start failure, and manual alarm was reset, the second time whether manual or auto start, genset could operate normally.
Fault reason analysis: This is an 900kW ECU unit, and due to the large engine, it is equipped with an electric pre-supply pump to supply fuel to the system before starting the engine, so as to ensure the necessary lubrication of each friction interface during the crank process. The required pre-supply time is 30s, and the oil pressure should reach 150kPa when engine ECU detects crank. But the (pre-heat time) pre-supply time set by controller is only 2s. Therefore, oil pressure is difficult to reach 150kPa when engine is cold starting. ECU issues oil pressure low shutdown alarm and unit failed to crank.
Solution: Set (pre-heat time) pre-supply time as 30s by controller and change controller crank disconnect condition from “frequency + oil pressure” to “frequency + speed”. The positive pole of ECU main power and ignition switch signal line are connected in parallel to controller’s FUEL output, and fuel output time is set to 5s. After the above parameter setting is finished and remote start signal is active, unit cranks success.


Fault symptom: Customer said that genset couldn’t start automatically when mains power off.
Fault reason analysis: Under normal operation, the unit will start automatically after the remote start input port of the controller is linked to close by external closed contacts. Reasons for not start automatically: 1. Problem of remote start signal; 2. Problem of Controller.
Fault finding:
1.Set controller in auto mode, and make remote start input port and common ground short connected with wire, controller start automatically. Controller problem is excluded.
2.In this case, the normally closed contacts of external AC220V relay is used as remote start signal to output. When mains signal is disconnected, relay normally closed contacts do not close and relay function is abnormal.
Solution: After replacing AC220V relay, remote start signal recovers normal and problem is solved.


Fault symptom: Customer said that genset always failed to crank whether manual or auto start, controller issued low oil pressure shutdown.
Fault reason analysis: If low oil pressure shutdown occurs frequently during cranking, It is speculated that the engine may not really start successfully, and the oil pressure may be selected under the successful starting conditions. Oil pressure is often low and unstable during cranking, especially in winter.
Fault finding: Open controller parameter setting and view selection of crank disconnect conditions. You can see that customer chooses “frequency + oil pressure”, and controller’s speed signal sampling does not connect to speed sensor.
Solution: Change the crank disconnect conditions to “speed + frequency”, make speed signal paralleled to speed sampling of GOV board (speed sampling of GOV board is connected to speed sensor). When remote start signal is active, auto start is normal; start the unit manually, unit cranks normally.

The solutions of above 3 cases are involved the root cause. Seeing the symptom through the essence perfectly explains the “paradox” of the title.
Summary: For situation similar to remote start, unit crank failure, it appears to be unit crank failure, but in fact this fault is caused by various reasons, which are summarized in the following table. We hope these cases can help you to deal with similar problems accurately and quickly.

SmartGen | Triple Protection, Free Transfer—2-line 1-bus-tie

HAT821, SmartGen two-line one-bus-tie controller released in 2018, has perfect and mature functions after two years of technical accumulation and market integration.

At the same time, we have developed two bus-tie controller adapters and supporting wiring harnesses, and added synchronous parallel transfer function (HAT821S), to meet the demand of different customers. This has been well received by customers and has delivered a satisfactory answer for customers who are using it.

Logic interlock and electrical interlock are very important part in two-line one-bus-tie system. To ensure the reliable operation of transfer switch, we use the adapter with controller logic lock to achieve triple interlock.

Primary Interlock: Controller Logic Lock

Logic interlock is realized by controller’s powerful software function. In the non-parallel transfer mode, if two breakers have closed, ensure that the third breaker will not close.


Double Interlock: Electrical Interlock via ATA821 Adapter

Through the coordination of ATA821 adapter and switch auxiliary contacts, two sets of normally closed contacts of each breaker switch are used to interlock the closing output signal of controller, avoiding the malfunction caused by the contact adhesion of closing relay due to the damage of controller.


Triple Interlock: Electrical Interlock via ATA821MN Adapter

Through the coordination of ATA821MN adapter and switch auxiliary contacts, four sets of normally closed contacts of each breaker switch are used to interlock controller’s closing signal and undervoltage tripper of each switch, avoiding the misoperation when the user use the switch body button to close breaker. If two breakers have been closed, the undervoltage trip coil of the third breaker will be powered off, and cannot be closed even with the switch body button.


Controller logic lock + electrical interlock of closing signal + electrical interlock of undervoltage tripper, triple interlock, triple protection. Make transfer more reliable, make power utilization safer!

SmartGen | Striving to Move Forward with Full Energy

——2020-2021 Development Review of Electronic Control Workshop

Fast forward to 2021, when writing this article, it is the time for electronic control workshop to work orderly and make capacity improvement at full steam. Looking at the focused eyes of the staffs while working and the continuous products output on the newly added production line, I involuntarily think back to the previous time.

Once upon a time, the electronic control workshop in the production center was troubled by the few orders, poor efficiency, and production quality was controlled by manual inspection. The development of the whole department seems to have encountered a bottleneck, which is incompatible with the situation of the company’s frequent success reports. The director scratched his head and staffs were demoralized. What should we do to solve the difficulty?

At the beginning of 2020, department leaders and workshop staffs gathered together to list the current situation of the workshop one by one, making everyone deeply aware that “Unless change, otherwise a dead end!” Change started with the director. The director changed the concept, adjusted the leaders and clarified the rules and direction of production management in the workshop. What ignited was the passion of all leaders and staffs, what broke through was the barrier of inertial thinking. Soon, the efficiency was improved, the orders from big customers came in droves, the staff turnover rate was also dropped dramatically, and the workshop soul was created.

Be prepared for crisis is necessary for us. A moment of success is important, but if you want to be excellent all the time, you have to constantly summarize and improve, and firmly grasp the pulse of the workshop progress. Therefore, the main purpose of this article is to review past year and summarize the good experience.

Firstly, cultivate a strong team with people as the core. The company leaders often hire external elites and internal backbones for management knowledge, management methods and other trainings. In various trainings, the electronic control workshop gradually and systematically understands the core of workshop management and gradually practice it, which has also achieved good results.

The workshop constantly makes efforts to cultivate management backbone, technical backbone, and technical experts, to activate the working atmosphere of the staff, to enhance the enthusiasm of the staff, and to conduct technical competitions and production skills assessment regularly. We hold various recreational activities such as table tennis, badminton competitions, chess game, performance during break time.

Then, hold high the banner of “continuous improvement”, and continue to transform and optimize the production line with a focus on efficiency:

The daily delivery capacity of HT22M series small heaters can reach 50 sets at most. After many initial tests of one stream production mode, simulated operation, and the joint efforts of equipment and process department, electronic control workshop, and R&D center, the small heater has added an automatic belt production line. After several operations, line balance adjustment and other optimization and transformation, the daily delivery capacity has reached 150 sets. At the same time, the dry air tightness test transformation is being carried out on the line, and the daily delivery capacity of 200 sets will soon be realized! The operation action decomposition of each process, standardized operation methods, high-precision air tightness test equipment, strict insulation and voltage withstand test standard for testing, ensure the production of high-quality small heaters.

The orders of marine machine production line are mostly tailored for customers, “private customization” with high-quality lean production. But in order to improve the delivery capacity, equipment and process department and workshop also make a series of improvements. Specially designed L-shaped production line for marine machine, SOP, tools and materials are placed nearby. The production cycle of marine machine products is greatly shortened by designing the wiring line length in advance, processing wire early and working in different processes.

In order to meet the increasing order demand of customers, GCPB series backpack cabinet production line has been improved in one stream production mode operation for many times, one stream production mode operation of general assembly line; one stream production mode operation of bottom board wiring plus general assembly line; one stream production mode operation of controller wiring of heater control box, bottom board wiring plus general assembly production. The backpack cabinet production line not only has a daily delivery capacity of 100 sets, but can flexibly switch to produce more than 10 batch products of various types, such as heater control cabinet. Because the action decomposition and standardized operation, the operation difficulty is reduced and the product quality is effectively guaranteed.

HWP series large heater production line is being tested and simulated to run one stream production mode and can provide data and scheme feasibility for the transformation of automatic production line. Currently the control box is produced separately and the daily delivery capacity of large heaters has reached 50 sets.

Every production line transformation, all station improvements, pieces of SOP writing, each careful communication, groups of wire installation, steel pipe construction one by one, cooperation and operation over and over again, every bit of advice, clap and praise every time……

A workshop with the spirit of unity, technical leadership and continuous improvement is in full swing.

Looking back is to make great strides forward.

Let’s work together, let’s inspire each other, and strive forward with full energy. The history of electronic control workshop will leave the footprints of our youth!
