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.

NO.1

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.

NO.2

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.

NO.3

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.

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.

HAT821

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.

ATA821

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.

ATA821MN

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!
