6410-001-C-N-N drive controller

If a cooling plate is not provided, the optional heatsink available from Pacific Scientific can be mounted to the side of the 6410 and the combined unit mounted to a panel using the slots on the back of the 6410-001-C-N-N as described above (bookcase mounting). With a minimum unobstructed space of four inches above and below the unit, and cooling accomplished solely through convection (no fan), the 6410-001-C-N-N can be run at 5 Amps RMS maximum for ambient temperatures of 25°C or less and 2.5 Amps RMS maximum for ambient temperatures of 45°C or less.

Using a fan to blow air past the heatsink will increase the allowable current significantly. It is always required that the 6410-001-C-N-N’s chassis temperature not exceed 60°C. It is best to confirm this by direct measurement with a temperature probe during system operation. Any difference between the ambient temperature during the measurement and the worst case should be added to the measured chassis temperature. The resulting sum must be under 60°C.

If the 6410-001-C-N-N is mounted to a panel with no cooling plate and no heat sink, a minimum unobstructed space of four inches above and below and one inch between the side plate and any other object must be provided. If cooling is accomplished solely through convection air flow (no fan), the unit can be run at 2.5 Amps RMS maximum if the ambient temperature is 25°C or less and 1.25 Amps RMS maximum if the ambient temperature is 45°C or less. Again, use of a fan to blow air past the side plate of the 6410 will increase the allowable current. The same considerations given above for the optional heatsink apply.

The control screen of the supercharger includes four sets of screens: the supercharger air circuit screen, the supercharger machine screen, the supercharger oil station screen, and the supercharger parameter monitoring screen, which can display and alarm the operation data of the supercharger in real-time. The operator can complete real-time control of the booster machine, oil station, and related valves through these four screens.

Start and stop control of the turbocharger. The booster can only be started when all three conditions are met simultaneously, including process permission, unit permission, and drive permission. When the booster is started, the anti surge valve should be fully opened and held until the start process is completed. At the same time, the inlet guide vanes need to be closed to the minimum position to ensure that the motor starts without load.

Turbocharger shutdown can be divided into four types: process shutdown, unit shutdown, drive shutdown, and emergency shutdown. When any of the above situations occur, it will cause the turbocharger to malfunction and shut down. After all faults have been eliminated, the “Trip Reset” button needs to be pressed on the screen to reset before the booster can be restarted for the next time.

Control of the booster oil tank electric heater. The start and stop of the oil tank electric heater are mainly automatically controlled by the local temperature switch. The DCS sends a start permission signal, and when the permission signal is 1, the heater is allowed to be put into heating. If the local temperature switch malfunctions and is not disconnected after overheating, an overtemperature signal will be sent to DCS, which will then issue a signal command to shut down the oil tank electric heater.

Control of the turbocharger exhaust fan. The smoke exhaust fan must remain in operation during the operation of the auxiliary oil pump or the booster engine. When the electric control permission signal of the exhaust fan and any start signal of the auxiliary oil pump or booster engine exist, the DCS will send a signal to start the exhaust fan; When the auxiliary oil pump and booster engine are not started or the booster engine stops suddenly, the DCS will stop the exhaust fan.

Control of auxiliary oil pump. The auxiliary oil pump serves as an auxiliary backup for the main oil pump of the supercharger machine, supplying oil to various equipment during the start and stop stages of the supercharger. After the booster starts, the auxiliary oil pump will still be in operation until the booster runs at full speed; When the turbocharger stops, the auxiliary oil pump will automatically start and continue to run until the lubrication time signal ends; During the operation of the booster, if there is a low lubricating oil pressure, the auxiliary oil pump will automatically start. If there is a low sealing gas pressure, the booster will not interlock and stop because the protection of the booster operation is given priority.

Control of inlet guide vanes. Before starting the turbocharger, the inlet guide vanes are in the fully closed position. After the turbocharger is started, the allowable loading conditions are met and the inlet guide vanes are opened to the “minimum position” opening. When the turbocharger is unloaded, the opening becomes 0. The minimum value MV1 during the operation of the turbocharger is calculated using the following formula: MV=[(100-MV2)/100] * MV1+MV2.

The opening control of the inlet guide vane is determined by the value of MV, and there is a deviation calculation between the actual opening value of the inlet guide vane and the calculated value to monitor the accuracy of the guide vane opening. The deviation is the absolute value of the difference in opening between the two. The minimum opening value of the inlet guide vane is given by the manufacturer. After the turbocharger stops, the inlet guide vanes also need to be closed and placed in the minimum load starting position.
Since its use, the turbocharger control system has operated stably, achieving automatic control of system start stop, interlocking, and protection. It operates safely and reliably, completing the independent control function of the turbocharger and meeting the ideal design requirements.
