1. overview
1.1 QCJK-ZF-KM self-startup control box is fully compatible with ComAp's InteliDrive Marine, and has been improved in many specific situations in China, so it is more reliable and stable.
1.2 It integrates many functions such as measurement, display, control and protection, and can meet the automatic control requirements of different types of generating units for users. 1.3 module contains powerful microprocessor, which can realize a series of complex functions.
1.3.1 icon based LCD LCD display;
1.3.2 Measuring, displaying and monitoring the output of generator set, engine speed, oil pressure, water temperature, battery voltage and operation time, etc.
1.3.3 uses built-in relay output to monitor and alarm the running state and fault condition of the unit.
1.3.4 control panel sets the operation parameters and selects various control modes. 2. preparation before use of controller.
2.1 confirm that the controller has been installed and fixed, and its installation environment meets the requirements.
2.2 The connection mode of all control wires of the controller conforms to the electrical specifications. It is especially necessary to confirm the type of generator and DC power supply with fuse fuse protection and correct polarity.
2.3 connect the DC power supply, confirm that the parameters are consistent with the configuration of the unit. 3. the meaning and use of control switch and button. "Power selection switch": when the switch is "open", the control panel is in power up state. Follow up switch: when the switch is "open", the "speed down / speed up" selector switch is effective. "Speed-down/Speed-up" Selection Switch: When the "follow" Selection Switch is switched to "on", the speed-regulating board will slow down when the switch is switched to "speed-down", and when the switch is switched to "speed-up", the speed-regulating board will speed-up. "Alarm Elimination" button: When the governor board in the control box fails to stop, press the "Alarm Elimination" button, and the governor board enters the reset state;
"Emergency stop" button: for duty personnel to manually control emergency shutdown of diesel engines. By using this button, the actuator can be manually controlled to cut off the fuel line, and the diesel engine group can be forced to stop. 4. Indicator light
1. "Main power supply": when the control box power is connected to the storage battery, the "main power" indicator light is always on.
2, "standby power supply": when the control box power is connected to AC220V, the "standby power" indicator light is always on.
3. "Non-servo": When the "servo" switch on the operation panel is turned on, the indicator lights are always on.
4, "exhaust baffle": when the exhaust baffle is closed, the indicator light will always shine.
5, "exhaust baffle opens": when the exhaust baffle is opened, the indicator light is always bright.
6. "Start Interlock": When the terminals of the short connection control box are arranged X2:B-and 652, the control box can not start and the indicator light is always on.
7, "buzzer": when any parameter exceeds the limit alarm, the acousto-optic alarm signal is issued.
8, "fault alarm": when any parameter is limited to alarm, the acousto-optic alarm signal is issued.
9, "shutdown": when any parameter is limited to alarm and stop, light alarm signal is issued. 5. Installation and external wiring
(1) the installation position of sensors and actuators.
1. The pressure sensor is fastened to the main oil road of diesel engine oil, and the cable is connected between the pressure sensor and the monitor.
2. The oil temperature sensor is fastened to the outlet of the diesel engine oil circulation, and the connection thread should be sealed. The oil temperature sensor and monitor are connected by cables.
3. The water temperature sensor is fastened to the outlet of the circulating water of the diesel engine, and the connection thread should be sealed. The water temperature sensor and the monitor are connected by cables.
4. The speed sensor is fastened to the observation cover of the flywheel housing. When installed, the sensor rotates to the contact gear and withdraws from the half ring to keep the gear perpendicular to the sensor. The installation gap between the speed measuring head and the gear ring is 0.5-1.0 mm. The speed sensor and the monitor are connected by a shielded cable with plastic sheathes.
5. After installation, users should take protective measures at the sensor plug to prevent water and oil infiltration.
(2) connection between diesel engine and monitor.
According to the "wiring schematic diagram" of random packing, the attachment bundles of the control box are connected one by one according to the schematic diagram.
(3) When connecting the control box to the storage battery, it is necessary to pay attention to the positive and negative polarity and connect the control box according to the "wiring schematic diagram" of random packing.
(4) start of control box and diesel engine.
When using external power supply to charge the battery, the power switch of the control box must be placed in the "off" position first; when the switch is over and the battery is normally charged, the power switch of the control box should be opened again.
Before starting the diesel engine, the power switch of the control box should be turned on. After several seconds, the control box will start the diesel engine when it enters the normal working state.
The battery is supplied to the control box as the working power supply, and the voltage should be between 18V and 32V.
For electric-start diesel engine, if the battery capacity is insufficient, the battery voltage will drop dramatically during start-up due to the large start-up current, which will cause the control box to work abnormally because of the low voltage. At this time, it is suggested that a battery of batteries be separately used for the control box or the battery will be charged and renewed. 6. warranty period
The warranty period of this product is the same as that of diesel engine units. The company is responsible for repairing the product quality problems free of charge. The man-made faults are not covered by the warranty.
The warranty period of the product is within one year from the date of the factory, and the quality problem of the product is repaired by our factory without compensation.
