VCB Motorized Chassis Truck Electric Chassis DDPC-4-800
To maintain the style of the original chassis, the electric chassis is improved with an electric mechanism from the original chassis 650#, 800#, 1000# and 24KV series, which maintains the character of the original chassis and achieves the electric operation of the chassis’s working position and test position. Therefore, the electric operation and manual operation do not need to be switched, which satisfies the requirements of programmed operation in the power system.
The controller of chassis can achieve the control and protection for the electric mechanism, the controller can brake the motor immediately when the electric mechanism driving motor ( for example, installation is not in the place or mechanism is stuck) an reach the protection condition and reversely drive motor to release the stuck state of the chassis.
Operating Instructions of the electric chassis
Only when the grounding switch and circuit breaker are at opening states, the chassis is allowed to be swung in and out.
When the chassis is equipped with manual operation priority function, under manual operation condition, the electric button of swing in and out cannot be used.
When the chassis is not at working position and test position under nature state, if it is needed to be swung in the working position by electric operation, the chassis must be swung in the test position by manual or electric operation first, then it is moved to the working position by electric operation.
When it needs manual operation after electric operation, the handle must be inserted into it and rotate it about 80°, then reversely rotate it about 30°.
In case that the handle of chassis can not be pulled, to observe whether the angle of the screw rod is in the correct position.
If there is an emergency stop during electric operation process, or there is fault and solved, just press the reset button.

Control Instructions of the chassis
When interlock signal is satisfied, electrical swing in and out operation are allowed.
During electric operation process, enter command of swing in/out, the controller still carries out the original operation.
During electric operation process, press the buttons of swing in/out simultaneously, or when the interlock signal is invalid, the controller will stop the operation.
When the blocking rotation protection condition is satisfied, the controller reversely rotates the mechanism for 200ms after stopping the mechanism action; the first 15 seconds of the blocking rotation protection current is set to 1.2A before swinging in; after 15 seconds, it is set to 4A; it is set to 4A, 7 seconds before swinging out, and 1.2A after 7 seconds.
The time limit for electric swing in/out operation is 80s, when the time is up and the chassis is not in the position, it needs to be stopped and send alarm.
The limit switches at contacts 16,17 are S9,S8 auxiliary switches of the chassis, it needs only simply to connect contact of controller to corresponding contacts of S9 and S8.
If the alarm lights on during electric operation of controller, just press the reset button.
When wiring of motor is carried out, pay attention to positive and negative position of the motor.
Remote swinging in and out can be cooperatively used with the micro-computer protective device.
It can have only one mode during work between remote mode and local mode, other mode can not work when a mode is connected.
If the trolley is not at the test position during electric operation, it needs to be swung out to the test position, then the electric operation can swing the trolley into working position.
Instructions of earthing switch control
Electric open and close operation are allowed when the interlock signal is satisfied.
Entering into switch opening and closing instruction during switch opening and closing operation, the controller will still execute the original operation.
If the open/close buttons on the panel are pressed simultaneously or the interlock signal is invalid during switch opening and closing operation, the controller will stop the operation.
The blocking rotation protection condition is satisfied, the blocking rotation protection current setting is set to 1A.
The time limit of electric opening/closing operation is 12s, it needs to stop and send alarm if the time is up and the trolley is not at the position.
The limit switches at contacts 29 and 30 are earthing switches, it needs only simply to connect contact of the controller to corresponding contacts of the switch.
If the alarm lights on during opening and closing operation of the controller, just press the reset button. Please pay attention to the positive and negative position of the motor when wiring.
Remote swinging in and out can also be cooperatively used with protective device of the micro-computer.
It can have only one mode during work between remote mode and local mode, other modes can not work when a mode is connected.
DDPC-4-800 Outline dimension and installation dimension of electric chassis
NOTE: Opening size and mode of installation are as common mode, when the input power is AC/DC 110V, please mark or notice it in advance.
Electric chassis assembly
Installation opening size of panel controller
The four Ø5 openings in right picture are the fix installation openings of controller on the panel, Ø20-40 opening is used for connection cable which goes through inside the controller, the opening is used for data cable of the controller, if has no strict requirement of processing dimension tolerances.
