Product introduction:

���This device a dedicated control device specially designed for the oil-submerged pump type tax-control oil filling machine and its control mode is the centralized control system and can make distribution according to actual layout of the filling station. Its connection of leads is numbered, which is convenient for protection and maintenance.

Key functions:

�����Earth leakage protection: When the insulation property of electric wiring of the oil filling unit degrades and its housing is electrified, the control box can switch off the DPS rapidly so as to ensure the safety of person body, equipment and oil stations.
�����Short circuit protection: When the electric wiring of oil filling unit is shorted out, the control box can switch off the DPS rapidly so as to maintain the safety of electric wiring and the service life of the equipment.
�����Overcurrent protection: When the running current exceeds the rated working current for the oil filling device, the control box can rapidly switch off the DPS so as to ensure the safety and service life of the oil filling device.
�����Insulation blocking: When a single machine requires maintaining due to failure, it only requires switching off the associated power source between this machine and the system in the control box so as to carry out the maintenance, but there is no need to switch off the power of the whole system. The insulation blocking has the function preventing the reverse delivery of current of the system so as to guarantee that the maintainers will not get an electric shock and no firing occurs, which dangers other oil filling machines under normal use.
�����Fault indication: When the input power or the operation of the oil submerged pump is abnormal, the control box can give indication so as to prevent unnecessary supervention.
�����Emergency turnoff: When the oil filling machine is under the fortuitous event (saying, an automobile knocks over the oil filling machine, the oil pipe is pulled apart and it is out of control artificially and etc.), the emergency shut-down button of this control box can be used to switch off the power of all devices so as to prevent further occurrence of accidents.

Technical indicators:
�����Rated voltage: AC380CV±10%
�����Earth leakage protection: smaller than 30mA
�����Overcurrent protection: 6A
