8. Debugging and installation
8.1 debugging
*Before installation please click the following method for debugging, commissioning normal rear can put into use.
8.1.1Master for each drop test
8.1.1.1 press the logo, on the controller to form a complete set of corresponding air on cable and device of high voltage vacuum circuit breaker socket installation, tighten.
8.1.1.2 to the master, for power supply.
8.1.1.3 open two power switch of the controller, the product into the working state.The electric power supply, often if common power supply back knife switches in the closing position, the time delay device of high voltage vacuum circuit breaker closing transmission after 5 seconds;If a common power supply in standby power breaker back shots back switching states or other states, first make brake device of high voltage vacuum circuit breaker points, has confirmed that it is in a state of break-brake, after a delay on commonly used power shots back knife switches, again in the case of confirmed breaker has been in place, then delay after 5 seconds to device of high voltage vacuum circuit breaker closing.Closed electric switch, controller to detect common power loss, after the above processing steps, first make brake device of high voltage vacuum circuit breaker points, and then cast in standby power cast back knife switches, to make the device of high voltage vacuum circuit breaker switching power, to complete a conversion process (often electricity - for electricity).Again open the electric switch, controller to detect common power supply, automatic make brake device of high voltage vacuum circuit breaker points, breaker commonly used power shots back again, and then make the device of high voltage vacuum circuit breaker closing, to complete a conversion process (for electricity - often electricity).
8.1.2Over-current protection
This product factory set data flow for current transformer secondary side 5 a, quick break for 15 a secondary side, according to the user's need to make changes.Through raising the inverter for high voltage vacuum circuit breaker with large current, make the secondary side current is greater than 5 a, conversion device due to flow will be closing atresia treated the breaker closing work in current device of high voltage vacuum circuit breaker, two power supplies are not automatic conversion.Unlock method for manual press the corresponding closing unlock button on the panel, or by remote control by remote control switch to unlock.
8.1.3Remote debugging
8.1.3.1 remote control points, closing operation: the dual power switch device is equipped with remote control, wireless remote control points, closing operation can be:
Break-brake 8.1.3.2 remote control operation: continue to push the "lock" button on the remote control more than 2 seconds to break-brake operations, plant will be closing closure treatment at the same time.
8.1.3.3 remote closing operation: continue to push the "lock" button on the remote control for closing the unlock operation for more than 2 seconds.
8.1.4Set the LCD display

 

 

 

 

 

8.1.4.1 panel use high-grade green backlit LCD display in Chinese large screen display working status, normal operation of the open weak backlighting to facilitate observation in any environment.After the long press "set" key for 2 seconds, the controller into the Settings menu tree, at the same time strong backlight light in order to clear view and modify the parameters.
8.1.4.2 display on the LCD display common power supply (NA, NB, NC), standby power (RA, RB, RC), all the way when any uneven power supply power failure, the power supply corresponds to the letter.When any power failure happened all the way to cut off the power supply and issue a report to the police.
8.1.4.3 controller parameter Settings
Example: the original set as factory default, now changed to N - > R time 20 s, R - N time for 5 s
A. enter the parameter setting mode
In normal display mode, long press "set" key for 2 seconds and then released, the controller will enter the parameter setting mode, strong backlighting lighting at the same time, the LCD will display the set time N - R interface.

B. changes commonly used power transfer to standby power delay time
LCD display N - R time, through the panel on the "key", "reduction" of time step increase, decreases.If long press "add", "key reduction" super 2 seconds will enter a rapid mode, increase and decrease the time value will be quick to add and subtract operations, release the button to stop.Users can cooperate treatment in accordance with the specific circumstances, to quickly and accurately set the parameter values.



C. changes standby power conversion to standby power delay time
Continue to short press "set" key, the LCD screen display R - N time, through panel "with key" and "reduction" of time step increase, decreases.If long press "add", "key reduction" super 2 seconds will enter a rapid mode, increase and decrease the time value will be quick to add and subtract operations, release the button to stop.Users can cooperate treatment in accordance with the specific circumstances, to quickly and accurately set the parameter values.

D to change the dual alarm mode
Continue to short press "set" key, the LCD screen display way of BJ, through panel "with key" "minus key" alarm way step change."ON "said the police open," OFF "said the police shut down.

E exit parameters setting mode
Continue to short press "set" key, the above steps 2 ~ 4 automatic controller will cycle.If set to complete want to exit the parameter setting mode, please long press "set" key for 3 seconds to exit parameters setting mode, return to normal display.If they do not press any key and wait for 20 seconds automatic controller can automatically exit parameters setting mode, return to the normal display interface.

 

Note: in the process of setting, such as do not need to modify the parameters, direct short press "set" key to enter the next item parameter Settings.On to the next parameter is set at the same time, a modified content parameters on the fast preservation. The user does not have to show each loop wheel, modify the finish can be according to the above step 5 operating mode exit parameters setting mode, please check it again after the set to complete.

Note: dual power supply for each unit and high pressure PT when installation, please press the high voltage safety insulation distance isolation installation.Cable used in high voltage side must adopt corresponding voltage grade high voltage cable, and follow the relevant safety insulation distance line.All equipment must be safe and reliable grounding.Low voltage side cable should also pay attention to safety wiring insulation distance.
9.3 installation method

 


10. Failure analysis and elimination
10.1 the situation of the work on the open intelligent controller panel after master the electricity, the electric power switch, panel status to the supply switching lights all the way, the other points all the way brake lights, or both road show the brake light is lit.The LCD panel is displayed according to the pattern shown in this manual 8.1.4.
10.2 when the intelligent controller work, if you hear a voice squeaky relay jitter inside, please close the master electrical and intelligent controller on the front panel electric power switch, check whether the power supply voltage is too low, and start to restore normal voltage controller.
10.3 after Lord for electric power automatic control device not conversion, please check the intelligent controller panel left and right sides of the main power and electric power switch is on.Controller and whether institutions corresponding air plug screw tightly, at the same time observe the controller panel LCD display on the main power, whether for electric undervoltage (phase).
10.4 after automatic conversion switch institutions and points, please manual inspection agencies is closing in place.
10.5 such as remote control remote control no response, please check whether the remote control right of form a complete set (the number on the reverse of the remote control should be consistent with the body on the remote control code), remote control electric, operation specification, the controller outside antenna is normal, whether there is a strong electromagnetic interference in the environment.
10.6 flow regulating current too high or too low, please test the transformer and the heat flow device whether formal whether accurate.
Note: when the power switch overload or manual brake, you must manually switching (also known as unlock) cannot normal transformation.When debugging when the main electricity have electric power, main electricity not switching to use manual switching.When the main electric power for electric also want to use manual switching to unlock, without closing this debugging to normal before normal put into use.
