electricity machinery with mechanical interlocks intellectual controller etc all the devices are installed on one panel And the controller interior is intellectual auto controlling circuit made of MOTOROLA single chip micyoco SCM and advanced reliable electronic component 1 Working principle of auto controller The auto controller tests the three phases voltage of normal and reserved power supply in the same time when the numerical is 110 higher than the rated one the controller views it as over voltage 60 85 lower than the rated one is under voltage the user can set the specific parameter freely The internal circuit judges the test result of the timely phase for six voltages margin When the result passes the relay it drives the related relay give the open and close orders to the electricity machinery operating structure And the above test result will be showed by some LEDs on the panel There are four working ways automatic and manual normal power supply reserved power supply release transfer delay time and the under voltage numerical can be set through six push button switches The switches are installed on the panel 2 Test and control function of auto controller 2 1 self input and self recover auto controller TKQ2 is used for the auto transforming between the normal power supply and reserved power supply In usual time the power was supplied by the normal power supply and when it become abnormal any single phase is over voltage under voltage interrupted phase the reserved power supply will work after the appropriate delay when the normal power supply refined it will work once again automatically Make sure the reserved power supply is no damaged When it has some abnormal situation the related LED on the panel will turn yellow and the internal buzzer will

supplied by the normal power supply and when it becomes abnormal any single phase is over voltage under voltage interrupted phase the intellectual controller orders to release the electricity by offering a controlling request as well as a unloading order when the generator s capacity is limited user can unload the unimportant section When the generating voltage is up to 85 of the rated one the power of power grid will be cut automatically after some delay and after some other delays the generating power supply will work automatically When the normal power supply recovers it will work

to do the following things before use the ATS read the instruction carefully before installing and using ATS ATS must be used in the normal working condition Check the circuit breaker to see if their specifications are complied with the work condition before installation Before installing measure the insulating resistance of the circuit breakers with 500V Katherine Ohm meter 兆欧表 please note that when measuring the insulating resistance please cut the second circuit lead which jointed to the circuit breaker otherwise the auto transfer controller will be damaged The resistance should not be less than 10M when the ambient temperature is 20 5 and relative humidity is 50 70 Otherwise the circuit breaker must be dryinged to make sure the insulating resistance achieve the standard require When installing the safety distance of ATS must be complied with GB14048 1 When installing make sure there is no conductive abnormal things on the circuit breaker When installing the conductive bus bar which connected to the ATS s circuit breaker must be smooth No attached mechanical strength is allowed to impose on the circuit breaker avoiding to damage them and their motion character After install the switch choose the leads with suitable section to joint the circuit breaer s output and input terminals according to the rated current The four pole circuit breaker can joint no lead only to joint the input terminal Make sure the null line must be joint correct otherwise the intellectual controller and motor operating structure will be damaged As for three pole circuit breaker there in a N line must be jointed to the N terminal on the switch body bracket Notice the phase of the two circuit breakers must be coincident and the switch body must be connected to the earth reliably 2 manual control and regulation self input and self recover When the normal reserved and controller power supply are connected the digital tube on the top of controller panel shows two numerical value rows phase indicative lamps A B C flash circularly state indicative lamps three colors show the normal power supply green close reserved power supply red open that means the ATS works under the good condition If the state indicate lamps are yellow there is a fault exist in the relative circuit three colors of the state indicative lamp respectively means three state close green open red fault yellow Press the normal power supply button QN circuit breaker close Press the reserved power supply button QN circuit breaker open and QR circuit breaker will close after delay t2 Press the normal power supply button QR circuit breaker open and QN circuit breaker close after delay t2 then press cut reclose button the circuit breaker will be open instantly if it is close before electrifying Press auto button it will come to the auto controlling state according to the using power supply And the closing indicative lamp should be lighted or put out in the operating process The released indicative lamp can be tested if necessary Open the transfer switch s veil after circuit breaker is close then press the urgent released button the released indicative lamp on the intellectual controller will be lighted after the circuit breaker is 脱扣 and it will be put out after reclosing Notice when a circuit breaker is 脱扣 the controller must be transferred to mutual press cut reclose button to make the released circuit breaker reclose then can be transferred to auto state let the circuit close Using method After the above regulating the normal TKQ2 system can be used Before operating if choose self input and self recover only to press auto button the auto indicative lamp on the panel will light and the normal power supply is the preferential supply if choose self input without self recover you can select any one circuit power supply to work only to press its button The usage of the function key 1 power supply key cut and connect the power supply which is on the main panel 2 set key press this key the system can be transferred among three states normal showing set under voltage percentage A 1 set cutting delay time A 2 set close delay time A 3 showing normally 3 auto key press this key the indicative lamp light the system can be set at the self input and self recover state 4 normal power supply key press this key the normal power supplier offer the power to the system and it is at the self input without self recover state 5 reserved power supply key press this key the reserved power supplier offer the power to the system and it is at the self input without self recover state 6 release key press this key the system will be released 7 under the set state the normal power supply key is used to add the set numeral key and the reserved power supply is used for reduce the set numeral key Analysis and remove the fault If no response offered when start the switch and the mechanical interlocking driver has no motion after pressing the indicative button please check the power supply and connection of circuit breakers Three phase power supply and the N line must be jointed correctly intellectual controller socket must be screw down well contact When controller was power supplied but the mechanical interlocking driver has no motion please check the fuse of the auto controller to see if it is burned up for over current of the motor operating structure Please retry after taking another suitable fuse The fuse is burned up frequently please check the mechanical interlocking driver to see if it is locked Please retry after some adjustment Other notice 1 Check and maintain the switch termly according to th
