Seven performance
YDQ5 series terminal type intelligent dual power automatic transfer switch has two operating modes: manual mode and automatic mode.
● Manual operating modes: manual operation mode have common power supply, standby power and double in three works. Manual mode the system will not switch automatically.
Common power: forced off standby power, the power is turned on common.
Standby Power: forced off the common power supply, standby power is turned on.
Double points the way: the two-way power can disconnect all, but also make the trip due to failure of the circuit breaker and then buckle.
● Automatic mode: YDQ5 series terminal type intelligent dual power automatic transfer switch in automatic mode, press control functions can be divided into automatic recovery (R), since the vote of no self-recovery (S) and the grid - Generators ( F) are three first two suitable power supply system, the latter applies to power generator systems.
NOTE: The end of the controller no double points, intelligent manually force double points, automatic operating mode from the vote since the complex only one other property with the same micro-break.

eight main structure and working principle
YDQ5 series terminal type intelligent dual power automatic transfer switch consists of two molded case circuit breakers and accessories, motor drive mechanism, mechanical interlock mechanism, automatic controller and other components, all devices mounted on a metal plate. Internal controller automatic control circuit microcontroller and advanced, reliable electronic components of the composition.

Nine, performance characteristics
The controller for each phase voltage simultaneous two-way power line inspection, when the supply voltage is less than 35% to 40% of rated voltage, the controller determines by comparison, the test results will be sent directly to the controller, and through the delay circuit issue an instruction to convert the electrical operating mechanism after a time delay.
Power from the vote since the complex switch (Time display type, the conversion time is adjustable)
For automatic recovery of switch, control functions shown in Table, under automatic control state, the power from the common power supply is normal, when the normal power supply is abnormal (loss of pressure or lack of any phase occurs) when, after a certain automatically switch to standby power supply after the delay. When the normal power supply back to normal, after a certain delay automatic return to the common power supply.

Automatic recovery switch control Menu

Power - power switch (Time display type, the conversion time is adjustable)
Switch is mostly used for power conversion between two power supplies to be used for two-way power grid and generator conversion between. Grid - generator power supply system, generally as a backup power generator, which controls the functions shown in Table: When the grid voltage is less than 35% to 40% of rated voltage, the generator can be started automatically when the power supply voltage reaches normal ( 80% of rated voltage) when the power supply is turned on. When the grid voltage returns to normal (up to 80% of rated voltage), after a certain delay after the power supply is disconnected from the load circuit, automatically returns to the common power supply.

Power - power switch control Menu

Power end type wrap switch (no phase failure, phase protection functions, the conversion time ≤3s not adjustable)
When the normal power supply voltage loss, disconnect automatic delay common power circuit breaker, close the backup power circuit breaker, when the normal power supply voltage is restored, the standby power circuit breaker disconnect delay, reply to the common power supply. The end of a distribution line is mainly used for firefighting, fans, emergency lighting, water supply and other circuits. TXQ3 standard dual power breaker micro channel structure, especially for lighting, small motor control equipment.
Load lines in the event of an overload or short circuit fault, the switch automatically trip the circuit breaker, the load power is turned off. Be customers after troubleshooting, press the control mode "Manual" button, the circuit breaker re-buckle the operation, and then press the control mode "manual" or "automatic" control form, before the switch to the load.

Ten, structure and working principle
Switch from the three-pole or four-pole circuit breakers as the main power switch and the electric operation with mechanical interlocking institutions;
An intelligent automatic switching controller: delayed closing, phase protection function, automatic conversion, control the selective conversion;
A unique set of mechanical interlocking mechanism: to ensure that the light is not quite at the same time closing the circuit breaker in the conversion process;
A group of electric operation: to achieve automatic closing of the circuit breaker. Electric operating mechanism of the switch operating mechanism using the latest electric mechanism, with a smooth and reliable operation, low operating force and so on.
Install the bottom: for-one switch, mechanical interlocking mechanism and the controller are mounted on the same substrate. Remote control switches on the switch will be separated from the controller and the backplane, use connector, special cable length of about 2m; the controller mounted on the cabinet door.
N is the common power supply, R to standby power. QN for the common power control circuit breaker, QR standby power control circuit breaker.
When selecting manual mode, the choice of two circuit breakers can be artificially "close" and "minute", do not have the automatic conversion.
When selecting automatic mode, according to then use the power into the automatic control state.
Elected with a double sub-state, it can be a full part of two circuit breakers off.

Intelligent Controller descriptions and settings
Intelligent Controller Panel
1, NA, NB, NC commonly used power indication: Battery labeled normal, flashing indicate undervoltage or phase failure; RA, RB, RC standby power.
2. Manual key: You can select the common thought on the controller or power backup.
Auto button: When you use power according into the automatic control state.
Dual Split: make load off from the common power supply and standby power full part; of the cut can be artificially on the operating wrench to rotate the chosen common or alternate.
3, when the system fails, OA flashing, flashing alarm, an alarm sounds at the same time press the minus key figures can be artificially close the alarm sound.

Applicable maintenance
Intelligent controller with manual, automatic, dual operation instruction key points, emergency disconnect operation automatic control, automatic control operation has the following features:
Manual operation: first press manually enter manually, often working state, then press this key to enter the manual standby state. In this case the working status of the power abnormal, sustained three seconds after the automatic protection status will switch to double-points position.
Automatic operation: According to user needs the occasion of its sub-function mode and automatic recovery from a vote of no self-recovery mode categories;
Automatic recovery mode: boot initial default common power supply, when the common power anomalies standby power supply is switched by the delay occurs, such as the common power supply returns to normal after the automatic return from the common power supply backup.
Since the vote of no self-recovery mode: Basic functions above, except that after the common power can not automatically return to normal, still standby power supply, for the common power control mode when you press the "manual" control form, the common power supply before to load.
