The switch can not work normally occurs, please first press the reset button to see whether troubleshooting, then check the main standby switch into the wire, two sampling line is normal, whether there is loose, virtual connector connected. The following reference for troubleshooting.
The switch can not work normally occurs, please first press the reset button to see whether troubleshooting, then check the main standby switch into the wire, two sampling line is normal, whether there is loose, virtual connector connected. The following reference for troubleshooting.
One, the access power automatic transfer switch does not act, the controller does not light
The possible position:
1 installation wiring is connected properly and then
2 whether the fuse fuse fusible core
Solution:
1 check the circuit breaker into the line side off and pick up the deficiency, such as off reset
2 to 3 pole ATS neutral line should be neutral terminal access
3 replacing the fuse
Two, access to power automatic conversion switch does not work, the controller lights
The possible position:
1 automatic conversion switch is not an automatic position
2 automatic conversion switch delay adjustment is too long
Solution:
1 automatic conversion switch automatic / manual switch in manual position, and B type controller automatically switch lights not in auto
2 automatic conversion switch arranged on the cast from the not self complex or mutual standby state. Can"t spare circuit main circuit, such as the need to change for automatic recovery state to re adjust the dial switch and controller settings
3 automatic conversion of electrical switching delay is adjusted, re adjust the delay dial switch and controller settings
Three, the power supply controller lights flashing
The possible position:
1 into the line A. power fault overvoltage power B. power line connection is bad C. controller failure
2 power lights, buzzer alarm
Solution:
1 re adjust the incoming power supply voltage
2 check whether the power into the line broken phase, or the phenomenon of virtual connection, such as the existence of then, including sampling line automatic conversion electric appliance.
The 3 controller card re inserted or replace the controller.
The 4 lines into the neutral line and phase line of power end of reverse connection, reshuffled connected.
Four, automatic transfer switch tripping lights
The possible position:
The 1 transport causes automatic conversion electric circuit breaker tripping
Circuit breaker tripping caused by automatic switching electrical appliances used in 2
Solution:
1 if the transportation cause of molded case circuit breaker tripping, then button to manually after the automatic state automatic switching and the need to press the reset button and then the automatic conversion
In 2 by the use of automatic conversion of molded case circuit breaker tripping electric appliances, should first check the breaker load
1) if it is short circuit causes tripping, first will short-circuit phenomenon excluded after manual or automatic conversion, such as in the design of the eliminating manual or automatic conversion is easy to cause two short circuit or the emergence of personal injury shall not be short circuit fault condition.
2) under the condition of overload tripping, first check the electrical equipment loads, and to check the ATS the use of molded case circuit breaker rated current to meet the load, if not meet should be possible to replace moulded case circuit breaker, otherwise it will cause the circuit breaker tripping caused by frequent breaker static contact burning, influence power supply system.
Five, the controller working lamp is normal, ATS is not converted
The possible position:
1.B type controller panel wiring fault indicator light
The 2 part plug-in controller virtual connection
The 3 controller is not working
Solution:
1 will be the first panel indicator plug unplug, on ATS power test, if you switch to normal, please re connect the right panel indicator line
2 the A type or B type controller card off after the re inserted, inserted after test again.
The 3.ATS controller may be due to overpressure field voltage or other causes of damage to the same specification replacement controller, controller.
