2. Product overview
Automatic transfer switch (class CB)is used to ensure power supply for different occasions . You can operate the automatic transfer switch either electrically or manually.
| S/N | state | analysis | action |
1 |
Power supply normally, the controller without any display | 1.Cables are not connected terminals 2.The cable has loosen which it was connected controller and changeover switch. | 1.Check it and connect it again 2.Check it and plug in again |
2 |
Controller is connected, but it can not automatic transfer. | 1.Control unit or changeover switch is on manual state, or electrical locking ,or handle mounted. 2.Terminal loose 3.Fuse is broken 4.delay time setting is wrong 5.Fire fighting signal input to controller 6.Voltage is out of the normal range | 1.Change to automatic Mode or relieve electrical locking or remove the handle 2.Check it and plug in again 3.Change fuse 4.Modify the delay time setting 5.Cancel the fire fighting signal 6.Check voltage, make sure the voltage range in 70% ~130%. |
3 |
OTM_C_D transfer continually | 1.loose or poor connect between cable and terminal 2.Voltage fluctuating, and the fluctuation range beyond the overvoltage or under voltage setting value | 1.Check the connections 2.Reset the value of overvoltage or under-voltage(eg.change115% to 125%) or enlarge changeover delay time setting |
| 4 | Primary line is normal, but DPT change to secondary line | terminal connection loose(primary line terminal or control unit connection) | Check and troubleshooting |
5 |
Fire fighting fault |
1.fire fighting is not 24V d.c. 2.fire fighting signal is in wrong polarity 3.fire fighting signal lasts less than 1 second |
Please input the correct fire fighting signal, it must be 24V.d.c.and last more than 1 second. |
6 | Power supply normally, but control unit display phase lost | 1.loose or poor connect between cable and terminal |
Check and troubleshooting |
7 | CB010 has been at trouble alarm | 1.line loss phase missing 2.N pole is connected mistakenly to A,B or C phase |
Check and troubleshooting |
8 | CB011 has been at overvoltage alarm | 1.Line overvoltage 2.N pole is connected mistakenly to A,B or C phase |
Check and troubleshooting |
