Terminal

Control logic

1. The on- off switch operation car only be allowed when the interlocking signal is working.
2. In the process of on-off switch operation, the controller shall still execute the original operation when input the on-off order.
3. In the process oi on-off switch operation, the controller shall stop working when press the Reset/sudden stop button, o signal is inoperative.
4. The controller shall delay 0.3s. stop 1s. then reverse 0.3s when electric mechanism is up to ton position. at the controller has not reversed as for power failure when the mechanism reaches on position, fit should reverse 03. again when power is normal.( it can only be operated when the earth switch is in in position)
5. When it is locked-rotor protected, the controller shall revered 1.5s after stop operation. The setting value for locked-rotor current is tentatively 1.8A.
6. The operation is forbid within 4s upon the completion of in-off switch (including is reverse time).
