Open-collector output pin for indicating the system
fault condition.
When no system fault, this pin will be conducted
to GND.
When system fault occured, this pin will be highimpedance. |
| 2 |
TEST-IN |
OUTPUT |
When this pin been conducted to 0VDC, module will calculate the zero-point-drift and store the value to register in the MCU to finish the callbration operation.
After calibration finished, system will internally generate simulated residual current, to check whether module can do the correct response.During this procedure, X30-OUT & X6-OUT will turn to highimpedance if module working correct.
Attention:
When using the TEST-IN function, the main circuit must be cut-off to ensure no r esidual current flow When using this pin function, please follow the time diagram figure. |

X6-OUT |
OUTPUT |
If residual current exceeds pre-set DC trippling value(for this module typically 4.6 mADC),this output is in a high-impedance state When the total residual current r.m.s exceeds pre-set all-current trippling value, this output is in a highimpedance state
When system-fault happens, this output is in a highimpedance state.
For other normal conditions, this output is in a low
level(GND) |

X30-OUT |
OUTPUT |
If residual current exceeds pre-set all-current tripping value (for pure-AC typically 23 mAAC), this output is in a high-impedance state.
When system-fault happens, this output is in a highimpedance state.
For other normal conditions, this output is in a low
level(GND) |
