b.Operational power supply
Operational power supply of intelligent controller: AC 400V/380V, 230V/220V, 50Hz/60Hz; DC 220V, 110V and 24V.
c.Major protective functions
Measurement & operation monitoring
Inquiry function
Parameter setting function
Function of programming interface
Test function
Self-diagnosis function
Fault clock function (optional)
Historical data recording function (optional)
Load monitoring function (optional)
Making current release(MCR) & override tripping function (Optional)
Setting function of remote control, local control and setting position (this function only for H-type intelligent controller)
Step 1: Confirm setting authority, and the key lock of H-type must point to “SET” position.
Step 2: Confirm that controller is under reset status. If the controller is in non-reset status, press “RETURN” key till current meter display is in
circulating status.
Note: If controller is in fault alarm status, setting function is locked and setting cannot be operated.

Step 3: Press "FUNCTION" button till setting lamp flashes.
Step 4: Press "ENTER" button to make acting current setting of load monitor 1 be displayed in current meter display window, and setting lamp
flashes at that time.
Step 5: Press “▲” and “ ” buttons to selected items to be modified.
Step 6: Press “ENTER” button, and “SET” lamp will in constantly lit status. Press “▲” and “ ” buttons to make required values with
adjustment. Press “ENTER” button again, and “MEMORY” lamp flashes once indicating parameters have been stored. If you don't
want to store this data, press “RETURN” button directly, and parameters haven't been modified and will keep the original value.
Step 7: Press “RETURN” button once, “SET” lamp will flash. If you need to modify other parameters, just repeat step 5 and step 6. Otherwise,
press “RETURN” button till “SET” lamp is turned off.
Note: If there is any failure while it's in setting status, it will exit from setting status and enter fault status automatically. While adjusting parameters,
the longer you press “▲” and “ ” buttons, the higher the gradual accelerating or decelerating speed will be.
Display contents of current meters and protective type indicators with different parameters are as follows.
owed as 4.20S in the right diagram.
Fault inquiry operation
Step 1: Confirm controller is in reset status.
Step 2: Press “FUNCTION” button till inquiry flashes. Press “ENTER” button, and “SEARCH” lamp will be lit constantly and display window
of current meter displays fault acting value and delay time alternately. Press “▲” or “ ” button to inquiry relevant parameters.
Step 3: Press “RETURN” button, it will enter the status of displaying fault acting value and delay time alternately again.
Step 4: Press “RETURN” button till “SEARCH” lamp is turned off, it will exit from inquiry status.
Test operation:
Step1: Confirm controller is in reset status. For H-type controller, it's necessary to confirm that key lock is at “SET” position.
Step2: Press “FUNCTION” button till “TEST” lamp flashes. Press “ENTER” button, and “TEST” lamp will be lit constantly. Press “ENTER”
button again, and circuit breaker will be switch-off, and display window of current meter displays acting time.
Step3: Press “RETURN” button till “TEST” lamp is turned off, it will exit from test status.
Inquiry method
Step 1: Confirm “T” lamp is turned on (It means there is some self-diagnosis information.)
And controller is under reset status.
Step 2: Press “CONFIRM” button, and display window of current meter displays error code.
Step 3: Press “CONFIRM” button again to confirm that self-diagnosis information has been reviewed (It will be eliminated automatically after
exiting for partial self-diagnosis information, such as rejection to actions, and E2PROM error, etc). Press “▲” and “ ” button to
check different codes one by one in circulation.
Step 4: Press “Return” button to exit from self-diagnosis inquiry status.
Communication:
When controller is at data receipt status, “Rx” lamp is turned on; when controller is at data sending status, “Tx” lamp is turned on.
