DBC 130(F30i Series) DBC130ALE2A 1.3 2003 Power Circuit Overcurrent Detected 1) Description The circuit protector that is installed in the electric cabinet is tripped. 2) Cause of problem ① The circuit protector is triggered. (Abnormal signal is detected) ② An error in power control ③ The circuit protector has an error itself. 3) Action ① Find out the cause that the circuit protector is tripped. (ex) If QF22 is tripped, check the secondary circuit (L+) of QF22 if it's short-circuited, ② If the alarm occurs but no circuit protector is tripped, measure the resistance of each and take a necessary measure before turning the circuit protector back on.
contact point, and find out the defective circuit protector, and replace it with a new one. If you measure the resistance on the contact point of the circuit protector that is turned on, you will get "0" ohm if it's normal. ③ If you have found nothing wrong in steps ① and ② above, that is thought to be caused by the I/O circuit board. Check the I/O board and repair or replace it if necessary. Power Circuit Overcurrent Detected 7 Part Name Part No. Symbol Spec.
