  If the power supply indicator (L1, L2 & L3 LED) on your SEP Measuring Instruments isn't lighting up, begin by checking the switch, circuit-breaker, fuse, and thermal cut-off. Ensure the terminal screws on L1, L2, L3, and N are correctly installed and tightened. Verify a 230V 50Hz AC voltage between the terminal screws on N and L1, L2, or L3 when the power supply is input. Also, check the terminal screws on 25, 24, 23, 22, 21, and 20, ensuring they are fixed. Confirm a 230V 50Hz AC voltage between terminal screws N and 24, 22, or 20 when the power supply is input. If issues persist, it may be necessary to replace the meter.

  If the register on your SEP Measuring Instruments isn’t running, first check if the power supply indicator (L1, L2 & L3 LED) is lit. If the operating power is too low, the spacing interval of running will be prolonged so that people is under the delusion that register can’t run. If problems continue, it may be necessary to replace the meter.

  If there is no pulse output from your SEP Measuring Instruments, verify that the external voltage source (Ui) is 5-27V DC. Ensure correct connection by connecting 5-27V DC to connector 26 (anode) and the signal wire (S) to connector 27 (cathode).

Why is the consumption indicator light off on my SEP LEM022SJ Measuring Instruments?
- D
  David HallAug 18, 2025
  The consumption indicator (PULSE LED) on your SEP Measuring Instruments will only flash when a load is running. If the operating power is too low, the spacing interval of flashing will be prolonged so that people is under the delusion that LED isn’t burning. If the problem persists, it may be necessary to replace the meter.
