What to do if the red LED flashes 3x with 3 acoustic warning signals on my Klauke EK 425-L?

If the red LED flashes three times accompanied by three acoustic warning signals, it indicates a serious fault. If this occurs repeatedly, return the unit to an Authorized Service Center (ASC). Do not attempt to open the tool or damage its seal. If it happens only once, try crimping the connector a second time.
