Possible Causes

Incorrect current limit configuration in firmware, Corrupted configuration memory, Factory calibration lost on main board

How to Fix / Troubleshooting

Safety first: Turn OFF the breaker before opening the unit. Do not attempt to modify hidden service menus unless instructed by Lectron.

  • 1. Restore defaults (if supported): Using the Lectron display or app, look for a factory reset or restore defaults option and perform it. Then power-cycle the unit.
  • 2. Check DIP switches or jumpers: Some Lectron models use internal DIP switches to set maximum current. With power OFF, verify that these are set according to the installation manual and match the circuit rating.

Resolution: If E17 persists, the calibration data in the main control board may be corrupted. Replacement of the main control board is typically required; contact Lectron support.
