ESSER FlexES: Loop is too long or attenuation too high

ESSER FlexES·0 views·0 field notes

What This Code Means

Signal strength is too low due to excessive loop length or high cable resistance.

Common Causes

  • 1Loop length exceeds maximum limits
  • 2Incorrect cable type used (e.g., non-IBM or non-transmission cable)
  • 3High resistance connections

Resolution Steps

Verify loop length and resistance (max 70-100 ohms/km depending on cable); reduce length or upgrade cable if necessary.
