Professional diagnostic and board-level repair service for this Flygt 835840 alarm control.

The Flygt 835840 is a 24 V AC monitoring‑relay control and status unit used in pump station automation and wastewater treatment systems. Common failure modes for this class of relay assemblies include coil burnout, contact wear or pitting, and insulation degradation between the input and output terminals. First‑check diagnostics: verify that the 24 VAC supply is present and within spec; inspect the relay contacts visually for corrosion or mechanical damage; and review any error codes or status LEDs on the unit to confirm whether the alarm condition is being triggered by a fault in the coil, load, or external control logic.
