Linde 580 2451 Controller
 |
The Linde 580 2451 Controller is a PID temperature control unit (SWA‑2451B) that outputs a pulsed 12 V DC signal to an SSR via terminals 9 and 10. Common failures on this class of controllers include burnt or tripped SSR drivers, degraded MOSFETs in the power stage, and capacitor leakage in the input filter. Check the supply voltage and continuity to the SSR driver; verify the output pulse waveform with a scope; inspect for burn marks or swollen electrolytics on the board. If the controller shows error codes, review the diagnostic register and reset sequence per the manual.[oss-gpt-20b] |
