Granville-Phillips 370 Stabil-Ion 370501-COA-T1 Ion Vacuum Controller

The Granville‑Phillips 370 Stabil‑Ion 370501‑COA‑T1 is a rack‑mounted ionization vacuum gauge controller that interfaces with the all‑metal 370 Stabil‑Ion Bayard‑Alpert gauges, providing calibrated pressure readouts via an on‑chip calibration system. Common failure points for this class of controllers include power supply degradation (especially the internal DC regulator), loss of signal from the gauge due to connector corrosion or broken gauge filament, and firmware corruption that can cause the display to freeze or show erroneous readings. First‑check steps: verify 115 VAC input voltage and monitor the controller’s output rails; inspect all cable connectors for tightness and signs of oxidation; review any error codes displayed on the panel or logged via the IEC‑488/USB interface before proceeding with component replacement.[oss-gpt-20b]
