  • Page 2 Section 3 — Common maintenance procedures Common maintenance procedures Once a 3500 Monitoring System is operating, it continuously measures and monitors a variety of supervisory parameters. The boards and components inside of 3500 modules cannot be repaired in the field and require no calibration. This section provides information for common tasks required under normal operating condititions.
