[HX-TEDO-250209-001] Manifold Pressure Monitoring System Manual R2

Overview

The Manifold Pressure Monitoring System (MPMS) is designed for real-time pressure monitoring of manifold lines in industrial applications. The system provides alarm notifications, data logging, and remote communication via RS-485. It consists of pressure transmitters, an embedded PC, A/D converters, intrinsically safe barriers, and a printer.

5. Troubleshooting Guide (p.34-38)

Issue	Cause	Solution
No power indication	Faulty fuse or wiring	Replace fuse, check wiring
No alarm activation	Sensor wiring issue	Check wiring & perform self-test
False alarms	Electrical interference	Check grounding and shielding
No data recording	Database full	Delete old logs and restart

6. Storage & Maintenance (p.6)

Keep dry and avoid moisture exposure.
Inspect cables and connectors periodically.
Backup log files every three months.
