Core Features & Operating Capabilities
- Real-Time Parameter Indication: Continuously displays overall vibration levels, axial position, shaft speed, differential expansion, and temperature measurements across all active 3500 monitor modules.
- Instant Alarm & Status Visibility: Provides clear visual indicators for system OK status, Alert/Danger alarm conditions, Not OK states, and active channel bypasses.
- Flexible Mounting Configurations: Can be mounted directly on the front face of a 3500 chassis frame, panel-mounted on a control cabinet door, or mounted in a remote equipment room.
- Independent Operation: Operates independently of external host software or network servers, ensuring local operators always have direct access to machinery safety data.
- Structured Menu Navigation: Allows technicians to easily scroll through individual racks, slots, and channels to view first-out alarm events and system event logs.
