MULTI-CHANNEL PROTECTION AND PREDICTIVE MAINTENANCE SYSTEM

The MOVISYS system is designed for the real-time multi-channel protection of machines. It consists of a 19”, 6U industrial rack.

Its modular structure allows for the connection of up to 52 transducers for real-time monitoring.

MOVISYS is compliant with the main specifications of standards API 670 and 678, ISO 2954 and 7919.

In addition to its protection function, MOVISYS can be coupled to a trending platform or a predictive maintenance platform.

General characteristics

  Presentation & capacity

• 19'' x 6 U rack
• Number of slots per racks: 13
• 4-channel protection module = 1 slot
• Maximum number of real-time channels per rack: 52 channels
• Module 4-channel bargraph visual display module = 3 slots

   Global functions

• Monitoring inhibition: 1 logical input per rack
• Alarm acknowledgement: 1 logical input per rack
• Trip multiply: 1 logical input per rack
• General power supply:  115/230V ac (optional 24Vdc or 48Vdc)

   Safety

• Each module has its own regulated power supply, so that a defective module does not affect the operating of the other modules.
• Permanent monitoring of the bias voltages
• Permanent monitoring of signal saturation
• Permanent monitoring of power supplies
• Internal self-tests: RAM, memory, PROM, watchdog
• Reinforced electromagnetic compatibility

Control and Communication Module: MAM

   Monitoring of the rack

• Centralisation of alarms
• 3 relays available: Prealarm, Alarm, Defect
• Self-control of power supply lines

   Communication

• 1 RS232 connection + 1 insulated RS485 connection
• Communication with MOVISET set-up software
• Communication with predictive maintenance software
• MODBUS communication with third system

4-channel protection module: MSVU

• Universal and fully parameterizable protection module
• Each channel can be configured separately

   Inputs:

• 4 channels: ICP accelerometer or velocimeter or proximity probe with individual current limited transducer power supply
• 1 tacho/sync channel for proximity probe or TTL signal
• 2 dc 0/10V input channels devoted to the collection of measurement conditions
• 1 24Vdc logcal input for trip multiply

   Outputs:

• 4 recorder dc outputs: 0-10V or 4-20 mA
• 4 bufferised ac outputs (terminal box on the rear panel)
• 4 bufferised ac outputs  (BNC on the front panel)
• 4 relay command outputs

   Calculation of monitoring indicators:

• Single or double integration
• Programmable filtering: band pass, narrow band, tracking filter
• Detection: RMS, peak or true or equivalent peak-to-peak
• Accelerometer-specific processing: 10-1000 Hz velocity according to ISO 2954, HF acceleration
• Proximity probe-specific processing: position (gap), pp vibration, Sppmax

   Visual display on the front panel for each channel:

• OK light: status of transducer connection
• Pre-alarm light
• Alarm light
• By-pass light: Inhibited channel, manually or automatically if detected as defective

   Alarms:

• 2 threshold levels per channel with validation delay
• Adjustable alarm logic: single-channel or dual-channel
• Command of relays in positive or negative logic, latching or non-latching.
