1 Condition monitoring systems Vibration monitoring systems efector octavis is a simple to implement vibration monitoring system which detects vibration data and automatically determines the machine diagnosis directly on the machine. The machine condition is forwarded to the PLC or to SCADA systems. It fulfils the main requirements for modern machine monitoring: compatibility, modularity, and transferable configuration. System Description Online vibration diagnosis optimum price / performance ratio. Decentralised monitoring of plant and equipment integrated into the machine. Compact field units and modular control cabinet units. Digital and analogue alarm outputs. Standard data interface (OPC).

2 Vibration monitoring of machines and equipment according to ISO The electronic vibration monitor type VK monitors online the overall vibration condition of machines and equipment according to ISO The sensor measures the effective vibration velocity (rms) on a non-rotating machine surface. The unit is easy to set using 2 radial dials for quick adjustment of the switching point and response delay. The unit also has an analogue output. The vibration transmitter in stainless steel housing, type VT, transmits the values as an analogue signal (4 20 ma) directly to the PLC. APPLICATION OUTPUTS MEASURING RANGE Standard vibration characteristics / permanent machine protection 1x DC PNP + 1x analogue 4 20 ma Analogue 4 20 ma 0 25 mm/s 0 50 mm/s

3 Accessories The protective cover (order no. E30094) is slid onto the sensor and prevents unauthorised setting. To be on the safe side, the protective cover can also be sealed with lead. MOUNTING ACCESSORIES Protective covers Vibration diagnostic units g-monitor according to ISO10816 The compact vibration diagnostic units combine vibration monitoring, diagnostics and trending all in a small space. The integrated acceleration sensor measures permanently measures the machine vibration on non-rotating machine surface and calculates the ISOcharacteristics as well as frequency-selective diagnostic values. All the calculated characteristics are stored in a non-volatile internal memory. The freely adjustable storage intervalls enble the customer to use the trending function according to his requirements. The unit is easy to set up using a PC-software.

5 Cabinet modules for vibration diagnosis The product type VSE offers all possibilities for an integrated complete machine diagnosis from an automatic frequency-selective diagnostic measurement to integrated trending with a time stamp. The diagnostic electronic can continually analyse and evaluate simultaneously up to 4 points of measurement as well as 2 further processe values. Switching outputs signal early and main alarm. Trending can be shown using the analogue output. In addition 12 counters can be configured and monitored using alarm limits. The ethernet interface can also be used to integrate the decentralized diagnosis in higher level systems.

6 Accessories The decentralised diagnostics can be integrated into higher-level systems via the Ethernet interface using the cross-over patch cable. The software ensures complete machine diagnosis. CONNECTION TECHNOLOGY Cross-over cable SOFTWARE Parameter setting software for efector octavis OPC server software Vibration sensors for connection to external diagnostic electronics VSE The vibration sensors are used to detect measurement data specifically in connection with the octavis diagnostic electronics type VSE. The compact and highly robust design, based on MEMS technology, provides good long-term stability even under adverse environmental conditions and no false signals due to crushed cable. The integrated self-test ensures trouble-free machine monitoring. Using standard cables ensures simple integration in the existing infrastructure.
