EPRO mms6823R displacement monitoring module

Description

The mms6823R card requires continuous data flow of connected MMS 6000 monitors over the RS485 bus system. Received data is converted via interface card to MODBUS RTU protocol over Ethernet TCP/IP. The respective characteristics, limits and states of individual modules are transmitted via Modbus RTU. Using MODBUS over TCP/IP characteristic values, limit values, module states as well as time functions are transmitted. This data is continuously available for the connected bus system. They can be archived and displayed in additional systems. The 6824 MMS card as well as connected MMS 6000 monitors can be configured via RS 232 on the front panel. RS 485 and MODBUS RTU buses are connected to a 48-pin connector on the back of the card. The TCP/IP network connector is located on the front of the card. TCP/IP connection is made by standard network cable and RJ45 connectors. The configuration can be done by the MMS 6910 configuration software, which is part of the “MMS para Kit” software package.

The MMS 6110 2-channel relative vibration monitor enables monitoring of relative vibrations of rotating parts of small and large turbines, compressors, gearboxes, fans, etc. using eddy current sensors. The sensor output signal (monitor input signal) represents the size of the air gap between the sensor face and the measured object. This signal contains a static component corresponding to the middle position of the rotor relative to the sensor, on which a dynamic component representing the dynamic movements of the rotor (vibration) is superimposed. MMS 6110 processes these components separately according to the specified configuration into standard output signals. Additional monitor circuits are used to guard the exceeding of the specified signal limits, supply the monitor and sensors and guard the fault-free status of the entire chain.

The core of the monitor is a microcomputer that allows configuration of various functional modes, parameters of sensors used, measuring ranges and all other necessary parameters. The monitor configuration as well as the reading of the measured data during the monitor revival and servicing is carried out either by a local PC with MMS 6000 configuration program via RS 232 (standard method) or remotely via LAN (if available). If the monitor has information about the machine speed (a phase mark signal is supplied), it also performs a harmonic order analysis and stores in the internal RAM the progress of the last start or run in the form of a Bode graph (vibration as a function of speed) and the progress of the speed change over time. These data and graphs can be viewed, for example, by the specified configuration program or other epro resources.
