Important messages, instructions and information in this manual must be followed carefully. Otherwise, harm might occur to equipment and/or personnel. IMx-M shall be used for speed alarming only. It shall not be used to protect/trip machine on overspeed. IMx-M does not fulfill the requirements related to overspeed protection.
Page 6 Be sure to read "Signal Grounding" and "Signal Isolation" chapters thoroughly and understand them. • SKF USB isolator cables must always be used when connecting to IMx-M USB ports. • Equipment connected to buffered outputs must be isolated from the protective earth.
Page 7 Caution to a possible hazard due to mains power double pole/neutral fusing. An IMx-M rack must be situated in a cabinet with a metal bottom or plastic bottom with flammability classification of at least V-1. The cabinet must fulfill at least IP 20.
Page 8 DIP switch settings must be handled with a special care to prevent any damage to the IMx-M rack: • Do NOT change DIP switch settings while the IMx-M rack is powered-up, as this may cause damage and void warranty. •...

Page 69: Imx-M Manager
For the physical installation, each protection module must be paired with a condition monitoring module to form a CMM + PRM pair. In the IMx-M Manager a slot consists of the configurations for the CMM + PRM pair. From the IMx-M Manager's configuration point of view, configuring a “slot” means configuring the CMM network settings, a PRM and an associated RLM.
Page 70 Protection IMx-M Manager Figure 2 - 34. IMx-M Manager Configuration Overview. For a fully equipped IMx-M rack, the configuration file of each slot contains the following: • Slot 1: the configurations of CMM 1, PRM 1 and RLM 1 •...

Page 91 • Perform Save. Export to Excel File The IMx-M Manager allows configurations to be exported as a Microsoft Excel Workbook from plant, area, rack and slot nodes. These workbook configurations can used as reference. One of advantages of this feature is that it allows these levels of the configuration to be exported in a readable format for reference and use by external bodies.

This dialog shows a representation of an empty IMx-M rack with two power supply units fitted and fault detections enabled. Rack Name The first task is to assign a name to this rack. Given that each rack is a physical item mounted in a geographical area, the name chosen should always be an easier reference for future use (E.g.

Mount the IMx-M rack and make sure that it is firmly attached.
Page 207 IMx-M is designed to operate in a maximum temperature of 65 °C / 149 °F. However, operating IMx-M at this temperature shall be avoided as it will drastically shorten the lifetime of all components.

Page 209 Hardware Installation Figure 4 - 3. Illustration of Desired Diverted Airflow. One fan tray and an air guide plate shall be mounted for each IMx-M rack: • The fan tray must be mounted directly below each IMx-M rack. • The air guide plate must be mounted directly above each IMx-M rack.
Page 210 Cable type shall have a flammability rating VW-1, FT-1 or fulfill the requirements according to IEC 60332-1-2 or IEC 60332-2-2. It is required that the IMx-M rack must be connected to protective ground/earth (PE). Refer to Mains Power for attaching power cable to the mains power/power grid.

Page 214 Important - For the permanently connected IMx-M rack, an external all pole power switch must be installed to be able to disconnect the IMx-M rack from the mains power grid. The switch must be labeled "IMx-M” or similar. On/off position must be clearly marked.
Page 215 (power connectors AC1 and AC2) must be disconnected before maintenance. Power Supply There are two power supply units for an IMx-M rack. Each power supply unit can individually power a fully equipped rack. Important - Power supply unit revision 3 or below cannot be combined with power supply unit revision 4 or above.

Page 226 Hardware Hardware Configuration Front Panel BNC Buffered Outputs In addition to the back side buffered outputs, IMx-M offers a feature where a user can select up to three channels to be directed to BNC connectors for buffered outputs. These BNC connectors (2 for analog buffered outputs and 1 for digital buffered output) are located on the front panel of protection module, as shown in Protection Module (PRM)Protection Module (PRM).
Page 227 Each 4–20 mA Output is updated every 640 ms. The values are related to the scale setup in 4-20 mA Outputs configuration via IMx-M Manager. 4 mA will correspond to the minimum scale value and 20 mA to the maximum scale value with a linear scaling between those values.

Hardware Hardware Maintenance Hardware Maintenance The IMx-M hardware, for example the IMx-M rack, is virtually maintenance free. However, we advise the customers to make an annual inspection of the equipment. Maintenance of Sensors Visual inspections for looseness or any physical damage on sensors, sensor cables and connectors shall be conducted on regular basis, such as annually.

Troubleshooting Guide Troubleshooting Guide is intended as an aid when IMx-M system is not functioning correctly. It is designed for instrumentation engineers and others with sufficient knowledge of electrical troubleshooting in electronic systems with a 230 V/110 V power supply and of the risks that this can mean in case of incorrect procedure.

2. Measure the DC voltage between the sensor wires on the IMx-M terminal block using a digital voltmeter. See the table below for the normal voltage values with and without a connected sensor respectively.
Page 254 NO: Continue to step 5. 4. Does the fault remain after changing the sensor? YES: The fault may be in the analog input section of the IMx-M rack. Contact SKF Condition Monitoring Center Luleå for service and further information. NO: Sensor fault. The sensor is defective and must be replaced.
Page 255 6. Cable is probably damaged. However, first try disconnecting one of the poles on the cable from the IMx-M terminal block. If the voltage is OK, then the fault is in the IMx-M rack input stage. Otherwise, the cable is damaged and needs to be repaired.
Page 256 3. Is there an expected speed signal on the IMx-M terminal block? YES: The signal can be too weak or at too high impedance for the IMx-M speed input to be triggered. Sufficient voltage ripple (peak to peak) is shown in the electrical specifications.
