    NO: Continue to step 5. 4. Does the fault remain after changing the sensor? YES: The fault may be in the analogue input section of the IMx-W unit. Contact SKF Condition Monitoring Center Luleå for service and further information. NO: Sensor fault. The sensor is defective and must be replaced.
  • Page 69 Component Check 7. Is the sensor a standard type? YES: These are powered internally from the IMx-W unit. If the IMx-W unit does not supply open circuit voltage with input open, then the IMx-W input is probably damaged, or the input is not configured to supply a power feed to the sensor.
  • Page 70 6. Cable is probably damaged. However, first try disconnecting one of the poles on the cable from the IMx-W terminal block. If the voltage is Ok, then the fault is in the IMx-W unit input stage. Otherwise, the cable is damaged and needs to be repaired.
  • Page 71 3. Is there an expected speed signal on the IMx-W terminal block? YES: The signal can be too weak or at too high impedance for the IMx-W speed input to be triggered. Sufficient voltage ripple (peak to peak) is shown in the electrical specifications.
