Manual › AccTRANS 9. RAMS properties MTBF 1 Failure rate calculated as the total sum of the failure rates of each component, with respect to operating temperature conditions. 10. Handling instructions 10.1. Assembly The accelerometer AccTRANS is supposed to be mounted in the vicinity of the wheel axles in the outskirt area of the train. The housing of the sensor is designed as a flange with four holes for M5 screws (see subsequent drawing). Ground connection screw hole, threaded (M5) Hole for mounting screws / bolts Mounting on given M4 thread rods Mounting with M4 bolts Align the device by...

Manual › AccTRANS 10.2. Maintenance The device is developed in a way that no maintenance actions are required during its lifetime. 10.3. Disassembly 1. Disconnect the sensor’s cable from the train’s connector. 2. Unscrew bolt in grounding screw hole and remove grounding cable. 3. Loosen either the four bolts or the nuts with which the device has been attached and lift off the sensor. 11. Troubleshooting Basically two kinds of errors can occur, electrical and mechanical ones. One cause of a remediable mechanical error could be improper connection of the sensor, e.g. by contaminated connector...
