0025 00 TM 1-6625-724-13&P 0025 00-18 Table 1. Error Reported on CADU Error Screen (cont.) Code # Message 4148: Accelerometer Failure on Input 4 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4149: Accelerometer Failure on Input 5 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4150: Accelerometer Failure on Input 6 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status In Manager Menu) 4151: Accelerometer Failure on Input 7 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4152: Accelerometer Failure on Input 8 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4153: Accelerometer Failure on Input 9 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4154: Accelerometer Failure on Input 10 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4155: Accelerometer Failure on Input 11 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4156: Accelerometer Failure on Input 12 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4157: Accelerometer Failure on Input 13 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4158: Accelerometer Failure on Input 14 ACTION: (1) Check cable (2) Check accelerometer (3) Verify SETUP (also go to Setup/Status in Manager Menu) 4159: Tachometer Failure on PIT Timer ACTION: (1) Power the DAU off and on (2) Wait 20 seconds, make a measurement Internal software fault. Power the DAU off and on, and then try to make a measurement. If the failure persists, send unit to TMDE for repair. 4160: Tachometer Failure on Input 1 ACTION: (1) Verify connection (2) Verify gap or Check tape for optical Interrupter (3) Check cable The DAU is receiving no timing pulses from the external magnetic or optical tachometer. Verify the following: 1. Interrupter is connected to the correct channel. 2. Interrupter is gapped properly and working. 3. Optical interrupter is aimed at the reflective tape. 4. Correct cable is installed and working. Repeat measurements, as necessary. This is a common problem caused by improper sensor connection to the DAU.
