CODE: EX281c码:ex281c SHORTMESSG: PREP_TIMER_ERR 预备_定时器_犯错DETAILED DESCRIPTION: 详细说明-The anode rotation() has failed to reach 46 Hz in 1.5 seconds. 阳极自转未能达到46赫兹1。5秒Reason for error: 错误的原因- Blown fuse at XRS chassis. 烧断熔丝在球壳- ANODE ROTATION BOARD D23 defective（）. 阳极自转板d23缺陷- Optica（ ）l fibres between the stator（ ） and TANK( ) BOARD defective. 光纤在之间定子和坦克板缺陷- TANK BOARD defective.- CONTROL BOARD D27 defective. 控制板d27缺陷- ROTANX defective.What to do? 怎么办？-1: Check voltages coming from DC1, DC2, (see ACS_Manual, XRS- measurement points).2: Check the fuses F24-F26 on the XRS chassis.3: Check the red LED V16 or V14, on the ROTATION CONTROL BOARD D23.4: Check the LED ACC (V4 or V26) during INIT or test. Should light approx. 1.5sec.5: LED ACC (V4 or V26) do not light during acceleration; - Check cable between the CONTROL BOARD D27 and the ROTATION CONTROL BOARD (D23/D7) X232 - X233. - Check cable between X224-X225. - Replace CONTROL BOARD D27. - Replace ROTATION CONTROL BOARD D23.6: Check the 400 VAC supply to the stator during anode rotation, test points L1, L2 and L3 on the ROTATION CONTROL BOARD D23. The supply voltage is only for 1.5 sec available. Is the supply faulty change ROTATION CONTROL BOARD D23.7: Check the cable between the ROTATION CONTROL BOARD D23 and the ROTANX, X216 -X217.8: Is the anode disk rotating (listen to the single tank) and also the supply of 3-phase 400 VAC okey, check the feedback to the CONTROL BOARD D27.9: Remove the transmitter (grey), and check if the transmitter emits red light (high intensity). If it does not, replace the TANK BOARD.10: Measure on the test point ROT_FR on the TANK BOARD. If no signal is found, replace the TANK BOARD.11:Replace ROTANX12:Measure on the test point ROT_FR on the TANK BOARD.
