    7 MAINTENANCE 7.1 Maintenance Inspection To use the S10mini or S10V in an optimum condition, check the items listed below. Make this check at routine inspection or periodic inspection (twice or more per year). (1) Module appearance Check that no fissure or crack exists in the module case. If the case has such a damage, there is a possibility that the internal circuit may also be damaged, resulting in a system malfunction.

    ③ Connect the personal computer and the LPU module together with the RS-232C cable. ④ Start Hitachi’s S10V ET.NET System and make a hand-written record of the currently used IP address. (If the existing parameters are not accessible for some reason, use the copies of their set values [item ④] that were obtained in preparation.)

    7 MAINTENANCE 7.2 Troubleshooting 7.2.1 Procedure Trouble occurred. Check the trouble according to “7.2.2 Trouble detection and solution.” Is each item executed correctly? Correct if the item is not executed correctly. Returned normally? Check the error LED, CPU display (S10mini), error code (S10V), and take a necessary action.
  • Page 107 Check that a cable with shielded ground wire is used as the transceiver cable. (2) Are the modules mounted correctly? Check that the SV.LINK module is left-justified with no idle slot between the modules. Check that no set screws loosen.
  • Page 108 7 MAINTENANCE (3) Is grounding correctly? Do not ground the SV.LINK module in the same place where high-voltage equipment is grounded. They must be grounded in separate places. Perform grounding work conforming to Class D grounding or higher. (4) Are LG and FG separated?

    7.3 Errors and Actions To Be Taken 7.3.1 CPU LED display messages In the S10mini, when an event or error occurs in the SV.LINK module, the corresponding message shown in the following table is displayed on the indicator of the CPU module. The contents of display are classified by main setting and sub setting of the SV.LINK module.
  • Page 110 CPU module in the S10mini. In the S10V, the error codes shown in the following table are displayed by selecting the error log from the tool system. And the error LED comes on and error freeze information is collected. The SV.LINK module operation is stopped.
  • Page 111 If the SV.LINK module detects a hardware error, the error LED lights and error freeze information is registered, and the operation of the SV.LINK module stops. If an error having a number between 11 and 19 in the following table occurs, only the error code is registered in the freeze information area and the value 0 is entered in all the other areas.
