广日gvp-2（Guang RI gvp-2） Guang RI GVP2 fault code and processing default classification 2009-12-28 11:10:42 read 86 comment 0: large and medium subscriptions Elevator logic all possible faults, fault code display range of E041 ~ E112 E041 (primary microcomputer or frequency conversion microcomputer detected the main microcomputer can not be recovered from hardware and software faults) Causes: Software - bus errors, address errors, interrupt stack exceptions, system programs, and number exceptions Hardware - detects RESET signals, BERR signals, and HALT signals Processing: disconnecting all outputs; blocking the inverter output; saving the current fault status. Disable the execution of all applications, executing only programs in the operating system section. The fault status is locked before power failure and can not be reset automatically E042 (main microcomputer detects the fault of frequency conversion microcomputer) Reason: the normal mark of software frequency conversion microcomputer in double port RAM is more than 80 ms without change Hardware - frequency microcomputer hardware fault signal output Handle: ditto; E043 (safety relay on control panel, short connection fault) Reason: the safety loop is switched off or the drive output of the safety relay on the control board is disconnected, but the contact of the relay on the control panel has not been disconnected, and the time lasts for more than 0.2 seconds Handle: ditto; E044 (safety relay on the control panel is disconnected) Reason: the safety loop is switched on and the drive output of the safety relay on the control board is switched on, but the contact of the relay on the control panel is not closed and the time is longer than 0.2 seconds Handle: ditto; E045 (running contactor short connection fault) Reason: the drive output of the contactor is disconnected, but the auxiliary contact input of the running contactor is still connected and the time lasts for more than 0.5 seconds Handle: ditto; E046 (brake
