OP3 is the option for entering the password that is required for accessing OP4 through OP10. Service mode options OP4 through OP10 are password protected. This reduces the possibility of information being altered by mistake. Options OP1 and OP2 are for the viewing of information. Options OP1 and OP2 are not password protected. Password entry consists of actuating the scroll keys in the correct sequence. The password is identical for every GSC. The password cannot be changed. After the password is entered, the OP4 through OP10 options can be accessed. If a mistake is made during password entry, "FAIL" is briefly shown on the upper display. Pressing the "SELECT" key starts the password entry process again. Procedure To Enter The Password
Note: Service mode cannot be entered when the ECS is in the AUTO position.Note: Any active shutdown fault must be made inactive in order to access service mode. A FLASHING shutdown indicator means that a shutdown fault exists. To temporarily change a shutdown fault from an active shutdown fault to an inactive shutdown fault, turn the ECS to the OFF/RESET position. To permanently change a shutdown fault from an active shutdown fault to an inactive shutdown fault, the fault must not be occurring. Also, the ECS must be turned to the OFF/RESET position. If the jumper from terminal 6 to terminal 9 is not installed on the ECS, then the GSC will not power up in OFF/RESET and any active shutdown fault must be corrected before entering service mode.
