OPERATION 3.4 ELECTRONIC MONITORING AND CONTROL SYSTEM ECS SERVICE FUNCTIONS operated with KEY GROUP (D) and KEY SWITCH (C), illustration Z25237, continued Display of ”INPUTS-OUTPUTS”. This section is basically used for Testing procedures through authorized service staff and therefore locked dur- ing normal operation by the software program. Access to this section can be obtained in the Service section ”INPUTS-OUTPUTS ON/OFF” through actuation of key switch (C).
Messages ON/OFF The creation of Messages can be switched off, when for example, tests in the INPUT / OUTPUT levels are carried out with the ECS control functions operative (engines run- ning) and test conditioned messages shall not be dis- played (stored), i.e. Protocol and Statistics memory will not be filled with messages caused by testing operations. Evaluation ON/OFF. When commissioning or servicing the Shovel the data evaluation in the respective service function can be switched off with key switch (C). This prevents an over- writing of the selected function (Standard display, Inputs- Outputs or Service) by occurring messages, caused by repairs on the ECS system.
The function EVALUATION must only be switched OFF through authorized Service Staff. The instructions in the ECS Service Manual have to be observed. With the Evaluation switched OFF all monitoring and control functions of the ECS are inoperative.
