HITACHI LUD700A Communication module

a. Change the setting of S1 on the I/O module to match the I/O module address set in its configuration. Table 3-1 explains how to set the FEC address. - or - b. Modify the I/O module address in the control module configuration (function code 132) to match the I/O module address set by S1. Refer to the Function Code Application Manual and Operator Interface Station instructions for information about changing the control module configuration. 2. Verify that the I/O module and its control module reside on the same I/O expander bus. There must be a 24-pin dipshunt (all pins intact) installed in all dipshunt sockets of the MMU between the FEC module and its control module.The green status LED on the IMFEC1
module blinks every ten seconds if the module has a hardware failure. To correct a hardware failure, replace the FEC module.

EDGE CONNECTOR PIN ASSIGNMENTS 

Edge connector pin assignments (P1, P2 and P3) are listed in Tables 5-3 through 5-5. The pin assignments for J1 (connector for the LCD diagnostic display) are in Table 5-6.The reliability of any stand-alone product or control system is affected by the maintenance of the equipment. Elsag Bailey recommends that all equipment users practice a preventive maintenance program that will keep the equipment operating at an optimum level. This section presents procedures that can be performed on-site. These preventive maintenance procedures should be used as guidelines to assist in establishing good preventive maintenance practices. Select the minimum steps required to meet the needs of your system.

PREVENTIVE MAINTENANCE SCHEDULE 

Table 6-1 is the preventive maintenance schedule for the FEC module. The table lists the preventive maintenance tasks in groups according to their specified maintenance interval. Some tasks in Table 6-1 are self explanatory. Instructions for tasks that require further explanation are covered under PREVENTIVE MAINTENANCE PROCEDURES. NOTE: The preventive maintenance schedule is for general purposes only. Your application may require special attention. Personnel performing preventive maintenance should meet the following qualifications. • Should be qualified electrical technicians or engineers that know the proper use of test equipment. • Should be familiar with the IMFEC1
module and the INFI 90 OPEN system, have experience working with process control systems, and know what precautions to take when working on live AC systems.
