3A.4 COMPONENT REPLACEMENT
The relay board contains no replaceable circuit components, failure of the board requires replacement of the entire board. The only component that can be replaced is the nylon spacer.
3A.4.1 REPLACEMENT OF NYLON SPACERS
The replacement of nylon spacers fitted to the output board requires access to the non- component side of the PCB.
Note: Spacers will only be fitted on the output board if a second output board is to be fitted or has been fitted.
The spacers are secured in their holes by nut and nylon washer. To carry out a spacer replacement, the output board has to be removed from the input board. The procedure adopted is:
WARNING Mains voltages are present in this instrument when power is connected.
1.Isolate the 2468 electronic enclosure from the power supply.
2.Gain access to the PCBs and undo sufficient connections for the removal of the output board containing the defective spacer.
3.Remove the output board(s) by applying pressure to the upper
output board off its spacers and out of its Berg plug/socket connection.
4. Undo the nut and washer securing the faulty spacer and extract it from its hole, see inset diagram.
5. Fit the new spacer in position, align correctly on the board and secure firmly using the M4 nut and nylon washer.
6. Refit the PCB(s) into the enclosure,
