5.1
Overview
This section provides information about preventive maintenance and replacing damaged parts. The
topics covered in this section are:
•
Replacement of damaged parts such as the Remote Indicator printed wiring assembly (PWA)
modules.
5.2
Preventive Maintenance Practices and Schedules
The RMA801 Remote Indicator does not require any specific maintenance at regularly scheduled
intervals.
Maintenance of the RMA801 is limited to ensuring that connections, seals and mounting are tight and
secure. There are no moving parts or adjustments and hence no reason to open the field housing except
to inspect for corrosion or conductive dust entry which could later affect reliable operation. The Remote
Indicator component modules themselves should never be opened.
5.3
Replacing the Local Display and Communication Electronic
Assembly
The Communication module includes a connector to the Display Module. This section includes the
procedure to replace the Communication module.
Refer to Figure 17 for parts locations.
