ScreenMaster RVG200

Paperless recorder

Terminal block failures

1 Introduction

There have been instances reported where some or

all inputs on an RVG200 analog input card have

shown as failed immediately after installation, with

no apparent cause for the failure. In rare cases, this

can be attributed to a faulty analog input card but

the most common cause has been identified as a

problem affecting the connection strips within the

terminal block assembly.

The reason for potential failure is that during

installation, unscrewing the terminal connection,

inserting the wire and tightening the screw can

cause the spring assembly inside the terminal block

to move, breaking its contact with the PCB.
