8.8.3 Monitoring Series-Connected Positive-Opening Safety
Switches
When monitoring two individually mounted safety switches (as shown in
Figure 30
on page 74), a faulty switch will be
detected if it fails to switch as the guard opens. In this case, the EZ-SCREEN de-energizes its OSSD output and disables its
reset function until the input requirements are met (i.e., the faulty switch is replaced). However, when a series of interlocking
safety switches is monitored by the EZ-SCREEN, the failure of one switch in the system may be masked or not detected at
all .
