External Device Monitoring (EDM)
This feature allows the EZ-SCREEN Type 2 system to monitor the status of external devices such as MPCEs. The EDM used in this
system is similar to Power Monitoring employed by MINI-SCREEN safety light screens. A normally closed and a normally open contact
from each monitored device are wired in series-parallel to detect if one of the devices fails.
Status Indicators
