If all Alignment indicators turn green or fail to follow the position of the test piece while it is within the defined area,
the installation has failed the trip test. Check for correct sensor orientation and reflective surfaces.
When the test piece is removed from the defined area, in trip output operation, the green Status indicator must turn
on .
WARNING: If the Trip Test Indicates a Problem
If the EZ-SCREEN LS System does not respond properly to the trip test, do not attempt to use
the System. If this occurs, the System cannot be relied on to stop dangerous machine motion
when a person or object enters the sensing field. Failure to follow these instructions could result
in serious injury or death.
5. If mirrors are used in the application: Test the defined area on each leg of the sensing path (for example, emitter to
mirror, between mirror and receiver, see
on page 50).

6. If the EZ-SCREEN LS System passes all checks during the trip test, go on to
Electrical Connections to the Guarded
on page 50.
6.4 Electrical Connections to the Guarded Machine
Verify that power has been removed from the EZ-SCREEN LS and the guarded machine. Make the permanent electrical
on page 51 as
required by each individual application.
Lockout/tagout procedures may be required (refer to OSHA 1910.147, ANSI Z244-1, ISO 14118, or the appropriate
standard for controlling hazardous energy). Follow relevant electrical standards and wiring codes, such as the NEC,
NFPA79 or IEC 60204-1.
Supply power and external device monitoring (EDM) should already be connected. The EZ-SCREEN LS must also have
been aligned and passed the Initial Checkout, as described in
on page 43.
The final connections to be made or verified are:
• OSSD outputs
• FSD interfacing
• MPCE/EDM
• Fault Output
• Scan Code Select
CAUTION: Shock Hazard
Always disconnect power from the Banner device and the guarded machine before making any
connections or replacing any component. Use extreme caution to avoid electrical shock at all times.
6.4.1 OSSD Output Connections
Refer to the output specifications in the Receiver Specifications and these warnings before making OSSD output
connections and interfacing the EZ-SCREEN LS to the machine.
