WARNING: If the Trip Test Indicates a Problem
If the EZ-SCREEN LS Basic 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 39).

6.4 Electrical Connections to the Guarded Machine
Verify that power has been removed from the EZ-SCREEN LS Basic and the guarded machine. Make the permanent
electrical connections as described in
on page
40 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 Basic must also
have been aligned and passed the Initial Checkout, as described in
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 Basic to the machine.
