Electrical Connections To The Guarded Machine; Ossd Output Connections - Banner EZ-SCREEN Instruction Manual

When the test piece is removed from the defined area, in trip output operation, the green Status indicator must
turn on (or flash green, if reduced resolution is enabled). In latch output operation, the Status indicator will remain
red until a manual reset is performed (the amber Reset indicator will be flashing).
WARNING: If Trip Test Indicates a Problem
If the EZ-SCREEN LP 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 defined area. Serious bodily injury or death could
result.
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).
6. If the EZ-SCREEN LP System passes all checks during the trip test, go on to
Machine on page 31.

4.4 Electrical Connections to the Guarded Machine

Verify that power has been removed from the EZ-SCREEN LP and the guarded machine. Make the permanent electrical
connections as described in
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 LP 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
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.

4.4.1 OSSD Output Connections

Both the Output Signal Switching Device (OSSD) outputs must be connected to the machine control so that the machine's
safety-related control system interrupts the circuit or power to the Machine Primary Control Element(s) (MPCE), resulting
in a non-hazardous condition.
Final Switching Devices (FSDs) typically accomplish this when the OSSDs go to an OFF state.
Refer to the output specifications in the Receiver Specifications (see
before making OSSD output connections and interfacing the EZ-SCREEN LP to the machine.
