Trip Output Operation: The Status Blocked indicator must turn ON Red and remain ON for as long as the test piece
remains in the defined area (and the Status Clear indicator OFF during the same time). If not, the installation has failed
the trip test. When the test piece is removed from the defined area, the Status Clear indicator must turn ON Green and
the Status Blocked indicator must go OFF.
•
Latch Output Operation: The Status Blocked indicator must turn ON Red and remain ON for as long as the test piece
remains in the defined area (and the Status Clear indicator OFF during the same time). Both Yellow indicators must
remain ON steady, unless the top or bottom beam is blocked. If the top (synch) beam is blocked, both Alignment
indicators will go OFF.
If the Yellow Alignment indicators begin to flash at any time while the test piece is interrupting the defined area, the
installation has failed the trip test. Check for correct sensor orientation and reflective surfaces. Do not continue until
the situation is corrected. In Latch Output Operation, the Status Blocked indicator will remain ON until a manual reset
is performed (both Yellow Alignment indicators will be flashing).
WARNING: If Trip Test Indicates a Problem
If the EZ-SCREEN Type 2 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, see
6. If the EZ-SCREEN Type 2 System passes all checks during the trip test, go on to
on page 29.
4.4 Electrical Connections to the Guarded Machine
Verify that power has been removed from the EZ-SCREEN Type 2 and the guarded machine. Make the permanent electrical connections
as described in
OSSD Output Connections
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 the external reset switch should already be connected. The EZ-SCREEN Type 2 must also have been aligned and
passed the Initial Checkout, as described in
The final connections to be made are:
•
OSSD outputs
•
FSD interfacing
•
MPCE/EDM
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
