Troubleshooting and Maintenance
5.3 Test Mode
Opening a switch or relay contacts connected to the TEST1 and
TEST2 terminals of the emitter, or supplying a voltage of less
than 3V dc to TEST1 only, simulates a blocked condition, for
testing purposes .
To verify proper operation, measure the voltage between TEST1
(terminal 5) and dc COM (terminal 2 or 8) of the emitter:
• If the voltage is 10 to 30V dc, the emitter should be in Run
mode and beam scanning should be occurring. If not, check
the +24V dc (terminal 3) to verify proper supply voltage.
If the supply voltage is not within the rated supply voltage
specifications, correct the supply voltage and recheck emitter
operation. If the supply voltage is correct, TEST1 is 10 to 30V
dc and the emitter does not operate properly (Run mode with
beam scanning). Replace emitter.
• If the voltage is less than 3V dc, the emitter should be in Test
mode and no scanning should be occurring . If not in Test
mode, replace emitter.
5.4 Servicing and Maintenance
Cleaning
EZ-SCREEN System emitters and receivers are constructed of
aluminum with a yellow painted finish and are rated NEMA 4, 13
(IP65). Lens covers are acrylic. Emitters and receivers are best
cleaned using mild detergent or window cleaner and a soft cloth.
Avoid cleaners containing alcohol, as they may damage the
acrylic lens covers.
The accessory interface module is constructed of polycarbonate
and is rated NEMA 1 (IP20). It may be dusted, but avoid contact
with any liquids.
Warranty Service
The EZ-SCREEN System is designed for reliability. Do not
open the emitter or receiver housings, other than to access
the configuration port or to make terminal connections. Do not
open the housing of the interface module, if used. They contain
no field-replaceable components. If repair is necessary, do
not attempt to repair an emitter, receiver, or interface module
yourself; return the unit to the factory.
If it ever becomes necessary to return a system component to
the factory, please do the following:
1. Contact the Banner Factory Application Engineering group at
the address or numbers listed below:
Banner Engineering Corp.,
Application Engineering Group

They will attempt to troubleshoot the system from your
description of the problem . If they conclude that a
component is defective, they will issue an RMA (Return
Merchandise Authorization) number for your paperwork, and
give you the proper shipping address.
2. Pack the component(s) carefully. Damage which occurs
during return shipping is not covered by warranty.
