EZ-SCREEN LP
Instruction Manual
Cascadeable EZ-SCREEN
The Remote Fixed Blanking feature can be used on an
EZ-SCREEN LP cascade receiver as a stand-alone system
or as the end (slave) unit in a cascaded system. The remote
programming is only effective on that receiver. If fixed blanking
is required on other receivers in the cascade string, see Section
3.4.3 for DIP switch configuration information.
Programming Key Switch Location
The EZA-RBK-1 or an SPDT (Form C) switch is required to
perform the remote programming procedure, as shown in Figure
7-12. In addition, a normally open (N.O.) reset switch, such
as the EZA-RR-1, is generally recommended and is required
for systems configured for Latch output. A key-actuated switch
provides some supervisory control since the key can be removed
from the switch (see Section 3.1.3).
The Programming Key Switch must be:
• Located outside the guarded area,
• Located to allow the switch operator full unobstructed view of
the entire defined area, and
• Protected against unauthorized or inadvertent operation.
WARNING . . .
Use of Reduced Resolution
and Fixed Blanking
Use Reduced Resolution and Fixed Blanking only when
necessary. Any holes created in the defined area either must be
completely filled by the blanked object or the safety (minimum)
distance must be increased to account for the larger resolution (see
Section 3.1.1).

7.10 Remote Fixed Blanking
As described in Sections 1.4.9 and 3.4.3, fixed blanking is
available to, in effect, “disable” beams that would otherwise be
continually blocked by a stationary object. One or multiple areas
within an EZ-SCREEN LP sensor pair may be “blanked out,”
with a minimum of one beam between two blanked areas. The
first sensing beam (synchronization beam) at the display end of
sensor must remain clear (can not be blanked); any other beam
may be blanked. All beams of a fixed blanked area must remain
blocked during operation in order for the OSSDs to remain ON.
On initial installations of cascadeable emitter/receiver pairs, when
they are used as a standalone system, the cascade configuration
procedure is not necessary.
