EZ-SCREEN LP
Instruction Manual Installation and Alignment
3.2.2 Mounting the Reset Switch
Mount the reset switch in a location that complies with the warning
in Section 3.1.3. See Figures 3-23 through 3-26 for electrical
connection.
3.2.3 Routing Cables
Attach the required cordsets to the sensors, and route the sensor
cables to the junction box, electrical panel, or other enclosure in
which the interface module, the redundant mechanically linked
interposing relays, FSDs, or other safety-related parts of the
control system are located. This must be done per local wiring
code for low-voltage dc control cables and may require installation
of electrical conduit. See Section 2.3 for selection of Banner-
supplied cables.
NOTE: The machine interface cable must connect to the sensor
end adjacent to the indicators, in order for the system to
operate properly.
EZ-SCREEN LP is designed and manufactured to be highly
resistant to electrical noise and to operate reliably in industrial
settings. However, extreme electrical noise may cause a random
Trip or Latch condition; in extreme cases, a Lockout is possible.

Emitter and receiver wiring is low voltage; routing the sensor
wires alongside power wires, motor/servo wires, or other high-
voltage wiring may inject noise into the EZ-SCREEN LP system.
It is good wiring practice (and may be required by code) to
isolate emitter and receiver cables from high-voltage wires,
avoid routing cables close to “noisy” wiring, and provide a good
connection to earth ground.
Sensor cabling and any interconnect wiring should have an
insulation temperature rating of at least 90°C (194°F).
Figure 3-12. RD cordset installation
Verify that:
• The emitter and receiver are directly opposite each other.
• Nothing is interrupting the defined area.
• The defined area (marked on the sensors) is the same distance
from a common reference plane for each sensor.
• The emitter and receiver are in the same plane and are level/
plumb and square to each other (vertical, horizontal, or inclined
at the same angle, and not tilted front-to-back or side-to-side).
Angled or Horizontal Installations – verify that:
• Distance X at the emitter and receiver are equal.
• Distance Y at the emitter and receiver are equal.
• Distance Z at the emitter and receiver are equal from parallel surfaces.
• Vertical face (i.e., the window) is level/plumb.
• Defined area is square. Check diagonal measurements if possible; see
Vertical Installations, at right.
Vertical Installations – verify that:
• Distance X at the emitter and receiver are equal.
• Both sensors are level/plumb (check both the
side and face).
• Defined area is square. Check diagonal measurements if
possible (Diagonal A = Diagonal B).
