Mount the reset switch in a location that complies with the warning in "Reset Switch Location" on page 25 . See " Initial Elec-
trical Connections " on page 35 for electrical connection.
Attach the required cordsets to the sensors, and route the sensor cables to the junction box, electrical panel, or other enclo-
sure 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 " Cordsets " on page 91 for selection of Banner supplied cables.
EZ-SCREEN SLS 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 pos-
sible.
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 SLS System. It is good wiring practice, and sometimes may be required
by code, to isolate emitter and receiver cables from high-voltage wires, avoid routing cables close to “noisy” wiring, and pro-
vide 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). In addi-
tion, QD cabling and any interconnect wires should meet the specifications in the following table:
0.5 A 0.75 A 1.0 A 1.25 A 1.5 A 1.75 A
18 AWG 114.3 m (375 ft) 76.2 m (250 ft) 57.3 m (188 ft) 45.1 m (148 ft) 38.1 m (125 ft) 33.2 m (109 ft)
20 AWG 73.1 m (240 ft) 48.8 m (160 ft) 36.6 m (120 ft) 30.0 m (95 ft) 24.4 m (80 ft) 21.3 m (70 ft)
22 AWG 45.7 m (150 ft) 30.5 m (100 ft) 22.9 m (75 ft) 18.0 m (59 ft) 15.2 m (50 ft) 13.4 m (44 ft)
NOTE: Maximum cable lengths are intended to ensure that adequate power is available to the EZ-
SCREEN System when the supply is operating at +24 V DC – 15%.
