4 Electrical Installation and Testing
WARNING: Read this Section Carefully Before Installing the System
If all mounting, installation, interfacing, and checkout procedures are not followed properly, the Banner device
cannot provide the protection for which it was designed. The user has the responsibility to ensure that all local,
state, and national laws, rules, codes, or regulations relating to the installation and use of this control system in
any particular application are satisfied. Ensure that all legal requirements have been met and that all technical
installation and maintenance instructions contained in this manual are followed.
The user has the sole responsibility to ensure that this Banner device is installed and interfaced to the guarded
machine by Qualified Persons

, in accordance with this manual and applicable safety regulations.
The following are the main steps to electrically install the EZ-SCREEN Type 2 components and interface with the guarded machine:
1. Apply power to each emitter/receiver pair (see Initial Electrical Connections on page 23)
2. Perform and Initial Checkout Procedure (see Initial Checkout Procedure on page 25)
3. Make all electrical interface connections to the guarded machine (see Electrical Connections to the Guarded Machine on page
29)
4. Perform a commissioning checkout procedure (see Commissioning Checkout on page 41)
4.1 Routing Cordsets
Connect the QD connectors 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 Cordsets on
page 46 for selection of Banner-supplied cordsets.
The EZ-SCREEN Type 2 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 Type 2 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 QD cabling and any interconnect wiring should meet the following specifications. The wires used should have an insulation
temperature rating of at least 90 °C (194 °F).

Cable Size
Current Draw
0.5 A 0.75 A 1.0 A 1.25 A
0.823 mm2 (18 AWG) 375 ft 250 ft 188 ft 148 ft
0.518 mm2 (20 AWG) 240 ft 160 ft 120 ft 95 ft
0.326 mm2 (22 AWG)* 150 ft 100 ft 75 ft 59 ft
Note: Cable length includes power (+24 V dc) and return (0 V dc) wires at +25 °C, and is intended to ensure that adequate power
is available to the EZ-SCREEN Type 2 System when the supply is operating at +24 V dc - 10%.
4.2 Initial Electrical Connections
WARNING: Proper Electrical Hookup
Electrical hookup must be made by Qualified Personnel and must comply with NEC (National Electrical Code) and
local standards. Make no more connections to the EZ-SCREEN Type 2 System than are described in this manual.
Connection of other wiring or equipment to the EZ-SCREEN Type 2 System could result in serious bodily injury or
death.
Lockout/tagout procedures may be required (refer to OSHA1910.147, ANSI Z244-1, ISO 14118, or the appropriate standard for
controlling hazardous energy). Following relevant electrical standards and wiring codes, such as the NEC, NFPA79 or IEC60204-1, always
connect the earth ground (green/yellow wire). Do not operate the EZ-SCREEN Type 2 without an earth ground connection.
Make the electrical connections in the order described in this section. Do not remove end-caps; no internal connections are to be made.
All connections are made through the M12 Euro-style quick-disconnects.
