6 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 is responsible for ensuring 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. Failure to follow these instructions could result in serious injury or death.
The following are the main steps to electrically install the EZ-SCREEN LS components and interface with the guarded
machine:
1. Routing cordsets and making initial electrical connections (see
on page 43).
2. Apply power to each emitter/receiver pair (see
Initial Electrical Connections
3. Perform an Initial Checkout Procedure (see
4. Make all electrical interface connections to the guarded machine (see
Electrical Connections to the Guarded
on page 50).
5. Perform a commissioning checkout procedure.
6.1 Routing Cordsets
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
on page 80 for selection of Banner supplied cables.
EZ-SCREEN LS 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 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 LS 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
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).
Installation/Replacement of RD Cordsets— To remove the Removable Disconnect (RD) cordset, unscrew the two Phillips
screws and carefully pull the connector straight back. To install an RD Cordset:
1. Slide the RD connector firmly into housing's RD port. (Ensure rectangular gasket is installed.)
2. Tighten the Phillips screws at base of connector to lock into place. Do not over tighten.
Note: The machine interface cable (e.g. RDLS-8xxD, DELSE-8xxD) must connect to the sensor end
adjacent to the indicators and serial number label for the system to operate properly.
