## **EZA-TE Series Tubular Enclosures** 

_For EZ-SCREEN sensors mounted in washdown environments_ 

## **Features** 

- FDA-grade polycarbonate tubing and acetal end caps 

- Stainless steel mounting components 

- Brackets and fasteners included 

- Ideal for high-pressure washdown applications 

- NEMA 4X, IP67 

- 12 models available to accommodate EZ-SCREEN® sensors. 

Banner EZA-TE Series Tubular Enclosures are designed specifically for use with Banner EZ-SCREEN emitters and receivers. The enclosures are constructed of FDA-approved rugged polycarbonate tubing with FDA-approved acetal end caps. The enclosures are mounted with stainless steel mounting brackets and fasteners. The enclosures are available in 12 lengths. 

Use of the enclosure affects the sensing range of the sensor used: when used in pairs, range can be reduced by 50%. 

Figure 4 shows how the enclosure is assembled. Components are bagged together for easier assembly. 

**Figure 1. Assembled enclosure** 

**CAUTION... Reduced Sensing Range** Sensing Range is reduced 50% due to tubular construction. 

**WARNING... Maintain Required Separation** 

## **Distance** 

The light screen produced by the optical safety system sensors must be placed at a minimum safe distance from the dangerous motion of the machine being guarded. This necessary minimum distance is called the separation distance, and is discussed in Section 3 of the appropriate instruction manuals. Failure to calculate this distance correctly and to maintain minimum separation distance can result in serious injury.

**EZA-TE Series Tubular Enclosures** 

## **Adjacent Reflective Surfaces** 

A reflective surface located adjacent to the defined area may deflect one or more beams around an object in the defined area. In the worst case, an “optical short circuit” may occur, allowing an object to pass undetected through the defined area (see Figure 2). 

This reflective surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work  surface, the floor or the walls. Beams deflected by reflective surfaces are discovered by performing the trip test portion of the final alignment procedure and the periodic checkout procedures (Section 3.4.4 of the EZ-SCREEN Instruction Manual). 

## **To eliminate problem reflections:** 

- **If possible, relocate the sensors** to move the beams away from the reflective surface(s), being careful to maintain adequate separation distance (see Figure 2). 

**==> picture [50 x 38] intentionally omitted <==**

**WARNING . . . Avoid Installation Near Reflective Surfaces** 

Avoid locating the defined area near a reflective surface; it could reflect sensing beam(s) around an object or person within the defined area, and prevent its detection by the EZ-SCREEN System. Perform the trip test, as described in Section 3.4.4 of the EZ-SCREEN Instruction Manual, to detect such reflection(s) and the resultant optical short circuit. 

Failure to prevent reflection problems will result in incomplete guarding and could result in serious bodily injury or death. 

- **Otherwise, if possible, paint, mask or roughen** the shiny surface to reduce its reflectivity. 

- **Where these are not possible (as with a shiny workpiece)** , mount the sensors in such a way that the receiver’s field of view and/or the emitter’s spread of light are restricted. 

- **Repeat the trip test** to verify that these changes have eliminated the problem reflection(s). If the workpiece is especially reflective and comes close to the defined area, perform the trip test with the workpiece in place. 

**It is important to note** that using these tubular enclosures will increase (effectively double) the distance “d” shown in Figure 2. The curved surfaces increase the potential angle of the beams. Calculate the position of the emitter and receiver based on the formula shown in Figure 2 (in addition to the separation distance information presented in the EZ-SCREEN manual).
