## Overview 

The Series BMHE Heated Enclosure is designed to offer weather protection for a MINI-ARRAY emitter or receiver in an outdoor application such as a toll booth. 

The Enclosure has a laminated safety glass window with a series of resistance wires. The resistance wires connect through two thermostats to a power source to heat the glass as necessary to prevent condensation, ice or snow from inhibiting the beams. When humidity inside the enclosure rises, a humidistat prompts the heater to warm the window, to prevent condensation. 

The Series BMHE MINI-ARRAY Heated Enclosure is designed to accommodate MINI-ARRAY emitters and receivers 4 ft, 5 ft, or 6 ft long, with enough extra space at top and bottom to ensure accurate mounting. 

1 Standard color is Federal Safety Yellow (Federal Standard color# 23538). Consult Factory for other colors.

## Assemble the Heated Enclosure 

Follow these instructions to assemble the heated enclosure.

**==> picture [79 x 229] intentionally omitted <==**

1. Prepare a 6 in × 6 in square mounting pad, using four 3/8" studs (not included). 

2. Mount the base plate to the housing with four stainless steel flat head screws (1/4" - 20 x 3/4", included). 

3. Feed the heater cable and the sensor cable through the cutout in the base plate; set the housing/base plate assembly onto the mounting pad. 

4. Level the housing in one of two ways: 

   - Use three user-supplied 3/8" - 24 x 2" bolts and lock nuts; or 

   - Use four leveling nuts, threaded onto the four mounting studs, under the base plate. After leveling, secure the housing assembly using four 3/8" nuts on the four mounting studs. Add flat washers and lock washers, as required (not included). 

## Wire the Enclosure 

Follow these instructions to make the electrical connections. 

1. Connect the heater supply cable. The heated window is powered at the top of the enclosure. Transformer Power Supplies convert 115 V AC to the voltage required by the heated window and humidistat.

MINI-ARRAY Heated Enclosure 

   - a) Route the heater supply cable to the top of the enclosure along one side wall. 

   - b) Cut off any excess cable, leaving enough to make the connections. 

   - c) Secure the cable midway along the sidewall, using one of the supplied cable clips. 

   - d) Strip the heater supply cable insulation as shown. 

   - e) Install the ring terminal on the ground wire. 

   - f) Install the male connector pins on the two power wires, using Molex crimping tool model HTR01031E, or equivalent. g) Push the power wires into the two male connector pins, and crimp. 

   - h) Insert the pins into the Molex 2-pin connector. Attach the ring terminal to the hole at the upper back of the enclosure, using the supplied #10 hardware. 

2. Connect the humidistat supply cable. 

   - a) Insert six spring nuts into the rear slots in the back of the enclosure, three on each side. (Two nuts will be for attaching the humidistat bracket, and four will be for attaching the sensor brackets, at top and bottom.) 

   - b) Mount the humidistat/bracket assembly to the upper back of the enclosure. 

   - c) Push the two wires with blade terminals into place on the humidistat wiring harness; push firmly until they “click” into place. (Connect either wire to either terminal; polarity is not important.) 

3. Connect the sensor cable.

- a) Route the sensor cable terminal to the top of the enclosure, leaving enough to bend it at the top and plug it into the sensor. If you are supplying non-Banner cables and using the field-wireable connector, go to the next sub-step. 

- b) To install the field-wireable connector, follow the wiring connections as shown. Allow enough space at the top of the Heated Enclosure when mounting the sensors to accommodate this connector’s additional length (as compared with the standard Banner QD cable). 

The connector pins accept up to 14 gauge stranded wire; 16 gauge stranded wire is recommended for the sensor cable wires. 

## Mount and Align the Sensor 

Follow these instructions to mount and align the sensor. 

## **Note:** 

   - **Heat and Burn Warning** 

   - The glass and window frame are hot; a burn may result. 

   - Do not touch the glass or window frame when the heating element is on. 

1. Assemble the brackets supplied with the Heated Enclosure to each end of the sensor, using 2 hex head screws with integral compression washer per bracket (M4 x 10 – non QD end; M30 Nut and washer – QD end, supplied with sensors). (Although both screws and brackets are supplied with each MINI-ARRAY sensor, use only the brackets packed with the Heated Enclosure.) 

2. Adjust the location of the spring nuts in the rear slots to align with the holes in the sensor mounting brackets and install the sensor using the supplied #10 hardware. 

3. Adjust the height of the sensor to match the height of the opposing sensor; ensure that the sensor lens is oriented parallel to the enclosure window. 

4. Connect the sensor cable to the sensor’s QD connector. See the instructions packed with each sensor for connecting the sensor cable to the array controller. 

5. After all sensor wiring is completed, follow the instructions packed with the sensor controller for optimizing alignment. Rotate the enclosure as needed to align the emitter and receiver arrays. 

## Final Assembly Instructions 

1. Attach the second cable clip to the inside of the cover plate. See Figure 1 on page 2.

2. Assemble the cover plate to the housing using the supplied #8 hardware. 

3. Attach the heater supply cable to the cable clip on the cover plate. 

4. Connect the heater supply cable to the heated window assembly. 

5. Mount the heated window assembly to the enclosure using the supplied #8 hardware. 

6. Connect the heater power cable to the cable from the Transformer Power Supply (see instructions packed with Power Supply). 

The red LED at the top of the heated window assembly indicates when the heater element is active. 

## Operating the Heated Enclosure 

The humidistat is adjustable between 20% and 80% relative humidity. The factory setting is 80% relative humidity, which is the optimal setting for most applications. 

- To eliminate the humidistat from the window control circuit, turn the knob fully counter-clockwise to the OFF position. 

- To manually close the contacts on the humidistat, turn the knob fully clockwise to the ON position. 

For accurate operation, do not attempt to adjust the humidistat below 20% or above 80% relative humidity.
