EZ-SCREEN LP Instruction Manual a. Two pairs in a horizontal plane Installation and Overview Alignment 3.2 Mechanical Mounting Procedure Emitter Receiver Once the mechanical layout considerations of Section 3.1 are addressed, mount the sensors and route the cables. Receiver Emitter 3.2.1 Sensor Mounting Emitter/receiver pairs may be spaced from 0.1 m to 7 m (4" to 23') apart. This distance is reduced if corner mirrors are used (see Section 3.1.7). Scan Code 1 Scan Code 1 Receiver 1 Emitter 1 Scan Code 1 b. T wo or three pairs stacked (or alternate receiver/ emitter positions) Receiver 2 Each sensor is shipped with two end-cap brackets and at least two side-mount brackets. The supplied end-cap brackets allow 360° rotation. Side-mount brackets allow 30° rotation in one direction, and 10° in the other (see Figure 3-10). Sidemount brackets may be mounted on either or both sides of the housing. If additional rotation is required, see the accessory brackets in Section 2.4. Center-mounted side brackets must be used with longer sensors, if they are subject to shock or vibration. In such situations, the sensors are designed to be mounted with up to 690 mm unsupported distance (between brackets). Sensors 830 mm and longer are supplied with one or more additional side brackets for center-mounting (see Figure 3-10). Emitter 2 Scan Code 2 Mounting the End-Cap Brackets Emitter 3 Receiver 3 Scan Code 2 c. T wo pairs at right angles Scan Code 1 Receiver Emitter Scan Code 2 1. From a common point of reference (ensuring the minimum separation distance calculated in Section 3.1.1), measure to locate the emitter and receiver in the same plane, with their midpoints directly opposite each other. Important: The connector ends of both sensors must point in the same direction (see Figure 3-5 and warning, Section 3.1.4). Loosely mount the brackets to the desired surface, using the supplied M5 bolts and nuts, or user-supplied hardware. Brackets may face “in” or “out,” as desired (see Figure 2-6). 2. Attach the end-cap bracket plate to each end of the sensor, using the supplied M3x6 screws. d. Multiple pairs in a horizontal plane Horizontal Emitter Horizontal Receiver Opaque Shield Example shows 2 methods: either alternate scan codes or insert an opaque shield when multiple pairs face the same direction Receiver 1 Receiver 2 Emitter 2 Emitter 3 Receiver 3 Emitter 1 Scan Code 1 Scan Code 2 Scan Code 2 3. Position the emitter and receiver in their brackets, as shown in Figure 3-11. Loosely attach the front bracket plate to the bracket, at each end. 4. Verify that the sensor windows directly face each other. Measure from a reference plane (e.g., a level building floor) to the same point(s) on the emitter and receiver to verify their mechanical alignment. Use a carpenter’s level, a plumb bob, or the optional LAT-1 Laser Alignment Tool (see Section 2.5) or check the diagonal distances between the sensors, to achieve mechanical alignment; see Figure 3-11. Final alignment procedures are explained in Section 3.4. 5. Tighten all fasteners. Figure 3-9. Installation of multiple pairs; alternate emitters and receivers to avoid optical crosstalk.
