Banner MAXI-BEAM sensors are highly versatile, self-contained, modularized photoelectric sensing controls that are ideally suited to industrial environments. The basic MAXI-BEAM is an ON/OFF switch consisting of three modules: a sensor head, a power block, and a wiring base.

Programming the MAXI-BEAM Sensor Head MAXI-BEAM sensor heads may be programmed for sensor response time (and range) and for LIGHT/DARK operate. Each sensor head is supplied with a programming ring which attaches MAXI-BEAM HS: HI SPEED 2W: 2 WIRE below the the sensor head by a system of pegs. There are four programming notches around the HP: HI POWER SP: SPECIAL perimeter of the ring. To program the sensor head, simply find the notch which will line up with DARK LIGHT the desired program combination (see diagram, right). NOTE: the programming ring may have OPERATE OPERATE to be turned upside-down in order to line up the notch with the program. If LIGHT OPERATE H S 2 H H S 2 H is selected, the MAXI-BEAM output will energize on a dark-to-light transition. If DARK S P W P S P W P OPERATE is selected, the MAXI BEAM output will energize on a light-to-dark transition. In the illustration, the MAXI-BEAM is set for high speed (HS) operation in the LIGHT OPERATE output state. See the information about each individual sensor head for the response time and range associated with each setting (HP, 2W, HS, SP). NOTE: when programming the RSBE, RSBSER, or RSBEF emitter, select the mode which is programmed for the receiver. EXCEP- TION: if the receiver is programmed for the 2-wire (2W) mode, select high power (HP) on the Programming ring Notch emitter.

7 MAXI-BEAM Power Blocks and Wiring Base

MAXI-BEAM power blocks provide regulated low voltage dc power to the sensor head and logic module (if one is used), and all power blocks (except emitter-only types) contain an output switch for interfacing to loads or to control circuitry. Power blocks plug into the model RWB4 wiring base which has heavy-duty screw terminals that accept up to #12 gauge wire (no lugs are necessary). The RWB4 wiring base is necessary for all MAXI-BEAM sensor assemblies (except sensors using the RPBTLM power block), and must be purchased separately. All power blocks, except the emitter-only types, include status LEDs which continuously indicate the state of the output circuit and input power. MAXI-BEAM power blocks are epoxy-encapsulated and rated for -40 to +70 degrees C (except models RPBR and RPBR2). RWB4 Wiring Base Power Block (order separately) All MAXI-BEAMs have circuitry to prevent false closure of the output on power-up.

When 2-wire 1 MAXI-BEAMs are wired together in parallel, any power block which has an energized output will rob all other 2- wire power blocks of the voltage needed to operate the sensor.

12 MAXI-BEAM Power Blocks Model RPBTLM Low Profile DC Power Block Model RPBTLM is a miniature dc power block for MAXI-BEAM sensors. It may be used with any of the MAXI-BEAM sensor head models. The RPBTLM is supplied with stainless steel hardware used for assembly of the MAXI-BEAM components. Components simply bolt together, with no interwiring necessary. The screws supplied are extra-long, and serve as a means to mount the complete MAXI-BEAM sensor assembly to an object or surface. The RPBTLM may be attached to its sensor head at any of four 90-degree increments to allow the best cable exit direction (front, rear, or either side). A logic module may be added and can be independently rotated (in the same manner) for easiest access to the timing adjustments. Outputs are in the bi-polar configuration: one current-sinking (NPN) plus one current-sourcing (PNP). This design permits direct interfacing of the MAXI- RPBTLM Dimensions BEAM sensor to almost any type of dc logic input. Each output is rated for 150 mA. Either output may be used alone, or both may be used simultaneously. The outputs may be configured for either normally open or normally closed operation via the sensor head (or logic module) programming ring. The RPBTLM includes an LED indicator to show the output status. The RPBTLM is completely solid-state and epoxy-encapsulated. It is gasketed to other MAXI-BEAM components by a quad-ring seal. See pages 3,7, and 14- 15 for information on the assembly and programming of MAXI-BEAM sensors.

13 MAXI-BEAM Logic Modules MAXI-BEAM sensors offer built-in timing logic with the addition of a logic module. There are two logic modules available. Model RLM5 is programmable for ON-DELAY, OFF- DELAY, and ON/OFF DELAY timing logic. Model RLM8 offers both ONE-SHOT and DELAYED ONE-SHOT functions. A programming ring is supplied with each logic module. Programming of the logic function, timing range, and output state is similar to sensor head programming.

Both logic modules feature 15-turn, clutched potentiometers for accurate timing adjustments. Once programmed, the logic module may be rotated in 90-degree increments to position the timing adjustments for easiest access. Logic modules are housed in the same tough molded VALOX® which is used for the other MAXI-BEAM components. The logic module and its programming ring simply slip between the MAXI-BEAM sensor head and power block (see photograph, page 3). The assembly is bolted together with no interwiring necessary. The component interfaces are quad-ring sealed.

They will be held together temporarily by their interlocking pegs. 3) Orient the logic module for easiest access to the timing adjustments, and assemble between the programming ring of the sensor head and the power block (see exploded view on page 3). Bolt all parts together with the long bolts that are supplied with the logic module. 4) Apply power to the MAXI-BEAM and adjust timing, using a small flat-blade screwdriver.
