MULTI-BEAM 2-wire ac Scanner Blocks for MULTI-BEAM' 2-wire modular photoelectric sensois thephotoelectricspecialist A Banner 2-wire ac MULTI-BEAM Sensor is a compact modular self-contained photoelectric switch consisting of threc components: a scanner block, a power block, and a logic module. The scanner block, described in this data shect, comprises the housing for the sensor and conlains a complète modulatcd photoelectric amplifier, the emitter and receiver optoclements and lenses, and space for the other modules. The power block module (data sheet P/N 03508) provides the interface between the scanner block and the extemal circuit. Il conlains a power Uppcr Cover (lens) (supplice! with Scanner Block) Logic Module Scanner Block Housing Power Block supply for the MULTI-BEAM plus a switching device (except in emitter- only power blocks) to interface the sensor to the circuit to be controlled. The logic module (data sheet P/N 03507) interconnects the power block and scanner block both electrically and mechanically. It provides the desired timing logic function (if any) plus the ability to program the output for either light- or daik-operate. The emitters of MULTI-BEAM opposed mode emilter/iecciver pairs do not require a logic module.

Spécifications SUPPLY VOLTAGE: connections are made via a 2-wirc power block (see product data sheet P/N 03508). RESPONSE TIME: IOmillisecondsONandOFF(3000operationsperminute). NOTE: built-in false puise proleclion circuit liolds output off for 100 niilliseconds after power is initially applied. NOTE: Response/rei>ealabilir\- specs are indépendant of signal strength. REPEATABILITY OF RESPONSE: see individual sensor specs. SENSITIVITY ADJUSTMENT: easily accessible, located on top of scanner block beneath o-ring gasketed screw cover. 15-turn clutched control (rotate clockwise with a small screwdriver to increase gain). ALIGNMENT INDICATOR: red LED on top of scanner block. Banner's exclusive, patented Alignment Indicating Device (AID™) circuit lights the LED whenever the sensor detects itsown modulatcd light source, and puises the LED at a rate proportional to the received light level. CONSTRUCTION: reinforced VALOX* housing with components totally encapsu-lated. Stainless steel hardware. Meets NEMA standards 1.3. 12. and 13. OPERATING TEMPERATURE RANGE: -40 to +70 degrees C (-40 to +158 degrees F). A WARN1NG Thèse photoelec­tric présence sensors do NOT include the self-chccking redundant circuitry necessary toallowlhcir use in personnel safety applications. A sensor failure or malfunction can resuit in eitlterun ener-gized or a de-energized sensor output condition. Never use thèse products as sensing devices for personnel protection. Their use as sal'ely devices may create an unsal'e condition which could lead to serious injury or death. Only M ACHINE-GUARD and PERIMETER-GUARD Sys­tems, and other Systems so designaled. are designed to meet OSHA and ANSI machine sal'ely standards for point-of-operalion guarding devices. No other Banner sensors or controls are designed to meet thèse standards, and they must NOT be used as sensing devices for personnel protection. Printed in USA P/N 03498A4A
