Description
Point of Operation Control (POC) safety light curtains are active opto-electronic protection devices (AOPD) with resolutions of 14mm (0.55in) or 30mm (1.18in). Allen-Bradley Guardmaster POC safety light curtains are selfchecking and belong to Safety Category 4. They have been designed for industrial applications and are characterized by: * * * * * * High degree of reliability Maintenance-free components Practical size Sturdy modular construction Universal application possibilities Simple installation
Protected Height Scanning Range Resolution Enclosure Rating Connection Type Supply Voltage Uv Maximum Residual Ripple Power Consumption Synchronization Outputs Minimum output voltage Response Time Protection Connection Maximum wire cross section Cable length
Features
* Maintenance-free operation * Control-reliable solid-state outputs * State of the art microprocessor technology with custom-designed ASICs (Application Specific Integrated Circuits) * Easy assembly and alignment * Quick-disconnect mini style connectors * Long scanning range and high resolution * Small housing cross section: 52mm x 55mm (2.05in x 2.17in) * Fast response time 15ms * Large excess gain * Possibility to daisy-chain two sensors (to prevent personnel from standing between protective field and the point of operation) * Construction in compliance with EN 50100 Category 4 (self-checking) * Tested and approved for USA, Europe, Canada and Japan

Electrical Installation Connecting the POC components is simple. Cable lengths up to 60m (196.8ft) are permitted (over-voltage protection for level 3 and higher (IEC 801), see Technical Data). The transmitter is connected to a 24V supply using a 7-conductor cable. The receiver is connected to the machine control and 24V supply using a 7-conductor cable. The maximum wire cross section is 1.5mm (0.06in) without jacket; 1mm (0.04in) with jacket. All light curtains come standard with prewired mini style quick-disconnect connectors in the end-caps. The POC requires +24V DC ( 20%) power supply, which is available from Allen-Bradley Guardmaster. LED Indicators
Transmitter Receiver
POC (transmitter) cable pin diagram Test Input (Transmitter) The POC switches to the green condition after the supply voltage has been applied, and the automatic power-up test has been completed. If an external test is desired, a contact (normally closed) can be connected at the test input (MCC = Machine Control Contact). Minimum opening duration 50ms. Continuous current during closed test input: 12mA. In-rush current when closing: 150mA (20ms). Test input open = Testing = Outputs on receiver inactive (red). Test input closed = No test Outputs on receiver active (green).

Outputs (Receiver) The output voltage UA of each channel depends on the supply voltage UV and the switched load and is at least UA = UV - 2V Both outputs OSSD1 and OSSD2 (OSSD = Output Signal Switching Device) are control reliable, actively monitored PNP solid state outputs. The outputs can carry a maximum of 0.5 Amps and are short circuit protected. If the protected field is clear, the two outputs are HIGH (active). * An additional supply voltage must not be applied to the outputs.
