1 / 8 page 2-26 Presence Sensing Safety Devices Safety Light Curtains Point of Operation Control 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 self- checking 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 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 Specifications ➊ The POC without using a separate control unit, will operate in a guard only mode with automatic restart. Maximum scanning range 6m/18m (19.69ft/59.06ft) Resolution (object sensitivity) 14mm/30mm (0.55in/1.18in) Maximum height of protective field 1814mm/1832mm (71.4in/72.1in) Minimum height of protective field 314mm/332 mm (12.36in/13.07in) The optical axis (centre of window) is marked on the end cap. Standards EN 50100 Approvals BG, cULus and CE marked for all applicable directives Protected Height 314mm...1832mm (12.3in...72.1in) Scanning Range 0.3m...6m (0.98ft...19.6ft)/0.3m...18m (0.98ft...59.0ft) Resolution 14mm/30mm (0.55in/1.18in) Enclosure Rating IP 65 Connection Type 7-pin mini style quick-disconnect on transmitter and receiver Supply Voltage Uv Maximum Residual Ripple 24V DC ± 20% 5 Vss Power Consumption 0.9...1.5 Amps (no-load) Synchronization Optical, without separate synchronization channel Outputs Minimum output voltage 2 x PNP, 0.5 A, short circuit protected Uv - 2V Response Time ≤15ms Protection Short circuit and overload Connection Maximum wire cross section 1.0mm2 with jacket 1.5mm2 without jacket Cable length 60m (196.8ft) Protection against over-voltage ( ≥1kV) from Level 3 or higher (IEC 801 part 5; 2 kV) between PE and +V. Mode of Operation➊ Guard-only with automatic restart Safety Category Type 4 (self-checking) Requirement According to EN 50100 Operating Ambient Temp. 0°C to 55°C (32°F to 131°F) Air Humidity 15%...95% (not condensing) Storage Temperature -25°C to 70°C (-13°F to 158°F) Approximate Dimensions Height Housing cross section Length dependent upon protected height; (see dimensional drawings) 52 mm x 55 mm (2.05in x 2.17in) |
