EXPANSION BOARD WIRING ACCESSORIES TO THE EXPANSION BOARD Refer to the chart below and the corresponding image for a description of the expansion board inputs. A Entrapment Protection Device Inputs EYES ONLY Input: Open or Close Direction Photoelectric Sensors, Close: reverses fully, Open: stops (4 terminals total), Open or Close gate/door Direction based on switch setting next EYES/EDGE Input(s): Open or Close Direction Photoelectric Sensors, Infra-red detector wired or Edge to inputs Sensor, Close: reverses fully, Open: stops gate/door B Single Button Control, SBC (2 terminals) Gate/door command sequence - Open, Stop, Close, Stop, ... Soft Open ,Soft Close, Soft Stop (maintained switch does not override external safeties and does not reset alarm condition) C Open Input (& common) (3-Button Control Station, 4 terminals total) Open command - opens a closed gate/door. Soft open (maintained switch does not override external safeties and does not reset alarm condition) If maintained, pauses Timer-to-Close at OPEN limit. Opens a closing gate/door and holds open an open gate/door. D Close Input (& common) (3-Button Control Station, 4 terminals total) E Stop Input (& common) (3-PB station, 4 terminals total) F Exit Loop Input (2 terminals) G Shadow Loop Input (2 terminals) H Interrupt Loop Input (2 terminals) Close command - closes an open gate/door. Soft close (maintained switch does not override external safeties and does not reset alarm condition) Stop command - stops a moving gate/door. Hard stop (maintained switch overrides Open and Close commands and resets alarm condition) If maintained, pauses Timer-to-Close at OPEN limit. Overrides an Open or Close command. Loop wire connection for plug-in loop detector when loop is inside secured area near gate/door. Open command - opens a closed gate/door. Soft open (maintained switch does not override external safeties and does not reset alarm condition) If maintained, pauses Timer-to-Close at OPEN limit. Opens a closing gate/door and holds open an open gate/door. Loop wire connection for plug-in loop detector when loop is positioned under the gate/door. - Holds open gate/door at open limit - Disregarded during gate/door motion - Pauses Timer-to-Close at Open Limit Loop wire connection for plug-in loop detector when loop is along the side of the gate/door. - Holds open gate/door at open limit - Stops and reverses a closing gate/door - Pauses Timer-to-Close at Open Limit - Activates quick close and anti-tail features if enabled POWER 1 EYE ONLY 2 EYE/ EDGE 3 EYE/ EDGE COM SBC OPN CLS STP COM TO MAIN BOARD A Photoelectric Sensor Photoelectric Sensor or Edge Photoelectric Sensor or Edge B C N.C.
