Edwards 200 Series Installation Instructions 2013

Series 200 Safety Switches Instructions Con 1 Actuation surface testing face approach is achieved actuator on the moveable guard door or gate Instructions Do not wire the switch until it is mounted and tested Select a mounting location where the switch and actuator can be installed with their labels reading in the same direction Mount the switch on the stationary frame of the machine and For best protection against operator defeat mount with non removeable screws bolts or nuts See accessories The switch and actuator must be mounted so that the actuator moves in one of the approved directions Figure 1 Parallel actuation is NOT recommended and may cause switch An on o double actuation signal may result when actuator passes by the switch rather than coming to rest in proximity to it When mounting on a hinged gate or door mount the switch and actuator at least 6 away from the hinges so a more face The actuator can be mounted at a 90 rotation Keep the switch and actuator within the listed sense range see speci switch electrical speci Mounting on a ferrous steel material will reduce the sense aluminum spacer installed under the actuator and switch will When mounting a metal switch to an ungrounded machine connect the ground lead to one of the switch mounting screws Particular care must be taken to determine the ac load of the switch circuit Surges from coils motors contactors solenoids and Transient protection such as back to back zener diodes exceeded Line capacitance and load capacitance must be considered An in line resistor can be added to limit the inrush current The resistor can only be added in series with the last red wire The voltage drop and the power rating of the resistor must be considered Voltage drop I R or an RC network is recommended for such loads ensure that maximum ratings of the switch are not a minimum of 50 A 1 4 nonferrous plastic or must be considered most of the lost gap before the load
