Edwards GE-Security 128C GuardSwitch Installation

Series 100 128C Interlock Position Installation Sheet To avoid switch failure determine the actual load of the circuit and take steps to protect the switch from voltage spikes inrush and line load capacitance using the following 1 Dimensions Surges from coils motors contactors solenoids and tungsten Transient protection such as back to back zener diodes or an RC network is recommended for such loads to that maximum ratings of the switch are not exceeded capacitance and load capacitance An in line resistor can be in series immediately before the load to limit the inrush The resistor can only be added in series with the last wire before the load The voltage drop and the power rating of the must also be calculated as follows drop l R l R maximum continuous current of the load verify switch operation with an ohmmeter a normally open switch the meter will read high resistance with the away 0L or greater than 10 Mega Ohms The meter will read low resistance with the actuator in sense range less than 1 Ohm will see the opposite reading for a normally closed switch install the device Determine a suitable mounting location using the following The switch and actuator must be within the Listed sense See Table 2 The sense ranges are based on the switch and actuator being so that the sensing surfaces are face to face See 2 When mounting in proximity to ferrous material the sense range can be reduced 50 percent minimum on the shape and type of the material Test the in specific applications to determine the actual sense When mounting on a ferrous material steel a 1 4 in non plastic or aluminum spacer may be used around the and switch to restore most of the lost gap When mounting on a hinged gate or door mount the switch actuator 6 inches away from the hinges to achieve movement The switch and actuator must move in one of the approved See Figure 3 The actuator can be mounted at a 90 degree rotation to the Do not mount for parallel actuation An on off on signal may when the actuator passes by the switch Mount the switch on the stationary frame of the machine and the electrical wiring When mounting the switch on an machine connect the ground lead to one of the screws Mount the actuator on the moveable guard door or gate Risk of equipment damage Do not force or hammer may damage the switch Slightly over drill the holes for easy insertion The switch and should easily slide or screw into the predrilled holes in cm in cm x 1.25 in cm in cm in cm 2 Position 3 Barrel Switch mounting configurations Perpendicular Three configurations are appropriate for recessed interlock end to end side by side perpendicular Moving the parallel to the switch can result in on off on signal if the passes by the switch rather than coming to rest in proximity to This is not a recommended configuration for interlock position The configuration results in non actuation 1 3890 0404 13252 REV E ISS 26APR16 2 1 General specifications range rating class time cycles resistance types O D steel threaded barrel with 2 nuts dia 1.25 thread 50 mm long to 180 40 to 80 sealed contact switch in polyurethane 2 3 4X 5 6 12 67 msec under full load up to under dry circuit Ohms jacketed 0.164 in 0.41 cm jacketed J 0.16 in 0.41 cm models Each electrical rating is an individual maximum and cannot be exceeded 2 Ordering Electrical specifications and wire color codes number N O rating N C N C For all 128C models the Black wire is the Common contact Configure with actuator away from the switch current AC DC voltage AC DC 120V 0.11A 0.5A 30V 0.5A 30V 0.2 Ohms 120V 0.11A 0.5A 30V 0.5A 30V 0.2 Ohms 120V 0.11A 0.5A 30V 0.5A 30V 0.2 Ohms 1.0A 25V 0.2 Ohms 120V 0.2A 120V 0.2A 1.0A 25V 0.2 Ohms 1.0A 50V 0.2 Ohms 120V 0.4A 120V 0.4A 1.0A 50V 0.2 Ohms length ft 1.8 m ft 1.8 m ft 3.6 m ft 1.8 m ft 3.6 m 22 2 ft 1.8 m ft 3.6 m 3 Sense range 1 or 128G 6 description magnet in M8 1.25 50 stainless steel threaded barrel two jam nuts magnet in M12 1 70 stainless steel threaded barrel two jam nuts Alnico magnet 3 8 in dia 1 1 2 in long earth 0.6 in dia 0.12 in thick with 4 countersink hole Proximity of ferrous materials usually reduces the sense range typically by 50 percent The shape and type of material cause a wide diversity effects Testing is required to determine the actual sense range for specific applications information contact information see www edwardsfiresafety com 2016 Walter Kidde Portable Equipment Inc rights reserved 2 1 3890 0404 13252 REV E ISS 26APR16
