The purpose of this standard is to The following example relates to a unit which has a snap action harmonize as much as possible the product performance and test basic and which has a roller pin plunger actuator i.e. GLCB01C. requirements for equipment where the rated voltage does not ex- ceed 1,000 VAC or 1,500 VDC. When reading these bar charts follow these rules: 1. Check what type of actuator was used to test the product, this IEC 947-5-1 is part 5 of the general rules which relates to Control- is on the drawings which show the head style available. It will circuit devices and switching elements. Also within this part there be one of two types: is a section which considers Special Requirements For Control a) Vertical travel plunger Switches With Positive Opening Operation. Any control switch b) Linear cam travel which has this positive opening operation and conforms to these 2. Start reading from top left of figure B, at the arrow labeled special requirements will be marked on the outside of the product ‘‘A’’. with this symbol: 3. Follow the black arrows and the black strip on the chart. The black strip indicates that there is a circuit between the termi- nals whose numbers are shown on the left and when white there is no circuit. The Contact Element Form defines the configuration of the contacts and the number of contacts within the switch. e.g. All dimensions are in mm/(inches). Form Za – both contact elements have the same polarity. Form Zb – the two contact elements are electrically separated. The Utilization Category defines the type of current carried (AC) Alternating current, (DC) Direct current and the typical application in which the switch is used e.g. AC15 – Control of Electromagnetic Loads (less than 72VA) DC13 – Control of electromagnets. The contact rating Designation relates to the utilization categories and defines the conventional thermal current lth (A), rated oper- ational current le (A) at rated operational voltages Ue and the VA rating e.g. A600 – The ‘‘A’’ denotes the maximum VA rating (AC) and the Figure A ‘‘600’’ denotes the maximum rated (AC) voltage. Q300 – The ‘‘Q’’ denotes the maximum VA rating (DC) and the ‘‘300’’ denotes the maximum rated (DC) voltage. These IEC standards have been adopted by CENELEC (The Eu- ropean Commitee for Electrotechnical Standardization) and have been identified by replacing IEC with EN 60 e.g. IEC 947-5-1 then becomes EN 60947-5-1. CENELEC has defined the dimensions and characteristics of two types of limit switch in the standards EN 50041 and EN 50047. These standards relate to Low voltage switchgear and control- gear for industrial use and define the enclosure dimensions, the operating point for various head actuators, the earth terminal re- Figure B quirement, the terminal marking and the minimum degree of IP protection. Look at Figures A and B as examples. Actuator type used for test is the linear Cam travel type (b) shown left. The start point is at the ELECTRICAL RATINGS arrow marked ‘‘A’’ (See fig. B). This shows the free position to be 5.3 IEC947-5-1 / EN60947-5-1 mm from the vertical center line of the unit.

The following tools will be needed – depending on the task. Posidrive screwdriver n° 1& n° 2 Never use the Limit Switch as a physical end stop. Mechanical Allen key 3 mm damage or incorrect operation may occur if this is done. Always ensure that the mechanical actuator is protected from excessive When tightening a screw down the maximum force which should be mechanical shock. Never release the actuator suddenly – gradual applied should not exceed 80N.cm (7in.LB) on any screw on the actuation and release will ensure that stress on the mechanics of the complete assembly or basic switch terminal. switch is kept to a minimum. This has the added benefit that the switch life will be improved. Mounting Instructions Mounting, Installation and Wiring of the Limit Switch plays a critical The following diagrams illustrate how to actuate your limit switch for role in the performance of the switch in service. Care should be optimum performance. taken in the position and orientation of the switch for optimum performance. All of the guidelines given below apply equally when replacing parts on the switch. Wiring The GLS series has been designed to accept 14AWG wire maxi- mum. Care should be taken to ensure that the wires are carefully arranged in the switch so that they do not overlap or otherwise interfere with the operation of the switch when the switch cover is replaced. If the wires are trapped between the basic and the cover then the switch may fail to operate correctly – ensure that an adequate gap exists between the fitted wires and the cover when fitted. It is not good practice to have very different diameter wires share the same terminal in the switch – uneven pressure on the wires will result. For limit switches with pushrod actuators, the actuating force should be applied as nearly as possible in line with the pushrod axis. Mounting The GLS series has been designed to be extremely flexible in mounting. Elongated mounting holes mean that the switch can be adjusted substantially prior to fixing in position. We recommend M4 maximum screws be used for mounting the switch in its application. Fix and test the switch for intended switch point in the application. When mounting the switch ensure that it is positioned to allow natural drainage of any moisture which may enter the enclosure during service. Natural drainage can be achieved by mounting the switch upright with the conduit entry at the bottom of the switch. Mounting the switch in the upright position will enable maintenance and replacement procedures to be carried out easily. Adjustment and Set-up Cam or dog arrangements should be such that the actuator is not suddenly In general no adjustment of the GLS should be necessary beyond released to snap back freely. correct mounting of the switch body as required. It is possible to change the switch actuator orientation. The example below shows a top roller plunger head rotated through 90°. The other head styles can also be rotated. Operating mechanisms for limit switches should be so designed that, under any operating or emergency conditions, the limit switch is not operated beyond its overtravel limit position. A limit switch should not be used as a mechanical stop. The head can be rotated by carefully removing the four combination head screws holding the head in position. Carefully remove the head assembly and rotate to the desired position. Replace the head assembly and tighten the mounting screws. Ensure that the head is properly located. Hand test the actuator to ensure that the switch functions and the actuator moves freely (sticking can occur if materi- For limit switches with lever actuators, the actuating force should be applied as nearly perpendicular to the lever as practical and perpendicular to the shaft axis al has been deposited inside the drive train whilst the head assem- about which the lever rotates. bly was removed).

There are two lever mounting options: (1) By fully seating the lever in one of the four 90° detent positions on the shaft hub which provides positive lever retention; (2) By mounting the lever on the serrated portion of the shaft (which enables the lever to be mounted in any Replacement Instructions position).

The basic switch is secured in the miniature housings by a press fit. To remove an inoperative switch, merely grasp the basic firmly and pull it out of the housing. Insert the new switch in its place. Then wire the new basic as before and test it in the application. Plug-in EN 50041 body style The switch enclosure portion of this two-piece body style plugs into a pre-wired terminal block mounted in the application.
