Installation Instructions for the Enclosed Basic Series Limit Switches WARNING Issue 5 88173 MOUNTING PERSONAL INJURY 1. Mount switches on flat, rigid surface. DO NOT USE these products as safety or emergency stop devices or in any other application where failure of the product could result in personal injury. E6 Side Mounting Pattern 25,4 mm [1.00 in] Failure to comply with these instructions could result in death or serious injury. E6 SIDE MOUNTING 2X CLEARANCE HOLE FOR #6 MOUNTING SCREW* V6 Flange Mounting Pattern GENERAL INFORMATION • Honeywell’s Enclosed Basic Series of Limit Switches are usable in many applications. The wide variety of actuators offered and their robust diecast housing make them ideal for applications that require reliable switching and performance. There are several styles of enclosed basic switches, including side and flange mounting switches as well high capacity and double pole type. • Refer to switch labeling for applicable electrical ratings and certifications • For technical product support, engineering drawings, technical data, and additional information for products from Honeywell’s Enclosed Basic Series of Limit Switches please visit sensing.honeywell.com, or call the support numbers on the last page of this document. 41,6 mm 1.63 in V6 FLANGE MOUNTING 2X Ø 4,3 mm [0.17 in] MOUNTING HOLES G1 Side Mounting Pattern 75,0 mm [2.95 in] 31,0 mm [1.22 in] G1 SIDE MOUNTING 2X Ø 5,5 mm [0.216 in] MOUNTING HOLES H1 Flange Mounting Pattern 41,9 mm 1.65 in H1 FLANGE MOUNTING 2X Ø 0.22 5,5 mm [0.22 in] MOUNTING HOLES 2. Boot-sealed and side-mounting switches use sealing washers under screw heads on the sides between switch and mounting surface on other side to maintain seal. 3. Unsealed, side mounting switches: Use lockwashers under screw heads on one side; under nut on other side. 4. Connect conduit to conduit opening. Apply conduit sealing if required by application. INSTALLATION TIPS 1. Do not lubricate any internal part of the switch. The internal switch does not require any additional lubrication 2. When installing the switch, ensure that it is not the low point in the conduit run. Doing so will ensure that condensation created in the conduit will not flow into the switch housing. 3. Do not enlarge the mounting holes on side mounting switch. Doing so will compromise the internal switching element’s seal integrity. Sensing and Control Enclosed Basic Series Limit Switches FIELD ADJUSTABLE ACTUATOR MODELS Some enclosed basic switches are field adjustable. This includes models with the nomenclature “2RN2”, ”2RQ2”, ”2RN28”, ”2RQ28”, “2RN62”, “2RQ62”, “RQ2X2”, “RN2X1”. ADJUSTABLE RANGE LEVER RETAINING NUT LEVER BASE RETAINING NUT ISSUE 5 88173 N18 TYPES If actuator or basic switch is replaced, the actuator may need adjustment to duplicate original switch operating point. To adjust operating point, remove lower seal band from base of seal boot. “Peel back” seal boot to expose bushing. With basic switch unoperated, slowly turn bushing clockwise until basic switch operates. Do not turn further after operating click is heard. Turn bushing back 1/2 turn. Tighten jam nut on bushing. MAINTAINED CONTACT (RESET) MODELS Listings with an “X” in their part number are maintained contact switches. These switches remain actuated after the operating force on either plunger has been applied. The actuated plunger will “reset” when the opposing plunger is actuated. NOTE: The top plungers (the plungers on the stationary portion of the housing) provide more accurate and uniform operation than the “reset” plungers and should be used when closely held operating characteristics are required. ADJUSTABLE RANGE 360~ABOUT THE PLUNGER AXIS The lever can be adjusted in two ways. The following process details how to perform the adjustments. Adjusting the horizontal position of the lever. 1. Loosen the lever base retaining nut, so that the lever assembly is free to rotate about the axis of the plunger. 2. Rotate the lever to the desired position. The lever is adjustable 360 degrees about the axis. 3. Once the desired position is reached re-tighten the lever base retaining nut. The lever base should not be able to rotate when properly tightend. Adjusting the vertical position of the lever. 1. Loosen the lever retaining nut, so that the lever freely rotates. 2. Set the position of the lever to the desired position. Roller levers should be positioned so that they are able to actuate the plunger. 3. Once the desired position is reached re-tighten the lever retaining nut. When pushed the lever should act upon the lever mechanism to actuate the switch. 2 Honeywell Sensing and Control Vertical Adjustment Range N2 & Q2 - Roller lever 225° N4 & Q4 - Hand op. 180° N62 & Q62 - Rod lever 225° N28 & Q28 - One way 180° To adjust: loosen hex nut, adjust arm to desired position, tighten hexnut. 1. One lever arm serration: 8.18°. 2. One serration of lever arm and fluted washer as a unit: 8°. 3. One serration of lever arm with one serration of fluted washer in opposite direction: 0.18°. LUBRICATING INSTRUCTIONS for Roller Plunger Switches only (N80, N81, Q8, Q9, Q81) For maximum life, periodically put a drop or two of lightweight oil on the roller. Specific application conditions will determine lubricating frequency. Enclosed Basic Series Limit Switches WIRING • Honeywell’s Enclosed Basic Switches have internal terminals that allow for easy wiring and integration. • If a side mounting switch is being wired it is possible for the switch to be mounted in place before wiring takes place. If a flange mounting switch is being used it is likely that that the switching and actuator assembly will need to be wired before mounting switch. The enclosed basic series switch will have one of two contact forms available. They will either have a single pole double throw (SPDT) or a double pole double throw (DPDT) arrangement. The SPDT uses three terminals to wire a set of Common (C), Normally Open (NO), and Normally Close (NC) contacts. • ISSUE 5 88173 • Once the cover of the flange base is removed the switch terminals will be exposed. Switch terminals will be labeled according to the contact they connect to. Please refer the terminal layout section for more information on circuit diagrams and terminal screw layout. • Connect wire to terminals by loosening terminal screws, looping wire around the terminal screw shaft, and inside of the cup washer on SPDT models or looping wire around the terminal screw shaft and underneath locking washer on DPDT models. Then retighten terminal screws ensuring wires and connections are made. • Grounding Terminal, enclosed basic switches have an internal grounding screw mounted inside the removable cover or flange base. • Replace cover or flange base and retighten cover screws Remove the cover or the flange base by loosening the two screws that secure it.
