6 zc- @ 55 operation indicator-equipped models (not approved by ul, csa, or en) ? all the models can be equipped upon request with a operat ion indicator to facilitate maintenance and inspection. ? because the indicator is incorporated in t he terminal protective cover, the dimensions of the limit switch are not affected. in this model, the lead wire is to be connected to the sc rew terminal. (a connecting washer is provided on the tip of the lead wire). the lead wire can be connected to either the nc or no terminal. ? operating characteristic s are the same as the standard model from which the operation indicator equipped model is fabricated. (for ac) ? the operating voltage range is from 90 to 250 vac. ? the dimensions are the same as the standard type. the top of the terminal protective cover is tr ansparent to allow checking the operation easily. ? when placing your order for the indicator equipped, ac-operated model, add suffix "l" to the end of the model number. example: standard type: zc-q2255 indicator equipped type: zc-q2255-l contact circuit note: if the wiring is as shown above, the operation of the respective parts will be as shown in the following table. the neon lamp is not wired when the switch is delivered. connect it as required. (for dc) ? the dc-operated is provi ded with an led indicator. ? there is no protective structure. ? since a rectifier stack is incorporated into the unit to permit reversing the polarity, this type can also operate on ac power source. ? the led projects from the housing for eas y visibility. ? when placing your order, add suffix "l2" or "l4" to the model number of the standard type. example: standard type: zc-q2255 indicator equipped type: zc-q2255-l2 contact circuit note: if the wiring is as shown above, th e operation of the respective parts will be as shown in the following table. the led terminals are not wired when the switch is delivered. connect it as required. nc terminal no terminal contact neon lamp load actuator nc on does not operate operates off operates does not operate no on does not operate does not operate off operates operates power supply neon lamp r = 240 k ? built-in switch load power supply neon lamp r = 240 k ? built-in switch load model voltage rating (v) leakage current (ma) internal resistance (k ? ) l2 12 approx.2.4 4.3 l4 24 approx.1.2 18 nc terminal no terminal contact led load actuator nc on does not operate operates off operates does not operate no on does not operate does not operate off operates operates power supply built-in switch resistor led load power supply built-in switch resistor led load
7 zc- @ 55 safety precautions refer to safety precautions for all limit switches . operating environment ? seal material may deteriorate if a switch is used outdoor or where subject to special cutting oils, so lvents, or chemicals. always appraise performance under act ual application conditions and set suitable maintenance and replacement periods. ? install switches where they will not be directly subject to cutting chips, dust, or dirt. the actuator and switch must also be protected from the accumulation of cutting chips or sludge. ? constantly subjecting a switch to vibration or shock can result in wear, which can lead to contact interference with contacts, operation failure, reduced du rability, and other problems. excessive vibration or shock can lead to false contact operation or damage. install switches in locations not subject to shock and vibration and in orientations that will not produce resonance. ? the switches have physical contac ts. using them in environments containing silicon gas will result in the formation of silicon oxide (sio 2 ) due to arc energy. if silicon oxide accumulates on the contacts, contact interference can oc cur. if silicon oil, silicon filling agents, silicon cables, or other silicon product s are present near the switch, suppress arcing with cont act protective circuits (surge killers) or remove the source of silicon gas. dog angle when operating the roller type, be sure to set the dog angle to less than 30 (even when operating at a low speed). operating the model at a dog angle exceeding 30 will soon cause abrasion or damage. do not apply a twisting force to the plunger. set the ot to 70% to 100% of the specified value so that the actuator will not exceed the ot. handling ? when detaching the terminal protective cover, insert a screwdriver and apply a force in the opening direction. do not use excess force to remove the cover. doing so may cause deformation in the fitting section and reduce the holding force. ? when mounting the terminal protective cover to the case, align the cover on the case and then press the cover down to mount it firmly. if the cover is pressed down in an inclined position, rubber packing will deform and thus a ffect the sealing capability. ? a 8.5-dia. to 10.5-dia. cable c an be applied as seal rubber for the lead wire outlet. (use two- or three-core cable of vct1.25 mm 2 .) ? use weather-proof rubber (chloropr ene rubber) as s eal rubber for the zc-n22(21)55. micro load models contact failure may occur is a g eneral-purpose switch is used to switch a microload circuit. use switches within the areas shown in the following chart. even wh en using microload switches within the area shown below, contact wear will becom e more extreme with loads that generate surge current when switching and durability will be adversely affected. if necessary, inse rt a contact protective circuit. microloads are indicated by n standar d reference values. this value represents the failure rate at a 60% ( 60) reliability level. (jis c5003) the equation 60 = 0.5 10 ? 6 /operations indicates that a failure rate of 1/2,000,000 operations can be expected at a reliability level of 60%. mounting ? when mounting the switch with screws on a side surface, fasten the switch with m4 screws and use washers, spring washers, etc., to ensure secure mounting. ? when mounting the panel mount- type enclosed switch (zc-q55, zc- q2255, or zc-q2155) with screws on a side surface, remove the hexagonal nuts from the actuator. appropriate tightening torque a loose screw may result in a malfunction. be sure to tighten each screw to the proper tighteni ng torque as shown below. operation with the zc-q22(21)55, an appropriate ot line is marked on the plunger. set the ot so that it is between the two x-surface lines. precautions for correct use not suitable suitable rubber packing rubber packing model zc- @5 5-01 zc- @ 55 minimum applicable load 5 vdc 1ma 5 vdc 160ma no. type appropriate tightening torque (1) terminal screw 0.78 to 1.18 nm (2) panel mounting screw 4.90 to 7.84 nm (3) side mounting screw 1.18 to 1.47 nm applicable area for general- purpose models (zc- @ 55) 30 24 12 5 0 1 10 100 1,00 0 current ( ma ) dc voltage (v) 0.1 100 ma 1 ma 26 ma 0.8 w 100 ma 160 ma not applicable applicable area for microload models (zc- @ 55-01) tw o , 4.3-dia. or m4 screw hole s 2 5 . 4 mounting holes 14.5 +0.2 0 dia. mounting holes
