Z:\Manuali\LM MRL100_942_699A1\Traduzioni Maggio 2015\LM MRL_942_699A1 V2r7 UK .docxA) Multirope MRL100 - list of included partsIncluded parts:N° 2 screws type TE M8 class 8.8 DIN933 (orISO 4762-M8-A2), with calibrated length forrope diameters [C]N° 1 MultiRope mod. MRL rope sensor [A]N° 1 Deflection rod [B]NOTE:A) The engraved letter [C] screws, is matchedto the following elevator rope diameters:F: N° 3 ropes, diameter 6,5 mmF: N° 4 ropes, diameter 6,5 mmF: N° 6 ropes, diameter 6,5 mmMultiRope includes only two screws butadditional can be optionally purchased.OTHER ROPE CONFIGURATIONSAVAILABLEB) MRL inner sensor width [A] sets howmany ropes can be inserted.Standard MRL100 width for ropes is 72mm, additional widths are available andMRL100 can be modified for belt tensionmeasurement or for the characteristics ofYour application.When handling the MRL100 transducer, prior installationon the ropes, avoid any contact of the measurementelement with hard metal parts or tools.B) MRL sensor installation on elevator ropes1) Apply [C] screws to [A] sensor like shown inpicture.2) Position the MultiRope MRL100 sensor [A] closeto the ropes, parallel to the cabin roof and insertall ropes in the slot between the screws, withoutoverlapping them.3) When all ropes are between the [C]screws, apply the [B] deflection rod asshown in picture.Distribute the ropes on the availablespace inside the MRL100, avoiding anycontact between the ropes and thethreaded part of the screws [C].4) Screw all calibrated [C] screws in the threaded[B] deflection rod holes.5) Evenly position the ropes along the innerMRL100 sensor slot width.6) Ropes are to be centered within the sensor width,for a good quality measurement.7) Screw [C] screws till they are touching the innerside of the deflection rod for having a correctrope deflection. Ropes are slightly bent and are totouch only the rounded edges of [A] sensor and[B] deflection rod.8) Ropes are not to overlap and are to be parallelbetween each other.9) When [A] Multirope MRL100 sensor is fixedon the ropes, use the elevator for some runswith inside the cabin the maximum payload(also jump in the cabin or make emergencystops), then calibrate with (MANU procedure)applying a known weight, in the cabin.Correct fixing position.10) ELECTRICAL CONNECTION OF MRL100 SENSOR TO 699 ELECTRONICSMRL100 rope sensor has a cable with an RJ male connector, fixed at one end thatis to be inserted into a female RJ connector, on the side of the external electronicstype 699-02-RJ.11) NOTE:Install the Multirope MRL100 sensor in order to avoid any contact with any part of the lift, likepulleys or hoistway.MRL100 sensor cannot be used in case of high friction between the car and the side guiding railsin the hoistway.Avoid installing MRL sensor on the ropes on the side that takes the load of the counterweight, asthis branch of ropes does not see the load variation inside the cabin. |
