SRM ORIGIN PowerMeter Operation & User’s Manual

authorized dealer visit our website at www.SRM.de. Do not use a mallet to install the PowerMeter as this can damage the electronics which is not covered under warranty. Inspection before installation • Please check that the chain catcher pin of the big chainring aligns with the drive-side crankarm. • Make sure the chainrings sit flat and tight on the 110mm BCD (bolt circle diameter) of the PowerMeter. • Check chainrings bolts of the SRM ORIGIN PowerMeter are torqued to the correct specifications: Shimano chainrings - 12Nm Other manufacturers - 8Nm (check manufacturer specifications) • The drive-side crankarm comes pre-installed at the correct torque specification. WARNING Do not loosen the pinch or crank bolt on the drive-side crank! Failure to do so may result in damage to the product which could result in injury or death. PowerMeter Installation WARNING Failure observe the proper torque specifications can result in damage to the product which can result in injury or death. • Ensure frame has a suitable 30mm bottom bracket installed when mounting the SRM ORIGIN PowerMeter. Compatible bottom brackets can also be purchased from an SRM authorized dealers or our online shop at: www.SRM.de. • Install Bottom Bracket per manufacturers instructions, ensuring sealing rings are placed properly and bearings are fully seated and concentric in frame. • Determine the required spacers for the Drive and Non-Drive side according to your bottom bracket type - check table (Fig. 11). • Install the corresponding spacers onto the drive side axle (Fig. 1) and apply a small amount of grease to the contact surfaces of the bearing/axle. Due to tight tolerances the axle/bottom bracket can be difficult to install if not inserted straight. Carefully align the spindle with both bearings and with a slight rocking motion use light pressure to fully seat crank in the bottom bracket. Make sure that the Non-Drive Side bottom bracket does not come loose or even come out of the BB shell. • Remove the excess grease from the non-drive side of the crank axle and position the appropriate spacers according to the table (Fig. 11). When installing the non-drive crank, make sure that the crank is rotated by 180 ° to the drive-side crankarm. • Apply a light thread locker (violet) to the threads of the axle bolt and slightly tighten with a 10mm allen key (Fig. 2). NOTICE Make sure that the axle bolt is only slightly tightened till the spacers touch the bottom bracket and the bottom bracket is free of play. Excessively high tightening forces can bring lateral pressure to the bearing and lead to increased bearing wear and and possibly damage the bottom bracket over time. • Unscrew the non drive side crank bolt counterclockwise and place a small drop of light thread locker (violet) on the threads. Re-torque the bolt to max. 5-6Nm (Fig.3.1). • Tighten the left axle bolt counterclockwise with a torque of 5Nm (Fig.3.2). • Let the thread locker cure for at least 6 hours before use! Pedal installation / Choose crank length • The crank length can get adjusted from 170, 172.5 to 175mm. Make sure you select the correct crank length! • Degrease and clean the Tri-lobe nut, Tri-lobe washer and the contacting crank surfaces. Dust and/or any other particles on the Tri-lobe nut or on the crank could damage the crank or the pedal threads. • Make sure to use the correct Tri-lobe nut marked with “R“ when installing the Drive-Side pedal (Fig. 5). • Position the arrow on the Tri-lobe washer facing the marking of the desired length. Make sure the washer is aligned correctly and sitting flush inside the crank (Fig. 4). Insert the Tri-lobe nut from the backside. Make sure the holes of the washer and nut are concentric with each other. • Proceed accordingly with the Tri-lobe nut marked with “L“ on the Non-Drive side crankarm (Fig. 6). • Tighten the pedals with the recommended torque: 20 - 40Nm (check pedal manufacturer specifications). WARNING Failure to observe the correct torque specification can result in damage to the product which can result in injury or death. Danger of accident due to failure of the crank system due to loosened screw connections. Check the correct torque specifications of all screw connections after the first 100km ride and then at regular intervals of 2.500km. If necessary, re-tighten the screws and/or replace thread locker if necessary! PowerMeter PM-SRM-VAR-AXL-SH4-110-010 FIG. 4 FIG. 5 FIG. 1 FIG. 6 FIG. 3 1. 2. FIG. 2

Cadence Magnet Installation Before assembly • The cadence magnet must be installed properly in order for the PowerMeter to turn on and measure cadence. • The recommended position for the cadence magnet is on the underside of the bottom bracket. • Make sure the magnet is positioned between 21-51 mm from the center point of the bottom bracket shell. (Fig. 7). • If your frame geometry does not allow for these magnet positions, visit our store at www.SRM.de for integrated chain catcher magnets and additional mounting options. Option 1: For frames with a cable guide • Remove the cable guide bolt and install the magnet under the cable guide (Fig. 8). • To assist with cable guide removal, shift the chain into the largest cog in the rear and the largest chainring in the front. Next, without turning the cranks, shift both derailleurs to the smallest cog. This will remove tension from both cables. • Position the magnet 4-6 mm from the backside of the PowerMeter (Fig. 9). • Install the bolt and tighten it to the torque specified by the frame manufacturer - you may need a longer screw to securely hold the cable guide and magnet in place. NOTICE The derailleurs may require some adjustment after cadence magnet installation. Option 2: For frames without a cable guide • Clean both the magnet and the mounting surface of the frame with the isopropanol alcohol. • Position the magnet 4-6 mm from the backside of the PowerMeter (Fig. 10). NOTICE It is recommended to temporarily fix the magnet in place and confirm correct position before installing with the double sided tape. Check the functionality of the PowerMeter before gluing the magnet! • Use the double sided tape to install the cadence magnet to the frame. Remove the protective film on each side of the tape. Avoid touching the adhesive surfaces. Glue the magnet in the correct position. • To achieve optimal magnet position, the cadence magnet and double sided tape can be cut with scissors to fit your desired location. Connection • For information on connecting the SRM ORIGIN PowerMeter to your SRM PowerControl or other third party ANT+ devices, please refer to the device manual. NOTICE Make sure your PowerMeter is turned on when pairing to other devices! Spin the crank 1-2 revolutions to turn the PowerMeter on! Check cadence magnet placement to ensure function! Battery Test / Replacement • The SRM ORIGIN PowerMeter broadcasts the battery status to the SRM PowerControl or other compatible ANT+ devices. You will get notified if the battery is running low! • See our authorized dealers or us directly at www.SRM.de for a battery replacement. WARNING Danger of explosion, in case of improper opening of the PowerMeter or replacement of the battery. NOTICE Unauthorized opening and closing of the PowerMeter can lead to water leakage and permanently damage. The SRM ORIGIN PowerMeter is equipped with lithium batteries which can only get replaced by authorized SRM Dealers or the SRM Service Centers!
