Bearings are sensitive Always handle the encoder with care when handling s and mounting to the mechanism 15 e While conventional hollow shaft rotary encoders affected bearing currents and ground noise the ZapFREE encoder is not The fiber optic connection totally isolates the encoder from these phenomena An isolation insert is unnecessary e The mechanical life of any encoder is mainly determined by the loading on the unit s bearings As either the radial or axial shaft loading increases bearing Page 26 of 94 MICRONOR INC MR310 MR320 Series ZapFREE Encoder System life is shortened Excessive runout will cause premature bearing failure For this reason the minimum amount of shaft loading or misalignment should always be the goal when installing an encoder For applications with fastening points located on variable pitch circle For applications with high axial play For applications with reduced mounting space For applications with axial and radial play with low dynamics for constant rotary movement 104 206 mm MR314B Use Long Spring and Pin MR314B Use Short Spring and Pin MR314B Use Small Tether Bracket and Screw Figure 3 illustrates various mounting options and hardware available for use with MR314 MR324 and ENI100 hollow shaft encoders Page 27 of 94 MICRONOR INC MR310 MR320 Series ZapFREE Encoder System Example of Use Pitch cirde Order Code Di

If one or both LED s do not light up while rotating the encoder shaft then not enough optical power is received or the MR310 input amplifiers have not been calibrated properly e STEP 1 Calibrate the input amplifiers as described in Section 5 7 First Time Start Up and Section 5 8 Manual Gain Calibration Manual Reset If that did not solve the Problem and the LED s do not light up then most likely the fiber optic connection to the encoder is bad e STEP 2 Check Fiber Optic Connections on both the encoder side and the controller side Clean both connectors as described in Section 7 3 Fiber Optic Connector Cleaning e STEP 3 To check if the MR310 produces enough optical power you must have connected to the MR310 and ZAPPY software running and communicating with the MR310 Then disconnect the fiber optic cable from the MR310 and cover the connector interface to protect it from dust e STEP 4 With no optical connection to the MR310 select DIAGNOSTICS mode and all the pertinent diagnostics information should be automatically retrieved from the MR310 The INPUT AMPLIFIER field displays the gain setting of the amplifier and the calculated received optical power for each channel Press the RESET switch on the MR310 located just below J1 to force the ZAPPY GAIN SETTING to 1 maximum gain due to no reflected signal from encoder Get updated AMPLIFIER GAIN setting and calculated OPTICAL POWER by clicking on GET AMPLIFIER GAIN o

If the power reading is lower then 36 5dBm e g 37dBm 38dBm etc then contact Micronor Technical Support as the MR310 unit must be sent in for service or repair Page 72 of 94 MICRONOR INC MR310 MR320 Series ZapFREE Encoder System o If the power levels are gt 36 5dBm e g 36dBm 35dBm etc then proceed to STEP 5 e STEP 5 Clean all optical connector ends and reconnect the encoder and the MR310 module Press the RESET switch on the MR310 located just below J1 WHILE rotating the encoder shaft While rotating the encoder shaft click periodically on DIAGNOSTICS and note the CH A B voltage gain and optical power readings o If the A B voltages are gt 2 1V AND GAINs are 210 AND OPTICAL POWER gt 36 5dBm then the system is working properly and the A B LEDs should visibly flicker when the encoder shaft is slowly rotated o Otherwise suspect the optical cable and or connections to the MR310 and replace the cable with a known Good cable Repeat STEPS 4 and 5 and if the system does not check out properly then suspect the encoder and contact Micronor Technical Support 1 2 Serial Interface If communications cannot be established with a PC proceed as follows e STEP 1 Use the ZAPPY Software from Micronor and check if you can communicate using this software e STEP 2 Make sure you use a correct interface cable The MR310 interface is RS422 RS485 signal based An appropriate interface cable must be used MI
