Torque Measuring Shaft Operating/Assembly instructions 4 KTR-N Sheet: Edition: 49014 EN 9 of 21 7 Assembly 4.4 Assembly of the hubs We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy before assembly. 4.5 Assembly of the RADEX®-NC on the DATAFLEX® torque measuring shaft The power transmission of RADEX®-NC is frictionally engaged by clamping hubs. The following process should be observed with the assembly: • Clean and degrease the contact surfaces of hub bores and shafts before assembly. ! Oils and greases containing molybdenum disulfide or other high-pressure additives as well as internal lubricants must not be used. • Lightly detach the clamping screws. • Insert the shaft ends of the measuring shaft and the driving and driven end into the hubs of the RADEX ®-NC coupling (see illustration 7). • Shift the driving and driven machine in axial direction until the dimension E resp. DBSE is reached. If the power packs have already been firmly assembled, shifting the hubs axially on the shafts allows for adjusting the dimension E or DBSE (see illustration 8). ! When tightening the clamping screws make sure that the torque measuring shaft is not loaded and the hazard of bending or overload by torque can be excluded. Illustration 7: Assembly of clamping hubs ! Illustration 8: Adjusting to dimension E and DBSE With the assembly make sure that the dimension E resp. DBSE (see table 3 and 6) is observed so that the coupling is installed free from distortion in axial direction. Disregarding this advice may cause damage to the coupling. • Tighten the clamping screws of the hub at the tightening torque TA specified in table 5. ! The torques of the clamping hubs of the coupling transmittable via frictional locking are dependent on the bore diameter. Please observe protection note ISO 16016.

General description The measuring shafts type DATAFLEX® 16 are provided with wire strain gauges (DMS) the signals of which are transmitted contactlessly. In addition, a two-channel shaft encoder provides two speed signals shifted by 90 degrees. Each signal has a resolution of 360 periods per revolution. The measuring shaft is connected to the connection housing DF2 via the connection cable which is available as an accessory. The measuring shaft should not be switched on before all connections have been properly connected. After initial switch-on the measuring shaft needs about 5 minutes until the warm-up period is finished and the measurement device has its standard accuracy. 2. Connection housing DF2 The connection housing DF2 has 12 screw terminals to connect power supply, display equipment and switches. The torque signal is displayed as proportional direct voltage from -10 … 10 V. For the speed display two square wave signals, one scalable voltage signal and one direction signal are available (for pin configuration see table 7). The button T1 serves for programming and can be bridged externally against GND via the terminal 12 (T1).

Special functions The following settings can be made by means of sensors: 1) Self-test 2) Measuring range switchover 3) Automatic zero adjustment 4) Manual zero adjustment For safety reasons the settings „1) self-test“ and „2) measuring range switchover“ can only be made up to 15 seconds after powering up. „3) Automatic zero adjustment“ and „4) manual zero adjustment“ can only be made from 15 seconds after powering up. The termination of the 15 seconds period is signalized by short blinking of the LEDs on the connection housing. Illustration 20 5.1 Sensor test The torque sensor can be inspected for operativeness if the sensor T2 is pressed for 2 seconds during the first 15 seconds after powering up the measuring shaft. If the sensor is fine, the output voltage increases to approx. 4 volts for the period of 2 seconds. The output voltage increases to approx -10 volts for 2 seconds in the measuring range 2. • The sensor test can only be performed during the first 15 seconds after powering up.

KTR-N Sheet: Edition: 49014 EN 17 of 21 7 Special functions 5.2 Measuring range switchover The measuring range can be switched over within the first 15 seconds after powering up the supply voltage. For that purpose press the button T1 on the connection housing DF2 during 2 seconds. The selected measuring range is displayed by green LEDs on DF2. Green LEDs off = measuring range 1 (e. g. 100 Nm) Green LEDs permanently on = measuring range 2 (e. g. 20 Nm) The selected measuring range remains set after powering on again. 5.3 Automatic zero adjustment (see illustration 22) If the „push button“ T1 is activated for a period of 2 seconds, the output of the torque signal is automatically set to 0 Volt. The adjusting is effected irrespective of the amount of the actual torque. The termination of the adjustment is confirmed by fast blinking of the LED L1. The new zero point has been saved and the device is in the measuring mode again. • The automatic zero adjustment can only be performed if the measuring shaft is switched on for more than 15 seconds. • If necessary, the automatic zero adjustment can be performed by an external control, too. If the potential of the terminal clamp T1 is connected with GND for 2 seconds, an automatic zero adjustment is performed. Illustration 22: Automatic zero adjustment 5.4 Manual zero adjustment The zero point of the torque output can be adjusted manually. For this purpose both push buttons T1 and T2 are activated simultaneously for 2 seconds. The LED L1 is blinking four times. Pressing the push button T1 increases the voltage, pressing the push button T2 reduces the voltage. The modifications are accelerated if the corresponding push button is permanently pressed. Each amendment is confirmed by short blinking of the LED L2. Having performed the adjusting the new values are lastingly stored by pressing both push buttons again for 2 seconds. The LED L1 is illuminated once and signalizes the return to the measuring mode. The manual zero adjustment can be set separately for the two measuring ranges. The zero point of the range that is currently activated is generally adjusted. Please observe protection note ISO 16016.
